A photo tool shows you the style, but only a measured planner tells you if the shower actually fits. Here's how to plan a bathroom layout that works, the clearances the apps don't check, and the best free planners.
A photo restyler will show you a gorgeous spa bathroom, but it won't tell you whether the freestanding tub you fell for actually leaves room to open the door. That's a different question, and it needs a different tool: a layout planner that works to scale. If your remodel involves moving anything — the shower, the vanity, the toilet — or you're just trying to make a tight room work, this is where you start. Here's how to plan a bathroom layout properly, including the clearances most apps quietly leave you to figure out yourself.
A layout planner lets you draw your bathroom's floor plan to scale, then drag fixtures — toilet, shower, tub, vanity — into place and see whether they fit. The good ones show automatic measurements as you go, so you catch a too-tight gap on screen rather than on demolition day. Most give you a 2D plan (for getting the layout right) and a 3D view (for getting a feel for the finished space).
The key word is to scale. Unlike a photo tool, a planner deals in real dimensions. If there's 700mm between the tub and the vanity on your plan, there's 700mm in real life — which means you can actually test whether a layout works before anyone lifts a tool.
This is the step that makes or breaks the whole thing, and it's tempting to skip. Before you place a single fixture, measure your real bathroom:
Enter those into the planner so your digital room matches the real one. The plumbing locations matter more than people expect, because that's the thing you build around — relocating a drain is one of the most expensive moves in a bathroom, so knowing where they are shapes every good layout.
Here's what most planners won't stop you from doing: designing a layout that's technically drawn but uncomfortable or non-compliant. The apps let you place fixtures anywhere; they don't enforce the clearances a real bathroom needs. So keep these rough targets in mind as you plan:
That last one catches people constantly. If the door swing collides with your layout, consider re-hanging it to open outward, or fitting a sliding or pocket door — a change a planner lets you test in seconds but won't suggest on its own.
Planner 5D is the most beginner-friendly. You draw the floor plan, drag in fixtures from a catalog, and flip between 2D and 3D with automatic measurements. The core layout tools are free; some advanced objects need a paid plan. Good for homeowners who want to test ideas without a learning curve.
RoomSketcher has a solid free tier for creating floor plan projects and basic 3D viewing, with higher-quality plan exports behind an upgrade. Its AI Convert feature can even turn an existing blueprint into an editable plan.
Free browser planners (like Free Room Planner and similar) let you enter dimensions, drag fixtures to scale, snap to walls, and export or share the plan with your fitter — no download, no account. Perfect for a quick, precise test of whether a layout fits.

A layout planner tells you what fits, not what's possible or affordable. You can draw the toilet on the opposite wall, but the planner won't tell you that moving the drain there means tearing up the floor and adds thousands to the job. It also doesn't handle the parts of building regulations that touch bathrooms — electrical zones around water, ventilation, drainage falls. Those are real, and they're a contractor's and sometimes a building inspector's domain.
So the honest workflow is: use a planner to prove a layout fits and feels right, then take it to a professional who can tell you what it costs to actually build and whether it meets code. The planner saves you from designing something that doesn't fit; the contractor saves you from building something that doesn't work.
Putting it together: use a photo tool to decide the style, a layout planner (this) to confirm the fixtures fit, and a cost estimator or contractor quote to price it. Three quick tools, each answering its own question, and you walk into the remodel knowing what you want, that it fits, and roughly what it costs. That's the difference between a smooth renovation and an expensive mid-project surprise.
