Answer a few questions and we will narrow it down for you.
NW Immersion Sauna Elite Panel
Most red light panels can't survive a real sauna — they overheat, dim, or fail. The Sauna Elite is engineered to run at temperatures 29°F hotter than any competing panel, so you get red and near-infrared therapy exactly when your body is primed to absorb it: during a full-heat sauna session.
The SaunaLife CL4G brings the warmth of authentic Finnish sauna bathing into a beautifully refined outdoor setting. Its distinctive rounded Cube architecture, panoramic bronze-glass front, and naturally rich Thermo-Spruce construction create a sophisticated wellness retreat that feels equally at home in contemporary backyards, garden spaces, and mountain cabins.

Whether enjoying the first light of morning or unwinding as evening settles over your surroundings, the panoramic design makes nature a beautiful part of every session.
Comfort is central to the CL4G's thoughtful interior design.
Premium Thermo-Aspen seating provides a silky-smooth, knot-free surface that remains comfortable against the skin in high-temperature sauna environments.

With room for up to three bathers, the CL4G is equally inviting for peaceful solo sessions, couples seeking extra space, or intimate shared sauna experiences.
The CL4G is constructed from premium Thermo-Spruce, a thermally modified Nordic wood selected for its natural beauty, dimensional stability, and suitability for outdoor sauna applications.
Its substantial 42mm side walls and 28mm front and rear wall components provide durable construction designed for lasting enjoyment.
The chemical-free thermal modification process enhances the wood's resistance to moisture-related movement, while its warm tones and distinctive natural grain preserve the timeless character of Scandinavian craftsmanship.
Inside, beautiful Thermo-Aspen benches and backrests create an inviting contrast with the surrounding Thermo-Spruce.
Beautiful design is matched by thoughtful engineering throughout the CL4G.
A complete shingle roofing system with protective drip rails helps manage rainfall and outdoor exposure, while durable structural components and foundation beams provide a stable base for the sauna enclosure.
Integrated ventilation components support proper airflow, contributing to a comfortable and authentic traditional sauna experience.
With appropriate site preparation, exterior maintenance, and proper installation, the CL4G is designed to bring the benefits of sauna bathing into your everyday routine throughout the seasons.
The CL4G includes an elegant white LED lighting system designed to create a smooth, inviting glow throughout the wood interior.
Its dimmable lighting allows you to personalize the ambiance, whether you prefer brighter illumination for a refreshing morning session or soft lighting for a peaceful evening retreat.
With WiFi-enabled smartphone operation and an included wireless handheld remote, creating your ideal atmosphere is simple and convenient.
Complete your CL4G with one of NW Immersion's carefully selected electric sauna heater packages.
Choose from compatible Harvia and HUUM heating systems with options for traditional controls or convenient WiFi-enabled operation.

After doing lots of research, we landed on the CL3G Cube sauna with the Huum Drop heater. The staff was professional and answers your message very quickly! They even made an accommodation to stop by their showroom so we can see them before we purchased. Support after delivery was also exceptional! Would highly recommend!
Hi there! We're thrilled to hear you had a positive experience with our service and that your shipment was quick. Thanks for sharing your feedback, we really appreciate it!
We’re super happy with our new sauna from NW Immersion! The whole process was smooth and professional, and the sauna itself exceeded our expectations. It looks beautiful, works perfectly, and has become one of our favorite places to relax. Highly recommend NW Immersion for their quality products and excellent customer service!
We absolutely adore our outdoor sauna. It's been a fun addition to our lifestyle and a nice experience to share with friends. The kit went together quick. The only part we had to purchase separately was a graphite rope to help with the exhaust seal on the stove, which helped significantly.
Thank you so much for your thoughtful review! We’re so happy to hear your outdoor sauna has become such a fun part of your lifestyle and something you can enjoy with friends. We also appreciate you sharing the helpful tip about the graphite rope for the stove seal. Wishing you many more relaxing sauna sessions ahead!
I love this sauna, but what specially made me want to write a review is the customer service. I was having trouble communicating with a few other sauna companies, and with NW I got on the phone with one of the business owners. She answered all the questions I had about the electrical and setup for this sauna, so grateful and highly recommend!
Between the manual and some online videos, a buddy and I were able to get this sauna together within a few days. I recommend you have a large area to lay the parts out and best if the weather is clear. Very pleased with the results and have had friends over to enjoy it as well which is awesome!
They answered all of my questions and assisted me with sourcing a local assembler. This is a great quality sauna that I use daily and have zero complaints.
