Tiling Over Tiles

[j0nb0y]

I am renovating my bathroom, it is fully tiled on the walls, the tiles are firmly stuck and quite level. Is it ever a good idea to tile over the existing tiles? It would save a lot of time and effort than removing them and having to get the walls re skimmed. But, I don’t want to do a botch job. Any replies, greatly appreciated

My brilliant and expert tiler in the UK always reckoned if they are as you say it's the best way to do it, JOnbOy. He did it in two of my rooms and the result was great.
We have just had a bathroom renovated here in Ireland. All the tiles had to come off unfortunately. The mess and what was found underneath needed lots of extra and expensive work.
Builder who is an expert, I'm not, will hopefully see this and give his opinion.

A lot of stuff online says it’s fine as long as you prep the existing tiles. Hopefully builder will agree with you, then I can crack on with it. Thanks for replying

Works well as long as existing tiles are well cemented … a good flat surface to start with. Try not to lines up new joints/ seams with existing. Good luck …

You do end up with a smaller room though.

There’s a product called bluegrit

You (or your builder) need to to think about junctions with other finishes / architraves / skirtings / windows / light switches.

Cheers for all your answers. I will prep the walls correctly first, seems its quite a common thing. Will probably go with that blue grit as well Zac.

I'm afraid I was in the pub when you posted last night jonboy :o)

Anyway... yes, over-tiling is fine, but I must repeat what others have said: make sure the old tiles are pretty solid. It's easy to tell.

You will get a double-thickness edge at the top of the tiling of course.
I always use loads of "tile edging/tile trims". It makes a good "frame" around the tiling.
