Hi, they look like Little Diamond tiles from the Dwell collection by Heath Ceramics based in San Francisco. I know because I saw a picture of them and loved them and hunted them down! I even got them to quote for shipping to the UK but the cost was prohibitive for us sadly. If you're in the UK and find anything comparable, please let me know!

Thanks for everyone’s comments, good idea to go with safe tiles and keep up to date with more easily changed aspects of the bathroom! Was thinking about mixing the lighter grey or darker grey hexagon tile with a brick or chevron pattern as I think it looks really good, however struggling to decide where to put hex tiles and where to put chevron/brick. We are going to go with a straight edged shower seat which removes the need for mosaic tiles (which we weren’t keen on) but can’t decide which way round to do it! Am thinking one type of tile to the floor and shower floor, and another type of tile to the shower walls, seat and wall behind sink. Or should we tile seat the same as the floor? If going for grey/light tiles throughout, should floor be darker and walls be lighter? Should the brick/chevron tiles be roughly same size as hexagons or smaller/larger? We are definitely set on these hex tiles either white or grey - any suggestions for brick tiles to go with? Cheers Cheers

It can certainly be done. My parents bathroom was tiled all over, and when they updated it, it was re-tiled over the old. It looked great and less mess, but this was done by a professional tiler. Don’t attempt tiling yourself unless you are experienced, it will always look terrible. Same with plastering, it’s a really skilled job that takes years of practice. If you use a tiler he/she will be able to advise you.
