Most renovation projects start the same way. A rough sketch on the back of an envelope. A voice note. A long text describing what you want. Your contractor nods, starts work, and three days in — something doesn't fit. A cabinet blocks the oven door. The bath door swings into the toilet. Fixing it costs time and money that was never in the budget.
A free, browser-based planner removes that friction before work begins. No sign-up. No download. No learning curve. Just an accurate floor plan you can share before a single tile is lifted.

- Export your plan as a clean PNG and share it before quoting begins.
- No cost, no account, no download required.
Why does renovation planning need more than a sketch?
Renovation planning needs more than a sketch because contractors quote from what you give them — and a vague brief means a padded quote. If your dimensions are guesses, that buffer for the unknown comes straight out of your budget.
Measurement errors are the most common culprit. A kitchen that reads 3.2 metres wide on paper might only offer 2.9 metres of usable wall once you account for a radiator, a door swing, and a window reveal. Miss those, and your cabinet order lands wrong.
Furniture fit is the other trap. A dining table that looks fine in a showroom can block a walkway or a patio door at home. Graph paper helps, but it's slow, imprecise, and awkward to share. A digital floor plan with live measurements — where every element snaps to a grid — catches these problems in minutes, not after installation.
What to look for in a room planner app for renovations
Not every floor plan tool is built for renovation work. Many aim at decorators picking paint colours or staging a home for sale. Renovation planning has different needs: accuracy matters more than looks, and the output has to be usable by a fitter or builder — not just pretty on a mood board.
Three features actually matter.
Snap-to-grid accuracy
When you're planning around fixed plumbing, a load-bearing wall, or a doorway that can't move, precision is everything. A tool that snaps walls and fixtures to a 10cm grid means every measurement you share is real — not an approximation.
Say your bathroom's soil pipe sits 400mm from the back wall. You need to place the toilet at exactly that distance on the plan. Grid-snapping makes that simple. Freehand drawing tools don't.
Exportable plans a contractor can use
A plan that only lives on your screen is half useful. The best room planner apps export your layout as a clean image — a PNG you attach to an email, drop into a message, or print for a site meeting.
Fitters and builders lean on these exports during quoting and installation. A labelled floor plan with real dimensions cuts back-and-forth, reduces scope creep, and gives everyone one shared reference from day one.
No sign-up, no cost, no software to install
This matters more than it sounds. Friction — creating an account, entering a card, installing an app — pushes people to abandon tools before they get any value. For renovation planning, that means falling back on sketches. Which means miscommunication. Which means expensive surprises.
Free floor plan software with no download and no account removes every barrier. You open it, draw your room, and share the result. That's the whole workflow. Some people reach for a general design tool like a Canva floor plan maker, but those lean toward visuals over dimension accuracy — the opposite of what a renovation needs.
How do you use a free room planner for a kitchen renovation?
Use a free room planner for a kitchen by measuring your walls, drawing them to scale, placing fixed elements first, then arranging units around them and checking clearances before you export and share. Kitchens are the most complex room most homeowners tackle.
Follow these steps:
- Measure every wall — include windows, doors, and fixed obstacles like boilers or soil pipes. Write it all down before you open the tool.
- Draw your walls, entering exact dimensions as you go. Each wall snaps to the 10cm grid.
- Add fixed elements first — the sink (fixed by plumbing), the hob (fixed by gas or power), and the fridge.
- Place cabinets and worktops around them, keeping at least 1 metre between facing units for comfortable use.
- Check door swings so the oven, dishwasher, and tall units open fully without clashing.
Export your plan as a PNG and send it to your fitter before quoting begins. For a deeper walkthrough, see our step-by-step kitchen renovation guide.
How do you use a free room planner for a bathroom renovation?
Use a free room planner for a bathroom by mapping the soil pipe and waste outlets first, then placing the toilet, bath, and basin around them while checking door clearance. Bathrooms have the least floor space and the most fixed constraints of any room.
Get a fixture wrong on a plan and you're paying a plumber to reroute pipework — a bill that often runs into several hundred pounds.
- Measure precisely — note the soil pipe, existing waste outlets, and the window.
- Draw the room outline and mark where the door opens.
- Place the toilet first, aligned to the soil pipe, and check the door doesn't swing into it.
- Add the shower or bath, confirming clearance on all sides (a minimum of 700mm in front of a shower door is a common guideline).
- Position the basin and confirm the door still opens fully.
Export and send to your bathroom fitter before they quote. Our free bathroom layout planner covers awkward spaces and fixture-specific spacing in more detail.
How do you share a renovation plan with a contractor?
Share a renovation plan with a contractor by exporting your floor plan as a PNG image, then attaching it to an email, sending it via message, or printing it for an in-person meeting. Clear dimensions on the image do most of the work.
Include a few things alongside the plan:
- Key dimensions — overall room size, plus critical measurements like the distance from a window to a corner.
- Fixed points — where plumbing, gas, and electrical connections currently sit.
- Material notes — tile sizes, unit finish, or flooring type if you've chosen them.
- What you're not changing — if the window stays, say so, so the contractor quotes only for the real scope.
A plan with these details usually returns a tighter quote and fewer questions mid-job.
Which renovation mistakes does a room planner prevent?
A room planner prevents the fit-and-clearance mistakes that surface after ordering — blocked doors, tight walkways, and units that don't fit the wall. These aren't edge cases; they happen on real projects every week.
- Islands that block the oven door. Kitchen islands need at least 1 metre of clearance on every working side.
- Baths placed where the door won't open. A standard door needs roughly 700mm of clear swing.
- Radiators ignored on the plan. A radiator can stop you running base units the full length of a wall — obvious on a plan, invisible in your head.
- Appliance depth overlooked. Fridge-freezers and washing machines protrude past the cabinet line and can block drawers.
- Misread proportions. Empty rooms always look bigger. Furniture placed to scale shows how much floor you actually keep.
Learning how to draw floor plans accurately is the single best way to avoid all five. Planning a wider project? Our home office layout guide shows how the same workflow applies room by room.
Start planning your renovation — no sign-up needed

Free Room Planner gives you a browser-based tool with snap-to-grid accuracy, live measurements, and clean PNG export. It covers kitchens, bathrooms, bedrooms, and living rooms. No account to create, nothing to install, and no cost — ever.
Draw your layout, export it, and share it before the first quote lands. Your contractor will thank you for it.
Frequently Asked Questions
Quick answers to the questions homeowners ask most about planning a renovation layout.
Is a free room planner accurate enough for a contractor?
Yes. A tool with snap-to-grid accuracy and live measurements produces dimensions a fitter or builder can quote from directly. Every wall and fixture aligns to a 10cm grid, so the measurements you share match the real room rather than a rough estimate.
Do I need to download software to plan a room?
No. Free Room Planner runs entirely in your browser, so there's nothing to install and nothing to update. You open the page, draw your layout, and export it — the same on a laptop, tablet, or phone.
What file format should I send my contractor?
Send a clean PNG image. It opens on any device without special software, attaches easily to email or messages, and prints clearly for site meetings. Include the key dimensions and fixed points alongside it for the tightest quote.
Can I plan more than one room?
Yes. You can plan kitchens, bathrooms, bedrooms, and living rooms, or map several connected spaces in one multi-room layout. That's useful for larger renovations where flow between rooms matters as much as each room on its own.
How long does it take to draw a renovation plan?
Most single rooms take under 10 minutes once you have your measurements written down. The slow part is measuring the real space accurately — so do that first, then drawing and exporting the plan is quick.
