    Hi

    Firstly I have spent ages searching his topic so please don’t think I am just creating another post for the hell of it.

    So I have now done my 5th bathroom (diy for myself and friends)

    I have used backer boards for the floors. All on timber floors (floorboards and t&g moisture chipboard)

    Now obviously the floor needs to be solid prior to any works. But my question is this:

    When tiling a regular size bathroom floor with solid floorboards or t&g should I use backer boards or ditra (or similar) ??? Assuming the floor is solid, no ufh and with porcelain tiles?

    Is there any advantage with either on a firm and solid timber floor?


    The first floor I completed was over 5 years ago with hardi boards from Topps. Still no issues.

    I have always used the following steps:

    -sbr
    -backer boards on to flexi adhesive and also screwed in to subfloor at recommend centres
    -Tile onto backer board again with a flexi adhesive.

    I have another job coming up and am just curious as to whether my method is still the right way to go.

    Thanks all

    Your method is fine. A decoupling membrane is a good alternative and has the advantage of less height buildup

    I will often use decoupling membrane over new wooden floor as it's faster to lay but backer board is often the tilers choice

    I would always overlay with board! Never decoupling straight on to T/G. :)
