We have that kind of sheeting in our shower... ( If I am thinking of the same thing) its hard to clean and where the joins are and all over is not easy to clean. It kind of looks a bit tacky and dowdy after a while. Have you considered using mini orb or colourbond? Or even pressed tin for a feature. I've had a shower lined with colourbond and it looked really smart and was so easy to clean. It was a quick easy way to update the shower. It was even curved around the corner for a seamless finish.

I work in tiles and the normal splashback height is 600 mm. This is because overhead cupboards are usually this height above the bench top. In your case you don't have this so can do anything you like. If you tile to low 200mm etc the wall gets damaged - paint doesn't wear like tiles. There are many materials you can use as a splash back but most aren't durable eg Perspex. Glass and tiles have the edge. Textured splashes are in hence the hand made tiles. If grout annoys you use large tiles you can get them up to 1200mm long these days with rectified edges you only have 1.5mm gap. Use sealer on the grout, they are now easy clean. If you have the money tile to the bulkhead a much more luxurious look. Maybe in a charcoal. I don't know how these gaps are getting so dirty. I use spray and wipe with a toothbrush occasionally and it takes little time and always clean.

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
