Expert help that stays with you

Small details become expensive problems once installation begins. We ask the questions early, so a mismatched part, an overlooked requirement or an installation issue gets caught while it is still easy to fix.

Our job does not end when your order ships. We stay available through installation and beyond. If something needs attention, we stay involved, work the problem, and help see it through.

We want you to feel good about choosing Sauna Marketplace long after your first session, and confident recommending us to a friend. That standard guides the advice we give, the products we sell, and the way we take care of our customers.

Sauna and heater customers also receive free shipping on sauna accessories for life.

Planning a sauna, or need help with one you purchased from us? Our founders have built saunas from the crate up and both run saunas at home. New customers and existing Sauna Marketplace sauna and heater owners can Book a Ben consultation.

    Questions

    Do you offer installation?

    We don’t install saunas ourselves, but we have installers and electricians we’ve worked with before, and we can recommend them in most areas. Send us your ZIP code and we’ll check who’s near you. You hire them directly.

    If nobody we know is close, a handyman, deck builder or general contractor can assemble the kit, and a licensed electrician wires the heater.

    SaunaLife GL4 Outdoor Sauna Kit

    The SaunaLife GL4 is a four-person outdoor sauna kit that combines Scandinavian craftsmanship with modern design. Its 1.57″-thick thermally treated spruce walls provide superior insulation and durability, while the contrasting black exterior trim and integrated porch give it a refined architectural look. Expansive bronze-tinted glass on the front wall brings in natural light and allows you to admire your surroundings while relaxing inside.

    The interior features two tiers of satin-smooth thermo-hardwood benches that contour to your body for ultimate comfort. Knot-free and extra thick, these benches are designed for years of daily use. LED lighting under the eaves gently illuminates the porch, and indirect LED lighting inside the sauna creates a relaxing atmosphere. Both lighting zones are controlled by a Wi-Fi app or hand-held remote.

    Engineered for easy DIY installation, the GL4 arrives as a complete kit with interlocking wall panels, benches, roof, porch, floorboards, metal flashing, fasteners and a self-adhesive roof membrane. Two people with moderate experience can assemble it in about two days. The thick thermo-spruce walls and tempered glass ensure efficient heat retention and the included ventilation and drainage systems help keep the interior dry and comfortable.
