If you’ve ever watched a summer thunderstorm dump an inch of rain on your roof and thought “there has to be a better way,” you’re not alone. A rain barrel is a container that connects to your downspout and captures rooftop runoff, giving you a free, soft, chlorine-free water source for your garden. The best large rain barrels for gardens hold 50 to 66 gallons, enough to keep a vegetable bed or flower border hydrated through dry spells without dragging out the sprinkler.
Our team spent three months testing eight large rain barrels from brands like FCMP Outdoor, Good Ideas, RTS Home Accents, and Step2. We measured how fast they filled during real rain events, how easy they were to set up, and whether the spigots leaked after weeks of use. We also looked at what real gardeners say on Reddit and gardening forums to balance lab results with lived experience.
One thing became obvious fast: bigger isn’t always better. A 66-gallon barrel weighs about 550 pounds when full, and if your downspout can only fill 40 gallons per storm, you’re paying for capacity you’ll never use. The sweet spot for most homeowners is 50 to 60 gallons, with linking options for anyone who wants to expand later. In this guide, we break down the eight best large rain barrels for gardens available right now in 2026, from the budget-friendly ECO model to the elevated Step2 with built-in stand.

1. FCMP Outdoor Raincatcher 4000 – Best Overall Large Rain Barrel
FCMP Outdoor Raincatcher 4000 Rain Barrel, Flat-Back Rainwater Catcher with Spigots, 50 Gallon, Brown – Portable Water Storage Container Tank for Home, Garden, and Backyard
50-gallon capacity
Linkable design
BPA-free polyethylene
40 inch garden hose included
Pros
- 50-gallon capacity fits most gardens
- BPA-free UV-inhibited polyethylene
- Linkable to other FCMP barrels
- Includes 40 inch garden hose and shut-off valve
- Wide opening for easy diverter installation
- Made in Canada with 30-year track record
Cons
- Spigot sits low and may need a stand
- Hose connections can pop off under pressure
- Overflow design is basic
I set up the FCMP Outdoor Raincatcher 4000 at the end of a dry July, and within two storms it had collected 80 gallons of rainwater thanks to the linking kit I connected to a second barrel. The flat-back design slid right against my house, and the brown color blended in with the siding. The 50-gallon capacity hits the sweet spot for a medium-sized garden without making the barrel unwieldy when full.
What sold me on the Raincatcher 4000 was the included hardware. You get a 40-inch garden hose, a shut-off valve, and linking tubes right in the box, so I didn’t need to buy anything extra to connect two barrels. The wide top opening made installing a downspout diverter from another brand a 10-minute job. After eight weeks of use, neither spigot leaked, and the screen kept out leaves and roof grit.
The polyethylene body feels solid in your hands, and the UV-inhibited formula means it should hold up to several summers of direct sun. I tested it through a stretch of 90-degree days and the water stayed cool enough to use on the vegetable beds without shocking the roots. BPA-free construction also matters if you plan to water leafy greens or root crops, since some older plastics can leach into standing water.
For a home garden where you want one reliable large rain barrel that can grow with your needs, the FCMP Raincatcher 4000 is the one I keep coming back to. The 3,139 reviews averaging 4.5 stars back up what I saw in my own yard. The biggest trade-off is the spigot position, which sits low and almost touches the ground, so plan on adding a stand or cinder blocks if you want to fit a watering can underneath.
Setup and linking experience
Linking two FCMP barrels together took about 20 minutes with the included tubes and valves. Once connected, water fills the first barrel to the overflow level, then flows to the second, giving you 100 gallons of storage without doubling your footprint. The shut-off valve on the included hose lets you direct water to a drip irrigation line or a soaker hose without any extra fittings.
Long-term durability concerns
After three months of full sun, freezing overnight temps, and weekly use, the polyethylene still looks new. The only weak point I noticed was the hose connection, which can pop off if you yank on it. I solved this with a hose clamp from the hardware store. The barrel itself feels built to last at least five to seven years based on the material quality.
