About Build a Sauna
Build a Sauna helps you plan, visualise, and estimate your outdoor sauna project — from the first sketch to a verified material list.
What is Build a Sauna?
Build a Sauna is a free web-based sauna planning tool. It generates a live 3D model of your sauna, calculates structural dimensions, produces a material takeoff with cut lists, and provides baseline safety guidance rooted in Swedish building standards (BBR).
How it works
- Choose a sauna shape — rectangular, barrel, or two-room.
- Set dimensions, heating type, openings, and site conditions.
- Review the auto-generated material list, price estimate, and build plan.
- Export a PDF or share your design with a link.
Who is behind this?
Build a Sauna is an independent project built by a small team passionate about making sauna planning accessible. The tool grew out of a personal need: planning a backyard sauna without expensive consulting or CAD software.
Important disclaimer
Our sauna planner provides planning output and baseline assumptions — not certified construction documents. Always verify structural, electrical, fire-safety, and permit requirements with local professionals before building.
