Preserve the useful detail
Record model, rough-in, supply stop, bowl and tank behavior, floor condition, seat height, leak location, and nearby drain response.
The decision on display
Do not transfer the hazard
Stop flushing if water rises elsewhere. Do not remove the fixture before the full scope and any permit or disposal requirements are clear.
Make the proposed work comparable
Compare repair parts with fixture removal, new connection, flange allowance, floor protection, setting, disposal, and operation testing.
