Updated 5 Aug 2026
Tile format affects the number of joints, installation difficulty, visual proportions and final cost of a bathroom.

Choose the size only after checking the room dimensions, wall flatness, drainage details and the installer’s experience with large-format tile.

What affects the final result?
- Measure the room and calculate the layout before buying tile.
- Check the flatness of walls and floors; large formats show every deviation.
- Plan joint alignment between walls, floor, niches and sanitary fittings.
- Add a sensible cutting reserve, usually 10–15% depending on the pattern.
- Use the adhesive and grout specified for the format and substrate.
- Do not choose large tile only because it is fashionable; the room and installation conditions matter more.
Frequently asked questions
Is 60 × 120 cm tile suitable for a small bathroom?
It can be, if the walls are flat and the layout allows sensible cuts. Fewer joints can make the room look calmer, but the format needs careful planning and an experienced installer.
How much extra tile should I buy?
Plan approximately 10–15% extra for cuts, corners and future repairs. A more complex pattern or diagonal installation needs a larger reserve.
Which tile format is easiest to install?
Medium formats such as 30 × 60 cm are usually the most forgiving. Small tile takes longer because of the number of joints, while large tile demands a very flat substrate and careful handling.
