OUR TOP 7 RECOMMENDED PLASTIC SHEDS
1. Keter Scala Outdoor Plastic Garden Storage Shed
The Keter Scala Outdoor Plastic Garden Storage Shed is a durable 6ft by 5ft shed that’s large enough to hold all the garden equipment from a regular domestic garden. The built-in floor base keeps everything clean and dry. Its also worth mentioning that this shed is also available in some larger sizes too so if you like the design of this shed but need a larger model, bear this in mind.
Constructed of a long-lasting resin, the textured brown double-walled panels are weatherproof, fade-free and extremely low maintenance. Just wash or hose them down every so often to remove the dust and grime. You will probably notice the wood effect looks amazing good compared to some of the alternative wood effect designs we have seen. Keter has done a really good job with this model in that respect.
Double doors in the front wall give full access to the interior, while the fixed windows in the doors bring in natural lighting. Air circulation inside the shed is ensured by the vent above the doors which is a feature we always look for in sheds to help reduce condensation. You can lock the doors as long as you provide your own padlock but what we will say is that most plastic sheds also have plastic latches for the locks,this model actually uses a steel latch which is much more secure than the usual locking latches on most other plastic sheds.
You’re on your own about how you organise your things inside this shed as some online reviewers report that it’s not possible to attach shelves to the interior walls. WE recommend checking out of garage shelving review as some of them would be perfect for using in this shed.
- Wood effect plastic shed has rustic look panels with back-to-nature appeal.
- Double wall construction is fully weatherproof for all season use.
- Floor panel keeps all your stuff off the ground so that it stays dry.
- Double lockable doors, each with a fixed paneled window to let some light into the inside.
- Vent above the door for air circulation inside to stop mould from growing.
- Not able to fix shelves to the wall. (use free-standing shelves)
The Keter Scala Outdoor Plastic Garden Storage Shed is from a high-quality manufacturer of garden sheds and they have really made improvements with this model when I compare it to some of there earlier models. Just a side note, I think their earlier models are still better than some of the plastic alternatives still available today from other manufactures.
This 6ft by 5ft model is large enough for the usual domestic gardener to store their tools and some equipment. The brown resin panels have a stylish darker brown trim so this shed has some visual appeal which I like. The double doors open almost fully to the interior of the shed and you receive the base floor with your purchase.
The Keter Scala Outdoor Plastic Garden Storage Shed is our Best Pick and we stand by it. We like its solid construction and that it has all you need t safely and cleanly store your garden tools and some patio decor. This is a good choice for anyone looking for garden storage space. don’t forget, it’s also available in a couple of sizes.
2. Lifetime 15ft W x 8ft D Apex Plastic Shed
The Lifetime 15ft. W x 8ft. D Apex Plastic Shed offers space and superior strength when it comes to construction. This is one of the best plastic shed brands we have seen, easily on par with Keter. This plastic shed is designed beautifully adding a touch of décor to your garden and a great conversation piece when you have company over. The shed is made from heavy density polyethylene which is strong and very durable. Maybe more importantly for some people, it’s very low maintenance with no painting and treating worry about.
It’s easy for you and your garden tools to enter the shed through the central strong double doors in the long wall, or the double doors in each of the end walls. You can lock these steel-reinforced doors to keep your stuff safe, which for most people is a must. This model is designed to withstand the outdoors because it is UV treated so it will not fade; it’s also fire-resistant. No matter how cold or how hot it gets, you can rest easy knowing that your items are protected in a shed that handles just about whatever mother nature (and life) throws at it.
It’s easy to see what you stored at the back of the shed thanks to the two skylights and the windows installed. The windows are shatterproof making it safe for young children to play around them. Their material is more durable in general and much more secure than glass.
The roof is supported by steel trusses to give it extra stability and strength. No water will collect on the roof during heavy rain. However, it’s advisable to clear snow away because of its weight that can issues on the roof, a common problem with sheds. There is a reinforcement kit to strengthen the roof but still sweep it clear yourself if you do regularly get heavy snow, such as in Scotland.
