Is the heater included in the pre -cut sauna kits?

Hello Peggy and thank you for your inquiry. We sell the room kits with or without the sauna heater. Below the main picture on the product page, there are five tabs. Click the one title HEATER where you can view the information on the heater models. Heater selection and pricing is further down the page in the right column. Less expensive versions of the Tylo heaters have controls on the heater. More expensive versions have digital controls that mount outside the sauna room.
