Who this guide is for
- Owners planning storage as part of a bathroom renovation.
- Households short on bathroom storage and tired of cluttered surfaces.
- Anyone working with a small bathroom and tight constraints.
Vanity storage
The vanity is usually the workhorse of bathroom storage. Drawers and cabinets under the basin suit daily items, though plumbing under the basin limits how the space can be used — plan around it.
Recessed storage
Recessed niches and cabinets add storage without projecting into a tight room. Their position depends on what is inside the wall, so they must be planned with the contractor and never cut into without checking for services or structure.
Wall storage
Shelves and wall cabinets use vertical space that small bathrooms often waste. Keep them clear of door swings and splash zones, and choose fixings appropriate to the wall.
Towel storage
Towels need somewhere dry and reachable from the shower or bath. Plan whether they live in the vanity, on a rail, in a niche or on open shelving, and keep them out of constant splash.
Cleaning supplies
Cleaning products need a safe, contained spot — ideally away from children and not mixed with toiletries. A dedicated, enclosed space keeps them tidy and out of sight.
Moisture-sensitive items
Some items degrade in a humid bathroom. Store moisture-sensitive things in closed, ventilated storage, and rely on good ventilation to keep humidity down overall.
Lighting, mirrors and small-bathroom constraints
Mirrors and mirror cabinets add storage and bounce light, and good lighting makes a small bathroom feel larger. In tight rooms, every storage decision competes with circulation and door swings, so plan storage and movement together. Any integrated lighting must be installed by a qualified electrician.
Bathroom storage planning checklist
- 1Inventory what the bathroom actually needs to store.

- 3Position any recessed niches with the contractor, checking the wall first.
- 4Use wall storage clear of door swings and splash zones.
- 5Give towels a dry, reachable home.
- 6Provide a safe, enclosed spot for cleaning supplies.
- 7Store moisture-sensitive items in closed, ventilated storage.
- 8Use a mirror cabinet to combine storage, light and reflection.
- 9In small rooms, plan storage and circulation together.
- 10Have any integrated lighting installed by an electrician.
Common mistakes to avoid
- Planning storage volume without accounting for plumbing under the vanity.
- Cutting recessed niches without checking for services or structure.
- Placing shelves in splash zones or across door swings.
- Leaving towels somewhere that stays damp.
- Mixing cleaning chemicals with toiletries within reach of children.
- Ignoring how storage competes with circulation in a small bathroom.
When to involve a professional
- Recessed storage near services or structure must be planned with the contractor.
- Integrated mirror or cabinet lighting must be installed by a qualified electrician.
- Any work affecting plumbing or waterproofing should be carried out by licensed trades.
- Fixing methods should suit the wall type and the load.

Frequently asked questions
Questions readers ask about this topic
How do I add storage to a small bathroom?
Use vertical and recessed space — wall cabinets, niches and mirror cabinets — and plan storage alongside circulation so it does not block movement. Recessed niches must be planned with the contractor after checking the wall.
Where should towels be stored?
Somewhere dry and reachable from the shower or bath, out of constant splash — a rail, niche, vanity or shelving, depending on the room. Good ventilation helps them dry between uses.
Can I cut a niche into the wall myself?
No. Recessed niches depend on what is inside the wall, including possible services and structure, and they affect waterproofing. They must be planned and built with the contractor.
