Best Features - Deep-Rock Ultimate Sauna Heater ...

  • You can chose to have more rocks - use any one of the 3 adjustable levels for sauna rocks so the sauna user who likes to have lots of rocks in the heater can select 22#, 35# or up to 50# of rock. Advantage of the rocks is to create a "gentler" heat.

  • The elements are low-density longer-lasting elements that can withstand the shock of water thrown on the elements. These elements are a superior grade to the normal stainless steel elements used in other sauna heaters.

  • The use of surgical-grade stainless-steel eliminates off-gassing from metal or painted parts inside the sauna heater. Saunas are to help us detox. Read more: The Health Benefit of a 100% Stainless-Steel Sauna Heater.

Use of Water on the Hot Sauna Rocks ...

Or you can use the Deep Rock "DR" heater as a dry sauna heater with no water added to the rocks. Read more: The Importance of Humidity for Health and Sauna Enjoyment.

Health Benefits of a Stainless Steel Sauna Heater ...

Deep-Rock "DR" sauna heaters are made entirely from surgical grade stainless steel that does not off-gas or release any trace toxins when the heater is in use. Painted parts or galvanizing, a coating process that uses the heavy metals tin, zinc and lead to prevent rusting, are used in some sauna heaters to reduce cost. There are no painted or galvanized parts in a Deep Rock "DR"sauna heater.

All painted, galvanized
and aluminum parts have been eliminated by the use of stainless-steel components in the Deep Rock "DR" Sauna Heater.
Medical experts highly recommend the Deep-Rock "DR" sauna heaters for people who have sensitivities, have experienced allergies or for those who may develop sensitivities in the future.
