The sauna exterior

We use Thermowood for all our external cladding, brushed to enhance the texture in the grain. A black natural oil is applied giving the sauna a beautiful finish which allows it to sit modestly into the landscape. Each of our saunas feature a welcoming entrance deck and finishing touches of coat & robe hooks.

The sauna interior

Internally the sauna features breathable and natural sheep's wool insulation with a slow grown larch vapour cavity, allowing for moisture management and ventilation. Thermo aspen panelling creates a beautiful wooden environment and helps regulate humidity, whilst being comfortable to the touch.

Staying seated & heated

Thermo aspen bench boards with integrated angled backrest for comfort. Finished with Stelon sauna oil, a wood barrier which is also naturally antibacterial. The Tyto Sauna seats up to 3 people comfortably.

Light levels, at the right levels

Brighter mornings and toned-down eves. Set your mood with adjustable Internal 3000k LED lighting, lined below benches and above backrest. Illuminating the outside decking are Astro LED wall-mounted black downlights.

Flooring built for busy

Choose between light or dark grey high traffic porcelain tiles with concrete effect.

Window into nature

Large high temperature sealed double glazed windows bring an intimate level of connection to the surrounding landscape, as you bathe in the sauna experience.

We couldn't be more thrilled with our Tyto. The workmanship and attention to detail are excellent. It was a pleasure to work with Out of the Valley too. Highly recommend!

Out of the Valley's understanding of form, materials and texture and how a sustainably built space can integrate into the natural environment, to create something of beauty, is to be admired. It’s not just what these saunas look like, it’s how they feel...
