Type the room size, say which wall the pipes are on, and list what has to fit. This bathroom layout planner returns a scaled bathroom floor plan in about a minute — toilet, basin, shower and bath drawn at real sizes along one wet wall, every clearance held, and the door checked so it actually opens. Already have a plan? Upload it and change the bathroom on it instead.

A bathroom floor plan is a scaled overhead drawing of one bathroom showing the walls, the door and its swing, the window, and every fixture — toilet, basin, shower, bath — at its real size with the clear floor in front of it. This planner draws one, or redraws yours.
An existing bathroom plan, the bathroom on a full house plan, an architect's or agent's drawing, or a photo of a layout you sketched on paper with the measurements written on it. Say what should change and what has to stay exactly where it is — the walls and the plumbing wall are usually the parts you want untouched.
Examples
The input never changes: the same 5 x 8 ft full bathroom, bath across the end wall, toilet and vanity on the plumbing wall. What changes is the sentence underneath. Click any prompt to load it into the box above and run it on your own plan.
What FloorDrafter returns, depending on what you ask
The room size, where the door is and which wall the pipes are on is enough to draw from. These three ran on nothing but the text underneath them.
Three steps, about a minute. No account needed for the first plan, no software to install, and nothing to drag into place.
Type the bathroom dimensions, say which wall the door is on and which wall carries the drain, and list the fixtures that have to fit. Or upload an existing plan and say what should change on it.
A flat top-down plan for judging whether everything fits, a 2.5D overhead view for showing someone, or a 3D view for seeing the finished room with its tiling and fittings.
Check the clear floor in front of each fixture and the door swing on the drawing. Change one sentence — a wider vanity, a shower instead of the bath — and run it again until the layout works.
A bathroom is the most tightly regulated room in a house, and almost every layout that fails, fails on one of these four. Each has two figures: the code minimum you cannot go under, and the comfortable figure a designer holds to.
15 in / 380 mm min · 18 in / 460 mm better
Measured from the middle of the pan to any side wall, vanity or other fixture, on both sides. This is the most common failure in a narrow bathroom: the toilet gets pushed against the vanity and the room becomes unusable long before it becomes illegal.
21 in / 530 mm min · 30 in / 760 mm better
In front of the toilet, basin, bath and shower entry, measured as empty floor — not through another fixture. Two fixtures may share the same clear floor, which is exactly how a 5 x 8 ft bathroom works at all.
30 x 30 in / 760 x 760 mm min · 36 x 36 in / 900 x 900 mm better
Measured inside the finished walls, with at least 900 sq in / 0.58 m² of floor. Below 36 in a shower is legal but tight for a door swing, which is why a bath-to-shower swap usually ends up with a sliding or frameless panel.
Full swing radius · 28–32 in / 710–810 mm leaf
An inward door needs its whole quarter circle free of the toilet, the vanity and the bath. Where that will not fit — common under about 35 sq ft — the plan is drawn with the door swinging outwards, or as a pocket or sliding door, and says so.
Figures are the widely used North American planning numbers: the minimums follow the International Residential Code, the comfortable figures follow the NKBA planning guidelines. Local codes differ, and older properties are often below both. These are the same numbers the model plans to, so what the page says and what the drawing does are one set of rules.
Whether a fixture list fits is arithmetic, not taste: add the widths of everything that has to sit on the wet wall and compare that with the length of the wall. Six real footprints with that sum worked out, from the smallest legal half bath to a step-free wet room.
3 x 6 ft · 18 sq ft · 1.7 m²
Toilet on one 3 ft end wall, a 24 in wall-hung basin on the long wall by the door. The binding number is width, not area: a toilet needs a 30 in slot, so 36 in is the narrowest room that takes one. The 6 ft length gives the 21 in clear floor in front with room to spare.
5 x 7 ft · 35 sq ft · 3.3 m²
A 60 in bath fits the 5 ft end wall exactly. That leaves 52 in of side wall — not enough for a 30 in toilet slot and a vanity side by side, so they go on facing walls instead. The 60 in room width still leaves 39 in of clear floor between them.
5 x 8 ft · 40 sq ft · 3.7 m²
The most-built bathroom in North America, and it is not an accident. The bath takes the 5 ft end wall; the remaining 64 in of wet wall takes a 30 in toilet slot plus a 30 in vanity with 4 in to spare. It is the smallest room where all three fixtures line up on one wall.
6 x 8 ft · 48 sq ft · 4.5 m²
No bath, so the shower can be a proper 36 x 36 in rather than a 30 in squeeze. Along the 96 in wet wall: 36 in shower, 30 in toilet slot, 24 in vanity — 90 in used, 6 in spare. The extra foot of width over a 5 ft room is what buys the shower door its swing.
8 x 10 ft · 80 sq ft · 7.4 m²
The first size where a double vanity stops being a compromise. A 60 in double vanity plus a 30 in toilet slot is 90 in of the 120 in wet wall, leaving 30 in spare for a linen cupboard, with a 36 x 60 in walk-in shower and a freestanding bath on the other walls.