This American-made shed is well ventilated preventing the accumulation of odours. This easy to assemble shed requires low maintenance and offers longevity of service. You may need an extra pair of hands during assembly to make the process run faster as it can be a little awkward to manage the sides on your own. The assembly instructions are a bit wanting in detail but nonetheless manageable. However, some online reviewers report that it takes at least two people up to 10 hours and intense concentration to put this shed together, even after watching the YouTube video. So be prepared!
We recommend this model for those who require a sizable premium shed that has aesthetic appeal.
- Premium shed made from heavy density polyethylene that looks like a little cottage or playhouse in your garden.
- Easy to access through the double doors in the long wall and a single door in one end.
- Doors are reinforced with steel to give you’re the utmost security for the garden tools and machines inside.
- The structure is UV-treated to prevent fading and also fire resistant to keep everything as it is.
- Two shatterproof windows in a long wall and two skylights in the roof let natural light in so you can see what you’re doing inside.
- The roof is supported by steel trusses to withstand some weight from the snow.
- Comes with shelves to start your organisation tasks.
- Dimensions: 457cm (length); 244 (width); and 241cm (height)
- Difficult to assemble, even with YouTube video
If you require something that provides unbeatable strength design-wise then the Lifetime 15 Ft Apex Plastic Shed is appropriate and well worth considering. Made from high-density polyethylene, this shed can withstand impact and the elements. Both the doors and the roof are supported by steel reinforcements, making the structure strong compared to models that just use plastic alone. It comes with all the necessary parts including a floor and shatterproof windows. All in all, this model suits many gardens as long as there is adequate space.
The Lifetime 15 Ft Apex Plastic Shed is our choice for Runner-up in our review. Yes, it’s a little more expensive than some other sheds, but if you’re looking for a large plastic garden shed with a strong visual appeal, this model is well worth considering.

3. Keter 6ft x 6ft Factor Shed
The Keter Factor line of sheds comes in a variety of sizes all with the same outstanding quality and features as other Keter products. We chose the 6 x 6ft shed for this review as it’s a good size for all the tools that the regular domestic gardener has. Plus some extra room for kids’ bikes, a paddling pool and so on.
The Keter Factor shed is built from the quality materials you expect from a Keter shed. It has a steel-reinforced structure and a hard and robust floor. The all-important roof skylight and side window allow natural more light into the shed so you can find things more easily. The outside of the shed has a texture that adds visual interest, but we’re not convinced that it looks like the advertised wood grain.
Two opening doors in the front wall make storing large items easy. This model comes with two shelves so you can put your tools and other small items out of the way where they’re easy to find.
- The high-quality materials and construction of this shed live up to the Keter brand name.
- Double doors in the front wall make storing large items straightforward.
- Steel reinforced structure for safety and security as well as longevity.
- Single window and skylight let in natural light for good visibility.
- Two shelves are included to start you on your quest for a tidy shed.
- Vent to ensure good air circulation to prevent nasty smells from building up.
- A heavy-duty floor panel is included so ensure you have level ground to put the shed on.
- (external) 182cm (length); 257cm (width); and 243cm (height);
- (internal): 162cm (length); 237cm (width); and 239cm (height)
- Need to provide your own padlock to lock the shed.
The Keter Factor line of sheds comes in a wide range of sizes. The 6ft by 6ft one we review is plenty large enough for garden tools and kids’ toys, as well as garden furniture all stacked up. The front-opening double doors give you full access to all of the inside so you can carefully place everything in the most efficient arrangement to use all the storage space to its best advantage. (Think Tetris.) The high-quality materials and construction of this Keter Factor shed (with just a little care from you) ensure that it lasts for years.

4. Keter Store It Out Max
The Keter Store It Out Max more of an extra-large storage cupboard that a traditional shed. However as it meets the needs of most gardeners, and the fact that we also have one in our garden, it’s made it onto our list. Keter makes many styles of sheds in various sizes but the Keter Store It Out Max is one of the most popular and best-reviewed sheds on Amazon.
