Hi all
I'm a DIYer and after some advice on finishing my bathroom floor. I know there are lots of threads like this but none seem to quite match my circumstances and I don't want to get this wrong by mixing up the advice.
The room is on the first floor above the (unheated) garage and is 3.9 by 2.6 metres. I'd like a waterproof floor, floor-level shower and electric underfloor heating (including in the shower area). I'll be using through-body porcelain tiles (well, the tiler will - I know my limits).
I've already removed all the old floorboards and sistered the original joists (2" by 6" at 16" centres) with identical C16 joists to try to minimise any deflection. I plan on placing solid insulation boards between the joists. The bulk of the plumbing is done.
The only thing I'm committed to is using a 1400mm x 900mm Tuff2 shower former (I've already cut a hole in the wall for the waste) but the rest is undecided.
My original plan was to lay 18mm WBP ply on the joists and then 6mm Marmox screwed through the ply to the joists. The UFH would then be laid on the Marmox and tiled over. This was when I thought I'd be using a Marmox shower former too. Since switching to the Tuff2, I'm wondering if I should membrane the entire floor having laid 22mm WBP ply over the joists.
If I opt for a membrane on the floor, could I still use Marmox on the walls and make a waterproof joint between the membrane and Marmox?
Any and all advice appreciated.
Cheers
Simon
