Outdoor saunas are becoming a familiar sight at villas, especially in Bali and other holiday destinations. For villa owners, a sauna is an amenity that sets the property apart and makes guests want to stay longer. At a private home, it becomes a daily corner for relaxation.

To make sure your sauna is comfortable and lasts for years, a few things are best decided before you order. Here is the short guide we usually walk through with our clients.

1. Decide on capacity and who will use it

Start with a simple question: how many people usually use the sauna at the same time?

  • Couples or small villas (1–2 bedrooms): a compact two-person cabin is usually enough — for example the Sauna Cube Small, about 1.3 × 1.74 × 2.1 m outside.
  • Families or larger villas: choose a cabin for 4–6 people, such as the Sauna Cube Large (about 2 × 2 × 2.4 m) or the Sauna Barrel (Ø 2 m, 2.4 m long).

A cabin that is too large for everyday use takes longer to heat up, while one that is too small feels cramped. Choose for how the sauna will actually be used, not simply the biggest model.

2. Measure the site and check delivery access

Once you know the model, measure the available area. Leave space around the cabin for airflow, for maintaining the outer walls, and for comfortable access. With a wood-fired heater, the firebox and chimney also need a safe distance from walls, roofs, and trees.

Don't forget the delivery route. Saunas arrive as large, heavy pieces — the Sauna Barrel, for example, weighs around 450 kg. Make sure a truck or handling equipment can get close, and check the width of lanes, side gates, or steps along the way. Send us photos of the site so we can review it early.

3. Prepare a level, dry foundation

A good base is the key to a long life for a timber sauna:

  • The surface should be level and solid — a concrete slab, pavers, or a sturdy deck.
  • Avoid placing the sauna directly on soil or grass that often gets wet.
  • Make sure rainwater drains away from the cabin and never pools underneath.
  • Where possible, keep a small gap between the sauna floor and the ground so the underside stays dry.

4. Choose a heater: electric or wood

All our models can be fitted with an electric heater or a wood-fired heater. Each has its own advantages.

An electric heater is convenient: switch it on, set the temperature, and there is no smoke. Make sure the villa's electrical supply is sufficient and that installation is done by an experienced electrician.

A wood-fired heater such as IGNIS gives a classic sauna atmosphere with a visible flame. IGNIS heaters use an external firebox, so fuel is loaded from outside and smoke stays out of the cabin. They burn wood pellets or thoroughly dry firewood — a good option where electrical capacity is limited, as long as there is a safe place for the chimney.

5. Materials and finish for a tropical climate

Indonesia is humid, rainy, and sunny, so look closely at these details:

  • Timber: we use local Indonesian pinewood — light, fresh-scented, and comfortable to touch when hot.
  • Exterior finish: an outdoor coating (we use Lasur-Impra) helps protect the wood from water and sunlight.
  • Roof: asphalt shingles keep rain off the cabin.
  • Fixings: stainless steel straps or rings resist rust.
  • Glass: tempered glass doors and façades are safe at high temperatures.

The inside of a sauna should not be painted or varnished with ordinary products, which can become sticky and give off odours when hot.

6. Think about guest flow, privacy, and the view

A sauna is most enjoyable when it is easy to reach from the bedrooms or pool, close to a shower for rinsing off, and screened from the neighbours. If you have a view of rice fields, a garden, or the sea, face the glass door towards it — it makes every session feel special.

Don't forget a changing room and rinse bathroom nearby. Teak vanities and shelves from Java Bamboo Craft's teak bathroom collection keep the look in tune with the sauna's timber.

7. Provide usage guidelines for guests

For rental villas, place a short guide near the sauna: recommended session length, the importance of drinking water, no sauna use after drinking alcohol, and advice for guests who are pregnant or have a medical condition to consult a doctor first. Include how to switch off the heater as well.
