KOHLER^® C1 Indoor Sauna Roof Kit

The C1 Indoor Sauna Roof Kit is the matching ceiling assembly for KOHLER C1 indoor sauna cabins, sold separately for installations that require a roof component shipped or replaced independently of the cabin itself. The kit is sized to match the cabin size you own — Small, Medium, or Large.

The Bold Look of KOHLER^® Wellness

For more than 150 years, the KOHLER name has defined gracious living and bold design across kitchens and baths. The new KOHLER^® Wellness collection brings that same commitment to materials, craftsmanship, and engineered performance to a category that’s long overdue for a refresh: the home sauna. Every KOHLER sauna is handcrafted from premium woods, sealed with a fully integrated vapor barrier, insulated with thick mineral wool, and engineered to deliver consistent heat session after session — backed by Kohler’s 5-year warranty and supported by an authorized dealer network trained directly by Kohler.

Why KOHLER Saunas Are Different

Handcrafted Quality & Craftsmanship

KOHLER saunas are built to last. Premium hardwood selection, precision-milled tongue-and-groove paneling, and meticulous joinery work together to deliver a sauna that holds its shape, holds its heat, and holds up to daily use — backed by Kohler’s industry-leading 5-year warranty.

Engineered Performance You Can Feel

Designed from the inside out, every KOHLER sauna features robust wall construction, high-quality mineral-wool insulation, and an integrated vapor barrier that work together to retain heat efficiently and evenly. This thoughtful construction keeps the exterior surface comfortable to the touch even when the cabin is fully heated — supporting safer, more confident use around children and pets.

Aerotherm Ventilation & Dual-Thermostatic Control

Integrated Aerotherm venting draws fresh air through the cabin continuously, keeping the climate consistent from bench to ceiling. Dual-thermostatic control optimizes the cabin temperature against the heater output, while UL certification ensures safe, reliable operation session after session.

Versatile By Design

KOHLER sauna cabins are available in three sizes and curated exterior finishes so the cabin fits the room, not the other way around. Modern aesthetics and thoughtfully chosen materials let the sauna integrate seamlessly into a primary bath, basement wellness room, or backyard retreat.
