Effortless Assembly
Step into the luxurious Lasi Sauna, where contemporary design meets traditional warmth. Built with a robust Thermowood structure and featuring our innovative panel construction, this sauna is designed for effortless setup. With just two people, the main structure can be assembled in just a few hours, making it one of the easiest saunas to build.
Panoramic Views and Versatility
The Lasi’s standout feature is its corner window, consisting of three panoramic glass panels and a fully tempered glass door, filling the space with natural light while offering stunning outdoor views. A retractable bench adds versatility, creating extra floor space for stretching, yoga, or simply enjoying a more open atmosphere.
Thoughtful Insulation Design
To ensure optimal heat retention, the wall panels of the Lasi Sauna are fully insulated. The roof and floor have been thoughtfully designed to accommodate insulation as well. However, due to the low cost and accessibility of insulation materials from local hardware stores—and the bulkiness and inefficiency of shipping them across the country—we have chosen not to include roof and floor insulation in the package. This approach allows you to source the insulation locally, saving on unnecessary shipping costs while maintaining excellent thermal performance.
Functional Design Details
Additional thoughtful design elements include a small overhang to keep towels and robes dry and easily accessible. For added flexibility, the door can be installed on either wall, ensuring it seamlessly fits into your outdoor space.
Durable Thermowood Structure
The Lasi’s Thermowood structure offers exceptional durability and weather resistance, making it ideal for outdoor use. Thermowood undergoes a specialized heat treatment process that enhances its natural resistance to moisture, rot, and insects without the use of chemicals. This ensures the sauna withstands harsh climates while maintaining its integrity and appearance, reducing maintenance requirements over time. Learn more about thermowood here.
Comfortable and Modern Interior
The interior is crafted for both comfort and functionality, complementing the Lasi's modern aesthetic. With its panel construction and versatile features, this sauna delivers an unparalleled relaxation experience in a design that’s built to last.
Important Notes
Please note: To comply with local electrical codes and accommodate unique climate conditions, lighting for this unit should be sourced locally. Additionally, the sauna will arrive in an untreated finish, allowing you to choose a treatment best suited to your environment.
