Measure the finished room, mark the door swing and required fixture clearances, retain practical service positions, place the largest fixture first, then test storage, towel reach, ventilation, lighting, and cleaning access.
Step by step
Measure the finished envelope
Record wall lengths, ceiling changes, window and door positions, service points, and thickness added by finishes.
Place the critical clearances
Protect comfortable space at the toilet, basin, shower entry, drawers, and door before adding decorative features.
Coordinate wet and dry zones
Keep towels, storage, outlets, and frequently used surfaces away from direct spray while maintaining easy reach.
Test the room in use
Walk through entry, showering, drying, grooming, cleaning, and laundry tasks. Check each door and drawer in both open and occupied conditions.
Expert tips
- A mirrored cabinet can combine shallow storage and task lighting.
- Wall-hung elements expose more floor and simplify cleaning.
- A wider shower opening may be more useful than a tiny extra cabinet.
Common questions
Does a small bathroom need small tiles?+
No. Larger tiles can reduce grout lines, while smaller tiles can suit falls and curves. Layout and proportion matter more than a single size rule.
Should the bathroom door open outward?+
It can improve usable space and emergency access, but local rules, circulation, and adjacent rooms must be checked.
Can I move the toilet?+
Often, but waste pipe routing, floor structure, ventilation, approvals, and cost can make it a major change.
