1 review for 2 – 4 Person Barrel Sauna W20

  1. Jonathan Mocatta

    Thank you Sigmar for all your help building my beautiful 4 person barrel sauna. Thank you for being so available and patient with me during the process. Thanks to you I saved thousands not having to hire a builder. I live at 10,000 feet in Colorado and this sauna rocks. I went for the electric heater option. It takes about 45 minutes to get to 194 degrees. The quality of this BZB product is outstanding and easily accommodates my family of 5. Highly recommend buying from Sigmar.
