AKW TriForm Wet Floor Former (All Sizes & Gulley Waste Kits)
The AKW TriForm is the designer's choice of wet floor former — combining a discreet linear gulley waste with hand-laid GRP strength for high-flow, luxury domestic wet rooms. Where standard formers drain through a single point waste, TriForm's integral linear trough can run up to 3 waste outlets for drainage of up to 78 litres per minute, making it the perfect partner for today's high-output mixer and drencher showers. Select your former size and gulley waste kit below.
Which Gulley Waste Kit Do I Need?
- Reversible Tile/Solid Stainless-Steel Kit — a two-way cover: lay tiles into the tray for a seamless “invisible” floor finish, or flip it over for a solid brushed stainless-steel strip. Choose 21213 for tiles 6–16mm thick or 21214 for tiles 16–25mm thick.
- Slotted Stainless-Steel Kit — a classic slotted brushed stainless-steel grate for a contemporary architectural look. Choose 21215 for tiles 6–16mm thick or 21216 for tiles 16–25mm thick.
- Former Only — already have your gulley kit, or replacing an existing former? Order the tray alone.
Tip: measure your tile thickness including adhesive bed before choosing — the 6–16mm kits suit most standard porcelain and ceramic tiles; the 16–25mm kits suit thick porcelain, stone and slate.
Only need a replacement or spare cover? See our AKW TriForm Gulley Waste Kits (All Options) listing. Prefer everything in one box? The AKW TriForm with Reversible Drain & Waste (All Sizes) comes complete with the drain assembly and waste included.
Key Features:
- Exceptional drainage: 4 pre-formed gradient planes and up to 3 linear waste holes deliver up to 78 L/min — ideal for high-flow mixer shower installations.
- Integral waterproof trough: the linear trough with 3 waste positions provides excellent waterproofing without relying on silicone.
- Hand-laid GRP strength: 22mm thick moulded construction supports up to 40 stone (254kg).
- Trim to fit: easily cut to within 100mm of the waste for awkward spaces and alcoves.
- Tile-ready: pre-keyed surface saves preparation time; accommodates tiles up to 25mm thick.
- Compatible with a range of AKW gravity and pumped wastes.
- Lifetime warranty on the former; 5-year warranty on gulley waste kits. UKCA & CE approved.
