We have the typical 'Green' coloured P5 flooring throughout the house.
We're about to upgrade our bathroom floors to tiles (from carpet) and the height from these boards to the adjacent room floorings is 22mm.
My question is:
Would it be 'Good Practice' to lay 6mm Plywood for 11mm thick tiles plus an adhesive thickness of 5mm.
The tiles are mosaic type with the webbed bonding on the back.
