A small bathroom does not have to feel cramped or compromised. With thoughtful choices around fixtures, layout, and finishes, even a compact UK bathroom, common in flats, terraces, and older properties, can feel spacious, functional, and genuinely well designed.
Choosing Space-Saving Fixtures
Wall-Hung Sanitaryware
Wall-hung toilets and basins, mounted with the cistern concealed behind the wall or in a unit, free up visible floor space and make cleaning underneath far easier, both of which help a small room feel more open.
Corner Basins and Baths
A corner basin or a shaped corner bath makes use of space that would otherwise sit empty, without sacrificing the comfort of a full-size fixture elsewhere in the room.
Shower Over Bath vs Walk-In Shower
If your household has no real need for a bath, replacing it with a walk-in shower can make a small bathroom feel considerably larger, since it removes a bulky fixture and opens up sightlines across the room. If a bath is still needed, a shower-over-bath with a sliding shower screen rather than a hinged door saves valuable clearance space.
Making a Small Bathroom Feel Bigger
- Large-format tiles: fewer grout lines create a cleaner, more expansive look than lots of small tiles
- Light, neutral colour schemes: pale walls and floors reflect more light and avoid the room feeling boxed in
- A large mirror: reflects light and visually doubles the sense of space, particularly opposite a window if one exists
- Glass shower screens over shower curtains: maintain clear sightlines across the room rather than breaking it up visually
- Recessed niches: built into the shower wall for storage, avoiding the need for bulky external shelving units
Storage Solutions for Small Bathrooms
- A mirrored cabinet doubles as both storage and a mirror, without needing extra wall space
- Wall-mounted shelving above the toilet makes use of an often-overlooked vertical space
- A vanity unit with built-in storage beneath the basin replaces an exposed pedestal with genuinely useful cupboard space
- Slim, tall storage units fit into narrow gaps that would otherwise go unused
Lighting a Small Bathroom Well
Layering light sources, a central ceiling light, a mirror light for grooming tasks, and where possible some natural light, makes a small bathroom feel brighter and more comfortable than relying on a single overhead fitting. All bathroom lighting must meet the relevant IP (ingress protection) rating for its zone, since bathrooms have specific electrical safety requirements around water exposure.
Budgeting for a Small Bathroom Renovation
| Scope | Typical UK Cost Range |
|---|---|
| Cosmetic refresh (re-grouting, new fittings, repaint) | £800 to £2,000 |
| Mid-range renovation (new suite, tiling, flooring) | £3,500 to £7,000 |
| Full renovation (including plumbing and electrical work) | £7,000 to £12,000+ |
Do You Need Planning Permission for a Bathroom Renovation?
Most bathroom renovations, including refitting an existing bathroom, do not require planning permission. Building Regulations do apply to electrical and plumbing work, particularly relating to ventilation, electrical safety zones, and drainage, so it is worth confirming any significant rework, especially adding a new bathroom where none existed, meets current requirements.
Frequently Asked Questions
Should I remove the bath in a small bathroom?
This depends on your household’s needs. Removing a bath in favour of a walk-in shower can make a small bathroom feel significantly larger, though it is worth considering resale appeal, since some buyers specifically look for at least one bath in a property.
What is the best flooring for a small bathroom?
Large-format vinyl or porcelain tiles work well, offering water resistance and a clean, expansive look with minimal visible grout lines.
How can I add storage without making the room feel smaller?
Recessed shower niches, mirrored cabinets, and wall-mounted shelving all add storage without protruding into the room the way a freestanding unit would.