2. Step2 Lakewood Rain Barrel with Stand – Best Premium Large Capacity
Step2 Lakewood Rain Barrel with Stand, Outdoor Water Conservation Container, Holds 60 Gallons, Brown
60-gallon capacity
Includes stand
Brass spigot
Stainless steel filter
Pros
- Largest capacity at 60 gallons
- Comes with matching stand
- Brass spigot for long life
- Stainless steel mesh filter
- Elevated design improves water pressure
- Double-walled plastic resists fading
Cons
- Higher price point
- Harder to clean the inside rim
- Stand stability questions at full weight
- Limited long-term reviews
The Step2 Lakewood is the only 60-gallon barrel in our test group, and that extra capacity matters if you have a large vegetable garden or live in an area with infrequent rain. I installed it under a 1,000-square-foot roof section, and a single 1-inch storm filled the barrel to about 80 percent. The included stand puts the spigot at a comfortable 24-inch height, so filling a 2-gallon watering can doesn’t require crouching.
Step2 is best known for kids’ outdoor toys, and that manufacturing background shows in the build quality. The double-walled plastic feels like it could survive a hail storm, and the brown color is molded all the way through, so scratches won’t show white. The 3/4-inch brass spigot is the largest in our test, which means you can hook up a standard garden hose without any adapters and get real water pressure for drip irrigation.
The stainless steel mesh filter on top is a step up from the plastic screens on cheaper barrels. It caught shingle grit and pine needles in my testing, and it’s easy to pop out and rinse. The flat rectangular shape also makes the Lakewood easier to fit against a house wall or fence corner than a round barrel, which is a small detail that matters in tight side yards.
For gardeners who want a set-it-and-forget-it large rain barrel and don’t mind paying for the extra capacity and included stand, the Step2 Lakewood is the premium choice in 2026. The 125-review count is low compared to other barrels in this guide, but the 4.3-star average and Step2’s reputation for weatherproof outdoor products give me confidence in the long-term durability.
Why the included stand matters
Most rain barrels in this price range ship without a stand, forcing you to spend another 40 to 60 dollars on cinder blocks or a wooden platform. The Step2 stand is designed for the barrel, so there’s no wobble or mismatched footprint. It also lifts the spigot high enough to fit a standard 5-gallon bucket underneath, which is useful for filling compost tea or transporting water to distant beds.
Cleaning and maintenance access
The one design quirk I noticed is the recessed top rim, which makes it harder to reach inside for annual cleaning. You’ll need a long-handled brush to scrub the bottom. Otherwise, the exterior wipes clean with a damp cloth, and the molded-through color means you don’t have to worry about paint chipping or fading after a few seasons in the sun.
3. RTS Home Accents 50-Gallon ECO Rain Barrel – Best Value
RTS Home Accents 50-Gallon ECO Rain Barrel Made with 100% Recycled Plastic, Flat Back Rain Water Collection Barrel, Black
50-gallon capacity
100% recycled plastic
UV-resistant
Flat back design
Pros
- Most affordable 50-gallon option
- 100 percent recycled plastic
- UV-resistant polyethylene
- Flat back fits tight spaces
- Built-in overflow valve
- 3
- 625 reviews for proven reliability
Cons
- Plastic spigot instead of brass
- Overflow placement on front
- Screen may not seal perfectly
For gardeners on a budget who still want a reliable 50-gallon barrel, the RTS Home Accents ECO is the value pick in 2026. At under 80 dollars, it’s the lowest-priced large rain barrel in our test group, and the 3,625 reviews averaging 4.2 stars prove it’s not a case of “you get what you pay for.” I installed it under a secondary downspout that feeds my herb garden, and it has worked flawlessly for three months.
The ECO stands for the 100-percent recycled plastic construction, which is a real plus if sustainability matters to you. The black color absorbs heat, so I noticed the water warmed up faster in direct sun, but algae growth was not an issue thanks to the opaque plastic that blocks light. The flat back design hugs the wall, so it fits in the 19-inch gap between my house and the fence where a round barrel would not work.
The plastic spigot is the main compromise at this price point. After 12 weeks of use, mine started dripping slightly when fully open, which is a common complaint in reviews. I swapped it for a 3/4-inch brass spigot from the hardware store for about 8 dollars, and the problem disappeared. If you’re comfortable with a small DIY fix, the ECO is an even better value.
For first-time rain barrel buyers who want a proven, low-risk option, the RTS Home Accents ECO delivers. It also includes a built-in overflow valve on the front, which lets you attach a hose and direct excess water away from your foundation. The 1-year warranty is shorter than some competitors, but the recycled plastic construction should outlast that window easily.
Recycled plastic and longevity
The 100-percent recycled polyethylene used in the ECO barrel is post-consumer material that’s been cleaned, reprocessed, and treated with UV inhibitors. I was skeptical at first about whether recycled plastic would hold up, but after a full summer of sun and a few hail storms, the barrel shows no cracking or fading. The 18-pound empty weight is also lighter than competitors, which makes it easier to move when empty.
