High Quality Kits Made in USA

Every Soluna is produced in-house at Soluna's U.S. manufacturing facility, backed by more than 12 years of expertise in high-quality, design-forward outdoor structures that elevate everyday living. Built by skilled American craftsmen, each kit elevates durability, beauty, and wellness in a design that lasts.

Designed for Comfort and Connection

Unlike traditional barrel or cabin saunas, Soluna’s design maximizes comfort and sensory delight:

Spacious, Light-Filled Interior

Translucent panels bathe your sauna in soft, natural light — creating an open, uplifting atmosphere. At the same time, the design preserves privacy from outside view, offering seclusion without sacrificing connection to nature.

Comfortable for Every Body

Find your perfect heat zone — closer to the steam and higher heat up top, or gentler warmth below. A functional, tiered system designed for everyday adaptability and ease of use.

Ventilation

Fresh air intake and exhaust vents work seamlessly with the heater to promote natural airflow and breathability, eliminating CO2 and keeping the sauna comfortable.

Materials

Built with Premium, Non-Toxic, and Sustainable Materials

Every Soluna sauna is made with purpose and care, blending durability with natural beauty.

Premium materials avoid hidden toxins (laminated woods, off-gassing finishes, poor ventilation) with high-quality thermal panels for weatherability and high temperatures without compromising air quality or comfort.

High Quality Cedar

Each unit — from structure to benches and flooring — is built from Japanese cedar (Sugi), prized for its natural durability, moisture resistance, and calming aroma. With its warm hue, straight grain, and subtle, woody scent, Sugi creates a tranquil, lasting environment that feels both grounded and refined.

Commercial Grade Thermal Panels

Our translucent wall panels are built from premium, heat-safe materials engineered for demanding, high-temperature environments. Manufactured from non-toxic composites, they are trusted across outdoor and thermal building applications for their stability, safety, and durability. In the sauna, they hold their shape under heat, won’t off-gas harmful VOCs, and can provide passive solar heating.

Wood Stove Aluminum Shield & Steel Floor Plate*

High-quality, rust-resistant aluminum and steel surround the wood stove, deflecting heat and protecting the sauna, ensuring safety and durability.

*Accessories sold separately for wood stove installation.

Shipping

Flat-Packed & Ready to Go

Each Soluna Sauna is thoughtfully flat-packed and shipped directly to your site.

Details:

Lightweight & Efficient

Our modular design makes each kit easier and less expensive to move.

Lower Shipping Costs

Unlike traditional sauna kits that can cost up to $1,500 to ship (no matter if you live next door or across the country), Soluna ships for significantly less.

Nationwide Delivery*

Whether you’re in the city, at the cabin, or out on some land, Soluna can reach your location. Because Soluna ships on an oversized pallet, liftgate service may not always be available. In some cases, hand unloading may be required at delivery. Each Soluna component is designed to be lightweight and manageable, making it easy to move by hand and transport to your storage or installation site.

Reduced Footprint

A lighter, flat-packed system means fewer trucks, less fuel, and a smaller environmental impact.

Soluna proves that a sauna can be world-class in quality without the heavy burden of oversized shipping.

Easy Assembly for Your Backyard Sanctuary

Designed for flexibility and ease, Soluna’s modular kits come with clear instructions and everything you need to build a premium sauna that fits your space and style. Whether you’re a DIY enthusiast or a first-time builder, we make it simple to create a wellness retreat right at home.

Durability in Harsh Elements

Soluna has been tested with a Zone 4b Minnesota snow load. If you live in an area that experiences deep and heavy snow, we recommend installing plywood over the top of the Soluna during the most snowy months. We also reccomend snow-raking your roof in the winter to avoid snow and ice buildup, which can cause the roof to sag or fail under extreme weight.

Discuss with a builder in your area familiar with local codes and regulations to determine if extra materials are necessary to protect your Soluna during extreme weather events.
