Leil Patio S PLUS - 4-Person Outdoor Prefab Sauna

The Leil Patio S PLUS is a 4-Person outdoor prefab sauna kit engineered in Estonia. Delivered flat-packed for on-site assembly, with a base MAP of $15,330 - configure your heater, lighting, and (Patio S Plus/L Plus only) terrace-board extension to complete the build.

The Patio S Plus Outdoor Sauna Cabin Kit is designed for installation in the backyard and outdoor spaces across Canada and the USA. These saunas are classified as "prefabricated," meaning they are manufactured in sections or parts and shipped to the installation site in a well-packaged crate. The term "prefabricated" refers to the pre-made factory components, which can be quickly assembled according to the instruction manual, thereby simplifying the installation process compared to traditional saunas.

Crafted from Thermally modified Spruce, the Patio S Plus Outdoor Sauna Cabin Kits are durable and weather-resistant. They come with a choice of either a wood-burning or electric stove, a ventilation system, and comfortable benches made from Alder wood. The Patio S Plus model has a unique "L" shaped bench for extra versatility and comfort during use. Additionally, this unit features a stunning panoramic window view with two glass fronts, offering an unobstructed view of the surrounding environment. The open area is ideal for having an outdoor hot tub, cold tub, or sitting area.

All Patio models have a slight slope on the roof, which ensures proper drainage and prevents snow buildup, thereby reducing the need for maintenance and repairs while also maintaining the structural integrity of the unit over time.

About Leil Saunas - Estonian Engineering

Leil Saunas is an Estonian manufacturer designing prefab saunas at the intersection of Nordic material tradition and modern architecture. Every model is built on a single controlled manufacturing campus in Tartu county, Estonia, where thermally-modified timber, refined glazing, and integrated hardware are assembled into modular kits ready for the toughest US climates.

The word Leil refers to the steam generated when water is poured onto hot sauna stones - in Estonian culture, it signifies "breath" or "spirit." That philosophy shapes every choice: high-humidity sessions, balanced Soft Heat (a controlled temperature-to-humidity ratio that lets you stay in longer without the sting of dry heat), and materials engineered to feel as good in year 10 as day one.

What Makes a Leil Sauna Different

• 1.57" thick ThermoWood® - heat-treated timber with all resins and moisture driven out. Superior insulation, natural resistance to rot and insects, and long-term dimensional stability against warping.
• Cool-to-touch Aspen & Alder benches - low-thermal-conductivity woods that stay comfortable to sit on at 190-200°F.
• Panoramic tempered glass - clear or bronze-tinted 8mm glass fronts flood the interior with natural light while maintaining thermal efficiency.
• Precision triple ventilation - strategically placed intake, exhaust, and drying vents keep oxygen levels high and heat evenly distributed floor to ceiling.
• Weather-ready fortification - EPDM-sealed roofs or high-grade shingles, integrated drainage, and black-treated moldings for year-round outdoor durability.
• Modular assembly - pre-fabricated panels align cleanly; a two-person team can complete assembly in a weekend on smaller models.
