AMERICAN SANITARY PLUMBING MUSEUM

39 Piedmont St., Worcester, (508) 754-9453. Open Tues. and Thurs. from 10 a.m. to 2 p.m.

This two story museum is a surprisingly enjoyable soul-cleaning display of the history of toilets, tubs, faucets, and plumbing tools and a reference library to cover every drip and overflow.
