Designer wellness in the garden: a sauna garden shed with panoramic glazing

Black-Box Sauna – Designer wellness with panoramic glazing

The Black Box Sauna is our wellness statement for the garden: on the outside, a deep, dark, tranquil cube; on the inside, a warm retreat with a view of the greenery. This sauna garden pavilion with panoramic glazing demonstrates just how striking the contrast is – the dark exterior makes the surroundings glow, whilst the large pane brings the garden into the sauna room. Designer wellness that gets you excited even from the terrace.

Bio sauna heater: Finnish or gentle – the choice is yours

The centrepiece inside is the bio sauna heater. It offers flexibility in choosing your sauna session: classic Finnish-style with dry heat – or a gentler steam sauna session with a lower temperature and higher humidity. This way, the sauna adapts to how you feel on the day, not the other way round – and even guests who find 90 degrees too much will find it to their liking.

Light as a design element: RGB LEDs and indirect lighting

A special feature of the interior design is the integrated RGB LED lighting in the backrests, as well as the indirect downward lighting, which creates an atmospheric ambience in the relaxation area. The lighting can be adjusted to suit the mood – from a warm candlelit tone to a cool blue – and turns an evening sauna session into an experience without causing any glare.

The black cladding: HPL for continuous use

The outer cladding, made from Trespa HPL composite panels, is specifically designed for long-term outdoor use and withstands moisture and temperature fluctuations with ease – no small matter for a sauna where temperatures can reach 90 degrees inside whilst it’s freezing outside. The sauna garden house retains its shape and colour for years without any maintenance required for the façade: no painting, no oiling, no further treatment. It is estimated to have a lifespan of around 50 years.

Panoramic glazing: enjoy a sauna with a view

The generous glazing is what sets this apart from a standard sweat cabin and makes it a true wellness room: instead of looking at wooden walls, you gaze out into your own garden – at lush greenery in summer and snow-covered branches in winter. Our reference project, a black outdoor sauna made from HPL, demonstrates how the design looks in pure black with a panoramic pane.

The DESIGA garden sauna

Our garden sauna is developed in-house and manufactured in Germany – the structure, glazing and sauna technology are all coordinated from a single source. For the exterior cladding, you can choose from over 250 HPL colours and finishes; we’ll send free colour samples to your home. We deliver throughout Europe, and our team takes care of the installation. Over 2,000 completed projects and a 5-star rating from more than 220 Google reviews speak to the care we take.
