A 4kW sauna heater is perfect for small home saunas, typically suitable for spaces up to 250 cubic feet. To give you an idea, a 250 cubic feet sauna would measure approximately 6’x6’x7’ or 8’x5’x7’. Estimating the size of your sauna can sometimes be tricky, which is why we recommend using our sauna heater size calculator to help you choose the ideal model for your space.
If your sauna size falls between two categories, it's always a good idea to opt for the larger heater to ensure optimal heating performance and comfort.
