The salesman showed me floor tiles for the bathroom, toilet, hallway, kitchen, and wall tiles for the bathroom, which I liked. But they are very large:
Floor: 60 x 60 cm; thickness: 10 mm
Bathroom wall: 43 x 120 cm ; thickness: 10 mm
— Square tiles do not have the same stretching effect in an elongated hallway
— larger wall tiles, especially in showers --> fewer joints --> less problems with uneven joints
Are there also disadvantages?
The only disadvantage is the price. It is very expensive compared to our little ones
The tiles are not particularly large. 60x60 is almost normal.
We are just getting 120x120 cm for the floor and walls. I don't see the disadvantage of larger sizes, the fewer joints, the better.
One "minus": you have to think more about the laying scheme.
It looks funny if the wall and floor joints are straight apart. It's best to intentionally place the joints farther apart if the formats are different.
Other than that, I think you get used to everything. It also depends a little bit on the room plan, which tile formats fit well.
