Scope of shower pan installation
Shower-pan installation is part of a coordinated drainage and waterproofing arrangement, not simply fitting a visible base. Supply the product, shower dimensions, supporting-floor details, and existing drain location. Have qualified providers define removal, substrate and support work, connections, waterproofing interfaces, testing, and the surrounding finish before the pan is installed.
Treat the shower pan as part of the waterproofing assembly
A shower pan may be a prefabricated base or part of a built shower system. Give the installer the selected product, dimensions, drain location and the planned wall assembly. The pan, drain connection, supporting surface and wall interfaces must be considered together. A tile finish alone does not establish that the underlying shower is watertight.
For replacement, describe leaks, movement or visible damage and ask what investigation is needed before selecting a new pan. Removal can expose affected framing or subfloor material. Establish who assesses and repairs those conditions and how changes beyond the initial scope will be approved. Plumbing and any required local inspections need explicit responsibility.
Coordinate the walls, enclosure and testing
Ask how the selected system's instructions govern support, connections, waterproofing continuity and any specified checks. Identify who returns the walls and enclosure to a finished condition. A pan-only quote may not include demolition, tile, glass or restoration of adjacent finishes. Compare offers against the same complete assembly and end condition. At handover, request the installed product information and a record of unresolved work; installing a base is one stage of constructing or restoring a functional shower.

Project questions
What information is needed before a shower pan is installed?
Supply the pan product, shower dimensions, drain location and supporting-floor information. Ask qualified providers to coordinate the drainage and waterproofing arrangement rather than assess only the visible base.
Does a shower-pan quote include surrounding waterproofing and testing?
Ask for removal, support, connections, waterproofing interfaces, checks and finishes to be identified. Agree on each provider's responsibility before the pan is fitted into the proposed shower.
