I would like to lay ceramic tiles in an area of about 2mx2m of my bathroom. The bathroom is on the first floor as usual and has floorboards, some of which creak slightly. The floor is currently covered in horrible cork tiling and undulates by about 5mm from the measurements I have made with a 1m spirit level. The floor does seem to be essentially level, but I suppose I should check this further.
I would rather not rip up the floorboards so presumably the job list would look something like
1) Rip up cork tiles and try and scrape as much of the old adhesive off the floorboards as possible.
2) Screw in floorboards with some 20mm screws or some such to firm them up.
3) Now at this point would it be worth trying to sand down the undulations in the floor boards to remove the 5mm undulations and if so how would be the best way to do it? Presumably one shouldn't screw in the 12mm ply recommended in the sticky thread onto an undulating floor? I would rather not use a levelling compound as I really don't want the bathroom floor any higher than is absolutely necessary. Should I aim to get 2mm or some other value of undulation before fixing ply?
4) If necessary apply some levelling compound
5) Firmly fix 12mm ply into floorboards with counter sunk screws (20mm?) ( and through boards into joists where possible?) every 150mm
6) Lay Carra Satin Marble ceramic tiles from Homebase of 10mm thickness, these are rectangular, do I have to lay these in a brick layer pattern? I know I should use an expensive flexible adhesive such as UltraProRapid PB, which a local tile shop gave me for another tile job I am doing in my kitchen where there is a concrete floor. Tile link
7) Apply a flexible top notch grout, can I use white grout to go with the tiles? Or will that discolour with age?
8 ) Attempt to make step from landing floor carpet to new bathroom floor as inconspicuous as possible with wedge shaped wood or some other fitting.
