Small bathrooms are one of the most common challenges I come across when working in Surrey, Sussex and Kent homes. Victorian terraces, semi-detached houses with awkward layouts, and loft conversions all tend to produce bathrooms where every centimetre counts. The good news is that with the right design decisions — fixtures, tiles, layout and lighting — a compact bathroom can feel genuinely spacious and luxurious. Here are the ideas I reach for most often.
Wall-Hung Toilets and Floating Vanities
If you take nothing else from this post, take this: wall-hung toilets and floating vanities are the single biggest visual upgrade you can make to a small bathroom. By raising the pan and vanity unit off the floor, you expose a continuous strip of flooring that tricks the eye into reading the room as larger. Wall-hung toilets also conceal the cistern inside the wall or a slim duct panel, removing the bulky back-tank that eats into floor space. Floating vanities come in depths as shallow as 35 cm — ideal when you're working around a tight run — and the open space beneath can accommodate a small step stool or just kept clear to maintain that airy feel.
Large-Format Tiles: Less Grout, More Space
It sounds counterintuitive, but bigger tiles make small rooms feel bigger. The logic is simple: fewer grout lines mean less visual noise. A 600 x 1200 mm rectified tile laid on the floor and continued up the walls (a technique called book-matching or continuous surfacing) removes the horizontal interruptions that chop a small room into sections. Light stone-effect porcelain in warm white or pale greige works particularly well. Avoid busy patterns or dark colours on both floor and walls simultaneously — reserve contrast for one surface only.
Frameless Shower Enclosures vs Wet Rooms
For tiny bathrooms, the choice between a frameless glass shower enclosure and a full wet room comes down to budget and the level of disruption you're prepared for. A frameless enclosure — no chunky aluminium frame, just clear glass panels — is the lighter-touch option. It keeps water contained, looks modern, and doesn't require full-room tanking. A wet room, however, removes the enclosure entirely. The shower area flows into the rest of the floor, with a linear drain set into the tiles. This opens up the visual field dramatically and is a superb choice in bathrooms under 3 m². The trade-off is cost: a proper wet room needs thorough waterproofing (tanking) across all walls and the floor, adding roughly £300–£500 to the installation. For most small bathrooms in older Surrey homes, I'd lean toward the frameless enclosure unless the budget allows for the full wet room treatment.
Mirror Tricks
A large mirror is one of the cheapest ways to double the perceived size of a bathroom. Rather than a modest cabinet mirror above the basin, consider a full-width mirror that runs edge to edge across the vanity wall, or even floor-to-ceiling mirrored tiles on one wall. Lit mirrors — with an LED backlight or integrated lighting strip — add depth and eliminate harsh overhead shadows, making the room feel both larger and more flattering.
Vertical Storage
Floor space is precious; wall space above eye level usually isn't being used at all. Tall, slim storage columns (sometimes called "tallboy" units) make use of the full wall height. Fitted shelving in alcoves beside the vanity, or a recessed niche cut into a stud wall between the shower and the exterior, can hold toiletries without taking up any floor projection at all. Think vertically and keep the floor clear.
Recessed Shelving
A recessed shelf built into the shower wall — a niche, typically 300 x 600 mm — is one of my most-requested additions on small bathroom renovations. It keeps shampoo bottles off the shower tray, removes the need for a hanging caddy that clogs up the visual field, and looks beautifully intentional. The same principle applies in the main bathroom: a recessed medicine cabinet sits flush with the wall rather than projecting out from it, saving 10–15 cm of depth that adds up when the room is only 2 m wide.
Light Colours and the Matt vs Gloss Question
Pale tones — soft whites, warm creams, pale greiges, light sage — reflect more light around the room and make walls feel further away. Gloss tiles amplify this effect by bouncing light, which works brilliantly in a shower area or on a single feature wall. However, full-gloss everywhere can feel clinical and shows watermarks easily. My preferred approach in small bathrooms is a large-format matt tile on the floor (safer underfoot, less slippery) and gloss or semi-gloss on the walls, particularly behind the shower. The contrast in finish adds interest without adding clutter.
Good Lighting
Poor lighting makes even a well-designed small bathroom feel cramped and gloomy. Aim for at least two circuits: ambient overhead lighting (recessed downlights on a dimmer are perfect) and task lighting at the mirror. If you can add a third source — a lit niche, an illuminated shelf, or LED strip under a floating vanity — the layered effect adds real depth. Warm white LEDs (2700–3000K) are far more flattering than cold white and make the room feel more spa-like. Always use IP65-rated fittings in wet zones.
Top 6 Space-Saving Tips for Small Bathrooms
- Wall-hung toilet and floating vanity — expose the floor and the room feels immediately bigger.
- Large-format tiles (600 x 1200 mm+) — fewer grout lines, cleaner look.
- Frameless glass or full wet room — eliminate heavy frames and enclosure clutter.
- Full-width lit mirror — reflect light and double the visual depth.
- Recessed shower niches and alcove shelving — storage with zero floor footprint.
- Layered lighting on a dimmer — ambient, task and accent in one compact room.
A Note on Layout
Sometimes the biggest gains come not from the fixtures themselves but from rethinking the layout. Swapping a bath for a shower-only configuration, relocating the door so it opens outward rather than into the room, or shifting the WC to a short wall can all unlock significant space. These changes involve moving soil pipes or supply pipes, which adds cost, but in a very small bathroom the layout is often the most important variable of all. I always walk through layout options with clients before we agree on a design — it's the conversation that makes the biggest difference.

Frequently Asked Questions
What is the minimum size for a bathroom in the UK?
There is no single legal minimum bathroom size in the UK for an existing property, but building regulations require a bathroom to be large enough to comfortably use all fixtures. In practice, a small bathroom can work from around 1.5 m² for a toilet-only cloakroom, while a full bathroom with bath or shower, WC and basin typically needs at least 3–4 m². New-build requirements may specify minimum dimensions, so always check with your local authority or a qualified fitter.
Are wet rooms good for small bathrooms?
Yes — wet rooms are an excellent choice for small bathrooms. By removing the need for a shower tray, screen frame or enclosure, a wet room opens up visual space and removes trip hazards. The seamless tiled floor can also make the room feel larger. They do require proper waterproofing (tanking) throughout, which adds a small cost, but in a compact room the space gains are well worth it.
