Choose fittings sized for the room, not the showroom
A standard 1700mm bath dominates any room under about 6 m2. A 1500mm or 1600mm bath, or swapping to a shower entirely, frees up circulation space that changes how the whole room feels.
Wall-hung WCs and basins with a concealed cistern remove visible pedestal clutter and make floor cleaning easier, both of which make a small room read as tidier and larger even though the footprint saving is modest, often just 100-150mm.
A corner basin or a slimline 450mm basin instead of a standard 550-600mm unit can be the difference between a comfortable door swing and a cramped one in a tight cloakroom.
Tile formats and layout that genuinely open up a room
Large-format tiles (600x600mm or 600x1200mm) on the floor reduce the number of grout lines, which reads visually as more space. On walls, running tiles vertically to the ceiling rather than stopping at a fixed height draws the eye up and makes the room feel taller.
Using the same tile on the floor and lower walls of a wet room-style shower area, rather than a contrasting border, removes visual breaks that otherwise chop a small room into segments.
Where budget allows, a single feature wall in a bolder tile behind the WC or basin, with everything else in a lighter neutral, adds interest without the whole room feeling busy.
| Area | Recommended format | Why |
|---|---|---|
| Floor | 600x600mm or larger | Fewer grout lines, calmer sightline |
| Shower walls | Match floor tile or 300x600mm vertical lay | Reduces visual chopping of the space |
| Feature wall | Mosaic or patterned 200x200mm | Interest without overwhelming a small footprint |
| Grout | Light grey or matched CG2 grout | Avoids a heavy grid effect that shrinks the room visually |
Light, colour and mirrors
Light wall tones with a warm white light temperature (around 3000-4000K) make the biggest single visual difference of anything on this list, and cost nothing extra to specify.
A mirror sized close to the full width of the basin unit, rather than a small centred mirror, reflects more light and more of the room. An illuminated mirror with a demister pad adds function without extra wall clutter.
Glass shower screens let light travel through the room rather than being blocked by a shower curtain or solid panel, which matters more in a small room than a large one.
Storage that does not eat floor space
Recessed niches built into the shower wall during first-fix, rather than a wall-mounted caddy added afterwards, keep the wall line clean and avoid drilling through waterproofed tiles later.
Wall-hung vanity units with drawers under the basin replace a pedestal and an over-basin cabinet with one piece of furniture, freeing up an entire wall for towel storage instead.
A tall, narrow cabinet in an unused corner often holds more than a wide shallow one and takes up far less usable floor area.
Solve the fixed constraints first
Plan outwards from the soil pipe because the toilet is the least flexible fitting. In a narrow room, keeping the main fittings on one wall protects the walkway, while a shower at the far end with a fixed panel avoids another door swing.
The bathroom door itself can waste valuable floor area. An outward-opening, sliding or pocket door may unlock a better arrangement. In a loft room, place the toilet and bath beneath the lower ceiling and keep full standing height for the shower.
Realistic costs for a small bathroom refresh
A cloakroom or small ensuite refit with the ideas above typically runs from around £2,800 for a straightforward reconfiguration to £6,500 for a premium specification with wall-hung furniture, large-format tiling and a bespoke shower screen.

Your questions answered
Do large tiles really make a small bathroom look bigger?
Yes, primarily because fewer grout lines create a calmer, more continuous surface. The effect is real, not just a design trend.
Is a walk-in shower always better than a bath in a small room?
Not always, it depends on your household. A shower does free up more circulation space, but if you need a bath for children or resale, a shorter 1500-1600mm bath is a good middle ground.
Can you fit a wall-hung WC and basin in an older house?
Usually yes, we build a stud wall or frame to house the concealed cistern and pipework, which also gives us a place to run electrics for lighting or a heated towel rail.
What is the smallest usable ensuite size?
Around 1.5-1.8 m2 can hold a WC, basin and corner shower if the layout is planned carefully, though comfort improves noticeably above 2.5 m2.
How do I stop a small bathroom feeling cold with all that tile?
Underfloor heating under the tile and warm-toned lighting both make a tiled small room feel considerably warmer without changing the tile choice.
