I work as a colourist and the easiest method for a upmarket look is to choose an exact colour to match one of the colours in the tile. I would take the tile to a paint shop and get the colourist it match exactly one of the greys in the tile. Make the depth of the colour a light version. All white walls are on the way out. Lappatto tiles usually have some texture as they are semi polished. This is the latest look in tiles as they give a shine without the maintenance of polished porcelain which had been in. They are usually less slippery than satin or polished tiles depending on the brand.

wow I love all these suggestions. I was going to suggest a grasscloth wallpaper, because it has wonderful texture. But I'm quite taken with the shelves idea now.

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

It's the floor colour that's the main problem, neither one thing nor the other, and certainly wrong with the benchtop. Leave the wall tiles if you like that sort of thing and find a way of covering the floor probably with laminate planks on an underlay. We have a European Birch golden coloured timber floor but softer grey splashback and it looks fine. It's not an award winner but the floor and cabinet carcases had been there twenty years and it was affordable. Don't even think about painting the floor or putting down mats but a clear plastic runner in front of the sink works well for us.
