Bring the paradise of authentic sauna to your backyard with the Leil Black Cube Comfort Outdoor Sauna Kit. This DIY construction package comes with all the hardware, varnish, paint, sealant, and materials needed to build your sauna.
The Comfort's ThermoWood pine walls provide exceptional heat management and a stylish dark hue to the sauna interior. These properties also act as the perfect exterior protection, offering durable weather resistance in mild-to-harsh climates. Designed as a bold centerpiece for your backyard, the Comfort’s exterior architecture features an arched frame with a full tempered-glass front to deliver a striking aesthetic. You can even opt for a fully-tempered rear window for better views and a custom look.
A set of 2-tier alder and aspen benches hang on the walls in a double-I configuration, supporting up to 6 people or giving you the space to stretch out and lay down. These benches are equipped with bench skirts and backrests to bring incredible comfort for true relaxation.
The built-in ventilation system is perfectly placed to promote proper airflow, using several vents at optimal heights to keep a steady oxygen flow for easy breathing. This system works in tandem with the integrated floor drain to give excess water and vapor a quick escape route.
Designed to handle both electric sauna heaters and wood-burning stoves, the Leil Black Cube Comfort DIY Sauna Kit encourages you to customize your sauna experience for sessions tailored to your vision of perfection.