Keter is one of the best and most trusted manufactures of plastic sheds in the world. This shed is made from their signature strong polypropylene resin plastic, which makes it fade resistant as well as very strong and long-lasting.
This shed/storage box has a large 1200-litre capacity. This makes it ideal for storing most garden items including lawnmowers, garden tools, chairs and anything else you can think of that needs to be tucked away when not in use. To give you a better idea of the size, it will hold two large 240-litre wheelie bins.
Notable features of this shed include two front opening doors and a piston operated lifting lid for easy access. Your garden equipment is secure with a lockable bolt and padlock facility. Quite a few online reviewers report that parts of their unit were damaged when they received this shed. Be aware that this model may not travel well.
If this storage cupboard seems familiar, you may have noticed it at a caravan park, as it’s widely used for extra storage at such venues.
- Storage cupboard/shed made out of durable polypropylene resin is less visible than a traditional shed.
- Two front opening doors and a full-width lid give you access to the entire storage space at once so you can see everything that’s inside at the same time.
- Easy to open as the lid is piston operated.
- Large 1200-litre capacity can hold garden equipment the size of two 240-litre wheelie bins (or your two garbage wheelie bins themselves).
- Built-in shelf support for any shelves you might already have.
- (external) 146cm (length); 82cm; (width) and 126cm (height)
- (internal) 132cm (length); 76cm (width); and 110 cm (height)
- Panels arrived damaged in transit.

5. Keter 4ft x 6ft Factor Shed
Keter Factor Outdoor Plastic Garden Storage Shed is another in the Factor range of sheds. But this one, at 4ft by 6ft, is slightly smaller than the 8ft by 6ft one we reviewed earlier. But everything else remains the same.
This traditional shed is made from durable polypropylene resin that is UV stabilised, which basically means it will not fade. The colour fading is a common problem with some cheaper brands of plastic sheds. The Factor shed has a steel-reinforced frame for extra strength. The skylight and side window lets in plenty of light, a feature most sheds simply do not have.
This Keter model, like all of them, comes with a strong hard-wearing floor and can be locked with a padlock for security.
Keter provides a 10-year manufacturer’s limited warranty for peace of mind.
- Keter’s usual high-quality construction and materials create a long-lasting and easy to maintain plastic shed.
- Front double doors open up the entire storage space to easily roll large equipment in.
- The structure is steel reinforced to keep unwanted visitors out and your stuff safely in.
- Skylight and a single shatterproof window let some light into the dark inside so you can easily see in there.
- Shelf supports are built-in for you to put up your own shelves according to your organisation plan.
- The vent lets air flow around to prevent odours and mould.
- A heavy-duty floor panel gives your items somewhere clean and dry to stand on.
- (external) 189cm (length); 129m (width); and 216cm (height);
- (internal): 172cm (length); 112cm (width); and 209cm (height)
- Have to provide your own padlock to make the shed secure.

6. Palram 6 x 8ft Skylight Amber Plastic Shed
Looking like a log cabin, the Palram Skylight Amber Plastic Shed has some unique features you often don’t find on other plastic sheds. Plus Palram is one of the best makers of sheds on the market.
We review the 6ft by 8ft shed. This amount of storage is enough for those who have lots of tools to store, from garden lawnmower and strimmers to power tools, and also the patio set. Other sizes of sheds range from 4ft by 6ft to 6ft by 12ft.
Palram sheds are made from strong polycarbonate panels which are virtually unbreakable. For added strength, they have aluminium and galvanised steel frame. However, some online reviewers state that the panels are a little thinner than they anticipated.
Notice there are no windows on this model. This reduces the risk of people breaking in through any windows. But our first thoughts are that it’s going to be dark inside, which is a big negative.
