:confused: Hi I have just replaced an old shower tray with a new one, however the new one is a tad smaller (760x760x90) than the old one. Once I replaced the pipe, waste trap and had the tray in position, it became apparent there were gaps at the back and to the left of the cubicle.

My question to you is do I fill the gaps with a combination of hardwood and sealants or are there better options I could perhaps apply to help. Once I've got the gaps filled then I plan to re-tile. Any advise is welcome

Thank You

You fur out the walls and install cement board and tile. Good luck, Tom

Sorry Tom you've lost me, what do you mean by "fur out the walls"? I only took out the lower two tier of tiles so as not to impact myself with too much work. So I'll only be re-tiling them.

Badoem, Tom is telling you a good fix to your problem but you may have misunderstood because the fix is huge. You made a very significant error installing an undersized shower pan. To do the job right you need to build up the thickness of the entire wall to fill the gap. If a whole new wall is not what you can handle you could just build out for the first few inches and make a tiled ledge transitioning back to the original wall.It may look pretty funky though.

If you don't wish to remove the exixting tile to stud out the walls to take up the gap then follow Bals advice and build up the gap with wood blocking and form a tile ledge. Good luck, Tom

:) Thanks Guys for your help:)
