Shower tray support

[pford75]

We have a problematic plastic shower tray which keeps leaking. Basically, the problem is that there is insufficient support and some of the users are heavy (18st), causing the tray to flex at the joint with the wall and eventually result in leaking.

Any suggestions most welcome - we've tried raking out and re-sealing, but this always fails eventually. We really don't want to have to remove the tray since this is part of the whole shower and the room has been recently tiled.

We were thinking of somehow jacking up the shower tray from beneath, perhaps using some timber to provide extra support. Any thoughts on this course of action?

IF you can jack it up to get extra suport under it then you may as well remove it and and replace with a resin tray,correctly supported as per
instructions

The problem is that the tray is an unusual shape and part of a 'walk-in' shower enclosure...so it's not possible to change for a resin tray (although I have now decided that the remaining bathrooms will be fitted with resin or stone trays.)

I thinking of leaving the jack under the tray permanently...ie. using a jack to push up a piece of hardboard under the tray to increase the support......does this sound crazy?
