NOOK Sauna · for 4-5 people
Your own sauna ritual, down the garden
80 °C in 30–40 minutes, an outdoor shower and a window onto the view
Heat, cold, quiet
For your guests
A hotel spa, booked by the session
The sauna is the centre; the NOOKs build the circuit around it.
HUUM · 80 °C in 30-40 min · up to 100 °C · 5.69 m² · 4-5 people · covered vestibule with shower
Sauna, cold plunge and somewhere to sit afterwards, on your own grounds. A NOOK 10 or a NOOK 20 alongside becomes the massage or treatment cabin, the yoga room or the quiet room. Start with one sauna and grow on evidence.

Frequently asked questions
How much does a NOOK outdoor sauna cost?
From €39,000, excluding VAT: the finished NOOK Sauna, ex works.
It comes with a HUUM electric heater, a hemlock interior with LED lighting and a covered outdoor vestibule with a shower. Transport, foundations and installation are quoted for your address, and we organise all three.
How long does a NOOK outdoor sauna take to heat up, and what heater does it use?
80 °C in 30–40 minutes, and up to 100 °C, with a HUUM electric heater.
Being electric, there is no wood to load.
How many people fit in a NOOK outdoor sauna?
4 to 5 people, in a 5.69 m² sauna room.
The unit measures 4 × 2.50 m and includes a covered outdoor vestibule with a shower, floored in Millboard composite.
Do I need planning permission for an outdoor sauna?
It depends on where you are and how you'll use it.
NOOK Sauna sits on screw piles rather than permanent foundations and can be lifted out and moved, which often helps. We look at it with you before you commit to anything, and where planning consent is needed, that comes first.
How long does a NOOK outdoor sauna take to build and install?
It is built in 8–12 weeks, arrives finished and is connected in hours.
Foundations are done beforehand, on a separate visit: screw piles, your existing level concrete base or concrete pads.
Can you use an outdoor sauna in winter?
Yes, all year. The outdoor vestibule is covered, with a shower and a Millboard composite floor.
The sauna room has a glazed window onto the view. Add a cold plunge or a hot tub if you like: heat, cold, and doing nothing afterwards.
What timber is a NOOK outdoor sauna made from, inside and out?
Inside, hemlock with LED lighting, with cedar as an option. Outside, thermo-treated timber in black or oak, or Millboard composite.
The sauna room has a glazed window onto the view.
Can a NOOK outdoor sauna be part of a spa circuit at a hotel or glamping site?
Yes. It works as a private sauna or as part of a spa circuit with a cold plunge or hot tub.
A NOOK 10 or NOOK 20 alongside can be the massage cabin, the yoga room or the quiet room: the sauna is the centre and the NOOKs build the circuit around it. Model it with your own numbers: we don't give income forecasts.
How much is the deposit to reserve a NOOK outdoor sauna?
€2,000 (or the equivalent in pounds or dollars), refundable if your site turns out to be unviable.
You then complete 30% to secure your production slot, and pay the remaining 70% when production starts.
What guarantee comes with a NOOK outdoor sauna?
A 3-year guarantee on residential units, plus each component's own manufacturer warranty. Hospitality guarantees are tailored to each project.
