Ceramic floor tiles and plywood problem

[doron]

Hi

I had ceramic floor tiles fitted 4 years ago by a bathroom installer in the main bathroom.

The ceramic floor tiles are on 6mm plywood, fitted over the original chipboard flooring.

I want to fit new ceramic floor tiles now.

If I remove the tiles and adhesive, can I lay 15mm plywood over the 6mm plywood?

I was just thinking if I could save the extra work in removing the 6mm plywood.

What are my options for doing this the easiest, but the correct way?

Many thanks

6mm is far to thin, you can put 12mm on top as long as all secure which will raise the level 18mm overall.Though personally unless the ply is glued down I would remove.
