The right sauna door needs to handle extreme temperature swings, seal in heat, and fit your sauna's aesthetic. We carry full glass sauna doors and insulated cedar wood doors (with and without glass inserts) sized for both custom-built sauna rooms and pre-fabricated sauna kits. All doors include frames, hinges, and handles — everything you need for installation. Free shipping on every order.

Full tempered glass sauna doors are the modern standard for custom sauna builds. They let natural light into the sauna (or let you show off the interior from outside), make the space feel more open, and give a clean contemporary look. Tempered glass is a safety requirement — it's rated for the temperature differentials in a sauna environment and breaks into small, blunt pieces rather than sharp shards if damaged.
Glass doors are the most popular choice for indoor saunas, commercial installations, and modern outdoor builds where aesthetics matter. They do lose more heat than insulated wood doors (glass is a poor insulator), which means your heater works slightly harder to maintain temperature. In a well-insulated sauna with a properly sized heater, this difference is negligible for most users. If you're building in an extremely cold climate or are maximizing energy efficiency, an insulated wood door holds heat better.
Our glass sauna doors are available in standard sauna sizes and come as complete kits with the glass panel, wood or aluminum frame, hinges, handles, and magnetic or mechanical latches. Check individual product listings for exact dimensions and frame material options.
Insulated cedar wood sauna doors are the traditional choice and the best option for heat retention. Cedar is naturally moisture-resistant, rot-resistant, and aromatic — the classic sauna wood. Our cedar doors are insulated for maximum thermal performance, making them ideal for outdoor saunas, cold-climate builds, and off-grid installations where conserving heat matters most.
Wood doors are available with or without glass window inserts. A glass insert gives you the benefit of natural light and visibility without the heat loss of a full glass door — a good middle ground. Doors come complete with frames, hinges, and handles. Standard sizing fits most custom sauna room openings.
Choose glass if: you want a modern look, natural light inside the sauna, visual openness (especially important in small saunas to avoid a claustrophobic feel), or you're building a commercial sauna where visibility is a safety requirement. Glass is also easier to clean — just wipe it down.
Choose wood if: you're building in a cold climate and want maximum insulation, you prefer the traditional Finnish sauna aesthetic, or you're doing an outdoor/off-grid build where heat retention is a priority. Cedar doors also provide a warm wood scent that adds to the experience.
Choose wood with glass insert if: you want the insulation benefits of a wood door but still want some natural light and the ability to see in and out. This is the most versatile option and works well in virtually any build.
For a much deeper dive on materials, sizing, swing direction, clearances, and code considerations, see our comprehensive sauna door guide.
Sauna doors are typically shorter and narrower than standard household doors. The most common sauna door size is approximately 24" × 72" (2' × 6'), though sizes vary by model. The shorter height helps trap heat near the ceiling where it's needed — a taller door opening lets more hot air escape every time the door opens. When framing your door opening, always check the specific product's rough opening dimensions before cutting.
Key installation considerations include swing direction (most sauna doors open outward for safety — if someone collapses inside, an outward-swinging door can't be blocked), threshold and floor clearance for drainage, and magnetic vs. mechanical latches (magnetic is preferred because it can always be pushed open from inside). Our door guide covers all of these details with installation tips.
Looking for additional glass beyond the door? We carry tempered glass sauna windows and glass wall panels for builds that want even more light and openness. Glass walls are popular in modern and commercial saunas for a dramatic, spa-like look. All sauna glass is tempered and rated for sauna temperature conditions.
No. Standard household doors are not built for sauna conditions. They'll warp from the heat and moisture, the finish will degrade, and they lack the thermal performance a sauna requires. Sauna doors are made from heat-stable materials (tempered glass, cedar) with hardware rated for high temperatures and humidity.
Out. This is a safety standard — if someone becomes dizzy or faints inside the sauna, an outward-swinging door won't be blocked by their body. Many building codes require outward-swinging sauna doors. All of our sauna doors are designed to swing outward.
Glass is a poorer insulator than wood, so yes, a full glass door allows more heat transfer than an insulated cedar door. In practice, the difference is modest in a well-insulated sauna with a properly sized heater. Most users won't notice a meaningful temperature difference. If you're building in extremely cold conditions or running a smaller heater at the low end of its range, a wood door (or wood with glass insert) is the more efficient choice.
The standard sauna door is approximately 24" wide × 72" tall, though sizes vary. Measure your rough opening and check the product's specified rough opening dimensions before ordering. If you're framing a new opening for a custom build, follow the manufacturer's recommended rough opening size for the door you've selected.
Yes. All of our sauna doors ship as complete kits including the door panel, frame, hinges, handles, and latch hardware. You'll need basic tools for installation but no additional door hardware. Check individual product listings for the exact kit contents.
