Kartell K-VIT Unity Quadrant Anti-Slip Shower Tray – White (All Sizes)

A quadrant tray has a curved front edge that sweeps between two walls, so it tucks into a corner without sharp corners jutting into the room. This is the Kartell K-VIT Unity anti-slip version — the same British-made stone resin tray as the standard Unity quadrant, but with a textured surface moulded into the tray floor giving it a Class C slip rating to DIN 51097, the highest of the three barefoot-wet classifications. Like the standard range it sits just 45mm off the floor, so you get the safer surface without giving up the low, near level-access step.

Who it's for

Class C matters most where a fall would be serious or the shower gets heavy use: bathrooms adapted for an elderly or less mobile user, wet rooms in care and supported housing, holiday lets and student accommodation, gyms and clubhouses. The curved front is a particular help in a small adapted bathroom, where the extra floor space in front of the shower can be the difference between manageable and awkward.

The surface is textured rather than coated, so it can't wear off or peel the way an applied anti-slip finish eventually does. It does hold onto soap scum a little more than a smooth tray, so give it a regular wipe with a non-abrasive cleaner.

What it's made of

Moulded from acrylic-capped stone resin and double skinned. The stone resin core gives the tray its rigidity — it won't creak or flex underfoot the way a thin acrylic tray can — while the ABS acrylic cap gives a hard, non-porous surface. Made in Britain and covered by Kartell's 25 year guarantee.

Choosing your size

The measurements below are the two straight sides that meet the walls, not the width of the curve, so measure your corner along the walls at floor level. 800mm is the practical minimum for a comfortable shower, 900mm is the size most people settle on, and 1000mm gives plenty of elbow room.

If your two walls aren't equal, you want an offset quadrant instead — same curved front, one side longer than the other. Quadrant trays need a matching curved quadrant enclosure; a straight enclosure won't follow the curve.

You'll need a waste

Unity trays are supplied without a waste, and an ordinary shower waste will not fit — the outlet takes a 90mm fast flow waste. Add one from the dropdown above in chrome (FFW90), matt black, brushed brass or white, or choose "Without a waste" if you're reusing one.

Fitting it

On a solid floor the trap needs to sit below floor level, so the pipework usually has to be chased in. Where that isn't practical — a timber floor, an upstairs bathroom, or a concrete slab you'd rather not cut — the Unity quadrant riser kit (UNP100Q100) lifts the tray onto a 90mm plinth with a curved gloss white front panel shaped to follow the tray. The legs adjust between 90 and 120mm. Riser kits carry a 1 year guarantee rather than the 25 years on the tray.

Bear in mind that raising the tray reintroduces a step, which rather works against the point if you've chosen anti-slip for accessibility reasons. Where step-free access is the priority, it's worth the extra work to drop the waste below the floor.

Stone resin is heavy — treat these as a two-person lift.