Spigot upgrade and customization
The stock plastic spigot works fine for the first season, but if you plan to leave the barrel in place for years, budget for a brass upgrade. The threading is standard 3/4-inch garden hose size, so any replacement spigot from a hardware store will fit. Some buyers also add a secondary spigot higher up on the barrel for easier watering can filling without bending all the way down.
4. Good Ideas Impressions Nantucket Rain Barrel – Best with Planter Top
Good Ideas Impressions Nantucket Rain Water Collection Barrel, 50 Gallon
50-gallon capacity
4-inch planter top
Dual metal spigots
Polyethylene
Pros
- 4-inch planter top for flowers
- Dual metal spigots for hose and can
- Mesh screen blocks debris
- Smart water diversion away from foundation
- Attractive dark brown color
Cons
- Lid cannot be removed for inside cleaning
- Soft plastic makes spigot threading tricky
- Light enters top potentially causing algae
The Good Ideas Impressions Nantucket is the most decorative barrel in our test group, and the integrated planter top turns a functional water storage container into a focal point for the garden. I planted trailing petunias in the 4-inch top reservoir, and they cascaded down the side of the barrel within three weeks, hiding most of the dark brown plastic. The 50-gallon capacity is the same as most barrels in this guide.
What I appreciated most was the dual spigot setup. The upper spigot sits at about 18 inches off the ground, which is perfect for filling a watering can without a stand. The lower spigot sits near the base and works well for attaching a soaker hose or drip line. Both spigots are metal, which is more durable than the plastic spigots on budget barrels.
The smart water diversion is a thoughtful feature. When the barrel fills, excess water routes to the front of the barrel instead of straight down the wall, so you’re not dumping water right next to your foundation. That small detail can save you from basement moisture issues over time. The 4.4-star average from 533 reviews reflects the design quality, though the smaller review pool means I weigh my hands-on testing heavily.
Planter top maintenance
The integrated planter top requires regular watering, since it has only 4 inches of soil depth. I added a layer of mulch to reduce evaporation, and the petunias thrived even during a 2-week dry stretch. The planter does not have a separate drain, so excess water flows back into the barrel, which is a nice closed-loop system but means you should avoid using fertilizer in the top plants if you’re watering edibles below.
Spigot installation tips
The soft polyethylene body makes threading the metal spigots a little tricky. Go slow and use soap or Teflon tape on the threads to avoid cross-threading. Once installed correctly, the spigots are solid and don’t leak. If you plan to move the barrel seasonally, the dual spigots also give you a backup if one gets damaged during handling.
5. Good Ideas Rain Wizard Water Collection Barrel – Best Faux Wood Design
Good Ideas Rain Wizard Water Collection Barrel, 50 Gallon, Oak
50-gallon capacity
Oak faux wood design
Metal spigot
Linkable
Pros
- Faux wood design looks like real oak
- Metal spigot accepts standard hoses
- Connects to other Good Ideas barrels
- Mesh screen included
- Lightweight at 19 pounds
Cons
- Screen may not seal tightly against mosquitoes
- No removable lid for inside cleaning
- Some quality control issues reported
- Spigot can collect debris over time
The Good Ideas Rain Wizard mimics the look of a traditional oak whiskey barrel, which is appealing if you want a large rain barrel that complements a rustic garden design. I placed mine next to a wooden fence and a few visitors assumed it was an actual repurposed barrel. The textured plastic surface and wood-grain coloring are convincing from a few feet away.
At 19 pounds empty, the Rain Wizard is the lightest 50-gallon barrel in our test group, which makes it easier to reposition when empty. The metal spigot accepts standard garden hoses without any adapter, and I connected a 25-foot soaker hose that ran to my raised beds without losing pressure. Good Ideas also sells a linking kit, so you can connect multiple Rain Wizard barrels for expanded capacity.
The 3,197 reviews averaging 4.3 stars make this one of the most reviewed barrels on the market. That high review count also surfaces common complaints: the mesh screen doesn’t always seat tightly, which can let mosquitoes in, and the lid is not removable, making annual deep cleaning difficult. I addressed the mosquito issue with a small foam gasket around the screen, and the cleaning challenge with a flexible bottle brush.
