Medium format tiles work well in a shower or wet room because they strike a sensible balance: fewer joints than a small tile, which limits moisture getting into the grout, while still allowing a bit of pattern across the walls if you want it. Porcelain remains the material of choice for a room like this, thanks to its non-porous, low maintenance surface.
On the floor, an anti-slip finish is essential, and every tile in this collection carries a suitable rating for wet conditions. On the walls, a gloss or polished finish can make the whole space feel more open and reflective, especially in a smaller shower enclosure. Zellige, metro, and mosaic tiles are popular choices at this scale for anyone who wants more texture and character on display.
