Portti™ Clear Glass Sauna Door 27" x 74"

The door panel measures 24 inches by 73 inches. Its full framed size is 27 5/32 inches by 74 13/32 inches, and it needs a rough opening of 28 1/8 inches by 76 inches. Measure your opening against these exact figures before ordering, since the door arrives pre-hung and is not cut to fit on site.

Measure the framed opening in your sauna wall, meaning the gap left for the door unit, not a finished door. Check width at the top, middle, and bottom, and height on both sides, then use the smallest reading. Your opening should match the 28 1/8 inch by 76 inch rough opening this door requires.

Pre-hung means the glass panel arrives already mounted in its alder jamb with the hinges and handle fitted, so you install the complete unit rather than assembling parts. You still need a correctly sized, square rough opening framed into your sauna wall. The door drops into that opening, then gets shimmed level and secured.

Many builders install a pre-hung sauna door themselves if they are comfortable setting a door into a framed opening, shimming it level, and fastening the jamb. The work is standard door hanging, not specialized glass work. If your opening needs adjusting or you are unsure it is square, a carpenter can handle it quickly.

Sauna doors open outward, the safety standard for the category, and this door follows that convention. The door is fixed right hand opening, the swing is not reversible on this model. Confirm your hinge side against your room layout before purchasing.

The panel is tempered glass, which is far stronger than ordinary annealed glass and, if it ever does break, fragments into small blunt pieces rather than long sharp shards. That fragmentation behavior is the core safety property of tempered glass and the reason it is the standard for sauna doors.

Tempered glass is made to tolerate the heat and the heat-to-cool swings of regular sauna use, and it resists thermal stress far better than ordinary glass. Avoid pouring cold water directly onto hot glass or striking the edges, since sharp impacts and extreme local shocks are what put any glass at risk.

The glass warms during a session, but the panel sits at the door, away from the heater, so it stays cooler than the stones or the air near the ceiling. Open the door using the handle rather than pressing your palm flat against warm glass, and it is comfortable to use throughout a session.

Light condensation can form on the glass during a humid session, the same way a bathroom mirror fogs, and it clears as the sauna airs out afterward. It is surface moisture, not damage. Leaving the door open to dry after each use keeps the glass clear and prevents water spotting over time.

The glass is 8mm (about 5/16 inch) thick, tempered glass.

Clear glass is fully transparent and makes a compact sauna feel open and bright. Grey is a tinted, semi-private glass that softens the view into the room while still letting light through. Both use the same tempered glass, so the choice comes down to privacy and look.

No, its made from wood. Wood stays far more comfortable to the touch in a hot sauna than bare metal would, which is exactly why the grip is wood rather than metal. You hold the grip, not the bracket.

The jamb is alder, a dense hardwood that naturally resists moisture and handles sauna heat and humidity without warping or degrading, which is why it is used instead of a softer wood. Alder is typically left untreated inside a sauna.

The door fits its jamb closely and holds sauna heat in during a session. Sauna doors are not built to be airtight, because a sauna needs some air exchange to run well and to dry out afterward. A close, consistent fit is the goal here, not a sealed-shut chamber.

Sauna doors open outward, and this door is no exception. Outswing is the safety standard for saunas, because an outward-opening door cannot be blocked by anyone inside and is never jammed shut by heat expansion. It is the convention every properly built sauna door follows, not a brand-specific feature.

The door does not lock, by design. A sauna door must never lock so no one can be shut in. It latches with roll lock to stay closed during a session but can always be opened. There are no keys and no exterior locking mechanism on a sauna door.

Treat it like any sauna door. A child should never be in a sauna without an adult present, and this door is built so it can always be opened and never locks. The panel is tempered glass, the category safety standard. Adult supervision is the real safeguard, on any door.

his door is built for indoor saunas, both traditional and infrared. It isn't rated for outdoor use or the constant wet of a steam room, where the frame and hardware would be exposed to conditions they aren't made for.

Wipe the glass with a soft cloth and a mild glass cleaner or diluted white vinegar, avoiding abrasive pads that can scratch. Give the frame a quick pass with a damp microfiber cloth to keep it looking clean. Drying the door after use reduces spotting.

A glass door lets light flow into the sauna, makes a small room feel open, and lets you see in and out, which a solid wood door cannot. Tempered glass also will not warp, swell, or absorb odors the way wood can over time. The alder jamb keeps the warm wood look at the frame.

A standard shower door is not a substitute. Shower doors are built for warm, wet conditions, not the sustained high heat of a sauna, and they may use glass, seals, frames, or hardware that are not rated for it. A purpose-built sauna door uses tempered glass, an outswing safety design, and heat-rated materials throughout.

The door is built from materials chosen to last through regular sauna use: tempered glass and a moisture-resistant alder jamb. Includes a one year warranty.

A pre-hung glass door is heavy and ships by freight, so inspect it on arrival before signing for it. Note any visible damage to the packaging or the glass with the carrier at the point of delivery.

The door uses hinges from Abloy, the Finnish hardware manufacturer founded in 1907 and known for precision door and lock hardware. The hinges come already fitted into the alder jamb as part of the pre-hung unit, so they arrive set and aligned with no separate hardware to assemble.
