I found choosing the tiles extremely difficult. We took 30x60 because it was included with the GU and we didn’t think the extra cost was really worth it. I think our wood-look floor tiles in the bathroom would look better in 120x30. But it was too expensive for us. My husband had seen very large-format tiles with small decorations for the hallway that he really liked; they looked somewhat like Tuscany somehow. We had it calculated. It would have cost 1200€ more for that one room, and it wasn’t worth it to him.
In the end, I was glad that we had something. Just the selection at the GU, the many many walls full of tiles and combinations. We were there several times and still overwhelmed on the day of sampling. How are you really supposed to imagine how it will look later in your own bathroom? We roughly told them what we wanted and moved around our mosaic tile as decoration. We knew we wanted that as decoration and had the sampler advise us on the surroundings. There were still dozens of tiles that would have matched, and eventually we just picked one of them. I’m very happy with it. If I had brought even larger formats into the mix, I would have been completely overwhelmed. To me, these 30x60 tiles already look really modern. For the last 9 years, I lived in a rented house with 20x30 format or so (?) in the bathroom, and all the floors square, and hall and kitchen nicely terracotta-colored, and nowadays that just makes me sick because I can’t stand looking at it anymore.
