Holl's Onyxia 240 Panorama Canopy Black outdoor steam sauna

Holl's Onyxia 240 Panorama Canopy Black outdoor sauna

The Holl's Onyxia 240 Panorama Canopy Black is an outdoor barrel sauna designed to create a refined wellness area with technical wood, a carefully finished exterior and a traditional steam sauna experience. Its cylindrical shape, black outdoor finish and half-moon rear window give it an elegant presence on terraces, in gardens and in open-air wellness spaces.

With capacity for up to 6 seated users or 2 lying down, this model offers a comfortable interior layout with two facing benches. This configuration is suitable for shared sessions and makes efficient use of the interior volume while preserving the enveloping atmosphere associated with barrel saunas.

ThermoWood® exterior with black finish

The structure is made from ThermoWood® wood / ThermoWood® treated pine, a material treated at high temperature to improve its stability and performance in outdoor installations. This type of wood is known for its durability, dimensional stability and warm appearance, making it especially suitable for outdoor wellness projects.

The exterior features a black waterproof paint for outdoor use, enhancing its contemporary style and allowing a discreet visual integration in modern environments. The result is an outdoor sauna with a distinctive look, created for spaces where design and functionality are equally important.

Panoramic rear window and tempered glass door

The Onyxia 240 Panorama Canopy Black includes a half-moon semicircular rear glass window, a detail that brings natural light into the cabin and increases the visual sense of space without losing the intimate feel of the sauna. This rear opening is one of the most recognisable features of the Onyxia range.

Access is through an 8 mm tempered glass door, a robust element suited to wellness use. The combination of treated wood, glass and black finish creates a balanced aesthetic between traditional sauna design and a contemporary architectural style.

Interior with facing benches for 6 seats

The interior is arranged with two deep facing benches, a layout suitable for shared sessions and a comfortable atmosphere. The stated capacity is 6 seated places or 2 lying places, depending on how the interior space is used.

The bench installation height is approximately 52 cm, while the backrest is positioned approximately 20 cm above the bench. These details help when planning interior ergonomics and assembly.

Steam technology and heater compatibility

This model is designed as a steam sauna. It is compatible with a 6 to 8 kW electric heater or a wood-burning stove, allowing the installation to be adapted to the desired experience and project requirements. For installation with a wood-burning stove, compatibility with Harvia is indicated.

An electric heater configuration supports practical integration in wellness spaces, while the wood-burning option is intended for those who prefer a more traditional sauna experience. The heater is not specified as included in the available data, so it should be selected according to the planned installation.

Outdoor installation and recommended base

As an outdoor sauna, correct base preparation is essential. The sauna must be firmly anchored to the base or foundation by the customer. A foundation slab or strip foundation is recommended, with a stable, level surface suitable for assembly.

Before installation, it is advisable to plan the location, access points, electrical supply if an electric heater is used, and the specific requirements if a wood-burning stove is selected. In professional projects or intensive-use spaces, this planning helps ensure an orderly assembly and a visually coherent integration with the surroundings.
