Overview

The Barrel — Large — Wood Back — Stone Heater is a 8-person sauna with an external footprint of Ø2100 × 3000mm long and roughly 5.8 m² of internal bench space. It is one of our barrel saunas — a classic round shape that heats quickly and suits compact gardens.

Construction uses our standard panel system: 12 mm interior cladding over 50 mm rockwool insulation, a sealed vapour barrier, then 12 mm exterior cladding on a kiln-dried frame. The interior is low-conduction thermo-treated timber so the benches stay comfortable at full heat, while the exterior can be specified in pine, teak or red cedar.

It is sized for a 9kW · 240V heater. Heaters from 3–9 kW run on a single-phase supply; only larger commercial heaters above 9 kW need three-phase, and the exact wiring is shown in the 3D builder as you design.

Every Barrel — Large — Wood Back — Stone Heater is made to order in Thailand with a 28-35 days lead time from confirmed deposit, and ships nationwide or worldwide as a flat-packed kit with assembly instructions. Open the 3D designer to change the timber, add a full glass front, adjust the benches and watch the price update live before you request a quote.

What payment and warranty terms apply?

With on-site assembly: 50% deposit to confirm the order. The final 50% is due on the day of delivery, after the sauna has been fully assembled and tested. If the required electricity supply is unavailable when our team arrives and testing cannot take place, the final 50% is due on arrival, before delivery proceeds. The client must arrange the supply in advance; unavailable power does not postpone final payment. The client must have a suitable, energised power supply ready no more than 3 metres from the agreed sauna power connection point before delivery, so the sauna can be tested after assembly. A qualified electrician must prepare the supply to the specified voltage, phase and capacity. For delivery or collection only, the balance is due before dispatch. Every sauna carries a tiered warranty: 10 years on the structure and build, 5 years on the sauna wood, and 1 year on the electronics (heater and controls).
