Shower tray installation

Hi it’s so much of a problem sitting your new shower tray on top of existing floor tiles as long as the drainage is accessible. The wall tiles must sit on top of the new shower tray though so these may require to be replacing

Shower trays are shaped so that water flows down the tiles, into the tray and down the drain - assuming the tiles are fitted after the tray. If you retro fit a tray on top of the tiles any water hitting the wall tiles will try and flow around the tray not into it and the water may not drain away properly. Other problems associated with retro fitting the tray as you have indicated could be - the glass shower cubicle may not fit properly - the tray may be unstable - it is meant to be fitted on a flat surface and wet room floors are not flat - how are you going to get the waste water drained? - you could end up with quite a wide strip of sealant around the tray. Not pretty. Your best option my be to rip out the wet room floor and level it so you have a stable surface for the new tray and access to drainage. If you need to cut away wall tiles to fit the new tray properly you may be able to do this with a hand held disc cutter. To save yourself a lot of heartache and probably money in the long run I suggest getting tilers / bathroom fitters in and see what they think. They may come up with other options if they see your particular issues

I'm assuming you mean that the cracked tiles are to be covered by a new shower tray, and you don't want to remove/replace the wall tiles.... Not recommend as previously mentioned, however your best bet would be to fit the new tray and use upvc wall panels over the old tiles, Just in the shower area. This will be much cheaper than re-tiling. You will also need to consider the waste for the new shower, which would now be above floor level, or by using a conversion kit to connect to the existing wetroom drain. All the best.

Hi First you need to open the waste up , take old trap out but a flex Mc alpine pipe on read for your new shower trap, make sure you leave enough room so it docent kink or bend, you want a nice flow out of new trap, connect trap and test ,now when installing the tray use a flex tile addistive , don't be shy with it make sure the area is covered in it about 30mill thick , now make sure your waste is in the right place , then you can install the tray , put plenty of clear silicone around edge of tray so it seals against your walls, now push it up tight , make sure tray is level for corner to corner , but something in the tray to weight it down and to stop any movement, leave 24 hours , then seal round edges from tray to tile, enjoy your new shower kind regard Simon Bates Designer bathrooms

Hi, I would just seal the top of the tiles and put the tray on top of it, less cost than removal.
