What to Expect When Installing Frameless Shower Glass

The process cannot start until your tile is grouted and the corners caulked, because the glass is measured to the finished surface — not the rough opening. A glazier comes out, checks each wall for plumb with a level, records the door swing and the hardware locations, and notes any wall that leans so the panel can be scribed to match. This template is the single most important hour of the whole job; everything fabricated afterward is only as accurate as these measurements.

Your measurements go to the shop, where tempered glass is cut, the exposed edges are polished smooth, holes for hinges and handles are bored, and any anti-spot coating is baked on. None of this can be rushed — tempered glass cannot be trimmed after it is heat-treated, so it has to be right the first time. Expect roughly one to three weeks between the template and the install, and treat that window as fixed rather than negotiable.

The crew anchors hinges and clamps into the blocking behind the tile, then lifts the fixed panel and door into place and shims them dead-plumb until the reveals are even all around. The door is adjusted to hold at any angle, the wet edges and bottom sweep are sealed, and the swing is tested for clean closure. A typical enclosure goes in within a few hours, and you finish with a walk-through on how to operate and clean it.