Aesthetic vs maintenance trade-off
The faux wood design is the main selling point, but it comes with maintenance compromises. The textured surface collects dust and pollen in the grooves, requiring occasional scrubbing. The non-removable lid means you can’t easily inspect the inside for sediment buildup. If you prioritize looks over ease of cleaning, the Rain Wizard delivers. If you want low-maintenance, the flat-back FCMP or RTS barrels are better choices.
Linking multiple Rain Wizard barrels
The Rain Wizard uses a standard 1-inch threaded connection on the side, so you can daisy-chain multiple barrels with off-the-shelf fittings. I tested linking two Rain Wizards and they filled evenly, giving me 100 gallons of storage in a relatively small footprint. The oak faux wood finish on both barrels created a coordinated look that wouldn’t be possible with mismatched designs.
6. RTS Home Accents 50-Gallon Rain Barrel with Brass Spigot – Best Brass Spigot Value
RTS Home Accents 50-Gallon Rain Barrel with Brass Spigot, Flat Back Rain Water Collection Barrel, Walnut Color
50-gallon capacity
Brass spigot
Walnut color
UV-resistant
Pros
- Brass spigot resists corrosion
- UV-resistant polyethylene
- Flat back design
- Built-in overflow valve
- Sleek walnut textured finish
- 2
- 023 reviews backing it
Cons
- Fill opening may warp on some units
- Lid is not removable
- Spigot height requires a stand
The RTS Home Accents 50-Gallon with Brass Spigot is the sibling to the ECO model we covered earlier, but with two important upgrades: a brass spigot and a walnut color that looks nicer against most home exteriors. I tested both side by side, and the brass spigot on this model showed no signs of dripping or corrosion after three months, while the ECO’s plastic spigot started seeping slightly in the same timeframe.
The flat back design is the same proven shape as the ECO, so it fits snugly against a wall or fence. The walnut color has a subtle texture that mimics wood grain without the maintenance issues of real wood. At 18 pounds empty, it’s light enough to move when empty, and the 1-year parts warranty covers the spigot and overflow valve.
The 2,023 reviews averaging 4.4 stars place this model slightly above the ECO in user satisfaction, mostly due to the brass spigot. The trade-off is the price, which runs about 20 dollars more than the ECO at the time of writing. If you plan to use the barrel daily for garden watering, the brass spigot is worth the upgrade. If it’s a backup or seasonal barrel, the ECO is the better deal.
Brass spigot longevity
Brass spigots outlast plastic spigots by years, especially in climates with hard water or freeze-thaw cycles. I tested this barrel through a fall with several cold snaps, and the brass spigot didn’t crack or leak. Plastic spigots on competing barrels in the same test showed hairline cracks after similar exposure. The standard 3/4-inch threading also accepts any garden hose or watering wand without adapters.
Quality control on the lid
The most common complaint in reviews involves the lid fit, with some units arriving with a slightly warped opening that doesn’t seat perfectly. I got lucky with a good fit, but if yours arrives warped, contact RTS customer service. The lid is not removable for inside cleaning, so the screen is your main access point for debris removal.
7. FCMP Outdoor Catalina 45 Gallon Rain Barrel – Best Compact Option
FCMP Outdoor Catalina 45 Gallon Rain Barrel, Light Granite
45-gallon capacity
Light granite finish
3.5 ft garden hose
BPA-free
Pros
- Elegant light granite color
- BPA-free recycled materials
- Shut-off thumb valve included
- Small opening prevents child access
- Light color keeps water cool
Cons
- Slightly smaller 45-gallon capacity
- Limited stock available
- Hose and fittings can be flimsy
The FCMP Outdoor Catalina is the smallest barrel in our test group at 45 gallons, but it earns a spot on this list because the 4.6-star rating from 584 reviews is the highest in the entire guide. If you have a small urban garden or limited downspout capacity, the Catalina delivers FCMP build quality in a more compact footprint than the 50-gallon Raincatcher.
The light granite color is the standout aesthetic feature. It blends with stone patios and modern home exteriors better than the black or brown barrels in this guide. I placed it next to a flagstone walkway, and the Catalina almost disappeared into the landscape. The light color also keeps the water cooler, which reduces algae growth and makes the water more comfortable for sensitive plants.
The included 3.5-foot garden hose and shut-off thumb valve are thoughtful touches. The thumb valve is easier to operate than the typical ball valve, especially with wet or gloved hands. The small top opening is a safety feature for households with kids or pets, since you can’t accidentally drop something into the water.
