    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.
