Bathroom Fitting

Raising a slimline low profile shower tray

Anonymous user 23/02/2024 - 3.03 PM

Having chose a low profile walk in shower my bathroom fitter now tells me he has to raise my 900mm x 1400mm stone shower tray as the waste pipe is above floor level and he cannot cut into joists(not happy),if this is my only option then I am querying how it should be installed.There are only 6 screw inserts for the feet around the edges,is this enough,does it need extra support?Do the floorboards need removing and a solid piece fitted to joists beneath tray?How is tray fixed into position? I am paying a lot of money for bathroom refurb and as I'm having shower only I want it right If the instructions with the shower tray don't mention building framework am I in any position to demand one?

Are you a tradesperson and able to answer this question?

Shower tray if built up should be made of timber usually and then ply on top to form the base. Waste cut out and access left. Tray to be sealed down to ply also. Legs are ok but I would build a base with 4x2 instead. Much stronger. Pure Plumbing Solutions

If your chap is using the correct legs for the tray and the floor is sound, and he gets it level and properly supported you should be absolutely fine. We've fitted dozens of these 'easy fit' or skirt kits over the years and only once have we had a cracked tray - a 1700 x 800 on a less than perfect floor. There are many advantages to fitting legs, not least of all is the ability to replace the shower trap should it ever fail (and they do)

Hi. Sorry to hear your having issues with install. Unfortunately it can happen and happened to me a while back, where the soil stack/branch was at floor level, so without major building works, we agreed on using a pump (AKW) I belive they do a M11 & M17. Can retail around £200-300 and do generate a low level of noise whilst in operation. This in turn may not suit everyone, but it is one option and will allow the tray to sit flush to the floor and the hep pipe or push fit pipework can run under flooring. In my opinion, if the tray needs to be jacked up, I have always made a platform, using timber and a sheet of ply- covering the area of the tray underneath for support. Hope this helps. Andy.

If there is no adequate waste run with a good 'fall', raising of the shower Base is needing. How robust are the feet? Personally I would build a framework platform constructed from 3x2 or 4x2 timber depending how much extra height was needed. This would spread the load across 2 or 3 joist. I would use 18mm moisture resistant floor board fixed on top of the joist to give a flat platform. Then I would lay the shower tray on a bed of flexible adhesive to prevent any movement. This would be more than sufficient. Hope this helps you. Thanks, anthony