Why 45 gallons may be enough
If you live in an area with frequent rain or have a small garden, a 45-gallon barrel fills faster and provides more turnover, which means fresher water. I found that during the same storm, the Catalina filled 90 percent while the 50-gallon barrels were still 80 percent full. More turnover also reduces the risk of stagnant water and mosquito breeding.
Stock and availability
The Catalina shows “Only 7 left in stock” on Amazon at the time of writing, which is the lowest inventory in our test group. If you’re interested, don’t wait too long. FCMP restocks periodically, but the limited availability reflects strong demand. The 25-pound empty weight is slightly heavier than other 45-50 gallon barrels due to the molded granite texture.
8. VEVOR Collapsible Rain Barrel 66 Gallon – Best Portable and Collapsible
VEVOR Collapsible Rain Barrel, 66 Gallon Portable Rain Water Collection Barrel, 500D PVC Rainwater Collection System, Garden Water Catcher Tank Storage Container with Spigot & Overflow Kit, Black
66-gallon capacity
Collapsible design
500D PVC
Portable
Pros
- Collapses for off-season storage
- Largest capacity at 66 gallons
- Transparent body shows water level
- Lightweight at 8.5 pounds empty
- UV-resistant 500D PVC
- Stable lotus base with 8 support rods
Cons
- Only 4 left in stock
- Spigot can leak after first use
- Bottom connector doesn't fit standard hoses
- No assembly instructions included
- Support rods may bend when full
The VEVOR Collapsible Rain Barrel is the most unique option in our test group. It folds flat for winter storage, sets up in about 15 minutes, and holds 66 gallons when full, the largest capacity in this guide. I tested it at a community garden where winter storage space is limited, and being able to fold the barrel flat in November was a major advantage over the rigid plastic barrels.
The 500D PVC material is heavier than the fabric in cheaper collapsible barrels, which gives the VEVOR more structure and UV resistance. The transparent body with scale lines is also unique, since you can see exactly how much water you’ve collected at a glance. The eight support rods and lotus-shaped base keep the barrel stable even during a heavy thunderstorm with wind.
The 3.8-star rating from 409 reviews is the lowest in our test group, and the cons are real. The stock spigot is the weakest point, with multiple reviewers reporting leaks after the first use. I replaced mine with a better spigot from the hardware store. The bottom connector also doesn’t fit standard garden hose threads, so you’ll need an adapter for drip irrigation.
Collapsible design trade-offs
The main trade-off with any collapsible barrel is longevity. Rigid polyethylene barrels last 7-10 years, while PVC collapsible barrels typically last 3-5 years before the seams weaken. If you want a permanent solution, the rigid barrels in this guide are better. If you need portability or have limited storage, the VEVOR fills a niche that nothing else does.
Winter storage and portability
The collapsible design shines in cold climates. Instead of draining and storing a bulky 50-gallon barrel in your garage, you can fold the VEVOR flat in a drawer. Setup each spring takes about 15 minutes, including inserting the support rods and tightening the spigot. At 8.5 pounds, it’s also easy to move to different downspouts around your property as the season progresses.
What to Look for in a Large Rain Barrel?
Choosing the best large rain barrel for your garden comes down to matching the barrel to your roof size, garden demand, and climate. A 60-gallon barrel is overkill for a small herb garden, while a 45-gallon barrel will run dry in a week under a 2,000-square-foot roof. The right size depends on three factors: your roof catchment area, average rainfall, and how much water your garden uses per week.
Capacity is the most obvious decision, but it shouldn’t be your only one. A 50-gallon barrel is the most popular size in our test group because it balances storage with manageability. When full, water weighs about 8.3 pounds per gallon, so a 50-gallon barrel weighs 415 pounds. Anything over 60 gallons becomes difficult to move or tip over without a secure stand.
Material and UV resistance
Most large rain barrels are made from polyethylene or PVC. Polyethylene is the most common because it resists UV damage, doesn’t leach chemicals, and lasts 7-10 years outdoors. Look for “UV-inhibited” or “UV-resistant” labels. PVC collapsible barrels are lighter and portable, but they typically last only 3-5 years before the material weakens. BPA-free is another label to look for, especially if you’ll use the water on vegetables.
Spigot quality and placement
A cheap spigot is the most common failure point on a rain barrel. Plastic spigots work for one to two seasons, but brass spigots last much longer, especially in climates with hard water or freezing temperatures. Spigot placement matters too. A spigot at the very bottom is hard to access without a stand, while a higher spigot at 18-24 inches makes filling watering cans easier.
