Narvi Kuru 14 Through-the-Wall Wood-Burning Sauna Heater

Kuru 14 Through-the-Wall Wood-Burning Sauna Heater

*Flue kit and stones to be purchased separately*

The Narvi Kuru 14 Through-the-Wall wood-burning sauna heater embodies timeless Finnish craftsmanship, delivering the pure, invigorating heat essential for a truly authentic sauna experience. Designed for discerning sauna enthusiasts, it combines efficiency, durability, and understated elegance. 

Featuring a through-the-wall installation, the firebox is conveniently loaded from outside the sauna. This design keeps your sauna floor pristine and clutter-free while enabling convenient operation from an adjoining room. 

A glazed cast-iron door allows you to enjoy the mesmerising glow of a live fire, creating a warm, inviting atmosphere beyond the sauna itself. The black-painted steel housing exudes minimalist sophistication, while ergonomically crafted wooden handles ensure comfortable, safe handling during use. 

*Please note that some of the images are for illustration purposes only. The flue kit should be purchased separately. We recommend the Kota Insulated Steel Flue/ Chimney Kit.

Note: Sauna stones to be purchased separately

This heater requires up to 35kg of sauna stones. We recommend using 10-15cm Olivine Diabase or Vulcanite Sauna Stones for optimal performance.

All Narvi sauna products are CE tested and bear the Finnish Key Flag Symbol. This is awarded to sauna equipment that is made and designed in Finland, where over 95% or more of the production must be within Finland itself. There are many brands that claim to be made in Finland but are actually made in the Far East or Russia and merely assembled or labelled in Finland. Watch out for these symbols as a mark of an authentic, Finnish-made, safe, quality product:

As part of Finnmark Sauna's Endurance Ethos, we only deal in products that are market leaders in quality. We commit ourselves to search exhaustively for the highest quality authentic Finnish sauna products.

Please note, we recommend that sauna heaters should be installed by a suitably qualified builder/plumber. Finnmark Limited accepts no liability for loss or injury caused by the incorrect installation of your sauna heater. Please Contact Us if you require information on our recommended fitters.
