Shower Tray Installation - to rebate or not

[kiteboy]

Hi all AGAIN :)

Ive bought a Mira Flight shower tray and just want to know what you guys think about the installation of this tray which has two tiling upstands.

The shower enclosure we have has an adjustment of 20mm so there is a little bit of play in that

We have been told that you can rebate the upstands into the two walls very very slightly and then tile over......however the tiles for the walls are pretty thick......id say the tiles are around 10mm thick in total......thats for two tiles

Therefore this will take away from my 20mm adjustment plus the fact that there is adehsive to go on aswell

My question is really whether these upstands should be rebated or not.....its a tricky one......... dont want to install the tray and tile then to find out the enclosure doesnt fit.....that would be a complete mare

Thanks again

The up stands are designed to be recessed, any other installation would be unwise, it's the tile overlap that provides the waterproof joint.

The most critical factor is how plumb are your walls?

Put a long level on the wall in a vertical position where the enclosure will fix.

If you have more than a 5mm discrepancy you're struggling.

However, you may have +/- 10mm adjustment for the screen on the tray, which would effectively leave you with 20mm adjustment still even after the tray is fitted. Also if this is a square/rectangular tray - you'll have more tolerance than a quadrant type tray.

In this situation it's your walls that are the deciding factor.
