Numa Large 3-5 Person Outdoor Traditional Sauna

Create a private outdoor wellness retreat with the Numa Large 3-5 Person Outdoor Traditional Sauna. Designed with a clean cabin-style structure, natural cedar wood, and a sloped steel roof, the Numa Large blends rustic outdoor beauty with powerful traditional sauna performance.

Built for both dry heat and Finnish-style steam sessions, this outdoor sauna is powered by a high-performance 9kW electric sauna heater with included stones. The heater is designed to warm up quickly, reaching your ideal temperature 50% faster than standard 6kW heaters, so you can enjoy a relaxing sauna session without the long wait.

The Numa Large is crafted with durable cedar wood and precision tongue-and-groove construction to help lock in heat and reduce cold spots. The extra-thick 8mm tempered glass door helps maintain consistent warmth while giving the sauna a clean, premium look.

With two stacked cedar benches, Wi-Fi smart control, dimmable LED lighting, included sauna accessories, and a spacious 3-5 person layout, the Numa Large brings the comfort of a traditional spa experience directly to your backyard.

Details & Craftsmanship

The Numa Large is designed for homeowners who want a traditional outdoor sauna with a refined cabin-style appearance. Its clean lines, natural wood finish, and sloped powder-coated galvanized steel roof make it a strong fit for backyards, patios, pool areas, and outdoor wellness spaces.

The sauna is built from durable cedar wood, creating a warm, aromatic interior that enhances every session. The precision tongue-and-groove construction helps improve insulation and heat retention, allowing the sauna to maintain consistent warmth from start to finish.

Inside, the two stacked cedar benches provide different heat experiences. The upper bench offers a hotter, more intense sauna session, while the lower bench provides a milder option for longer and more relaxed use.

The exterior is built for outdoor performance with a 29-gauge powder-coated galvanized steel roof that helps protect against rain, snow, sun exposure, rust, and corrosion. HDPE feet elevate the sauna to help shield it from ground moisture.
