The Art of Designing a Small Bathroom That Does Not Feel Small

Most people planning a small bathroom renovation immediately start compromising. Shower only. No bath. Keep it simple.

Here is what we would tell you: stop compromising before you have even started.

Whether you are working with a narrow ensuite in London or a compact family bathroom in Surrey, small bathroom design ideas that actually work all share one thing in common, they start with intention, not limitation.

Take this ensuite. It is compact, but it has both a bath and a shower. The trick? They share the same wet zone, with a single frameless glass screen separating this area from the rest of the bathroom instead of a full wall. Continuous large-format marble effect tiles, grout lines – invisible. Nothing interrupting the eye. On paper, small. In person, it feels like a luxury hotel bathroom.

Small Bathroom Layout Ideas: The Decision That Changes Everything

In a small bathroom, the way you frame and position each element determines how spacious the room feels, not the square footage.

A narrow bathroom does not have to feel like a corridor. In this bespoke project, a full-length floating vanity sits at one end, a black steel-framed shower enclosure anchors the other and nothing touches the floor that does not have to. No pedestal, no bulky enclosure. The floor runs uninterrupted from one end to the other, and the room feels twice as generous because of it.

The black steel shower frame is doing something clever here too. It separates the wet and dry zones without using a wall, so the marble-clad shower is visible the moment you walk in. In a narrow room, borrowed depth is everything.

Wood-effect floor tiles laid lengthways. A vanity spanning the full width. A bespoke mirrored cabinet that reflects the marble shower wall behind you. Every detail is directing the eye further into the room. That’s layout working exactly as it should.

You can see more examples of how we approach layout across our bathroom case studies.

The bathrooms you see are all real projects designed and installed by us and every single one proves that size is rarely the limiting factor. Thoughtful design is.

Storage: The Best Kind Is the Kind You Can Not See

You do not need more storage in a small bathroom. You need storage that hides better.

Look at the upper wall in this bathroom. It looks like one continuous surface. It is not. Those panels are bespoke cabinet doors, faced in the same large format marble effect tiles as the walls around them, completely invisible until you open them. Full wall of storage. Zero visual clutter.

Between the cabinets and the bath, there is a full-width illuminated niche, recessed flush into the marble and backlit with warm LED light. Most people think it is a design feature. It is also where everything lives day to day.

The floating walnut vanity hovers above the floor on an LED kickplate. A wall-hung WC with a concealed cistern means nothing unnecessary is touching the floor anywhere in this room. When storage disappears into the design, the whole bathroom feels calmer and bigger.

Materials: Small Rooms Can Handle More Than You Think

The biggest material mistake in a small bathroom is not going too bold. It is going halfway and losing your nerve.

This is a cloakroom, one of the smallest spaces we design. It is also one of the most talked-about rooms in the house.

Bold botanical wallpaper covers the full upper half of the room. Chartreuse yellow, oversized florals, birds. Not a feature wall, the entire upper half. In a space this size, that confidence works because the lower half is anchored in large-format white marble effect tile, clean and uninterrupted. Wild above. Refined below. Brass throughout. The contrast is what makes it extraordinary. Tiles are doing a lot of heavy lifting in a room this size, our guide on how to make a small bathroom look bigger with tiles explains exactly which choices make the biggest spatial difference.

The opposite wall goes to deep black textured stone. A vessel basin sits on a floating marble shelf spanning the full width, with open floor beneath it. Two brass column wall lights flank the mirror like jewellery. Even the cistern button is brass.

This is what bespoke bathroom design delivers, spaces that reflect personality, confidence, and thoughtful craftsmanship rather than short-lived trends.

Before the Tiles, Before the Fittings, There Is the Plan

Every Kallums Bathrooms project begins with a detailed design illustration, a precise visualisation of how every element will sit within the space before a single tile is laid. For smaller bathrooms especially, this stage is where the real thinking happens. Where the shower goes, how the door swings, where storage is built in rather than added on. The illustration above is a real example of how we plan a compact bathroom, a bath and shower sharing the same zone, a recessed niche already in the wall, a vanity tucked to make every centimetre count.
