Laying tiles over tiles - possible ? advisable ?

property.advert

At the end of a bath, I have about a bath's width and two tiles deep of a space which is lower than the bath and thus retains water.

Rather than rip out and replace, can I just tile over the top of the existing tiles with new ones. This would give me a much more flush appearance and appears an easier job than a full refit.

Any ideas ?

I advise people not to as a general rule. However, thoroughly degrease the tile surface, score through the glazed surface and use a quality flexible adhesive such as BAL or Ardex SPF (single part flexible). My only point to make would be this, If there is any bounce in the floor there is a very high likelihood that the new tiles will carck or debond after a relatively short time.

Good luck.

I think you are talking aboyt a "Shelf" at the end of the bath. Yes?

Common sense says remove and replace but if you don't want to to do that then perhaps a bit of bodgery might be allowable. If its the "shelf" is on a wooden frame anyway perhaps you could screw a piece of ply down first through the existing tiles into the frame and then tile over that. Prolly work for you. I'd be unhappy to recommend it as a lasting solution though.

I think the key rule is making sure you obey weight limits for the underlying substrate. 2 lots of tiles + 2 x adhesive + 2 x grout can be quite heavy, and it'll sting a bit if it lands on you in the bath.
