The Changing Room

My changing room is 92″ × 66″ — the same footprint as the sauna itself, adjacent to it. It serves as the transition space between the house and the sauna: a place to undress, store towels, and cool down after a session.

Layout and purpose

The changing room sits directly adjacent to the sauna, sharing one wall. The door between them opens into the sauna — which means it opens outward from the sauna's perspective, meeting the safety requirement. The changing room door to the house opens inward or outward depending on your layout.

The main functions are: undressing and dressing before and after sessions, storing towels and robes, and providing a cooler space to decompress after the heat. A bench or seating area for putting on shoes is useful. Storage for towels and personal items keeps the sauna itself uncluttered.

Key design decisions

• Flooring: Should handle wet feet — tile, sealed concrete, or a waterproof vinyl plank. Avoid carpet. A small drain is helpful if you install an outdoor shower or plan to rinse off before entering.
• Ventilation: The changing room doesn't need the same intensive insulation and vapor barrier system as the sauna, but it should be well-ventilated to handle humidity from the sauna door opening and closing.
• Lighting: Warmer, lower light than the rest of the house — the changing room is part of the sauna experience, not just a hallway.
• Hooks and storage: At minimum, hooks for robes and towels at two heights (adults and children). A small bench at seat height for dressing.
• Mirror: Optional but practical, especially if the changing room doubles as a changing area for guests.

Finishes

The changing room doesn't need cedar cladding the way the sauna does — you're not dealing with extreme temperatures. But it makes sense to carry some visual continuity between the two spaces. Cedar accents, matching hardware, and a consistent palette tie the two rooms together and make the changing room feel intentional rather than incidental.

Connection to the sauna

The door between the changing room and the sauna is a significant thermal boundary. The sauna door should be well-gasketed to prevent heat loss into the changing room. Some builders add a small vestibule or airlock between the two spaces — not essential, but it reduces heat loss and gives a more deliberate transition.
