Written by April Foot

Plastic sheds are a long-lasting and low-maintenance alternative to traditional wooden garden storage solutions.

There are many advantages of plastic sheds; they’re easy to install, they can be highly cost-effective, and plastic is extremely durable and hard-wearing, so it doesn’t need to be regularly treated to resist the elements, as timber sheds do.

Plastic sheds come in many different sizes and designs, so you should be able to find one that suits your garden and your needs – whether you just want a convenient place to store your lawnmower, or a stylish garden retreat in which to while away those summer days.

If you need help deciding which shed is right for you, have a look at our selection of 5 of the best plastic sheds on the market.

Best Pick: Keter 4 x 6ft Storage Shed

Our favourite plastic shed is stylish, and a good size for bikes and BBQs

Topping our list of the best plastic sheds is this 4 x 6ft Factor model from Keter. This one is made from durable, steel-reinforced plastic, and has a heavy-duty floor panel, to protect the contents.

The external dimensions of this shed are L 189 x W 129.5 x H 216.5 cm, with an internal height of 209 cm, so it’s large enough for an adult to comfortably stand up inside. The side window allows natural light into the shed, and there are ventilation grills at the top to enable air to circulate.

One of the most appealing things about this shed is the design – its made of contrasting shades of grey panels, finished in a wood effect, so it’s ideal if you want the look of a timber building, with all the practicality of plastic.

The door is designed to be easily locked if required (padlock not included), so you can enjoy the extra peace of mind that your tools will be secure – although, as it’s plastic, it wouldn’t be too difficult for a determined thief to break open, so it’s probably best not to store anything too valuable inside.

Overall, if you’re looking for a stylish plastic shed to store smaller items such as BBQs, tools and bicycles, this is the one we’d recommend.

Pros

  • Made from durable, steel-reinforced plastic.
  • Stylish wood-effect exterior.
  • Window and ventilation grills for light and air circulation.
  • High enough for an adult to comfortably stand up inside (209cm).
  • Perfect size for bicycles, tools and BBQs.
  • Easy to assemble.

Cons

  • Door could be more secure (although this is true for most plastic sheds).

Value Pick: Keter Manor Outdoor Shed

Our best value plastic shed is ideal for small spaces

Our next shed, and the one we believe offers you the best value for money, is another model by Keter – their Manor Outdoor Shed. At L 94 x W 128 x H 196 cm, this one is considerably smaller, but should still be large enough to store your BBQ and DIY or garden tool collection. The internal height is 193 cm, so the vast majority of adults will still be able to stand up inside.

The shed is made from durable, double-walled plastic panelling. Although there’s no steel-reinforcing in this one, there is a heavy-duty floor panel, to keeps the contents of your shed dry and off the ground. If you want to lock the door, it comes with a convenient padlock hasp – you just need to provide the lock.

It’s fairly easy to assemble – just make sure to lay out all the pieces first. The roof can be a bit tricky to attach, so it’s a good idea to make that first, and then attach the side panels. The shed is durable, and easy to maintain – a light washing every now and then should keep it looking as good as new.

There’s no side window on this design, so it will be dark in the shed when the door is closed – not that it’s large enough that you’ll be wanting to shut yourself in! There are ventilation ducts for air circulation though.

Other than the storage restrictions imposed by the size, there’s really not much to fault with this shed. If you’re limited on space in your garden, or you only need to store a few smaller items, this excellent value shed could be perfect for you.

Pros

  • Made from durable, weather-resistant plastic.
  • Stylish grey wood-effect exterior.
  • Space-saving – ideal for small gardens.
  • Ventilation ducts for air circulation.
  • Lockable (padlock not included).
  • Affordable.

Cons

  • No window.
  • Roof can be difficult to install.
  • Will need some form of anchoring to secure it to the ground (as with most plastic sheds).

Duramax 10 x 8ft Plastic Shed In Ivory & Brown

This large plastic shed is perfect for storing garden furniture and can double as an extra room

Moving away from grey, this 10 x 8ft design by Duramax showcases a more traditional ivory and brown finish. With external measurements of L 324.8 x W 247 x H 233.2 cm, this is also our largest shed yet, and is perfect if you have larger furniture items or lawnmowers to store.

The double doors provide easy access, ventilation holes encourage airflow, and 3 shatterproof side windows allow in plenty of natural light. All this, combined with the large floor plan of the shed, means it’s also suitable to be used as a summer house, or activity room – you could even use it to cover a hot tub.

It has a reinforced metal structure, and a roof that’s capable of holding 20lbs/sq ft of snow. The panels are made from durable, fire-retardant and weather-resistant PVC, which requires no ongoing maintenance.

If you’re concerned about security, the door handle comes with built-in holes which you can use for a padlock (not included). There’s no built-in floor with this one, but the shed does come with a foundation kit, to help you build a suitable base for it.

Ultimately, if you want a shed which gives you all the benefits of an extra room in your home, and you don’t mind laying your own foundations, this might be the one to choose.

