Flexible Skirting Board: Curved Walls, Bay Windows & Bendy Trim
A flexible skirting board solves the problem rigid skirting cannot: following a curve. Where a wall bows, a bay window sweeps round, or a column breaks up a room, a solid board will not bend to suit, so you either fight it with tiny mitred pieces or leave a gap. A soft, bendy skirting trim wraps the curve in one clean run. This guide covers what a flexible skirting board is, where it earns its place, the sizes and finishes, and how to fit it.
What is a flexible skirting board?
A flexible skirting board is a soft PVC trim strip that finishes the joint between the floor and the wall, exactly like ordinary skirting, but it bends. Instead of a rigid length of MDF or timber, it is a pliable profile supplied on a roll, so it follows the line of the wall whether that line is straight or curved. Many come self-adhesive, so they stick straight onto a clean edge.
It is sometimes called a soft skirting strip, a bendy skirting or a flexible skirting trim. Whatever the name, the point is the same: it goes where a solid board will not.
Where a flexible skirting board wins
Rigid skirting is fine on a straight wall. The moment the wall stops being straight, a flexible board is the easier, neater answer.
- Curved walls and rounded room corners
- Bay and bow windows
- Columns, pillars and curved kitchen islands
- Rounded stair walls and curved partitions
- Retail and commercial fit-outs with sweeping shapes
On any of these, one length of flexible trim follows the shape in a single pass, instead of a row of short mitre cuts that never quite line up.
Flexible skirting for curved walls
A curved wall is the classic case. Bending a solid board to a tight radius either cracks it or leaves it standing proud in the middle. A flexible skirting board takes the curve without complaint and sits flat against it the whole way round.
Flexible skirting for bay windows
Bay windows change direction in a short space, with angled or curved returns. A flexible board carries round the bay in one run, so you avoid a cluster of fiddly joints right where the eye lands.
Flexible or rigid skirting: which do you need?
Match the board to the wall. Straight walls take rigid skirting, which is cheaper and gives a more traditional profile. Curved or awkward walls take flexible skirting, which bends to suit and saves a lot of cutting. Many rooms use both, rigid along the straight runs and flexible around the curve, matched in colour so the change is invisible.

Sizes and finishes
Flexible skirting boards come in a range of heights and lengths to suit different rooms. Our range covers:
- 28mm x 24mm, 5 metre length, self-adhesive, wood-effect
- 50mm x 25mm, 10 and 5 metre length
- 70mm x 20mm, 10 metre length
- 100mm x 25mm, 10 metre length
Finishes include plain colours and wood-effect, so you can match existing skirting or flooring. Self-adhesive versions carry their own backing, which speeds up fitting on a clean edge, and the longer 10 metre rolls mean fewer joins on a long curved run.
Expert tip: match the flexible board's height to your existing rigid skirting, not just the colour. A 100mm curve next to 100mm straight runs reads as one continuous line, whereas mixing the heights leaves a step the eye catches every time.
Why choose the taller 100mm board
The 100mm x 25mm board is the one to reach for when you want a proper, traditional skirting height rather than a slim trim. A taller board covers a larger gap between the floor and the wall, hides more of the wall base and any uneven plaster line, and gives more protection where furniture, vacuums and mops knock the bottom of the wall. In a room with rigid 100mm skirting on the straight walls, the 100mm flexible board matches that height exactly round the curves, so the run looks continuous.
How to fit a flexible skirting board
It is a quick job, and the flexibility makes tight shapes easy.
- Clean and dry the wall and floor edge so the adhesive grips.
- Measure round the full curve and cut the trim a touch long.
- On a cold day, warm the trim gently so it bends more easily into a tight radius.
- Peel the backing on self-adhesive types, or run a bead of grab adhesive on the rest.
- Press the trim onto the edge, working round the curve and keeping it tight to the floor.
- Hold or tape the ends until the adhesive sets.
Expert tip: start fixing from one end and work round the curve in one direction, smoothing as you go. Trying to press the whole length on at once traps bulges you then have to peel back.
Some of the range comes self-adhesive, which is the quickest option on a clean, dry edge. On dusty or freshly painted surfaces, back it up with a grab adhesive. Our guide on when to glue and when to screw helps you decide.
How to choose the right flexible skirting board
Work from the wall and the look. Pick the height that matches your existing skirting, the 100mm board for a traditional full height or a slimmer 28mm or 70mm trim for a subtle finish. Choose a colour or wood-effect that ties in with the floor or the rest of the skirting. And for a long curved run, go for the longer 10 metre roll so you keep joins to a minimum.
Common mistakes to avoid
Two things catch people out on curves.
The first is measuring across the opening instead of round the curve, which leaves you short. Always run the tape along the actual line the trim follows. The second is fitting to a dusty or damp edge, where self-adhesive backing will not hold. Clean and dry the edge first, and warm the trim in the cold so it hugs a tight radius rather than springing back.
One more worth knowing: on a very tight radius, ease the trim on slowly and let it take the shape rather than forcing it, since forcing a cold strip can leave it wanting to lift back off the wall once the pressure is gone.
Frequently asked questions
What is a flexible skirting board?
A soft PVC trim strip that finishes the floor-to-wall joint like normal skirting but bends, so it follows curved walls, bay windows and columns that rigid board cannot.
Can flexible skirting go round curved walls?
Yes, that is what it is made for. It bends to the curve and sits flat against the wall in one run, with no fiddly mitre joints.
Is flexible skirting good for bay windows?
Very. It carries round the angled or curved returns of a bay in a single length, so you avoid a cluster of joints in a visible spot.
Is flexible skirting board self-adhesive?
Some of the range is. Self-adhesive versions stick straight onto a clean, dry edge. Others fix with a grab adhesive.
What sizes does flexible skirting come in?
Our range covers 28mm x 24mm (5m), 50mm x 25mm (10.5m), 70mm x 20mm (10m) and 100mm x 25mm (10m), so you can match a slim trim or a full traditional height.
Does flexible skirting come on a roll?
Yes, it is supplied on a roll, which is what lets it bend and keeps long curved runs join-free.
What finishes are available?
Plain colours and wood-effect, so you can match existing skirting or flooring.
Can I use flexible and rigid skirting in the same room?
Yes, and it is common. Use rigid board on the straight walls and flexible on the curves, matched in colour and height so the join does not show.
How do I cut flexible skirting board?
With a sharp knife or scissors. It cuts far more easily than rigid board, with no saw needed.
