How to fit sheet vinyl flooring
Sheet vinyl comes in one big roll, so there are almost no joints for water to get through. That makes it brilliant for kitchens and bathrooms — but it also means one wrong cut and you're buying it again. Measure twice.
- Difficulty
- Moderate to hard
- Time
- Half a day for a small room
- People
- 2 people (it's heavy and floppy)
- Skill level
- Careful and patient
What you’ll need
- Sharp hooked-blade knife and a straight-blade knife
- Lots of spare blades — a blunt blade tears vinyl
- Metal straight edge
- Scribing tool or a set of dividers
- Cardboard or paper for a template
- Vinyl adhesive and a notched trowel, or double-sided tape for small rooms
- Hand roller and a heavy floor roller
Before you start
Make a template
For anything other than a plain rectangle, tape sheets of card together across the floor and trace the exact room shape. Cut the vinyl to the template rather than trying to trim it in place. This is the single best tip for sheet vinyl.
Let it relax
Unroll the vinyl in a warm room for at least 24 hours. It'll be much easier to handle and it'll lose its curl.
The floor must be perfect
Every crumb, screw head and ridge will show through as a lump. Sweep, vacuum, fill and smooth. Old floors should come up.
Warm room, warm vinyl
Aim for at least 18°C. Cold vinyl is stiff and cracks at the folds.
How to fit sheet vinyl flooring, step by step
Get the sheet into the room
Roll it out roughly in position with a few centimetres running up every wall. Let it settle flat for a bit.
Rough-cut the corners
At internal corners, cut down into the excess so the sheet can drop flat. At external corners, cut down from the top. Leave plenty — you can always take more off.
Trim to the walls
Press the vinyl firmly into the angle between floor and skirting, run a straight edge along it and cut with a hooked blade. Go slowly. Angle the blade very slightly so the cut edge tucks under.
Check the fit before sticking
Walk the whole perimeter. Nothing should be riding up the wall, and nothing should have a gap.
Fold back half the sheet
Fold it back on itself without creasing, so half the floor is exposed.
Spread the adhesive
Trowel it out evenly over the exposed half, only as far as you can lay before it skins over. In a small bathroom or loo, double-sided tape around the edges and across the middle may be all you need.
Lay it back down
Roll the vinyl back into the adhesive slowly, smoothing outwards from the centre as you go to push air out. Then do the other half.
Roll it properly
Go over the whole floor both ways with a heavy roller, then use a hand roller round the edges and in doorways.
Finish the edges
Silicone the perimeter in a bathroom or kitchen so water can't creep underneath. Fit a threshold strip in the doorway.

Mistakes to avoid
- Cutting to the wall in one go with no template. Cut short and there's no going back.
- Using a blunt blade, which tears rather than cuts.
- Fitting over a gritty floor — every bit of grit becomes a permanent bump.
- Creasing the sheet when you fold it back. Creases don't come out.
- Forgetting to silicone the edges in a bathroom, so water gets underneath.
- Trying to join two sheets in a wet room. If it needs a seam, it needs welding — that's a professional job.
Frequently asked questions
Do you have to glue sheet vinyl down?
In a small room you can often get away with double-sided tape round the perimeter and across doorways. Anything bigger than about 10–12m², or anywhere with wheeled traffic, should be fully stuck down.
Can you lay sheet vinyl over tiles?
Yes, if you fill the grout lines first with a smoothing compound. Otherwise the grout lines will show through as a grid within a few months.
Can you lay sheet vinyl over floorboards?
Only with a hardboard or plywood overlay. Bare boards will telegraph every joint.
How do you cut sheet vinyl round a toilet?
Make a card template of the base and transfer it. Trying to freehand it is how people end up buying vinyl twice.
Does sheet vinyl need welding?
Only where there's a seam or where the room has to be genuinely waterproof — commercial kitchens, wet rooms, healthcare. Welding needs a hot air gun and practice, so that's one to hand over to a fitter.
