A small bathroom layout is a floor plan arrangement of toilet, basin, and shower or bath within a compact space — commonly defined as under 5 m² (54 sq ft) — that maximises clearance and usability within tight dimensions.

Most small bathroom guides show you photos you can't act on. You see a beautiful layout, wonder if it would fit your room, and have no way to check — so you're back to guessing with a tape measure and a rough sketch.
This page works differently. You get a free interactive planner you can open right now, plus three ready-made configurations for the most common small bathroom sizes. Draw your walls, drop in fixtures, and get live measurements — no sign-up, no download, no cost.

TL;DR
- Use the free browser-based planner to draw and test your layout before committing to anything.
- The most common small bathroom sizes are 5×8 ft (1.5×2.4 m), 6×8 ft (1.8×2.4 m), and half bath (roughly 0.9×1.8 m / 3×6 ft).
- Key clearances: 600 mm (24 in) in front of the toilet, 800×800 mm (32×32 in) minimum shower enclosure.
- Four layout patterns cover almost every compact bathroom: single-wall, L-shape, wet room, and split.
- Export your finished floor plan as an image and send it directly to your builder — no verbal description needed.

Pre-Built Small Bathroom Layouts You Can Open and Edit
These aren't concepts — they're named starting points you can load into the planner and adjust to match your actual room. Each one has a set of fixtures already placed at standard dimensions. Change what doesn't fit. Keep what does.
Template 1 — 5×8 Bathroom Layout (Single-Wall)
Room size: 1.5×2.4 m (5×8 ft)
Fixtures: Toilet, pedestal basin, shower enclosure or standard bath
Style: Single-wall
In a 5×8 ft room, the single-wall arrangement is the most space-efficient starting point. The toilet and basin sit along one long wall; the shower or tub occupies the short wall opposite the door.
This layout works because it keeps the floor area in front of you clear when you enter. The planner lets you swap the basin and toilet positions in seconds — useful if your soil pipe is on a specific side.

Template 2 — 6×8 Bathroom Layout (L-Shape)
Room size: 1.8×2.4 m (6×8 ft)
Fixtures: Toilet, wall-hung basin, corner shower enclosure
Style: L-shape
The extra 300 mm (12 in) of width in a 6×8 ft bathroom opens up an L-shape arrangement. The shower goes into one corner; the toilet and basin run along the adjacent wall.
This keeps the movement path through the room open and places wet and dry zones on separate walls — a practical separation that makes the room easier to use day-to-day.

Template 3 — Half Bath / Powder Room Layout
Room size: 0.9×1.8 m to 1.2×1.5 m (3×6 ft to 4×5 ft)
Fixtures: Toilet and basin only
Style: Minimal two-fixture
A half bath needs just two fixtures, but tight clearances make placement critical. The minimum recommended clearance in front of a toilet is 600 mm (24 in), and a corner basin can reclaim significant floor space versus a standard pedestal.
The planner's live measurements flag instantly if you've placed fixtures too close together — removing the guesswork that causes expensive mistakes on site.

Standard Small Bathroom Dimensions to Know Before You Plan
Entering your room's actual measurements before you start placing fixtures saves you from redesigning the whole layout later. These are the four clearances that matter most in a compact bathroom:
| Fixture / Zone | Minimum dimension |
|---|---|
| Clearance in front of toilet | 600 mm / 24 in |
| Clearance either side of toilet | 150 mm / 6 in |
| Minimum shower enclosure | 800×800 mm / 32×32 in |
| Standard basin depth | 400–500 mm / 16–20 in |
These figures reflect widely used guidance from bathroom fitting standards across the UK and North America. Knowing them before you open the planner means you can check every fixture position against real requirements as you go — rather than discovering a problem after ordering.
The Four Most Common Small Bathroom Layout Patterns
Almost every compact bathroom fits into one of these four arrangements. Understanding which pattern matches your room shape before you start planning saves significant time.
Single-wall — All three fixtures run along one wall. Best for very narrow rooms (under 1.5 m / 5 ft wide) where placing fixtures on opposing walls would leave no usable floor space. Common in en-suite bathrooms carved out of a bedroom.
L-shape — Fixtures split across two adjacent walls, with the shower or bath in one corner. Works well in rooms that are slightly wider than they are long. The most versatile arrangement for standard small bathroom dimensions.
Wet room — The shower area is open-plan with no enclosure, typically defined by a sloped floor drain. Suits very small or awkward rooms because it removes the enclosure footprint entirely. Requires specialist waterproofing.
Split (separate toilet compartment) — The toilet is partitioned from the wash and shower area. More common in European layouts and older UK terraced houses. Useful when multiple people need to use different parts of the bathroom at the same time.

How to Arrange Fixtures for Maximum Space
Three placement decisions make the biggest practical difference in a small bathroom. Get these right and the rest of the layout follows naturally.
- Place the toilet away from the door swing. The door arc is the single most overlooked clearance in a compact bathroom. Without a clear floor plan, contractors may assume the door swings inward and order fixtures positioned for the wrong wall — a costly correction. Draw the door swing in the planner first, then position fixtures around it.
- Choose a corner basin or wall-hung basin. A standard pedestal basin takes up 400–500 mm (16–20 in) of floor depth. A corner basin or wall-hung model reclaims that space entirely, leaving a clear movement path between the door and the shower.
- Position the shower or bath to preserve a central aisle. The usable space in a small bathroom is the floor area between fixtures, not the total square footage. Place the largest fixture — shower or bath — against the far wall so you can move freely from the door to each fitting without stepping around obstacles.
How to Share Your Small Bathroom Layout With a Builder or Fitter
Once your layout is drawn, export it as a clean image directly from the planner. Send that image to your builder, bathroom fitter, or supplier instead of describing the layout verbally or sending a hand-drawn sketch.
A to-scale floor plan reduces the back-and-forth that delays quotes and causes on-site surprises. Fitters can see exactly where soil pipes need to connect, where the shower drain sits, and how much clearance exists around each fixture — before they set foot in the room.

Common Mistakes to Avoid in a Small Bathroom Layout
These are the errors that cause the most expensive rework. The planner catches most of them automatically — but it helps to know what to look for.
- Ignoring door swing radius. A standard door sweeps 700–900 mm (28–35 in). Place a toilet or basin inside that arc and you'll be redesigning the layout after fitting.
- Forgetting the extractor fan position. Building regulations in the UK require mechanical ventilation in bathrooms without openable windows. Plan where the fan goes before you finalise ceiling and wall fixture positions.
- Choosing a full-size bath when only a shower fits. A standard bath is 1,700×700 mm (67×28 in). In a 5×8 ft room, that often leaves inadequate clearance. The planner's live measurements show the conflict immediately.
- Not accounting for wall thickness. Internal walls are typically 100 mm (4 in) thick; external walls can be 300 mm (12 in) or more. Measure the internal room dimensions — not the external footprint — before you start.
- Planning storage last. A bathroom with no storage turns functional quickly into cluttered. Decide where a recessed shelf, vanity unit, or cabinet goes before you lock in fixture positions — not after.
Conclusion
A good small bathroom layout is about clearances and fixture order, not square footage. Get the door swing, toilet clearance, and movement path right and the rest of the design falls into place.
