Description
Holl’s Combi 4 Person Infrared Dual Heat Hybrid Steam Sauna
The Holl’s Combi 4 Person Infrared Dual Heat Hybrid Steam Sauna combines full-spectrum infrared heating with a powerful traditional Harvia sauna heater, providing two different sauna heating technologies within one spacious indoor cabin.
Designed for up to four people, the sauna is constructed from Canadian Spruce and Red Cedar and features large glass panels for an open, modern appearance. Comfortable bench seating, soft LED lighting and intuitive digital controls complete the cabin design.
Dual Heating System
The Holl’s Combi features both full-spectrum infrared heating and traditional Finnish sauna heat.
The infrared system uses eight quartz and magnesium infrared emitters together with one carbon floor panel. The system provides full-spectrum IR heat, including IR-A and IR-B, with comfortable infrared sessions between 40°C and 60°C.
For traditional sauna heat, the cabin includes a 4.5kW Harvia sauna heater with sauna stones. This provides high-temperature Finnish sauna heat with the option to create steam bursts using the stones.
The two systems give you the flexibility to switch between infrared and steam modes or combine both heating systems.
Premium Wooden Sauna Cabin
The sauna is built from Canadian Spruce and Red Cedar and features a natural wood finish alongside large glass panels.
The spacious interior provides comfortable bench seating for up to four adults, while the cabin is designed to provide even heat distribution when using either heating mode.
Soft LED lighting and digital controls are also integrated into the cabin.

Infrared sessions can be enjoyed at temperatures between 40°C and 60°C.
4.5kW Harvia Traditional Sauna Heater
The Holl’s Combi includes a 4.5kW Harvia traditional sauna heater.
Sauna stones are included, allowing the heater to provide traditional Finnish sauna heat and steam.
The heater requires a 230–240V single-phase supply with an approximate load of 18–20 amps, depending on voltage.
Electrical Requirements
This sauna requires a hard-wired electrical installation carried out by a qualified, certified electrician.
UK domestic electrical requirements are:
- 230V / 240V
- Single Phase
- 50Hz
The sauna must not be plugged into a standard socket.
The Harvia 4.5kW heater requires a dedicated hard-wired circuit, a 2-pole isolator switch outside the sauna, appropriately rated MCB and RCD protection, and correctly sized cabling determined by the electrician.
The infrared heating system has an approximate load of 2.8kW / 12 amps and is connected through the sauna control panel. It must also be RCD protected and installed according to the manufacturer’s wiring diagram.
All electrical installation must comply with BS 7671 UK Wiring Regulations.
