fitting a raised shower tray....

[benny80]

Hi
In the process of fitting a new 760mm square shower tray in the exisiting shower enclosure in an en suite ( 3 sides are existing walls with a gap for the door). the old tray was raised on 2 x 4's laid flat to allow for the shower trap/waste to drain away. is this a common way of fitting trays? the plan is to fit the new one in the same way. One concern is getting the tray level. the other concern is that the gap between two side walls in 740mm not 760mm so to compensate the plaster board wall doesn't descend all the way to the floor but stops approx 5-8cm above the top of the tray - i would imagine this would have to be patched in order for the tiler to come in and do his thing by tiling to the top lip of the tray and to avoid leaks into the wall?
Cheers

Yes - if there isnt room under the tray then the normal thing to do is raise the tray up. You can build a plinth quite easily by cutting strips of 2x4 timber and sandwiching them between 18mm ply. You can then cut out you hole for your waste on the top sheet of ply, sit the tray on top and fit the shallow trap in the middle (between the 2 sheets). This then gives acess to the trap if need be in the future.

With the tray raised up will this not then butt the tray up to the plasterboard? If not you will need to make the difference up ready for tiling, i'd use this opertunity to use something more suitable like aqua panel.
