Most bathrooms in the UK are small. If yours is around 2m x 3m or smaller you're in the majority, not the exception. London homes in particular, whether Victorian terraces, purpose-built flats, or new builds, tend to have bathrooms that require real thought about what goes where and what to leave out entirely.
The good news is that a small bathroom done well can feel just as considered as a large one. The difference is mostly about making smarter product choices upfront, rather than trying to squeeze in everything you'd put in a bigger room. Here's what actually makes a difference.
Layout First — Everything Else Follows
Before you look at a single tile or tap, sort the layout. This is where most small bathroom renovations go wrong — people fall in love with a product and then try to make the room work around it, rather than the other way around.
Measure the room properly. Not just length and width, but where the door swings, where the window sits, where the soil pipe runs, and where the existing plumbing is. Moving plumbing in a small bathroom is expensive and often not worth it. The best small bathroom layouts almost always work with the existing pipe positions and use clever product choices to make that work.
A few layouts worth considering for tight spaces:
Linear layout — toilet, basin, and shower in a row along one wall. Works well in narrow en suites and rooms that are longer than they are wide. Simple plumbing, easy to tile.
Wet room or open shower — removing the shower tray and enclosure and waterproofing the whole floor can free up visual space considerably. Not always possible without significant floor work, but worth asking your plumber about if you're doing a full renovation.
Shower over bath — if you want both a bath and a shower and the room is too small for separate fixtures, a shower bath with a bath screen is the most practical solution. Takes the same footprint as a regular bath and gives you both.
Wall-Hung Toilets: Worth It in a Small Bathroom
If there's one upgrade that makes the biggest difference in a compact bathroom, it's switching from a close-coupled toilet to a wall-hung one. The cistern goes inside the wall — inside a frame that's roughly 15cm deep — and the pan hangs off the wall with nothing touching the floor. That means you can see the floor under the toilet, which makes the room feel noticeably larger. It also makes cleaning significantly easier.
The pan itself tends to be slightly more compact than a standard close-coupled toilet, and you can set the height of the flush buttons, which is a small but useful detail. The wall frame (called a WC frame or concealed cistern frame) needs to be installed before the tiling, so it's a decision to make at the start of a renovation rather than as an afterthought.

Floating Vanity Units Over Pedestal Basins
Pedestal basins look good in certain settings — particularly period-style or very traditional bathrooms — but in a small modern bathroom they have two problems: they hide almost nothing, and they sit on the floor, breaking up the visual space.
A wall-mounted vanity unit with an integrated basin gives you storage underneath and visible floor beneath it, which does the same trick as the wall-hung toilet. Even a narrow 400mm or 450mm vanity unit provides enough storage for daily essentials and transforms a basin from a single fixture into a proper functional zone.
For very tight spaces, cloakroom vanity units — typically 300–400mm wide — are worth looking at. They're designed specifically for small rooms and pair well with a compact basin. Take a look at our bathroom furniture range.
Shower Enclosures for Small Bathrooms
The shower enclosure has more impact on how spacious a bathroom feels than almost anything else, and the wrong choice can make a small room feel oppressive.
Avoid framed enclosures if you can. The chunky aluminium frames on older-style shower enclosures create visual boundaries that cut the room up. Frameless or semi-frameless glass makes the shower feel part of the room rather than a separate box inside it.
Bi-fold doors work well where space is tight. A bi-fold door folds inward on itself, so it needs no clearance in front of it when it opens. Useful if your bathroom door and shower door would otherwise conflict, or if you're working with a very narrow run of floor space.
Sliding doors beat hinged ones in most small bathrooms. A hinged shower door needs a clear arc of space to swing open into — space that's often not available. A sliding door runs along a track and needs no extra clearance at all.
Walk-in panels rather than enclosures. For a sleek, open feel, a single frameless walk-in panel with a return panel is often the cleanest option. It looks more like a wet room than a shower cubicle, and the reduction in visual clutter makes the room feel bigger. You'll need a shower tray with a built-in channel drain, or a wet room floor.

Storage: Think Vertically
Floor space is the thing you have least of in a small bathroom, so everything that can go on the wall, should. That doesn't mean loading every surface with shelving — it means being deliberate about what you need stored, and finding the right home for it.
A mirrored cabinet above the basin is the most efficient use of wall space in a bathroom. You need a mirror. You need storage. A mirrored cabinet gives you both in the same footprint, and the reflective surface also bounces light around the room. A 600mm or 700mm mirror cabinet holds more than most people realise — toiletries, medicines, spare razors — without using a single centimetre of floor or worktop.
A tall cabinet in a corner or against a spare wall — if you have one — earns its place in a small bathroom in a way that wide, low cabinets don't. Vertical storage draws the eye up, which helps a room feel taller, and maximises the height of the room rather than the width.
Recessed niches in shower walls are worth building in during a renovation if your walls allow it. A tiled niche for shampoo and soap costs very little to add during tiling and eliminates the need for a separate shelf or caddy permanently occupying the corner of the shower.
Tiles and Colour: What Actually Makes Rooms Feel Bigger
The common advice is to use light colours in small spaces. It's broadly right, but it's not the full picture.
What actually makes a bathroom feel bigger is reducing the number of visual interruptions — grout lines, different surfaces, contrasting colours that the eye has to process. So a bathroom tiled floor-to-ceiling in one large-format tile with thin grout joints will feel bigger than the same room tiled in a smaller tile with lots of grout lines, even if the colours are similar.
Large-format tiles (600x600mm or larger) on both walls and floor create a continuous surface that reads as one thing rather than many. Keeping the same tile running from floor to wall without a break — or with a very subtle change in finish — eliminates the visual border that normally cuts a room in half.
As for colour: pale works, but a single confident dark colour on all four walls and the floor can also work well in a small bathroom. It removes the variety the eye is trying to process, and if the room has good lighting, a dark bathroom can feel cosy and intentional rather than cramped. The mistake is using multiple colours or too many different materials in a small space — that's what makes rooms feel busy and small.
Lighting Matters More Than People Think
A small bathroom with poor lighting always feels smaller than it is. This isn't about having more lights — it's about having the right ones in the right places.
A single ceiling light in the centre of a small bathroom is the default and usually the worst option. It casts shadows on your face when you're at the mirror (because the light is behind you), and it doesn't do much to lift the corners of the room.
An LED mirror solves the most important lighting problem in a bathroom — getting even, shadow-free light onto your face. A good LED mirror with adjustable colour temperature is far more useful than an overhead spotlight above the basin.
Add a recessed downlight or two in the ceiling to cover the rest of the room, and if budget allows, a small wall light or lit mirror cabinet will make the room feel layered and considered rather than like a box with a light in it.
The Things Not Worth Doing in a Small Bathroom
A few decisions that look appealing but tend not to work well in tight spaces:
A full-size bath when you don't use one. If you shower 95% of the time, a bath takes up roughly a third of your floor space in exchange for very little. A shower-only bathroom — done well — will feel significantly more spacious than one where a bath dominates the room. Be honest with yourself about how often you actually use a bath before committing the space to one.
A double basin. Double basins need a minimum of about 1200mm of wall space to feel right, and in most small UK bathrooms that's either not available or comes at the cost of storage or other fixtures. A single basin with a wider unit beneath it — giving more storage and worktop — almost always makes more sense.
Too many different finishes. Chrome taps, a black towel rail, a brass mirror frame, and brushed nickel flush plate all in the same room creates visual noise. Picking one finish and sticking to it across all the metalwork in a small bathroom makes everything feel more deliberate and calmer.
