An inline steam enclosure runs full-height glass across a straight opening, all the way to the ceiling, with a fixed transom panel above a hinged door so the steam stays sealed in. It turns a standard alcove into a true steam shower.
Yours is built frameless in tempered safety glass, fabricated in our own Ottawa shop and professionally installed.
Select a configuration, enter the measurements that apply to that layout, then choose glass and hardware options. This keeps the original Centennial workflow while making it easier to expand.
An inline steam enclosure runs full height to the ceiling along one wall, with a sealed door and a fixed transom panel above, so steam stays inside. It turns a straight-wall shower into a steam room.
A steam enclosure is sealed to the ceiling — including a transom panel above the door — so the steam can’t escape. Regular enclosures stop short of the ceiling and are open at the top.
The transom is the fixed glass panel that closes the gap between the door and the ceiling, trapping heat and steam. It’s essential for the steam system to work efficiently.
Every enclosure is made from thick frameless tempered safety glass, paired with your choice of hardware finish — chrome, brushed nickel, matte black and more — and matching hinges. For help deciding, see our frameless vs. framed guide.
