Bathroom floor advice

dickibobboy

Good Evening,

I'm in the process of putting back together an empty shell bathroom.

I plan to tile the bathroom floor that currently has 22mm floorboards in. I don't really like the idea of laying another thick layer of solid board on top to give a sturdy base in order to tile which will give even more of a step up into the room.

I can easily replace the boards in the room, would it be advisable and what should i replace them with in order to tile directly on?

Thanks
