What Type of Plywood for Bathroom Floor? Choosing the Right Plywood. When considering a material for subflooring in bathrooms, you not only want to consider the... Consider the Flooring. Consider what the top layer of the bathroom flooring will be since some types of plywood are... Ceramic, ...

Traditionally, exterior grade plywood has been the subfloor material of choice for many bathroom flooring projects. Plywood is made by gluing alternating layers of wood veneer. CDX plywood (¾”) in particular is used often because it has a high level of resistance to moisture and humidity.

For most purposes a 3/4in or 19nn WBP hardwood plywood will be more than sufficient. The flooring needs to be properly sealed and for a bathroom I'd siliscone all tile corners, skirtings to flooring, etc (as applicable).

Normally i would rip up the existing floor boards and lay 18mm WBP plywood. then work from there. because the finish tile would be the same height as the carpet meeting the tiles at the door threshold. If you are overlaying onto existing floorboards. Screw your boards down, then you could overlay 9mm WBP ply then your underfloor heating cable.

Finally the finished flooring is installed. The best plywood for flooring depends on multiple factors such as the type of finished flooring, the size of the joists, the joists spacing and moisture levels. In my experience as a custom home builder, traditional plywood is the best for flooring followed by CDX and then OSB.

Some experts suggest that 15/32-inch plywood should be standard if the underlying floor joists are spaced 16 inches apart or less, but slightly thicker 3/4-inch plywood should be used for joists spaced further apart.

I will go for 18mm WBP plywood and 6mm tile mate backerboard as this is recommend for floors (12mm is not recommended as I previously wanted to use) Mike said: yes that's fine provided you can afford the extra height. the ufh will raise the height by a further 5mm or so too and ensure you cover the cables/matting with slc (self levelling) prior to tiling
