How to plan a small bathroom layout

1. Measure the room accurately

Measure the length and width, the height, and the position of the door, window, radiator and any pipes or boxing. Draw a simple plan on squared paper and mark everything on it.

2. List what you really need

Decide what has to be there: toilet, basin, and bath or shower. Then add the nice-to-haves, such as a second basin, a bath as well as a shower or a heated towel rail.

3. Think about where the pipes are

The toilet's waste pipe and the existing water supplies strongly affect what is practical. Keeping fittings near where they are is usually simpler than moving them. Ask a plumber before you commit to a layout that moves things.

4. Leave space to use it

• You need clear floor space in front of the toilet and basin to use them comfortably.
• Check how doors, shower doors and windows open.
• Ask your fitter or the fitting instructions for the minimum clearances for each item.

5. Choose slimmer fittings

Short-projection toilets, slim basins and a walk-in shower with a glass screen save space and look lighter than a bath with a curtain.

6. Plan storage and lighting

Recessed shelves, a mirrored cabinet and a vanity unit with drawers keep surfaces clear. Bathrooms have strict safety rules for electrical work and lights, so use a qualified electrician.

7. Ventilation and waterproofing

Good ventilation and properly waterproofed walls and floors stop damp and mould. Ask your fitter how they will deal with both.

Mistakes to avoid

• Ordering fittings before checking the measurements.
• Moving the toilet without checking the waste pipe.
• Forgetting storage and ventilation.
