CLIFF Mini electric sauna heater

Electric sauna heaters

  • Environmentally conscious design
  • Mild and long-lasting steam
  • Control with mobile app
  • Warranty 5 years


CLIFF Mini electric sauna heater is a slimmer, wall-mounted version of the award-winning CLIFF heater. Inspired by northern coastal cliffs, this heater catches the eye with its stone-emphasized design. What makes both CLIFF heaters unique is their innovative and eco-friendly construction. The ribs of CLIFF heaters are created from cutouts generated during the production of STEEL electric heaters. This eliminates material waste and allows two heaters to be made from the same stainless steel sheet. Despite its slender form, CLIFF Mini can hold plenty of heating stones, providing a mild and long-lasting steam experience. The built-in air tunnel ensures fast heating. With a safety distance of only 6 cm from the walls, CLIFF Mini is easy to place even in smaller home saunas.
