Toilet model, rough-in, clearances, and parts are compatible

Critical item

The fixture and installation components should match the existing rough-in, drain, water supply, room clearances, floor condition, and required listing or efficiency criteria.

Closet flange and surrounding floor are sound

Critical item

The flange, drain connection, fastener support, and surrounding subfloor should be sound and repaired with an approved method before the toilet is set.

Bowl is sealed, supported, and securely anchored

Critical item

The selected seal, bowl setting, shimming, fasteners, torque, and base treatment should follow the fixture and seal manufacturer instructions without cracking the porcelain.

Supply, fill, flush, and drain functions pass repeated testing

Critical item

The shutoff, connector, fill valve, tank hardware, bowl connection, and drainage should remain watertight and operate as intended through repeated cycles.

Shutoff access, finish, cleanup, and documentation are complete

The shutoff should remain accessible and operable, adjacent finishes should be undamaged, and removed fixtures and waste should be handled as agreed.

Use this checklist after a toilet replacement and before accepting the work. Local plumbing rules, product listing, manufacturer instructions, accessibility requirements, and permit requirements control the final installation.