8 x 8 ft · 64 sq ft · 5.9 m²
Sized by the turning circle, not by the fixtures. A 60 in wheelchair circle plus a 36 in deep roll-in shower is 96 in — exactly 8 ft, which is why 8 x 8 is the practical floor. The 96 in wet wall takes the 60 in shower and a 30 in toilet slot with 6 in spare.
Fixtures come in a small number of standard sizes, and a plan is only useful if it is drawn to them. The third column is the phrasing to paste into your description so you get that size.
| Fixture | Standard size | What to write in your description |
|---|---|---|
| Toilet | 30 in / 760 mm wide slot, projects 27–30 in / 685–760 mm | "a toilet with 15 in from its centreline to the vanity" |
| Single vanity | 24–36 in / 610–900 mm wide, 21 in / 530 mm deep | "a 30 in vanity with a single basin" |
| Double vanity | 60–72 in / 1520–1830 mm wide, 21 in / 530 mm deep | "a 60 in double vanity with two basins" |
| Bathtub | 60 x 30–32 in / 1525 x 760–810 mm | "a 60 in bath across the end wall with a shower over it" |
| Shower (minimum) | 30 x 30 in / 760 x 760 mm, 900 sq in / 0.58 m² floor | "a 30 x 30 in corner shower" |
| Walk-in shower | 36 x 36 in to 36 x 60 in / 900 x 900 to 900 x 1525 mm | "a 36 x 60 in walk-in shower with a glass panel" |
| Clear floor in front | 21 in / 530 mm minimum, 30 in / 760 mm comfortable | "keep 21 in of clear floor in front of every fixture" |
| Door | 28–32 in / 710–810 mm leaf, 36 in / 900 mm for step-free | "the door is on the short wall and must swing clear" |
| Turning circle (step-free) | 60 in / 1525 mm diameter clear of every fixture | "keep a 60 in turning circle clear of all fixtures" |
Metric fixtures differ slightly — a 1700 mm bath is the European equivalent of the 60 in tub, and 1500 mm is the compact one. Write your sizes in whichever units you measured in; mixing feet and millimetres in one sentence is what causes a plan to come back at the wrong scale.
How each fixture is drawn on a plan, and what codes such as WC and LAV stand for, is set out in floor plan symbols and abbreviations
The order matters. These six are listed in the order they should appear in your sentence — the first three decide whether the plan is even about your room.
"A 5 ft x 8 ft bathroom" or "a bathroom of about 4 m²". Without it every clearance is guesswork, and the room comes back at whatever size makes the fixture list look good.
"The soil stack is on the long left-hand wall." This is the single most valuable sentence you can write and the one most people skip. Moving a toilet to another wall is the difference between a weekend job and lifting the floor.
"Door on the short wall, opening inwards." In a small bathroom the door swing eats more usable floor than any fixture, and it is the first thing that has to give when the list does not fit.
"A 60 in bath, a toilet, a 30 in vanity." Naming the widths keeps the drawing honest — an unsized fixture list gets drawn at whatever size happens to fit.
"Keep 30 in of clear floor in front of the toilet" or "keep a 60 in turning circle". Say it and it becomes a constraint the layout is checked against instead of a default.
"Large-format light grey tiles, chrome fittings." Useful on the 3D view and wasted on a flat plan — put it last so it never competes with the dimensions.
Every plan downloads as a high-resolution image. The three things people ask this bathroom design tool for most:
Download the drawing as a PNG and send it to your fitter, your plumber or your partner. It reads as a bathroom layout to anyone, without needing CAD software to open it.
Ask for dimension lines and the same layout comes back labelled — fixture widths, room size, and the clear floor in front of the toilet and basin. Useful for checking a quote against what you asked for.
Switch the view and the same layout is drawn as a 3D room with the ceiling removed, tiling and fittings shown. The layout does not change — same bathroom, different camera.
Most free bathroom planners are 3D room editors: you get an empty rectangle and a catalogue of fixtures to drag into it. They are good at showing you what a bathroom looks like. They are not good at telling you whether yours fits.

| Learning curve | Describe the room in plain words | A fixture library, snapping, layers and a camera to learn | None for you |
| Trying a second option | Change one sentence and run it again | Undo and re-drag every fixture | Another round of revisions |
| Good for | Deciding a layout, and testing whether it is legal and usable | Choosing tiles, finishes and fittings once the layout is settled | Structural changes, plumbing moves and permits |
Working out whether the bath can become a walk-in shower, or whether a double vanity fits, before ringing a fitter.
Under 40 sq ft every inch is a decision. Run the same room five ways and see which fixture list survives the clearances.
Turning a customer's phone photo of a scribbled layout into a drawing you can quote against or put in front of a client.
Checking a new bathroom or en-suite works on paper — and that the door still opens — before committing it to a build.
What people ask before they use the planner
Type the room size, say which wall the pipes are on, and list what has to fit. The layout comes back drawn to scale with the clearances held.
