The Tilerite vinyl floor waste flange is a finishing fitting for a tiled floor waste — it sits over the pipe riser once the slab and waterproofing membrane are in, and gives you a height-adjustable, removable grate on top. Four SKUs cover two decisions: round or square grate, and 80mm or 100mm riser.
80mm or 100mm: match the riser, don't choose on preference
The base flange is sized to fit inside an 80mm or 100mm pipe riser — TR80SC/TR80RC for 80mm, TR100SCP/TR100RCP for 100mm. This isn't a style choice: whichever riser is already in the slab is the size you need, so measure the riser before ordering rather than guessing from the waste pipe size elsewhere in the house.
Square or round: a tiling decision, not a drainage one
Both grate shapes use the same threaded clamp ring and Cyclone-style adjustable spigot underneath, so there's no functional difference in drainage performance between TR80SC/TR100SCP (square) and TR80RC/TR100RCP (round). The choice comes down to the tile layout — a square grate sits flush with a grid of square or rectangular tiles, while a round grate reads as a deliberate fixture against most layouts rather than trying to align with grout lines.
How the clamping and height adjustment works
The flange clamps the waterproofing membrane in place with three stainless screws and a clamp ring, so the membrane seal is made at the flange, not relied on elsewhere. The grate itself sits on a threaded, height-adjustable spigot, which lets you set the grate flush with the finished tile or render height after the membrane and tiling are done, rather than having to get the riser height exactly right before the slab goes in. A construction cap is supplied to keep the riser protected and debris-free during the build before the grate goes on.
Not a cam-lock flange
If you've seen a floor waste with a lift-out cam-lock bezel elsewhere on the site, that's a different mechanism — our Floor Flange collection covers the Vinylrite and Cast Bronze cam-lock range, which uses a twist-lock bezel rather than a threaded spigot. Both do the same basic job (a serviceable, finished floor waste cover); the Tilerite's threaded spigot is simpler to adjust for height during install, while a cam-lock bezel is quicker to lift out for cleaning once it's in service. Pick based on which trait matters more for the job.
Frequently Asked Questions
How do I know whether I need the 80mm or 100mm Tilerite flange?
Measure the pipe riser already in the slab — the flange base fits inside either an 80mm or 100mm riser, so the riser size decides the SKU, not the waste pipe size elsewhere in the house.
What's the difference between the square and round grate?
Purely cosmetic. Both use the same clamp ring and adjustable spigot underneath; square suits a grid tile layout, round is a more deliberate-looking fixture against most other layouts.
Is the Tilerite flange a cam-lock style grate?
No — it uses a threaded, height-adjustable spigot rather than a twist-lock cam bezel. Our Floor Flange collection covers the cam-lock Vinylrite and Cast Bronze range if that's the mechanism you're after.
Does the flange handle the waterproofing membrane itself?
The membrane is clamped at the flange using three stainless screws and a clamp ring, so the seal is made there rather than relying on a separate membrane detail elsewhere.