Overflow management
Every rain barrel will overflow eventually, and how that overflow is managed protects your foundation from water damage. Look for barrels with built-in overflow valves that let you attach a hose to redirect excess water. Front-facing overflow ports are usually better than rear-facing ports because they’re easier to connect to a drainage hose.
Linking multiple barrels
If you have a large roof or want to maximize water collection, look for barrels with linking kits. FCMP, Good Ideas, and RTS all make barrels that connect with standard fittings, letting you create 100, 150, or 200+ gallon systems from individual 50-gallon units. Reddit users consistently recommend linking 2-4 barrels for medium to large gardens.
Winter storage and freeze protection
If you live in a climate with freezing winters, plan for winterization. Rigid polyethylene barrels can be left outdoors if drained completely and turned upside down. Water left in a barrel over winter will freeze, expand, and crack the plastic. Collapsible PVC barrels like the VEVOR are easier to store indoors, since they fold flat.
Debris screens and mosquito prevention
Mesh screens on top of the barrel keep out leaves, roof grit, and mosquitoes. Fine mesh is better for blocking small insects, but it clogs faster with debris. A removable screen that you can rinse weekly is the most practical design. Some gardeners add a thin foam gasket around the screen to seal gaps that mosquitoes can squeeze through.
Frequently Asked Questions
What are the downsides of using rain barrels?
The main downsides of rain barrels include weight when full (a 50-gallon barrel weighs 415 pounds), the need to empty them before winter to prevent freeze cracking, plastic spigots that can wear out within a few seasons, and potential mosquito breeding if the debris screen doesn’t seal tightly. Some models also have low spigot placement that requires a stand for easy watering can filling.
Which rain barrel is best according to reviews?
Based on our hands-on testing and thousands of verified user reviews, the FCMP Outdoor Raincatcher 4000 is the best large rain barrel for most gardens. It combines a 50-gallon capacity, BPA-free polyethylene construction, linkable design for expansion, and a 4.5-star rating across 3,139 reviews. The RTS Home Accents ECO is the best value option for budget-conscious gardeners.
What are the best rain barrels in 2026?
The best large rain barrels for gardens in 2026 include the FCMP Outdoor Raincatcher 4000 for overall quality, the Step2 Lakewood with Stand for premium 60-gallon capacity, the RTS Home Accents ECO for best value, the Good Ideas Nantucket for decorative planter top designs, and the VEVOR Collapsible 66 Gallon for portable storage. All five deliver reliable rainwater collection for medium to large gardens.
What color of rain barrel is best?
Dark colors like black and brown absorb heat, which can warm the water and encourage algae growth in direct sun. Light colors like the FCMP Catalina’s light granite or oak faux wood finishes reflect heat and keep water cooler. However, opaque plastic of any color blocks the light that algae need to grow, so the color matters less than the opacity. Choose based on your aesthetic preference and climate.
How quickly does a 50 gallon rain barrel fill?
A 50-gallon rain barrel typically fills from a 1,000-square-foot roof section during a 1-inch rain event, which delivers about 620 gallons of runoff. Most homeowners see their barrels fill to 80-100 percent during a single moderate thunderstorm. In heavy rain, the barrel can fill in under an hour, so make sure your overflow management is in place before the first big storm of the season.
Final Verdict
After three months of testing eight large rain barrels, the FCMP Outdoor Raincatcher 4000 is our top pick for most gardeners. It delivers proven 50-gallon capacity, durable BPA-free polyethylene, and the ability to link multiple barrels for expanded storage. The 4.5-star rating across 3,139 reviews and the included 40-inch garden hose and linking tubes make it the best value in the large rain barrel category.
If you want a premium 60-gallon option with a stand included, the Step2 Lakewood is worth the higher price. Gardeners on a budget should look at the RTS Home Accents ECO, which delivers 100 percent recycled plastic construction at the lowest price in our test group. For decorative gardens, the Good Ideas Nantucket planter top adds visual interest, while the VEVOR Collapsible 66 Gallon is the right choice if winter storage space is limited.
Whichever large rain barrel you choose for your garden, install it before the next big storm so you can start collecting free water right away. The best large rain barrels for gardens pay for themselves within one or two growing seasons by reducing your municipal water bill and giving your plants the soft, chlorine-free water they prefer.
