The following are general guidelines to help you prepare for a safe and cost-effective heavy glass shower installation.
Every door hinge has a manufacturer required weight and width restriction. For example, a pair of "Geneva" style hinges have a maximum door width of 28" and a maximum door weight of 80lbs. "Vienna" style hinges have a maximum door width of 36" and a maximum door weight of 110lbs.
Manufacturers require hinges to be fastened through the tile and into wood blocking. We recommend that solid wood blocking be installed vertically at least to the top of the enclosure and to the full width of the sill. The wall where the hinges are to be mounted must be straight so the pivot point of all hinges are aligned. The wall does not have to be plumb but it must be straight.
A door can be hinged off of a fixed sidelite panel that is not supported at the top when the fixed panel is 1/2" thick and is 22" wide or less. The sidelite must also have hinge-sized L-shaped wall clamps at the same height as the hinges otherwise the panel must either be secured to the ceiling or secured with a header bar.
For safety reasons, all sidelites must be mechanically fastened in the opening using channels or clamps.
The sill or curb must be pitched into the shower for water to drain properly. If the sill is near level or slopes only slightly, the shower enclosure will leak unless a threshold is used to try and create a dam. Remember to remove shipping bars from solid sills and fill the void with thin set to avoid cracking the sill when it is drilled. Corner enclosures should use standard angles of 90 degrees or 135 degrees if possible. Other angles are possible but will typically be more expensive.
The face of the buttress wall should always be at 90 degrees to the sill. Angles other than 90 degrees are always more difficult to enclose. In a door opening, the buttress wall must be plumb so the door will align to the glass panel sitting on top of the buttress, otherwise the panel must be notched and extended down to the sill to provide a plumb vertical joint to the door, as well as also reducing the opening width available for the door.
Seats inside shower enclosures should slope downwards towards the shower base for water runoff and panning should be used to prevent water leakage through the tile.
The footprint of the sill should exactly mirror the footprint of the soffit. Plumb down to ensure that they are the same. If are not, it will be extremely difficult to align the reveal of the glass to the sill and soffit and the final product will look awful.
Whenever showers are enclosed from sill to soffit, a steam enclosure is created whether you want one or not. Consider an operating pivoting transom above the door or at a sidelite to vent excess steam. In these instances we strongly recommend a fan be installed inside the shower enclosure. The ceiling must be tiled and should extend past the edge of the enclosure.
Never design an enclosure with glass panels narrower than 4" wide. The minimum width of tempered glass is 4". The maximum size of a glass panel depends on the accessibility to the shower enclosure, including narrow spaces and low ceilings.
If a door is being mounting on a wall with raised tiles, tiles must be notched or flat tiles installed for the entire door swing area wherever the decorative tile comes into contact with the glass. For fixed glass panels butting to raised tiles, you should notch the tile slightly wider than the thickness of the panel.
Reality is no shower enclosure is completely water proof. The smaller the shower space and closer the shower head is to moving parts such as swing doors or moving panels, the greater the chance that water will find its way over or around the moving parts. Water may also end up on the floor when the sill is not pitched sufficiently or where walls abutting a door bow away from or into the door. As a general rule, shower heads and body sprays should never be designed to face the door.
