Hello
I'm a DIYer so apologies if I get the terminology wrong etc
I've started work remodeling my small upstairs bathroom and I am planning to lay down tiles in the main bathroom floor area.
The existing floor is 22mm Plywood and seems to be in good condition.
My plan was / is to prep the floor as follows...
- screw fasten additional 12mm wbp Ply (single sheet)
- cement in Ditra (using P9 Mapei) uncoupling membrane (I'm using Kerdi Board so went with this)
- floor tiles on top (10mm trowel), tiles are 450x450
This will give a total new height to the floor of...
12mm (ply) + 4mm (Ditra & adhesive) + 11mm (tile and adhesive)... So 27mm total.
Now I'm thinking I might just ditch the 12mm ply that I've already purchased and just go straight to Ditra and then tile over it. Meaning a new additional height of 15mm.
What do you reckon? Would 27mm be a big step up / transition? Is the 12mm ply overkill given I've already got 22mm?
One thing to add - the upstairs in my house is built on engineered trusses (Attic Trusses) running at 600mm centres.
Any advice / pointers appreciated.
