I'm laying vinyl floor tiles in my bathroom. I'm going to lay a base of 15mm ply and then seal it with PVA. My question though, it is are these tiles likely to lift? I'm concerned that water and steam in the bathroom will get in the tiny gaps between the tiles and weaken the adhesive. I don't suppose there's any sort of grouting that could seal the gaps between the tiles? I've never heard of this on vinyl floor tiles so I'm not hopeful.
