Best solution for a complete refit

[charlie0166]

Hi everyone, been reading all of the great advice here, and I have a question that is similar to some but I'm going to ask it anyway.
I live in a victorian house, with all of the problems that brings. We had the 1st floor bathroom done about ten years ago, but have had a series of leaks from the shower, and my wife has finally had enough. So, we are going to take the room right back to a shell, which will be joists for floor and ceiling, and a mixture of plastered brickwork and old lathe and plaster on studs for the walls.

Here's the question - with a blank canvas what's the best solution? At the moment. I'm thinking:

for the floor: additional noggins to strengthen floor joists, then 15mm WPB, overlaid with 6mm backer board, then warmup matt, and finally tiles. Shower tray will be custom made resin type to fit an alcove, with a fixed glass screen.

The shower area will be where the walls are stud work - what's the best way to prepare these walls to be tiled?

many thanks

Why not use 10mm thermal boards to give more heat on the ufh mat......

Do you mean instead of the backer board?

Yes, ontop of the ply. Try to use thicker ply if height will allow, 18/22mm.

Thanks. So, 18-22mm ply, 10mm thermal board, heating matt, tile.....
Any recommendations for thermal board?
And any suggestions for the walls?
Thanks again

Use plasterboard where the old lath and plaster is but check the timbers to make sure there all flat other wise your'll have bowed wall.....hack off the old plastering and dot and dab plasterboard onto the that and get a tanking system for the shower area.
