Hi Sofia I definitely think brick lay would work better on the walls in the bathroom purely because you have a 30x30 on the floor and a 30x60 on the wall. You will find the tiles could look out of place trying to stack them. It would be a different matter if they did not share 1 or more dimension. Perhaps in the ensuite, consider doing something like this: [https://www.houzz.com.au/photos/what-architecture-beirutful-house-eclectic-patio-london-phvw-vp~14310278[(https://www.houzz.com.au/photos/what-architecture-beirutful-house-eclectic-patio-london-phvw-vp~14310278) Tile the floor and half way up the back wall with the "floor tiles", perhaps a tile or 2 above the vanity unit and then continue with the white tiles to the ceiling. You could hang your mirror so it covered about 1/4 of the "floor tile" and 3/4 of the white above the centre of the sink. In the main bathroom consider something like this: [https://www.houzz.com.au/photos/victorian-dream-bathroom-victorian-bathroom-london-phvw-vp~39122647[(https://www.houzz.com.au/photos/victorian-dream-bathroom-victorian-bathroom-london-phvw-vp~39122647) Tiling the back wall to the shower in the "floor tile" to the ceiling with the white tiles behind the loo to the ceiling. Alternatively, tiling the entire back wall with the "floor tiles". The first option may make the bathroom feel smaller if the shower takes up more than 1/3 of the back wall. Doing the two different options would give the bathrooms continuity, but also some individuality. I hope this helps. Look forward to perhaps seeing the outcome. James

Nup, a good tiling job requires a good substrate. The best tiler in the world can't make a bad substrate look clean and good. No point on spending money on new tiles and a good tiler over an inferior base. Rip it all down, start again and get it right before tiling. Best of luck, Dr Retro Of Dr Retro House Calls

Have you priced having the whole lot re waterproofed and tiled? You are already doing the hardest section, it may not be that much more to do the lot. Otherwise agree with above match to the white tiles in the rest of the bathroom. But it will always look like a repair.

Hi there, tiles on the floor of a bedroom? It sounds a bit cold underfoot unless you are having underfloor heating installed, but then perhaps you are renovating in warmer climes than where I live! I would recommend going for a matte or satin finish in the bedroom as the gloss could look a little sterile.also If you have a connecting ensuite, you wouldnt want to run the risk of slipping on the floor if you have wet feet :o
