Shower Enclosure Installation Tolerances: Build a Field-Ready Approval Pack
Short answer: record the finished opening, wall plumb, tray level, glass dimensions, channel position, adjustment range and seal condition before the enclosure is closed up. The pack turns a catalogue size into a verifiable installation.
Use the same reference points in the drawing, site sheet and handover photographs.
| Hold point | Evidence | Release question |
|---|---|---|
| Finished opening | Widths, heights and diagonals | Is the opening within the model range? |
| Tray level | Long and cross readings | Will the door sweep and seal behave? |
| Channel | Fixing line and substrate | Is the load carried by the intended structure? |
| Glass | Pane identity and edge condition | Is the correct pane undamaged? |
| Water test | Photos and result | Is the observed water path acceptable? |
Keep assumptions visible
State whether measurements are before or after tile, trim and sealant. Record any deviation and its approved disposition. A redline drawing is better than a silent site adjustment.
Buyer FAQ
Who should sign the tolerance pack?
The parties responsible for the tray, enclosure, installation and project acceptance should agree the responsibility split.
Can photographs replace measurements?
No. Photos support measurements; they do not show every tolerance.
When should the pack be closed?
After final water and door-operation checks, before handover.
Continue the decision
Use the adjustment range as a limit and check the tray interface.
