Sauna Door: Glass vs Wood
The sauna door might seem like a minor detail, but it affects heat retention, aesthetics, the overall feel of the room, and even your heater sizing. The two main options are tempered glass doors and solid wood doors, and each has legitimate advantages.

Glass Sauna Doors
Advantages:
- Natural light enters the sauna, creating a brighter, more open atmosphere
- Views to the outdoors (especially nice for backyard saunas with garden or forest views)
- Reduces feelings of claustrophobia in smaller saunas
- Easy to clean - glass doesn't absorb moisture or odors
- Modern, spa-like aesthetic
- Safety - you can see if someone needs help inside
Considerations:
- Glass loses heat faster than wood. Expect to upsize your heater slightly to compensate
- Can create a "cold spot" near the door on the lower benches
- Tempered glass is mandatory - regular glass cannot handle the thermal stress and will shatter
- Slightly higher upfront cost than a basic wood door
Wood Sauna Doors
Advantages:
- Better insulation - wood retains heat more effectively than glass
- More traditional look, especially in Finnish-style saunas
- Creates a more enclosed, cocoon-like atmosphere that some people prefer
- Lower cost
Considerations:
- No natural light or views
- Room can feel darker and smaller, especially in compact saunas
- Wood doors can warp over time if not properly built from thermowood or other dimensionally stable material
Combination Doors
Many sauna doors use a wood frame with a tempered glass panel. This gives you the light and views of glass with some of the insulation benefit of wood around the perimeter. It's the most popular option in modern home saunas for good reason - you get the best of both worlds.
Door Specifications
Sauna doors should open outward (for safety - you need to be able to exit easily if you feel overheated). Standard height is 72-76 inches, and width is typically 24-28 inches. A smaller door reduces heat loss. Glass should be at least 8mm tempered safety glass. Hardware should be stainless steel to resist corrosion.
The door should seal well but not lock. Latches are fine; locks are a safety hazard.
