PRODUCT DESCRIPTION
The Finnleo Designer-B 6.0 kW is a wall-mounted electric sauna heater for medium-size traditional sauna rooms. Finnleo’s installation manual sizes the 6.0B for approximately 175 to 310 cubic feet.
Room size first
For a conventional insulated wood sauna room, the 6 kW Designer-B sits in the middle of the Designer-B range. Calculate your finished room volume, then adjust for glass, tile, stone, masonry, or other uninsulated surfaces before selecting the heater.
Recommended room volume: 175–310 cu. ft.
Why choose the Designer-B?
- Built-in controls: useful when you do not want or cannot use a separate wall-mounted controller.
- 9+1 timer: one-hour operating zone plus a delay-start range of up to nine hours, according to the Finnleo manual.
- Flexible control position: the control knobs can be located on the front or repositioned to either side before mounting.
- Wall-mounted footprint: leaves more usable floor area in the sauna room.
- 50-lb rock capacity: provides the stone mass for traditional sauna heat.
Electrical installation
The 6.0B is a permanently connected electric heater. Finnleo’s manual requires installation by a licensed electrician and provides model-specific wire, voltage, phase, and clearance requirements.
Do not size the heater by person count alone. Room volume and construction are more important.

FAQ
Can I finance my sauna purchase?
Yes! We offer easy monthly payments through our financing partners so you can enjoy your sauna today without paying in full upfront.
Do I need professional installation?
Installation requirements vary by product. Some 120V infrared saunas may use a dedicated household circuit, while many 240V saunas and heaters require professional electrical work. Always follow the manufacturer’s manual and local electrical and building codes. Contact Martin Sauna before ordering if you want the model-specific electrical or installation requirements.
What’s the warranty and return policy?
Manufacturer warranty coverage varies by brand, model, and component. Eligible Martin Sauna returns generally must be requested within 30 days of delivery and are subject to condition requirements, exclusions, return shipping, and possible restocking fees. Review our Return and Refund Policy and the applicable manufacturer warranty before ordering, or contact us for model-specific confirmation.
Infrared vs. Traditional Saunas – What’s the Difference?
Infrared saunas use infrared emitters and typically operate at lower air temperatures. Traditional saunas heat the room with an electric or wood-burning heater and sauna stones, creating the classic higher-temperature sauna experience. When the heater and manufacturer instructions allow it, water can be added to approved sauna stones for a brief increase in humidity.
Neither type is automatically better. The right choice depends on the heat experience you prefer, the installation, electrical requirements, and the specific model.
What does research say about sauna health benefits?
Sauna research includes encouraging findings, particularly around cardiovascular responses and long-term observational associations, but the strength of evidence varies by outcome. Sauna use should not be presented as a treatment, a substitute for exercise or medical care, or a guarantee against disease.