Well, the smart designers at Palram have thought of that and have fitted this shed with a tinted light-transmitting roof. This clever design lets plenty of light into the shed, so you have no problem finding your tools and other stuff. You have enough light to see enough everything, all without compromising strength and security.
Finally, the shed has a non-slip floor and ramp. This is great as you can push a wheelbarrow or the lawnmower into the shed with ease, with no awkward lifting to get it through the door. Finally, as you would expect, the doors can be locked with a padlock for security.
- Premium shed with unique features for additional security so your stored items are extra safe.
- Polycarbonate panels are durable, extra strong and almost unbreakable.
- The frame is aluminium and galvanised steel for extra strength and security.
- A windowless structure so no-one can break in that way.
- A tinted light-transmitted roof lets natural light into the shed so you can see your stuff when you’re inside.
- Non-slip floor so nothing slides about as you rearrange your garden paraphernalia.
- Ramp lets you easily wheel your heavy garden machinery inside.
- Ten-year warranty so your items are safe for a long time.
- Panels are a little thinner than expected.
Don’t let its log cabin look deceive you. The Palram Skylight Amber Plastic Shed is a structure whose designers have taken great pains to ensure has the utmost in security features. The polycarbonate panels are extra strong and you can’t break in through the windows as there aren’t any. Natural light comes in through the roof. The frame is aluminium and galvanised steel so it’s difficult to twist out of the way. But it’s easy to put all your possessions into the shed by using the ramp.
The Palram Skylight Amber Plastic Shed is a good choice if the security of your garden equipment is always on your mind.

7. Duramax 10ft X 8ft Premier Series Shed
If you need lots of garden storage space and you have the room, the Duramax 10ft X 8ft Premier Series Shed fits the bill. This polyvinyl shed boasts an impressive 481 cubic feet of storage room with tall and wide double doors so you don’t need to worry about having to twist and push your oversize items inside it.
The shed’s fire-retardant panels are both strong and durable. Add in the reinforced steel frame and the roof truss support, and you’ve got a structure that can withstand the heavy strain you may put on it with the equipment you store. However, this model comes without a base. There’s a foundation package but there are no details on either the sales website or the manufacturer’s site as to what this is. Online reviewers confirm that you do have to supply plywood or concrete to put this shed on.
The double doors at the front open for easy access to the interior and the three windows, two in the front and one on the right side let light in. You need to provide your own padlock to lock this shed up.
- Large polyvinyl panels are supported by a steel structure for strength and longevity.
- Double doors are wide and tall to let strangely shaped objects through.
- Three windows let natural light into the dark interior so you can find things easily.
- Storage space is an impressive 481 cubic feet.
- Comes without a base.
- Comes without a padlock.
The Duramax 10ft X 8ft Premier Series Shed is one of the larger sheds in our review. It’s a solid shed that can hold pretty much all your garden and patio equipment, tools and furniture in its 481 cubic feet of space. The tall and wide doors give you the facility to take awkward and oversize items through the doorway, though stacking them up efficiently may be another matter. This is a worthy consideration for those who have mounds of outdoors stuff to hide away, although you do need to provide the base it stands on.

Buying a plastic garden shed doesn’t involve many decisions. You’ve already made the main one by choosing plastic over metal or wood. Here are the other decisions you need to make.
The size of the best shed for you depends on just a few considerations and some honest appraisal.
How much space do you have?
Be realistic about this. Although you may the room for a large shed, do you want it to be the focal point of your outdoor space? If you want your shed tucked out of the way, how much room do you really have behind the garage? Are you prepared to remove a few bushes or trees to make the room that you need?
Also consider how much room you need to fully open the doors. And what about the space requirements in front of the door for you to roll your lawnmower into the shed?
What do you want to use the shed for?
If all or part of the shed is to be a workspace, you obviously need to look for a model on the larger side. Storage is easier to work out the shed size for, as long as you’re honest about how much garden equipment, kids’ garden toys and patio furniture you want to store in there. And don’t forget your ability (or not) to stack things up, Tetris-like, so not to leave unused gaps.
