Free 3D sauna designer
The SaunaDesignPro 3D sauna designer
Open the free 3D planner to size a sauna room, validate heater placement and clearances, compare wood and materials, and build an editable material list and construction submittal.
The designer is the interactive core of SaunaDesignPro. Set a footprint and dimensions, add doors, windows, benches, a heater, ceiling, and flooring, and see the room rebuild in 3D as you edit — framing, cladding, and the bill of materials all update together.
It runs in the browser with no account required to start. When the plan is right, export the material list and a build-ready submittal PDF.
What you can do in the designer
- Choose a square, L-shape, triangle, or beveled footprint and set live dimensions
- Place multiple doors, windows, and glass walls per wall
- Add benches and a heater, with clearances and bench heights checked automatically
- Compare Thermory and other cladding woods on the real 3D model
- Toggle interior cladding, air gap, foil, framing, and outdoor assembly layers
- Export an editable material list and a construction submittal PDF
Start from a template
You do not have to start from a blank room. Pick a complete build template close to your space — indoor conversion, outdoor cabin, or barrel — and adjust dimensions, openings, and materials from there.
