Thermally Broken Single Out-Swing Door
Style: TB 5050

Escape from the world in your bathroom or sauna richly enclosed with Portella steel doors. Spacious and airy with narrow stainless steel, they keep the space open and illuminated with large-expanse, true divided lites of glass rather than simulated divided lites commonly used by others. Portella’s true divided lites feature two pieces of glass, as opposed to one, which are separated by a muntin that is the same depth as the window/door unit, ensuring that fabulous authentic look you’re looking for. And, since each door is made of stainless steel, you needn’t worry about rust. Available in painted pewter, gun metal, chestnut, dark bronze, black or custom finishes. *Note: We do not warranty shower / sauna doors
