The best tiles for a small bathroom (and the myths to ignore)
6 min read · Updated 15 July 2026
The short answer
Use large-format tiles (600x600mm or bigger) with a colour-matched grout and run the same floor tile into the shower. Fewer, quieter grout lines read as more space. Small mosaic everywhere is the single most common mistake in a small bathroom.
Big tiles in a small room: the myth, corrected
The old advice was small room, small tile. It is wrong. What makes a room feel cramped is visual noise, and grout lines are visual noise. A 600x600mm floor in a 2x2m bathroom gives you nine tiles and a calm floor; a 100mm mosaic gives you four hundred and a grid.
The practical limit is cutting, not looks. In a very small room a huge tile means most pieces are cuts, so you pay more in waste. 600x600mm or 600x1200mm is usually the sweet spot.
Grout colour matters more than tile colour
Match the grout to the tile and the surface reads as one plane. Contrast the grout and you draw a grid that measures the room for the eye and makes it feel smaller. If you love the contrast look, use it on one wall only — behind the basin or inside the shower niche — and keep everything else quiet.
One exception: on a floor, pure white grout is a maintenance trap. Go a half-shade darker than the tile and you will never notice the difference, but you will notice the cleaning.
Run the floor into the shower
A shower tray in a different material creates a hard visual break that chops the floor in two. Tiling the floor continuously into a level-access shower with a linear drain removes the break entirely and is the single biggest perceived-space win available in a small bathroom.
It requires proper tanking and a formed fall of around 1:60 to the drain, so it is a specialist job — but it also removes the step, which future-proofs the room.
Vertical, horizontal and where to use each
Vertical stack bond or a tall metro layout draws the eye up and adds perceived ceiling height — good in a low-ceilinged flat. Horizontal brick bond stretches the room sideways — good in a narrow shower room. Herringbone adds movement and works best as a feature panel rather than wall to wall in a tight space.
Finishes that punish small bathrooms
High-gloss dark tiles show every water spot and every fingerprint, and a small bathroom gets both constantly. Heavily textured stone-effect tiles trap soap scum. Very matt light tiles in a shower can be slippery when wet — check for R10 or better on any floor tile that gets showered on.
