The garden ritual

- Warm 8 kW Harvia Virta The heater warms the room and the stones together. Heater stones and WiFi control included.
- Step out Across the garden A compact footprint for three to four people on a prepared site.
- Pour Water on the stones A ladle of water adds a short burst of humid heat.

The honest math
$17 a session
$36,092, used 4 times a week for 10 years, works out to about $17 per session, before foundation, site work, installation, electrical work and power. Your own rhythm sets the real number.
Why we carry it
Spectra is a compact outdoor room for gardens that cannot give up much space but still want a sauna with a strong face. An outdoor room is a site project: plan the foundation, the electrical run and delivery timing with us before you order.