Pros

  • Made from durable, maintenance-free vinyl with a strong metal structure.
  • Large enough to store bigger items – double doors for easy access.
  • 3 windows provide plenty of natural light.
  • Includes foundation kit.
  • Door handle is lockable (lock not included).
  • Can also be used as summer house/ extra room.

Cons

  • No built-in floor, you will need to build your own.
  • Delivered in one, heavy box – requires at least 2 people to move.

Duramax Sidemate

A well-designed shed that will sit adjacent to the side of your home

Next up on our list of the best plastic sheds is this Duramax 4 x 8ft Sidemate Shed, which is specifically designed to fit flush against the side of a fence or building. The door is reversible, so it can be positioned on either side, offering you full flexibility.

With external measurements of L 122 x W 242 x H 187 cm and internal storage space of 4.63 cubic metres, it’s an excellent medium-sized option, that’s large enough to store bicycles and garden chairs, but still compact enough that it won’t take over your garden.

It’s made from durable vinyl, with metal columns for reinforcement, and galvanised steel framework at the base – although you will need to use the included foundation kit to build the shed a proper floor. As with the previous Duramax option, the roof can handle up to 20 lbs/sq foot of snow.

The shed is windowless, but there are ventilation holes to help keep your stuff dry and mould-free. If you want to add your own padlock for extra security, there are padlock eyes in the door handle for this purpose.

The shed represents good quality for the price, and there’s an impressive 15-year manufacturer’s warranty to cover you should you experience any issues. This is an ideal choice to make the most of a narrow space along the side of your home.

Pros

  • Sturdy vinyl walls with metal reinforcements and galvanised steel base.
  • Asymmetrical style is ideal if your shed is next to a building.
  • Reversible door with padlock eyes.
  • Includes foundation kit and ventilation system.
  • 15-year warranty.

Cons

  • No floor – requires a foundation.
  • No windows for natural light.
  • Assembly is not the easiest.

Duramax Storemate 6 x 6ft

This modern-looking plastic shed has double doors for easy access

Our final shed is another option from Duramax, who really are leaders in the field of plastic sheds. This 6 x 6ft Storemate model features a two-tonal grey colour (similar to the Keter Factor, although without the wood effect), which gives it a more modern aesthetic.

It’s made from durable, fire-retardant vinyl, and also features galvanised steel supports, along with Duramax’s strong roof trusses that can carry up to 20 lbs/sq foot of snow. There’s an included heavy-duty plastic floor which means no additional foundation is required – great news for less keen DIYers.

There’s a single shatterproof window to provide natural light, a dual ventilation system to allow air to circulate, and padlock eyes in the handle if you want to add a lock. The double doors open up to W 154 x H 180 cm, offering easy access, and with an internal height of 209 cm, you won’t need to worry about hitting your head.

This shed can be prone to leaking when it rains, but if this is a problem, it can be solved by silicone sealing the studs and window. There are also reports of the pre-drilled screw holes in the shed not lining up upon assembly. If you don’t mind making a few small modifications though, you’ll end up with a stylish and practical storage shed.

Pros

  • Made from durable PVC with galvanised steel beams.
  • Full heavy-duty floor – no foundation required.
  • Includes window and dual ventilation grills.
  • Wide and tall double doors offer easy access.
  • Light enough to move once assembled.

Cons

  • Poor assembly instructions.
  • Holes for the screws may not line up.
  • May require sealing to prevent water from getting in when it rains.

Do You Need A Base For A Plastic Shed?

Whether you require a base for your plastic shed depends on the design of the shed, and where you are putting it. Most plastic sheds come with built-in flooring, so it is not generally considered essential to building another base. However, it is possible that, if placed on an uneven lawn, your shed may start to sink over time.

It is therefore advisable to place your shed on a flat, concrete or paved surface. Alternatively, if positioning it on grass, you can lay a concrete, gravel or wooden foundation first, to ensure the surface is entirely level.

How To Build & Secure A Plastic Shed

Building and installing a plastic shed is generally a fairly simple process and usually involves slotting together the pieces, and screwing them in (use a drill to make it easier).

You should always follow the manufacturer’s instructions, and enlist the help of a friend, as the pieces can be large and awkward. Choose a non-windy, mild day, as extreme heat or cold can cause plastic shed panels to warp, making it harder to assemble.

Securing your plastic shed can be a little trickier – these sheds are lightweight, which can make them vulnerable to moving in the wind, even when filled with heavy garden furniture or tools.

You can create permanent anchors for your shed in the ground by digging holes near the corners, filling them with concrete, and inserting anchor brackets. You can then attach these to straps going over the roof of your shed, to keep it secure.

There are a variety of other bolts and anchoring methods you can use to secure your shed, depending on your set up and base material. If you will be storing expensive items in your shed, it is also a good idea to secure the door with a padlock and chain, to discourage theft.