We came across many online reviewers who were surprised that the size of the shed they received was smaller than what they expected. We think that this may have sometimes been because they went with the measurements in the shed’s name. These measurements are usually the external or outside measurements, the shed’s footprint, and not the measurements inside the shed.
In our review, we’ve done our best to identify the internal/inside measurements where they were available. This is how much actual storage space you have inside the shed. These are the measurements to go by.
It’s one thing to have a large shed but another to find out that the door is too small or in the wrong place to get oversize or awkward shape items through the doorway. Look for sheds that have double doors and even taller than usual doors, especially if you have large or wide items to put away.
A ramp is also useful to wheel lawn mowers or wheelbarrows easily up.
All but one of the garden sheds in our review comes with their own built-in base. If you have your own base ready, perhaps a raised wooded deck or a concrete pad, then you can look for a shed without a base. If you don’t, then be aware that a shed without an included base will cost you extra for the plywood or concrete blocks to provide it with flooring. make sure that, whatever base you use, you have very level ground to put it on.
Colour and style
The good news is that plastic garden sheds are weatherproof, rustproof, rotproof and extremely low maintenance. They don’t need painting or treating and you just need to wash them down occasionally to remove the dust and grime. The downside of this is that you can’t change their colour, so you have to take the usually neutral browns and beiges that they come in. Most plastic garden sheds definitely put function over style, but some more visually attractive ones can be found.

You want your stored items to be snug and safe in your garden shed. At the very least, any doors in the plastic shed should have padlock bars for you to put your own padlock through to secure the door. Some sheds come with their own locking system. One of the models in our review, the Palram Skylight Amber Plastic Shed, is designed with security considerations foremost in mind.
What are the advantages of a plastic shed over any other material?
What makes plastic sheds appealing to many people is they are literally maintenance-free as they require no painting. Plastic shed panels are often made from strong polypropylene resin which is robust, yet flexible and fade-resistant to keep it looking good for many years. Some manufacturers even give 10-year guarantees with their sheds.
Plastic sheds are weatherproof, rustproof and rotproof. As long as the vents (usually on the gables) are open, the air flow helps to prevent the build up of nasty smells and mould inside. As the plastic panels are moulded, they can be made to any size so you find a wide range of shed sizes. You can buy a plastic garden shed as small as 4ft by 3ft up to 12ft by 24ft and even larger.
Are plastic sheds waterproof?
Yes, but only to an extent.
Plastic itself is a waterproof material so rain won’t come through the sides of your shed. The roof of most sheds are slanted up to a point so the rain will run down and off them, so you’re OK there.
However, as with any structure, rain will find its way in through any crevice, crack or opening. Make sure you put the shed together with great attention to the joins. Seal up any opening, however small, that you find. And go into the shed during a rainstorm and visually check all the walls, the roof and the floor for any leaks.
Stopping your garden and other outdoor spaces from becoming cluttered with equipment, tools, toys and unused furniture is much easier when you have a shed to store everything in. Plastic sheds are exceedingly low maintenance (just wash them down occasionally) and are weatherproof, strong and long-lasting. They come in a full range of sizes to suit both your available space and the amount of stuff you have. Some of them are visually appealing and can add to your garden decor while others are more unobtrusive and won’t stand out.
The Keter Scala Outdoor Plastic Garden Storage Shed is our selection for Best Plastic Storage Shed. This model, at 6ft by 5ft, is a good size for the average garden and its double doors, with windows, let you fully access the interior.
Our Runner-up choice is the Lifetime 15ft. W x 8ft. D Apex Plastic Shed. This is the largest shed we review and looks like a small cottage or playhouse. Its roof is supported by steel tresses for extra strength and stability.
If your choice of plastic shed doesn’t come with a base, our Best Shed Base article has some excellent recommendations. And if you only need a small shed for odds and ends, check out our Best Small Sheds article for some great options.
