Is Thomas Crapper a saint

Answer 1

No, not yet at least.

Roman Catholic AnswerTo the best of my knowledge, Thomas Crapper was a plumber who had a firm in London from the end of the 19th century into the 20th century. Odds are pretty good that he was an Anglican and no non-Catholic has ever been declared a saint.

Answer 2

While many plumbers and users of Plumbing products may look at Thomas Crapper as an unofficial patron saint, he is not considered as a saint in the Catholic Church. Saint Vincent Ferrer is, however, considered as the patron saint of plumbers. He worked so hard to build up the Church that he became the patron of people in building trades.
