Bathroom layout ideas that respect the room you have

A good layout is decided by the door, the soil pipe and the window before any style choice. Here is how to think about where each fitting should go.
Every bathroom layout is a negotiation between what you want and three fixed facts: where the door opens, where the soil pipe runs and where the window sits. Layouts that ignore those facts look fine on paper and fail in the room.
This guide covers the layout decisions that matter, from keeping things still to moving everything. Our bathroom design service plans layouts properly, and the bathroom planning checklist helps you prepare for that conversation. More inspiration lives in the bathroom ideas hub.
The cheapest layout is the one you already have
Keeping the toilet, basin and bath or shower where they are is the single biggest cost saver in any renovation, because the soil pipe and supply pipework stay put. A like-for-like layout with better fittings and finishes transforms a room without touching the plumbing runs.
That does not mean the room has to feel the same. Swapping a bath for a shower on the same footprint, changing the basin for a vanity unit or rehanging the door to open against a different wall all change how the room works while the pipework stays still.
The toilet barely moves, and here is why
The toilet is tied to the soil stack by a large pipe that needs a steady fall. Moving it along the same wall is usually straightforward; moving it across the room means a new soil run, which is possible but adds real work and sometimes a boxed-in section of pipe.
When a layout plan starts with moving the toilet, the first question at the survey is where the stack is. Everything else in the room is flexible; that pipe mostly is not.
Showers and baths: the big footprint decisions
The bath footprint is the most valuable space in a small bathroom. A bath replaced by a walk-in shower on the same footprint often frees visible floor and makes the room feel larger, while a P shaped shower bath keeps both functions where the room must serve a family.
Corner showers release the long wall for storage or a bigger basin. The bath or shower guide helps with the keep-or-swap decision, and the shower enclosure types guide compares what can go in the space you free up.
Basins, storage and the door swing
The basin is the most flexible fitting in the room. A wall-hung basin frees the floor beneath it, a corner basin uses dead space, and a vanity unit trades a little floor area for a great deal of storage. In a room short on storage, the vanity usually wins.
The door is the layout's silent saboteur. A door that swings into the room can claim a quarter of the usable floor. Rehanging it to open against a clear wall, or swapping to an outward-opening or sliding door where the landing allows, is cheap work with an outsized effect.
Clearances: the numbers that stop regrets
Layouts fail on clearances, not aesthetics. You need comfortable space in front of the toilet, room to stand at the basin without the shower screen behind you, and a door that opens without hitting anything. These are measured in centimetres and checked on the plan before anything is ordered.
A scaled sketch, even a rough one with measurements, catches layout problems while they are still free to fix. That sketch is exactly what the survey produces, and it is why the complete bathroom renovation service starts with measuring rather than catalogues.

Questions
Frequently asked
Can I move my toilet to a different wall?
Sometimes, but it is the most constrained fitting in the room because of the soil pipe. Moving it along the same wall is usually simple; across the room means new pipework. The survey establishes what your stack allows.
What is the best layout for a small bathroom?
Usually the existing one, improved: a shower on the bath footprint, a vanity unit for storage and a door that opens against a clear wall. Small rooms reward keeping the plumbing still and spending on fittings and finish.
How much space does a toilet need?
Allow comfortable room in front and to the sides so the toilet is usable, not just fitted. Exact clearances depend on the fitting, and they are checked on the measured plan before anything is ordered.
Should the bath or the shower go under the window?
Neither is ideal, but a bath tolerates a window better than a shower because less water reaches the reveal. If a shower must sit under a window, the reveal needs tiling and sealing like the rest of the wet zone.
