A 5x8 bathroom fits three fixtures — toilet, sink, and tub or shower — along a single wet wall, giving you 40 square feet to work with once you subtract the door swing.
By Free Room Planner Team · Last updated: August 2026That's the honest starting point. Most 5x8 bathrooms follow the same basic logic because plumbing wants to stay on one wall. But the way you arrange those three fixtures — and where you steal storage — changes everything about how the room feels.
Below are four layouts that work in a 5x8 space, with real measurements and the trade-offs of each. Test them yourself before you commit to any of them.
What are the standard measurements for a 5x8 bathroom?
A 5x8 bathroom measures 60 inches (152cm) by 96 inches (244cm). The 8-foot wall usually holds all three fixtures in a row, because keeping plumbing on one side keeps the cost down and the layout simple.
Here are the fixture footprints you're planning around:
- Toilet: roughly 30 inches deep, 20 inches wide, with 21 inches clearance in front
- Vanity/sink: 24 to 36 inches wide, 21 inches deep
- Standard tub: 60 inches long, 30 inches wide — it fits the short wall exactly
- Shower: 32 to 36 inches square as a minimum
Measure your actual room first. Old houses drift, and a wall that's 2 inches shorter than you assumed can push a vanity out of reach.
Layout 1: Classic three-in-a-row
Put the tub on the far short wall, then the toilet, then the sink nearest the door. This is the arrangement most fitters recommend because it clusters all the plumbing and leaves a clear 30-inch walkway down the middle.
The vanity by the door means you reach the sink first — handy for quick hand-washing. It's the safest choice for resale and the easiest to quote.
Layout 2: Tub against the long wall
Run a 60-inch tub along the 8-foot wall instead of the short one. This frees the opposite wall for a wider vanity — up to 36 inches — plus a slim storage tower.
The catch: the toilet gets squeezed into a corner, so check you have 15 inches from its centre to the nearest wall. Below that, it feels cramped and fails most comfort guidelines.
Go this route if storage matters more than a roomy bathing spot.
Layout 3: Walk-in shower swap
Drop the tub and fit a 36-inch square walk-in shower in the corner. Suddenly you've got floor space for a proper 36-inch vanity and a taller cabinet.
A walk-in shower makes a 5x8 feel bigger because a glass panel lets your eye travel the full length of the room. It's the top choice for adults with no young children, and it edges toward accessible bathroom design too.
One trade-off worth naming: skipping the tub can affect resale in family homes, where buyers still expect at least one bath.
Layout 4: Corner sink for extra breathing room
Swap a standard vanity for a corner sink and you reclaim the wall for a full-length storage unit or a wider door swing. Corner sinks suit the tightest 5x8 rooms where the door and toilet keep colliding.
You lose counter space — a corner sink gives you almost none — so pair it with wall-mounted storage above the toilet and a mirrored cabinet.
How do you fit storage into a 5x8 bathroom?
Build storage upward and into the walls, not out onto the floor. In a 40-square-foot room, every inch of floor you keep clear makes the space feel calmer.
Three storage moves that work:
- Recessed niche in the shower or tub wall for bottles — steals depth from the wall cavity, not the room
- Mirrored cabinet above the sink instead of a flat mirror
- Over-toilet shelving or a slim tower in dead corner space
Wall-mounted vanities help too. Seeing floor run underneath the unit tricks the eye into reading the room as larger than it is.
Why plan your 5x8 layout digitally before renovating?
Because a 2-inch mistake in a 40-square-foot room is a disaster, not a rounding error. Planning on screen lets you drag the toilet, sink, and tub around and watch the clearances update live — before a fitter cuts anything.
Sketching on paper hides the door swing, the radiator, and the pipe you can't move. A digital plan with snap-to-grid measurements catches all three. You draw the walls, drop in fixtures, and export a clean floor plan to hand your fitter — no sign-up, no download.

Frequently Asked Questions
Quick answers to the questions homeowners ask most when planning a 5x8 bathroom.
Can you fit a bath and a separate shower in a 5x8 bathroom?
Not comfortably. A 5x8 room fits either a tub-shower combination or a standalone walk-in shower, but rarely both as separate fixtures. There simply isn't 40 square feet to spare once you add the toilet and sink with proper clearances.
What is the best fixture order in a 5x8 bathroom?
Most fitters place the vanity nearest the door, the toilet in the middle, and the tub or shower on the far wall. This keeps plumbing grouped, gives a clear central walkway, and puts the sink where you use it most.
How much clearance does a toilet need in a small bathroom?
Allow at least 15 inches from the centre of the toilet to any side wall, and 21 inches of clear space in front. Drop below these and the room feels cramped and awkward to use daily.
Do I need design software to plan a 5x8 bathroom?
No. A free browser-based floor planner does the job without complex software or a download. You draw the walls to your measured dimensions, drag fixtures into place, and export a floor plan to share with your fitter.
Does removing the tub hurt resale value?
It can in family homes, where buyers expect at least one bath in the property. If your 5x8 is the only bathroom, keep a tub-shower combination. If it's a second or en-suite, a walk-in shower is usually the smarter use of space.
