    I just recently purchased the mini cube. The sauna is amazing and beautiful and can't wait to enjoy it long term with my family. But most I'm impressed with is the customer service from both sales and after sales. The team is very responsive. I asked too many questions and I appreciate the patience and quick actions to rectify the issue. Thanks again to the team at Redwood Outdoors!!

    I recently had the pleasure of transforming my backyard into a personal wellness retreat with Redwood Outdoors, and I couldn't be happier with the experience! From the outset, their customer service was nothing short of spectacular. The team was not only responsive but also incredibly knowledgeable, ensuring that all my questions were answered with great detail and care. The quality of the wood and materials used in my sauna and cold plunge pool is evident, boasting a high-grade, luxurious feel that seamlessly blends with the natural aesthetics of my outdoor space. The craftsmanship is impeccable, with attention to detail that promises durability and style. Installation was a breeze using their videos, thanks to the professional and efficient service provided by the Redwood Outdoors team. They handled everything with such proficiency that it transformed what I thought would be a complex setup into a smooth and easy process. Using the sauna followed by the invigorating cold plunge has become my daily ritual, and it's genuinely uplifted my quality of life. I highly recommend Redwood Outdoors to anyone looking to invest in their health and well-being with products that are as beautiful as they are functional. This company truly stands out with its exceptional service and superior quality products.

  • HARVIA KIP ELECTRIC HEATER

    HARVIA KIP ELECTRIC HEATER

    The KIP family of electric sauna heaters are traditional Finnish wall-mounted heaters. They heat up fast and reach high temperatures of ~190F within one hour. This design holds up to 40 lbs of rocks, on which you can douse water to create soothing steam. The KIP creates a relatively dry heat and you should expect ~15-25% relative humidity in the sauna. The KIP comes in an attractive stainless steel exterior case that easily mounts on your sauna wall.

    Harvia is the world’s leading sauna heater manufacturer and Harvia heaters are considered the industry gold standard. Harvia was established in Finland in 1950 and has built an international reputation for exceptional quality.

  • HUUM DROP ELECTRIC HEATER

    HUUM DROP ELECTRIC HEATER

    The HUUM DROP is an award-winning sauna heater. Made in Estonia, this eye-catching heater is quickly emerging as a stand-out in modern sauna design. Its shape is inspired by the purest element in nature – a water drop. Its round design softens and livens up the interior of a classic sauna, giving it a touch of elegance.

    But DROP isn’t only about the looks. This compact wall-mounted heater can fit up to 120 lbs of sauna rocks. This guarantees both hot temperatures and long-lasting steam. The HUUM is fast to heat up and can reach temperatures of ~195F. The HUUM creates more steam than the KIP heater, but less than the Cilindro heater. It's somewhere in the middle in terms of its “löyly” potential.

    Every HUUM DROP heater comes delivered with HUUM sauna stones and a HUUM UKU Wi-Fi controller. This makes it a must-have heater for customers who like a modern look, combined with modern functionality.
