Hetki

Hetki (meaning "Moment" in Finnish) is the essence of the real sauna: it is constructed from Finnish spruce logs, a tradition dating back to the oldest Finnish saunas. While many outdoor saunas are sold as kits, a Hetki sauna is handcrafted in Finland as a complete, solid-log building. It features a heavy-duty 88mm log frame and is delivered to your garden fully finished. There is no on-site construction; it is an authentic Finnish "Moment" ready to be enjoyed immediately.

Hetki saunas are delivered fully pre-assembled; they arrive at your UK address on a truck and are positioned using a crane lift. This ensures the structural integrity of Finnish log buildings is preserved. You simply need to provide a flat, load-bearing site, and once lifted into place, the unit is ready for its final connections.

Each Hetki sauna is made to order in the South Savo region of Finland, ensuring the highest standards of Finnish craftsmanship. The typical lead time is 10 to 12 weeks. This timeframe allows for the handcrafted manufacturing of your specific model and its secure transit to the UK.

Since a Hetki sauna is a substantial log building (often weighing between 1,500kg and 2,300kg), it requires a solid, flat, and load-bearing foundation. This can be a concrete pad, heavy-duty paving, or a reinforced timber deck. Because the sauna is supported by its own fixed bases, you do not need a separate sub-frame, but the ground must be perfectly level to ensure optimal door and ventilation performance.

Our Hetki units are designed for high-performance Finnish heaters. To power both the heat and the integrated lighting, you will need a dedicated power supply (armoured cable) installed on-site. As your UK reseller, we recommend having a qualified UK electrician ready to make the final connection once the crane has positioned your sauna.

The core of a Hetki sauna is its laminated Finnish spruce logs. Grown in the harsh northern climate, this timber is exceptionally dense and strong. The 88mm thickness provides natural, massive insulation and a vapour barrier system without synthetic materials. This "breathable" log construction is what creates the famous, soft Finnish steam (Löyly) and an oxygen-rich environment that cheaper saunas cannot replicate.

Yes, though for safety during transit, the chimney flue is temporarily disassembled. While the sauna arrives fully built, a qualified professional must reassemble the flue and pipe components on-site to ensure compliance with fire safety standards. As a UK reseller, we can guide you on the local requirements for this quick final step.
