Sampling tiles in the bathroom (size, arrangement, height)

Thank you very much for all the answers.

To be honest, I haven't really made up my mind yet. I just googled on internet portals. Unfortunately (due to Corona), the selection process takes place directly in the apartment and not in the tile store. Hopefully, there are enough tile samples to choose from. The advantage of selecting tiles in the apartment might be that you can better estimate how the tiles will look right away.

What I also read today is that anthracite is supposed to be quite sensitive to water spots. In addition, I am planning to tile the hallway as well, and it would probably make sense to use the same floor tiles as in the bathroom to make it look more harmonious. Anthracite-colored floor tiles in the hallway (no window) could seem a bit dark. Or do you think that wouldn’t be necessary (same tiles for hallway and bathroom) because the bathroom is a separate area?

I have now also looked at beige. Which color would fit floor tiles with beige or cream-colored wall tiles? Should the tiles in the bathroom actually be glossy or matte? I think the floor tiles absolutely should be matte. With wall tiles, I really don’t know what looks subtle but still good.

With which software do you create these pictures? Looks great and is a big help. The bathroom side is only tiled up to about 1.20 m and the special floor tiles are definitely not included, but otherwise it is already quite close. Very good :)

So that I understand correctly: floor tiles in sandstone and wall tiles in matte beige. I took a look at the tiles. They look good. Matte beige looks quite bright, like cream color.

The floor tiles are awesome because they look good and you don't immediately see dirt and grime!

Probably light grey or light beige/cream-colored, since taupe is a mixture of both....
