Extensible Family Sauna


The Finnish sauna for small homes

Now, you can build a Finnish sauna in your home even if you have limited space.


The Family Extensible Sauna is the new Finnish sauna for private homes and for anyone who has limited space. Ideal for domestic use, the sauna is designed to be closed when not in use.

Founded in 1980, Stenal specialises in SPAs and Wellness Centres in Italy and around the world and produces saunas, steam baths, relaxing solutions, and experience showers, all rigorously made in Italy.
The use of the latest technology and constant strive for improvement are essential to us. Stenal’s latest addition is the Family Extensible Sauna range, for domestic use, available in two versions: the 4 kW Family L and the 3 kW Family S. Finnish saunas for domestic use with a unique characteristic: they can be closed to take up less space.
Family Sauna is conceived to bring a Finnish sauna Made in Italy into your home.
Materials have been carefully selected: the cabin walls are made of natural smooth Spruce panels, 54mm thick, while the benches are made of Ayous wood. Family Sauna has a transparent, tempered glass door – 70x199 cm and 8 cm thick – with a large stylish handle.

The Finnish sauna for your home

Home sauna: Finnish sauna


When open, it looks like a normal Finnish sauna.

The interior is specious and designed to maximise space.

Now, you can have a Finnish sauna in your home even if you have limited space.


When it is not in use, it takes up less space than a wardrobe!

The sauna can be closed, so you can optimise the space in your home.

Wellness in your home, even if you have limited space.


Family Sauna and its fine interior

The cabin walls are made with fine ennobled spruce wood, with very few visible knots.

The benches are made of Ayous wood, imported from from Cameroon, which is a special wood with low heat conductivity, therefore does not feel hot to the touch, even in the high temperatures of a sauna.

Finnish sauna heater

In line with the best Finnish sauna tradition, the heater contains 10 Kg of peridotite rocks. Remember to add just a little bit of water at the time, when the rocks are very hot, to increase humidity and perspiration!

Family Sauna and LED lighting

The indirect lighting, 3000 K warm white, is courtesy of a special LED system that can withstand high temperatures.

Two Family Sauna versions

Family S Sauna

You can have your home sauna in just one square metre!

The sauna can be opened and closed with a simple gesture. When it is not in use, it only takes up one square metre. When you want to use it, it takes 10 seconds and no effort to open and your sauna is immediately ready.

How much room does Family S Sauna need?

Family S Sauna takes up very little space.

Open: 150x100x210h cm (1.5 square metres)

Closed: 150x60x210h cm (1 square metre)

How many seats does Family S Sauna have?
