In very good condition there is one small squeek in the floor between the shower and the toilet that i want to eliminate with the extra cement board.

Backer board over sheet vinyl.

The floor is now smooth. First i was told to remove the existing linoleum. I would avoid doing this if i were you. Second the strength of wood boards isn t always consistent.

The tile used on this. The biggest danger in doing a tile installation over vct or sheet vinyl flooring is not knowing what s under that flooring. Another option to backer board on wood floors is one of the new polyethylene membranes such as schluter ditra. If thickness is an issue however 1 4 inch thick backer board can be safely installed.

When tiling over existing vinyl flooring on a plywood subfloor it s not necessary remove the vinyl flooring as long as you apply a layer of cement backer board first to provide a stable surface for the tile. Then put down mortar with a 1 4 tool onto the ply floor boards. First changes in humidity make solid wood shrink swell and cup more than plywood.

Here is my concern. The second problem with tiling over vinyl is the underlayments used for vinyl installation. The same is also true for sheet vinyl. 1 4 luan plywood is common for use underneath vinyl flooring.
