Measure the usable room, not only the walls
Record the finished wall-to-wall dimensions, ceiling height, door and window positions, soil pipe, water points and any boxing. Photograph every wall. Small inaccuracies can decide whether a shower door opens properly or a vanity blocks circulation.
- Mark door and window swings
- Locate soil and waste routes
- Measure boxing and sloping ceilings
- Allow for tiles and wall build-up
Protect comfortable movement
Start with the clear floor area required to enter, turn and use each fitting. Avoid choosing sanitaryware from photographs alone: check the projection of the toilet and basin, the actual shower entry and the space needed for doors, drawers and cleaning.
Choose storage before finishes
Recessed niches, mirrored cabinets and a vanity can remove clutter without crowding the floor. Plan them alongside plumbing and electrics, not after tiling. One well-positioned storage zone often works better than several small accessories.
- Keep daily items near the basin
- Use wall-hung pieces where practical
- Coordinate niches with tile setting-out
- Keep access to valves and traps
Use light and finishes to create calm
A compact bathroom does not need to be entirely white. Limit the palette, repeat one metal finish and use layered lighting: practical light at the mirror, even general light and suitable task or accent lighting where appropriate. Check all electrical choices against bathroom-zone requirements with a qualified electrician.
