Plastic Sheds with Floors

Why buy a plastic shed with floor included?

Plenty of sheds arrive as four walls and a roof. You then buy a floor kit, build a timber frame or lay a slab and hope it all lines up. A garden shed that comes complete skips that step. Its floor panel is made to fit the walls, it clips or screws into them and it lifts everything you store off the ground.

That matters more than it sounds. Here's what it actually does for your garden storage.

• It keeps damp out. Ground moisture rises through bare slabs and soil. A plastic or resin deck stops it reaching mower decks, cardboard boxes and cushions.
• It squares the shed up. The walls lock into the floor, so the frame stays true and the doors keep closing properly.
• It's easy to clean. Mud, oil and grass cuttings sweep or hose straight off. Nothing soaks in.
• It gives you grip. Palram's polycarbonate decks have an anti-slip finish, which helps when you walk in with wet boots.

The walls are just as easy to live with in any weather. Resin and polycarbonate are durable, weather resistant and low maintenance. There's no rust and no annual coat of preservative, which is why a resin shed or polycarbonate storage shed appeals to anyone tired of painting timber.

Plastic shed floors compared

Not every plastic shed floor is the same. Each brand uses its own material. That changes how much weight it takes. Here's every range we list, using the details from Shedstore's listings. Prices change often, so each range sits in a price band. The grid above always shows today's price.

Palram Canopia has the most choice, with 20 models across four ranges, nearly all in grey or dark grey. Keter has 19, all in wood-effect grey or beige resin, so if you want a resin shed that looks like painted timber, start there. Shire's two Tuscany Evo stores are the smallest here.

The ranges in more detail

Keter Factor, Newton Plus and Stronghold

Keter puts heavy-duty resin underfoot in every model we list. The Factor is where most people start. Its steel-reinforced walls have a wood-effect finish, two shelves come in the kit and the 8x8 is rated for a 75kg per square metre snow load. Two people can build one. Each comes with a 15 year warranty. See the full range on our Keter Factor sheds page.

The Newton Plus is the modular one. Its double-wall Evotech panels let you choose where the doors and windows go. It comes in 12 sizes from 7'5 x 7' up to 17' x 7'5. Long, narrow versions suit a side return, while the reverse apex models put the doors on the long side. Compare them on our Newton Plus sheds page. The Stronghold is the toughest of the three, with a steel-reinforced apex roof rated for 150kg per square metre of snow and a 3-point locking system.

Palram Canopia Rubicon and Skylight

Palram's sheds use polycarbonate on a rust-free aluminium frame. The Rubicon has thick 10mm multi-wall panels, ramped double doors and an anti-slip polycarbonate deck. It runs all the way from 6' x 8' to 8' x 20'. The deep sizes are great for a ride-on or a long run of garden tools. The Skylight is the lighter, cheaper range with thinner polycarbonate walls, from a 6' x 3' tool store to a 6' x 12'. Both let daylight in through clear roof panels, so you rarely need a light for daytime jobs. The grey 6x3 and 4x6 listings include a Hilti anchoring kit, handy on an exposed plot. More sizes are in our Palram Canopia sheds collection.

Palram Canopia Yukon with WPC floor

The Yukon is the big one, at 11ft wide and up to 21ft 3in deep. Here the deck is wood polymer composite, a waterproof board that's slip and impact resistant, sitting on a galvanised steel perimeter frame. It comes with integral guttering and a 15 year warranty. One thing to watch: Shedstore also sells the Yukon without one. Only listings with "WPC Floor" in the name include it. Those are the only Yukons on this page.

Shire Tuscany Evo

Shire's two stores are compact sheds for a patio or a narrow path, with a pent roof on the 4' x 2'6 and an apex on the 4' x 4'. Underfoot are weather resistant 45mm interlocking resin tiles in UV protected ABS, under walls of 22mm box-section recycled PVC. The 4' x 4' has double doors and two windows. Both carry a one year guarantee, much shorter than the Keter and Palram sheds.

Does a shed with a floor still need a foundation?

It does, even though most buyers hope otherwise. A built-in floor doesn't change the answer. It's the inside surface. It isn't built to bridge dips or lumps. Put it on grass or soft soil and it'll flex and sink. Once it twists, the walls go out of square and the doors stop lining up.

Lay something flat first. Any of these works:

1. A concrete pad, best for the largest sheds and for anchoring.
2. Paving slabs on compacted sand and hardcore, a good weekend job for smaller sizes.
3. A plastic grid kit filled with gravel, which drains well and needs no concrete.
4. An adjustable kit on a slope, which raises the shed level without digging.

