Vanity supply leak at a shared wall: compare the bathroom and adjoining-room scope

01 / PLAN THE CONVERSATION

Create a two-sided room sketch

Draw the vanity and supply-line location on the bathroom side, then label the room on the opposite side of the shared wall. Add visible water, staining, swelling or finish changes only where safely observed. Note continuous flooring and baseboard runs, but do not extend the observed boundary through the wall by assumption.

Attach the discovery time and source-control record. A shutoff or plumbing repair can stop new water while leaving the condition of surrounding materials unanswered. Keep the repair invoice or statement with the file without treating it as a restoration assessment.

02 / PLAN THE CONVERSATION

Ask what cabinet access is included

A vanity can limit access to the wall and floor beneath it. Ask whether the proposal includes removing a toe kick, shelf, cabinet component or contents, and who is responsible for protecting or reinstalling those items. The wall-cavity access guide gives a useful way to record proposed openings and approval boundaries.

If access is deferred, require the limitation to be written. If access is proposed, ask what observation or measurement supports it, what area would be opened and how additional findings would be communicated before more work proceeds.

03 / PLAN THE CONVERSATION

Compare the adjoining room separately

List the adjoining-room finish, furniture or storage that affects access. Ask whether that face of the wall will be inspected, whether contents movement is included and whether floor or trim work stops at the doorway. A bathroom-only total and a two-room total are not comparable until these boundaries match.

Use the written estimate comparison guide to align extraction, access, drying equipment, monitoring, removal, disposal and repairs across proposals. Mark each line included, excluded, allowance or pending assessment rather than using a single check mark for the entire room.

04 / PLAN THE CONVERSATION

Require a written change path

The initial assessment may leave concealed areas unknown. Before authorizing work, identify who may approve an opening, how the price or schedule would be revised and which photographs or readings will be added to the record. Do not sign an open-ended change line.

Ask the responding provider to confirm availability, assessment charges and the written scope at your address. This comparison does not determine whether the shared wall is wet, whether removal is required or which trade should perform later repairs.
