Project Source warranty for toilets & bidets

45/100 Warranty ScoreRanked 4 of 13 brandsCheck your model's manual
The short version

Project Source doesn't cover everything, but keeps toilet (china) and tank trim and parts covered for life. That full coverage is the same as most of the 13 brands we compared, which typically cover nothing in full. You don't need to register to get this coverage.

From Project Source's published warranty, checked October 2026.