Make the foundation the same size as the shed's footprint or a little bigger. Grey slabs or a gravel grid also keep a tidy edge round your garden storage. We compare grid kits on our shed bases page, by size in 6x4, 8x6 and 10x8 shed bases, with sloping gardens covered by adjustable shed bases. Anchor the shed down as well, especially in an exposed outdoor space. A light polycarbonate shed can lift in a strong wind if it isn't fixed.

Choosing the right plastic garden shed with floor

Size comes first, so measure the space and then check each shed's footprint, not just the name. Listings often quote the roof overhang, so the walls may sit a few centimetres inside it. Then work through the rest.

• What you'll wheel in. A barrow or lawnmower needs double doors, ideally with a low ramp like the Rubicon's.
• How heavy it is. A ride-on or a stack of paving needs a sturdy deck. The Factor's heavy-duty resin and the Yukon's WPC on steel are the strongest here.
• Light or privacy. Palram roof panels flood the inside with daylight. The Factor and Newton Plus add proper windows.
• Ventilation. The Factor has vents built in and the Skylight 4x6 has a vent front and rear. Good air flow matters because condensation is the main reason a closed shed smells damp.
• Security. All of these sheds have lockable double or single doors. The Stronghold adds a 3-point lock.

By size, browse our 6x4, 6x6, 8x6, 8x8 and 10x8 plastic sheds. A tight budget? Try cheap plastic sheds. For tougher walls, see heavy duty plastic sheds.

Large plastic sheds: the bigger sizes

Once you go past about 8 by 10ft, the floor does more work. A ride-on, a barbecue and garden furniture all sit on it at once. Every large plastic shed we list comes complete, from the 8' x 11' Factor to the 11' x 21'3 Yukon. The long Rubicon and Newton Plus sizes are worth a look if your garden is narrow but deep.

Two big sheds sit just over 2.5m at the ridge: the Stronghold at 2.51m and the Yukon at 2.52m. That's relevant to planning, covered next.

Do you need planning permission?

Usually not, as long as you stick to a few rules. In England most garden sheds count as permitted development. The key rule for a shed within 2m of a boundary is a maximum height of 2.5m. All of the Factor, Newton Plus, Rubicon, Skylight and Shire sheds come in under that, so they can go against a fence. Set the Stronghold or Yukon at least 2m back, where the limit is higher, or check with your council first. Sheds also can't go in front of the house or cover more than half the garden. The government's permitted development technical guidance has the full rules for England. Wales, Scotland and Northern Ireland have their own.

Plastic vs wooden and metal shed floors

A wooden shed usually has tongue and groove boards or OSB on bearers. It's easy to screw into, but it needs treating and the bearers can rot if they sit in water. A metal shed often has no floor at all, so you buy a kit or a timber frame for it. Metal can also dent and run with condensation. Plastic won't swell and spills wipe off. The trade-off is fixings. You can't screw a tool rack or shelves into resin like timber, so use the brackets made for each range. Ideas are on our shed shelving page. The full comparison is in our plastic vs wooden shed guide.

Plastic sheds with floors: FAQs

Do Keter sheds come with a floor?

All 19 we list include one. The Factor's is heavy-duty resin. The Newton Plus and Stronghold have a heavy-duty one in the kit. Not every model elsewhere does, so check the listing before you buy one that isn't here.

Do Palram sheds have floors?

The Rubicon, Skylight and Voyager models here all include an anti-slip floor. The Yukon is sold both ways, so pick a listing that says "with WPC Floor".

Can I put one straight on grass?

No, because the lawn will sink unevenly and the shed will twist. Lay slabs, concrete or a gravel grid first.

How much weight can a plastic shed floor take?

Makers rarely publish a figure. On a firm foundation the heavy-duty Factor, Newton Plus and Stronghold and the Yukon's WPC deck are listed for bikes, mowers and barbecues. For a heavy ride-on, choose one of those and keep the foundation solid.

Are they secure?

They're as secure as their lock. Each is a lockable garden shed, but there's nothing to lock it with in the box. Fit a closed-shackle padlock and anchor the shed down. Alarms and locks are on our shed security page.

Which of these sheds suit bikes?

The deeper Rubicon and Newton Plus sizes take several bikes in a line. For smaller outdoor storage, like cushions or a hose, a plastic garden storage box may do the job without a shed. Our plastic bike sheds page lists the ones that suit bikes best.
