Kartell K-VIT Unity Rectangle Low Profile Shower Tray – White (All Sizes)

With 31 sizes running from 900 x 700mm all the way to 1800 x 800mm, the Kartell K-VIT Unity rectangle is the most useful tray in the range — and the one most likely to have a size that matches an awkward alcove or a bath you're replacing with a shower. At 45mm high it sits close to the floor for an almost level-access finish, rather than the 80–110mm step of an older-style tray.

What it's made of

Unity trays are moulded from acrylic-capped stone resin and double skinned. The stone resin core is what 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 that wipes clean and holds its colour rather than yellowing. Every Unity tray is made in Britain and carries Kartell's 25 year guarantee.

Choosing your size

Measure the alcove at floor level, and measure at both ends — older walls are rarely parallel, and it's the narrowest point the tray has to pass. If you're taking out a standard 1700mm bath, the 1700mm trays drop straight into the same run. The 760mm depths exist specifically to replace older imperial-sized trays, so if you're refitting rather than starting fresh it's worth checking whether 760 fits better than 800.

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. The fast flow design clears water quickly, which matters more on a low profile tray because there is less depth to hold a surge — and more again on the longer sizes, where a slow waste shows up as water pooling at one end.

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 — a Unity riser kit lifts the tray onto a 90mm plinth and hides the pipework behind a matching gloss white front panel:

• Riser kit for trays up to 1200mm (UNP1290100)
• Riser kit for 1300–1800mm trays (UNP1810100)

The legs adjust between 90 and 120mm; going above 90mm means sourcing a taller plinth. Riser kits carry a 1 year guarantee rather than the 25 years on the tray.

These are heavy. A 1600 x 700mm tray is around 34kg, so the longer sizes are a two-person lift and worth planning for on delivery day.
