What shape of wall tiles to use for the narrow and long bathroom

The floor tiles are not good for sticking to the wall, and there is a risk of falling off after a long time. There are many specifications of wall tiles on the market, 300*450, 300*600, 330*600, and even 300*900.

Use 600*600 floor tiles to process 300*600 wall tiles.

300X450 different colors of the same color, staggered vertical paste, visually have the effect of increasing the space.

Use a vertical length, but not too narrow!

It depends on what you want to do. That's what you need to do with the light in the bathroom! and the refraction of the wall tiles! and other factors such as the area of your wall.
