How shower door installation works, step by step

Stage 1 — Planning can start early (and should)

Nothing about fabrication can happen early, but almost every decision can. Style (frameless vs. semi-frameless vs. framed), glass type, hardware finish, door swing direction, whether a bench or transom is involved — all of it can be settled while the remodel is still studs and dust. Starting early also surfaces the two planning items that actually affect other trades: solid backing in the wall where heavy frameless hinges will mount, and a curb pitched correctly toward the drain. Mention both to your remodeler before the walls close up; they're cheap then and expensive later.

Stage 2 — Why the tile has to be done first

Tile and its setting bed add real thickness, tile setters work to their own lines, and finished walls are never exactly the framed dimensions. Because the glass in Stages 4–5 is cut to fractions of an inch and cannot be trimmed, measuring early builds error into a part that can't absorb it. This is the single most common schedule misunderstanding in bathroom remodels: homeowners expect the glass to arrive with the tile. It can't — it's the last thing ordered, by design.

Stage 3 — What the measurement visit actually covers

A good measurement visit takes longer than homeowners expect, because the installer is making every remaining decision with a tape and a level:

• Opening dimensions at multiple heights and widths — openings are rarely rectangles; the smallest and largest readings both matter.
• Plumb and level — how far each wall leans, and how the glass pattern will compensate.
• Backing check — confirming solid material where hinges or channels will anchor, especially for heavy frameless doors.
• Swing and clearance — the door's arc against toilets, vanities and towel bars; this is where some projects convert to a slider.
• Hardware and glass finalization — finish, handle style, coating, and glass type are locked, and the quote is finalized from the real numbers.

For complex panels — notches around benches, angled ceilings, very out-of-square openings — the installer may build a physical template of the panel shape. That's craftsmanship, not delay.

Stage 4 — Fabrication: cut, polish, temper

At the fabricator, each panel is cut to the template, edges are polished, and hinge/handle holes are drilled — all before tempering, because tempered glass cannot be cut, drilled or ground afterward without shattering. Tempering is what makes the glass safety glass: if it ever breaks, it crumbles into small dull pieces instead of shards. This sequencing is why a wrong measurement is expensive (a panel is remade, not adjusted) and why installers measure so carefully. Typical fabrication time is about one to three weeks depending on complexity and coatings; your quote should state the expected window.

Stage 5 — Installation day

Installation is normally one visit of a few hours for a standard enclosure. The crew sets any channels or clamps, hangs fixed panels, mounts and aligns the door, adjusts swing and clearances, fits sweeps and seals, and applies silicone at the joints that need it. Expect drilling into tile for anchors — this is normal and planned for. A careful installer will operate the door with you, check the reveal (the gap lines) together, and explain the cure time before leaving.

Stage 6 — Cure, then care

Silicone needs to cure before water hits it — commonly 24 to 48 hours; your installer gives the exact figure. After that, care is simple and mostly about water spots: a quick squeegee after use is the whole secret, coatings or not. Avoid abrasive cleaners on glass and coated hardware, and check hinge and handle fasteners once in a while — heavy doors appreciate it.

Where this fits in a full remodel timeline

Sequenced honestly, a bathroom remodel runs: demolition → rough plumbing/electrical → backer and waterproofing → tile → glass measurement → (fabrication window, during which fixtures, paint and vanities finish) → glass installation → final touches. The fabrication window isn't dead time if it's planned — it's when the rest of the room finishes. Build it into the schedule from the start and the "glass delay" most people complain about disappears.
