The Harvia The Wall SWS80 is an 8kW wall-mounted electric sauna heater for rooms up to 424 cubic feet, finished in stainless steel. It is the stainless steel, 8kW model in the Harvia The Wall series - a heater defined by its ultra-thin wall-mounted profile and built-in digital controls. This listing is the heater only. Sauna stones are sold separately. The SWS80 has integrated digital controls built into the heater face and does not require a separate external Xenio or Fenix control unit for basic operation - this is the key distinction between the SWS series (built-in controls) and the SW series (which requires an external Xenio or Fenix control). For buyers who want to add WiFi and app control to the SWS80, the CX004WIFI or FX001XW panel can be added separately.
The Wall design - ultra-thin profile, architectural heater
Harvia The Wall series is designed to be as architecturally minimal as an electric sauna heater can be. The heater mounts directly to the sauna wall with a very shallow depth profile, presenting an almost flat surface to the sauna room. From the bather's perspective, the heater reads less as a freestanding or projecting appliance and more as a panel integrated into the wall surface - the sauna stones are visible in the shallow basket, and the stainless steel face and controls are flush with the wall plane. For sauna rooms where the visual priority is minimalism and unobstructed bench space, The Wall's ultra-thin format achieves what no conventional compact floor-standing or projecting wall-mounted heater can match. The SWS80 stainless steel finish suits contemporary sauna rooms with brushed metal hardware, lighter wood tones, and clean-lined modern interiors.
Built-in controls - no external Xenio required for the SWS series
The SWS series (SWS60, SWS80) has integrated digital time and temperature controls built into the heater face. No separate Xenio CX30 or CX45 control unit purchase is required to operate the heater - the controls are present and functional on the heater itself. This is a meaningful difference from the SW series (SW60, SW80), which requires an external Xenio or Fenix control for operation. For buyers who want a complete, self-contained The Wall installation without a separate control purchase, the SWS80 is the appropriate choice. For buyers who want WiFi and MyHarvia or MyHarvia 2 app connectivity, the CX004WIFI Xenio WiFi panel or the FX001XW Fenix WiFi panel can be added to the SWS80 to enable app control without replacing the heater.
8kW stainless - the larger SWS output in the brighter finish
The Wall series covers two output levels: 6kW (SWS60/SW60, up to 318 cu ft) and 8kW (SWS80/SW80, up to 424 cu ft). The SWS80 at 8kW is the larger of the two and is available in stainless steel (SWS80, this listing) and black (SW80). The stainless finish is the lighter, brighter option - appropriate for sauna rooms where the lighter reflective surface of stainless complements the interior rather than the darker, more recessive look of the black finish. All technical specifications are identical between the stainless and black 8kW models. Sauna stones are sold separately for both finishes.

Harvia The Wall SWS80 8kW wall-mounted heater - stainless steel
Installation and operation manual
Required (not included): Sauna stones - see Stone Requirements document for correct specification and quantity. Optional (sold separately): CX004WIFI or FX001XW WiFi panel for app control. A licensed electrician is required for all electrical connections. Do not connect to a GFI/GFCI breaker.
Why the Harvia The Wall SWS80 stands out
Ultra-thin profile - the most minimal wall-mounted heater
The Wall's defining characteristic is its shallow depth profile - it mounts to the sauna wall and presents an almost flat surface to the room. Compared to conventional wall-mounted heaters that project significantly into the sauna space, The Wall minimises the visual and physical intrusion of the heater, keeping bench space clear and the room geometry uninterrupted. The stainless steel face of the SWS80 complements lighter interior material palettes.
Built-in controls - complete without a separate purchase
The SWS80 operates with its built-in digital time and temperature controls from the moment it is installed and connected by a licensed electrician, without a separate Xenio or Fenix control unit purchase. For buyers who want a clean, self-contained installation without additional control hardware, the SWS80 delivers a complete working heater in a single purchase - plus the stone purchase.
8kW for rooms up to 424 cu ft
The SWS80 covers rooms up to 424 cubic feet - the largest room range in The Wall series. For mid-size home sauna rooms where the SWS60's 318 cu ft ceiling is insufficient, the SWS80 is the correct step up within the same ultra-thin wall format. Both 6kW and 8kW share the same architectural heater profile; only the output and room range change between them.
Stainless steel - the lighter Wall finish
The SWS80 stainless steel finish is the lighter, brighter option in The Wall 8kW range - the black SW80 (external control) and its black variants are the darker alternative. For sauna rooms with lighter wood species, white or grey tile, brushed metal hardware, or contemporary Scandinavian interiors where the heater should read as a bright neutral accent, the stainless SWS80 is the appropriate finish choice.
WiFi upgrade path - add CX004WIFI or FX001XW
If WiFi app control is wanted after installation, the CX004WIFI Xenio WiFi panel or the FX001XW Fenix WiFi panel (both sold separately at BathingBrands) can be added to the SWS80 to enable MyHarvia or MyHarvia 2 app control - remote preheat, scheduling, and temperature monitoring - without replacing the heater or its built-in controls. The FX001XW adds a 4.3" touchscreen and smart timer as additional upgrades.
ETL Listed - made in Finland
The SWS80 is ETL Listed for safety compliance and manufactured in Finland by Harvia, which has been producing sauna equipment for over 70 years. Harvia's Finnish manufacturing pedigree and the ETL certification provide confidence in the heater's quality and compliance for North American residential and commercial sauna installations.

The Wall SWS80 vs SW80 - built-in vs external control
SWS80 (this listing) vs SW80 - which is the right The Wall 8kW?
Both the SWS80 and SW80 are 8kW stainless steel The Wall heaters for rooms up to 424 cubic feet with the same ultra-thin wall profile and identical stone requirements. The difference is control configuration. The SWS80 (this listing) has built-in digital time and temperature controls - it operates without any additional control purchase, and WiFi can be added later with the CX004WIFI or FX001XW if wanted. The SW80 has no built-in controls and requires an external Xenio CX30 or Fenix FX30 control unit from the start. For buyers who want to keep the initial purchase simple with full built-in functionality, the SWS80 is the correct choice. For buyers who want the full Xenio or Fenix WiFi system with remote preheat built in from day one, the SW80 paired with a CX30-U1-U3-XW or FX30-U1-U3-XC is the appropriate configuration. Black finish variants (SW60B and SW80B) are available separately. A licensed electrician is required. Do not connect to a GFI/GFCI breaker.
