How we score. The value score is our own sum from the listed specs and Shedstore's price. It is not a customer review and we have not tested the products. For a shed: 45% is price per square foot against other sheds, 25% is guarantee length, 20% is features (floor, windows, lock, double doors) and 10% is any saving off the RRP. Bases are scored on price per square foot and guarantee, storage boxes on price per litre, guarantee and lock. Give us your space and it becomes a match score that also rewards the products that make best use of it.
These Keter Factor sheds are the four sizes of Keter's wood-effect resin apex shed sold by Shedstore: 6x6, 8x6, 8x8 and 8x11. Each one has steel-reinforced resin walls, a heavy duty floor, a window, a skylight, two shelves and a 15 year warranty, so the only real choice is how much room you need.
They suit anyone who wants the look of a beige timber shed with brown doors but never wants to paint or treat it again. For the rest of the brand, see all our Keter sheds, or compare other makes on our resin sheds page.
Factor is Keter's mid-range apex garden shed. Keter is an Israeli company that has made plastic goods since 1948, and this line is its answer to people who like the look of a wooden shed but not the upkeep. The walls are resin panels with a wood-effect texture, reinforced inside with steel, and the roof is a gable apex with a clear skylight panel. Every model comes in the same two-tone finish: beige walls with brown double doors.
The range is built to cope with British weather. The resin won't rot, rust, peel or dent, it's UV protected so the colour doesn't fade, and there's no maintenance: nothing to paint, varnish or re-felt. Keter rates the roof for a snow load of 75kg/m², which is fine for most of the UK. If you live somewhere that gets deep snow every winter, brush it off the roof after heavy falls.
The four models share the same panels and doors, so the table below is the quickest way to see what you get for the extra money. Sizes are the maker's own figures, rounded to the nearest centimetre. External size is width by depth; the last size column is the minimum foundation Keter asks for. Prices change often, so we show a rough band and the grid above shows today's price at Shedstore.
| Model | External | Internal | Height | Capacity | Weight | Min. foundation | Price band |
|---|---|---|---|---|---|---|---|
| 6x6 | 1.78 x 1.96m | 1.62 x 1.82m | 2.08m | 6.2m³ (220 cu ft) | 78kg | 1.74 x 1.95m | Around £800 |
| 8x6 | 2.57 x 1.82m | 2.37 x 1.62m | 2.43m | 8.1m³ (285 cu ft) | 111kg | 2.48 x 1.78m | Around £900 |
| 8x8 | 2.57 x 2.55m | 2.37 x 2.37m | 2.43m | 11.8m³ | 144kg | 2.48 x 2.55m | Around £1,100 |
| 8x11 | 2.57 x 3.32m | 2.37 x 3.12m | 2.43m | 15.5m³ | 180kg | 2.48 x 3.26m | Around £1,400 |
A few things stand out. The 8ft models all share the same 2.37m inside width, 2.39m headroom and a double door opening about 1.38m wide, so the only change between them is depth. The 6x6 is the odd one out: it's shorter at 2.08m, which suits a low fence line or a spot under a tree.
The 6x6 is the smallest and lightest model at about 78kg, with an inside floor of 1.62 by 1.82m. That's room for a push mower, a strimmer, long-handled garden tools and the folding chairs, with the two shelves taking pots, paint and the DIY kit. If you're short of space and want to compare other makes the same size, see our 6x6 plastic sheds.
More people search for the 8x6 than any other size, and it's easy to see why. It's 8ft wide across the front and 6ft deep, so it fits along the back of a typical garden without eating the lawn. Inside you get 2.37 by 1.62m and almost 2.4m of headroom, enough for a mower, two bicycles against the side wall and the barbecue. Owners' reviews say two people can build it in about five hours. For other sheds this size, see our 8x6 plastic sheds.
The 8x8 is a square shed with 11.8 cubic metres inside, which is plenty for bikes, a mower, garden furniture cushions and a small workbench. The 8x11 adds another metre of depth for 15.5 cubic metres, enough for bulky kit like a large mower plus several bikes. Both have the same door, window and skylight as the 8x6. They're heavy kits at 144kg and 180kg, so plan for two people on delivery day. To weigh them against other big sheds, see our 8x8 plastic sheds and large plastic sheds.
Measure the space and check it against the external and internal dimensions in the table, not just the name. Leave about 60cm round the sides so you can reach the panels during assembly.
If in doubt, go one size up. Shelving and a bike rack fill floor space fast, and a shed you can walk into is much easier to use.
Keter says a foundation is required for every model. The heavy duty floor is the inside surface, not a base, and on soft ground it will sink and twist the frame until the doors stop closing. A level concrete pad, paving slabs on compacted hardcore, or a plastic grid base filled with gravel all work. Make the foundation at least the minimum size in the table. Kits are on our shed bases page, including 8x6 shed base kits and large shed base kits for the 8x8 (the 8x11 needs a base at least 3.26m long). On a slope, use one of our adjustable shed bases.
Assembly needs no cutting or sawing. The floor sections clip together, the wall panels slot in with steel strips between them, then the roof and doors go on. All you need is an electric screwdriver and a second person. Read the instructions before you start; reviewers who skipped them had to undo whole walls. Assembly videos are on Keter's UK sheds page.
The doors have a lockable handle, but the lock isn't in the box, and reviewers found the handle itself on the flimsy side. Fit a good closed-shackle padlock and, for bikes, a ground anchor. See our shed security page. The two included shelves are best for light things like pots and spray bottles. For heavy tins and power tools add a free-standing unit from our shed shelving range.
Any plastic shed can get condensation on cold mornings. The ventilation grills help. Keep it on a dry, raised foundation and leave a gap behind it so air can move, and don't shut wet cushions in over winter.
Usually not. In England a garden shed is normally permitted development as long as it's no taller than 2.5m within 2m of a boundary, isn't in front of the house and doesn't cover more than half the garden. With an external height of 2.08m or 2.43m, every model fits under that limit, so it can go right next to the fence. Listed buildings and some protected areas have tighter rules. The details are in the government's permitted development technical guidance; Wales, Scotland and Northern Ireland have their own.
Keter makes several ranges. The Keter Newton Plus is a grey shed in many more sizes, from 7 x 7'5 up to 17ft long, with door-on-the-side reverse apex versions. The Keter Stronghold is a bigger 10ft-wide grey shed with Evotech resin walls and a steel-reinforced roof, for when even the 8x11 is too small. Palram's polycarbonate sheds have a lighter frame and a bright translucent roof; see our Palram sheds. Against a wooden shed, this range costs more than a basic timber shed of the same size, but it never needs treating, and the warranty is far longer than most timber sheds get. Read our plastic vs wooden shed guide for the full picture.
Yes, for low-maintenance garden storage. Owners like the solid floor, the light from the skylight and how smart it looks. The weak points are the lock, which you should replace with a padlock, and the two shelves, which are for light items only.
Yes. Every model includes a heavy duty resin floor panel. You still need a flat, level foundation under it.
Plan on about five hours for two people on the 8x6, a little less for the 6x6 and most of a day for the 8x11. Lay the foundation before the shed arrives.
The internal dimensions are 2.37m wide, 1.62m deep and 2.39m high, with a capacity of 285 cubic feet.
Yes, the resin panels and roof keep the rain out when the shed is built on a level foundation. Water gets in when the ground is uneven and the panels don't seal, so get the foundation right.
Keter gives a 15 year warranty on the whole range. Register it on Keter's site after you buy.
