Shower glass backing and anchorage before tile checklist

A pre-tile shower-glass checklist for approved enclosure type, door swing, panel dimensions, wall and curb backing, waterproofing-safe attachment zones, concealed utilities, edge distances, blocking records, and installer coordination before tile removes access.

6 items to check

Inspection progress0 of 6
0%

Glass type, panel lines, door swing, hinges, clamps, and support locations are defined

Critical item

The enclosure concept should be sufficiently developed to locate structural backing and avoid conflicts.

Wall and curb backing is continuous and suitable for the selected hardware

Critical item

Blocking and framing should transfer enclosure loads without relying on tile, backer, or hollow anchors alone.

Backing and future fasteners are clear of pipes, wires, valves, and membranes

Critical item

Attachment zones should avoid concealed services and unnecessary waterproofing penetrations.

Any permitted fastener penetration has an approved waterproofing detail

Critical item

The system should define sealant, hole preparation, fastener, and prohibited locations.

Walls, curb, and jambs are framed to support the intended glass geometry

Substrates should be sufficiently plumb, straight, and stable for hardware adjustment and seals.

Blocking and no-drill zones are documented for the glass installer

Final installation should use an accurate concealed-work record.

Use before backer and tile conceal framing at shower glass attachment locations. Final glass engineering and fasteners remain the glass installer’s responsibility. Inspect from the room, accessible framing, and dated stage photographs. Do not energize exposed electrical work, pressure-test systems without authorization, or walk on uncured waterproofing, mortar, or heating assemblies.
