Investigation and replacement boundaries
Unused garden tub removal exposes the platform footprint and its concealed interfaces. Specify demolition of the deck, treatment of plumbing, floor restoration and the new shower's boundaries. A smaller shower does not eliminate the work needed to finish the area left outside it.
Set a hold point for concealed conditions
Document what is known before removal and what will be checked after access is available. Require findings and a proposed scope change before authorizing additional concealed work. The final assembly should be specified only with those findings accounted for. This is a substantial remodeling pathway; repair-only work, service calls and isolated maintenance are not established as accepted services.
What should be measured before choosing a base?
The room after accounting for platform removal, the drain route and any window or ledge that affects the wet area. The old tub's outer dimensions are not a complete installation measurement.
The owner should confirm the proposed service scope and provider availability independently. This guidance does not identify an approved contractor, establish coverage for a specific property or guarantee acceptance of the project.
The written scope is the reference.Use the provider’s proposal to record the accepted work, products, responsibilities and exclusions. Website examples do not establish an installation specification for your home.
