Sauna Heater Size Calculator
Estimate raw and adjusted room volume, then compare it with current manufacturer heater ranges.
Open tool →Technical sauna research
Choose the sauna that fits the room, circuit and real project.
SaunaVerdicts focuses on the numbers that decide whether a home sauna works: voltage, amperage, heater kW, room volume, dimensions, weight, clearances, operating cost and manufacturer-backed specifications.
Decision tools
Plan before you buy.
Use the calculators for shortlisting and budgeting. Final electrical work and heater installation must follow the exact manufacturer manual and local code.
