Not special glass. A steam enclosure uses the same heavy tempered safety glass as any frameless shower, 3/8 or 1/2 inch. What changes is everything around the glass: the enclosure runs to the ceiling, a transom closes the top, every joint gets detailed to hold vapor, and the hardware has to live in constant heat.
An ordinary shower stays open at the top on purpose, because moving air carries moisture out of it. Steam is the opposite problem. Vapor rises, and any opening above the door is where it escapes, taking the whole point of the room along with it. So a steam enclosure gains a fixed transom panel above the door, glass carried up to the ceiling line, and a ceiling panel where the ceiling sits too high to reach comfortably. The door becomes one sealed part of a small room instead of a screen standing in front of a spray.
Vapor finds paths a splash never would. Every vertical joint between panels, every wall channel and every glass-to-glass connection gets sealed, and the door carries seals around its full perimeter rather than a sweep at the bottom alone. Hinges and clamps sit inside a hot, humid box each time the generator runs, so hardware and the gaskets within it need specifying for that duty in whichever finish you choose.
None of that replaces waterproofing behind the tile. A steam room wants a proper vapor barrier and a sloped ceiling installed long before glass shows up, and that work belongs to the tile and build side of the project. When the substrate is right, an enclosure seals cleanly. When it is wrong, no quantity of silicone at the glass will rescue it.
The best steam enclosures include a way to open the top. An operable transom, hinged or sliding, lets a room that has been at full humidity dry out afterward instead of holding vapor against tile and hardware. It also cuts the mineral film that builds on glass in a room where every surface condenses, which is the practical reason steam owners so often ask about a protective coating in the same conversation. Leaving that transom cracked open between uses does more for the hardware and the tile than any cleaner ever will. Accurate Glass & Mirror builds custom steam enclosures out of the Lodi shop, measured to the finished room.
Sometimes, though the decision gets made behind the tile rather than at the glass. A steam room needs a continuous vapor barrier, a sloped ceiling, and a generator with somewhere to live. If a bathroom is being gutted anyway, adding steam is a reasonable conversation to open early. Sealing an enclosure onto a standard shower never waterproofed for vapor tends to end badly.
Yes, and from across the room it reads like any other frameless job. Heavy glass hangs on the same style of hinges and clamps, offered in brushed nickel, oil-rubbed bronze, matte black and polished chrome. The differences live in details: a transom above the door, seals running the full perimeter, and hardware chosen knowing it will sit in heat and humidity for years.
Plan the glass while the walls are still open and the whole assembly goes together properly. Our free residential measure happens at your house, fabrication happens in the Lodi shop, and installation is done by our own crew, so a steam enclosure stays one shop's responsibility from start to finish.
