Outdoor hot tub with acrylic liner and integrated heaterv

Nordic Ember is an outdoor hot tub with square construction and an integrated heater, designed for year-round operation in exterior conditions. Dimensions of 245 × 245 cm and a capacity of 5 persons (4 seated positions, 1 reclined position) allow use within private wellness zones at residential and recreational properties.

A water volume of 1,700–2,100 litres, a depth of 95 cm and an overall height of 105 cm define the operational parameters of the tub.

Construction and material solution

The interior is formed by an acrylic liner in marble imitation (white or black), providing a smooth surface with high resistance to chemical and mechanical stress. The acrylic material simplifies maintenance and extends the operational service life.

The base is made of impregnated and painted wood, ensuring construction stability during long-term contact with moisture in exterior conditions. Water drainage is provided by a 1″ valve.

Exterior cladding

The exterior cladding of the tub is available in five material variants — spruce wood, thermowood, thermo tripple, WPC plastic or burnt wood. The cladding selection allows material unification with other exterior elements without compromising construction parameters.

Thermal dynamics

The integrated heater brings the full water volume to operating temperature within a 3–4 hour interval. The square footprint minimises surface thermal losses compared to circular constructions of equivalent volume.

Custom hot tub for various exterior environments

Nordic Ember is a custom hot tub designed as part of long-term exterior wellness infrastructure. The combination of the acrylic liner, wooden construction elements and integrated heater creates a functional unit for systematic regeneration through thermal hydrotherapy.

The model is intended for clients seeking an outdoor hot tub with an integrated heater, stable construction and an emphasis on long-term operation.
