A downstairs toilet is usually the smallest room in the house and the one every guest ends up seeing. It is also the room where you can get away with the most. There is so little floor and wall to cover that a bold choice costs less than it would in a main bathroom, and a clever layout can make a very tight space feel considered rather than squeezed.
This guide shares downstairs toilet ideas that work in real UK homes, from layouts for small and very small cloakrooms to panelling, bold decor and space-saving fittings.
Downstairs toilet ideas that work
Most cloakrooms fall flat for the same reason: nobody planned them. The toilet goes where the pipe is, a basin gets squeezed in, and the walls stay magnolia. The ones that work usually do a few simple things well.
- Pick one star feature: a deep paint colour, a patterned wallpaper or a feature tile, used confidently, looks far better than three ideas competing in a space this size.
- Light it properly: a single ceiling light makes a small room look flat. Add wall lights either side of the mirror, or a warm lamp-style fitting, so the room feels like part of the house.
- Use the walls, not the floor: a slim shelf above the cistern, a couple of hooks and a wall-hung cabinet add storage without eating into floor space.
- Keep the floor simple: one continuous finish that wipes clean makes the room look larger and easier to look after.
- Plan the ventilation: if the room has no opening window it will need an extractor fan, so build that in from the start rather than adding it later.
Small finishing touches like a proper mirror, a hand towel rail and a little warmth go a long way in a room this size.
Small & very small layouts
Size is the first thing to pin down. As a rough guide, a cloakroom should not go smaller than about 700mm wide by 1,300mm long, and 800mm by 1,400mm is more comfortable. If you want a toilet and a full-size basin with room to move, aim for around 900mm by 1,800mm. You also need roughly 500mm of clear space in front of the toilet for your legs.
- Line everything up on one wall: in a long, narrow room, putting the toilet and basin along the same wall leaves a clear walkway down the other side.
- Turn to a corner: in a room that is only just wide enough, a corner basin uses space that would otherwise go to waste.
- Rethink the door: a door that swings into the room eats up floor space. A sliding or pocket door gives that space back, and an outward-opening door can work if it will not swing into a hallway people use.
- Plan under-stairs rooms around headroom: you sit to use the toilet but stand at the basin, so the lowest part of a sloping ceiling suits the toilet and the tall end suits the basin.
- Check the pipework early: the position of the soil pipe decides which layouts are possible and what they will cost, which is why a survey should come before a final design.
Many of these tricks also apply to a small ensuite, and our guide to designing a small ensuite bathroom without compromise goes further on getting the most from a tight room.
Panelling & bold decor
A cloakroom has no bath or shower, so it sees far less steam and splashing than a main bathroom. That makes it one of the easiest rooms in the house to be brave with.
- Panelling: half-height or full-height panelling painted in a deep shade adds character and protects the walls from knocks and splashes. Use a moisture-resistant or bathroom paint, especially in a room with no window.
- Dark, moody colours: deep green, navy, charcoal and aubergine all suit a small room. Painting the ceiling the same colour makes the space feel wrapped around you rather than boxed in.
- Statement wallpaper: a wipeable or vinyl paper works well, but keep it out of direct splash range and add a splashback behind the basin.
- Pattern on the floor: with so little floor to cover, a patterned or handmade tile is easier to afford and becomes the thing people remember.
- A bigger mirror and warmer light: a large mirror bounces light around and makes the room look wider, and warm bulbs stop dark colours feeling gloomy.
If you would rather keep things calm, our modern beige tile bathroom ideas show how a neutral palette can still look good.
Space-saving basins & toilets
In a very small room the fittings do most of the work, and there is plenty of choice now.
- Cloakroom basins: made smaller and shallower than standard basins, and the narrowest ones suit rooms where a normal basin would stick out into the walkway.
- Corner basins: designed to sit tight in a corner, they use space most small rooms never use.
- Semi-recessed basins: part of the bowl sits back into the wall or a cabinet, so it projects less into the room.
- Wall-mounted taps: with the tap on the wall, the basin can be shallower and the rim stays clear.
- Wall-hung toilets: lifting the toilet off the floor lets the floor run through to the wall, which makes a small room look bigger and easier to clean. They sit on a frame, and the boxing-in above it can double as a shelf.
- Short-projection toilets: the pan sits closer to the wall, which can win back precious centimetres in front of it.
- Slimline cisterns: concealed or low-profile cisterns shave depth from the wall behind the toilet.
Choosing between all of these is easier when you can see the room. Our bathroom design service uses 3D software to show you the layout before any work starts, with a consultation at our Caterham showroom or a visit to your home. Call 01883 330051 to get started.
