As a senior plumbing and mechanical inspector for the City of San Francisco I enforce the California Plumbing Code, (California adopts by incorporation, and amends the Uniform Plumbing Code, hereinafter CPC and UPC). Over the years, I have consistently been asked the question of how an owner can have a contractor install a “curbless shower” while at the same time meeting the requirements of the current CPC/UPC.
It seems as though many families want to follow the lead of our European counter parts and install showers sans curbs, dams, or thresholds. Or, on a more practical note, our aging population is adjusting to changes brought on by the aging process.
