- Looking at the 900 x 1700mm wet room shower tray. Is this compatible with Topps Tiles waterproofing kit/underfloor heating/wet room kit? I had all of the Topps Tiles kit on order but their tray is only 1500 whereas yours at 1700 would fit the room space exactly.

It should be perfectly compatible with products from them, but you need to know that most of our products are suitable with 4-14 mm thick tiles. Our wet room kits are designed perfect for 8-10 mm thick tiles.

- Why is only one of the drain covers say it's suitable for tiling? Surely the tray will always be tiled over?

One of the covers (called Pure) must be tiled in. Every tray must be tiled over, but this one special grating must be filled in with tiles. It would be completely tiled after the installation (you would only see small channels allowing the water to flow).

- Is there any issue using this on a wooden chipboard floor? (I am aware that the floor will need to be cut out and noggins and boards added between so as it is firm and level).

The tray can be installed on a timber floor. It just needs to be supported beneath entire surface. You would either need to remove the floor boards, fix battens to the sides of the joists and then mount ply in between the joists or you could just lay directly on the floor boards.

I am happy to assist in case of any further questions.

Kind regards
