What size tiles are best for a small bathroom?

Larger tiles with fewer grout lines often make a small bathroom look cleaner and bigger, though small tiles suit curves and mosaics.

Should floor and wall tiles match?

They can, which creates a seamless look, but the floor tile must be suitable for floors and have grip when wet.

How many spare tiles should I order?

Ask your tiler. Allowing extra for cuts and breakages is standard, and keep a few spares for future repairs.

Tiles set the whole look of a bathroom, and they are hard to change later. A few decisions about size, colour and pattern make the difference between a bathroom that dates fast and one you still like years on.

Large or small tiles?

Large tiles mean fewer grout lines and a cleaner, calmer look, which suits a small bathroom. Small tiles, such as mosaics, follow curves and give a classic look but need more grout to keep clean.

Popular layouts

Straight stacked: a clean, modern grid.
Brick or metro bond: a classic and forgiving pattern.
Herringbone: adds texture and movement.
Vertical tiles: draw the eye upward in a low room.

Choose colours with care

Soft neutrals feel calm and bright. Deep greens, blues and terracotta add character. In a small room, using a single colour across walls and floor can make it feel larger.

Do not forget the grout

Grout colour changes the look. Matching it gives a seamless finish, while contrasting grout highlights the pattern. Ask about stain-resistant products in wet areas.

Floor tiles need grip

Floors should be rated for bathrooms and have enough grip when wet. Ask the supplier which tiles are suitable, and check that they work with underfloor heating if you have it.

Waterproofing matters more than the tile

In showers and around baths, the waterproofing behind the tile protects the house. Ask your fitter how they will waterproof and ventilate the room.

Order carefully

Buy a few extra tiles for cuts and breakages, and check that all the boxes come from the same batch so the colour matches.

Mistakes to avoid

Choosing tiles before the layout is fixed.
Using wall tiles on the floor.
Skipping waterproofing.
Forgetting to ask the tiler about the finish at corners and edges.
