Career switch: Sorensen got into the lucrative business of floral urinal making after spending years in costume design and computer graphics.
The sculptor and craftsman has attracted much international attention as one of the world's most creative manufactures of luxury urinals shaped like flowers and plants.
A graduate of the University of Utah with a bachelors degree in sculpture, Sorensen, 54, had spent years in costume design, illustration and computer animation.
Flush with customers: Sorensen, who so far has created more than 50 unique urinals, can hardly keep up with the growing demand.
Speaking to San Francisco Chronicle in his Mission District basement studio, Sorensen lamented that he is inundated with orders from all over the world and has been struggling to catch up with the growing demand.
Each flower-shaped bowl takes several months to sculpt out of clay. Once the model is ready, Sorensen bakes it twice in a 2,300-degree oven for two days, during which time the urinal can crack, forcing the artist to start from scratch.
Creative space: Sorensen makes his fancy pissoirs in his basement studio in San Francisco 's Mission District. One day in 2002, the artist was in a men's room when he was struck by an idea to transform the mundane, boring urinal into a whimsical objet d'art and even a status symbol.
With journalists and curious visitors queuing up to take a peek at Sorensen's porcelain sprays, his studio has been flush with business.
Sorensen's fanciful daffodils, hibiscuses and orchids have been exhibited in galleries from Hungary to South Korea, while deep-pocketed homeowners and businesses have been willing to shell out anywhere between $6,000 to $20,000 on his functional artworks.
Ouch! This Venus Fly Trap urinal comes with a $11,500 price tag and a full set of spikes, but fortunately for its future users, they are made of silicone rubber.
While most of his artworks imitate plants or blooms, Sorensen has created a few novelty pieces, including a controversial urinal shaped like President George W. Bush in 2008.
Over the past decade, Sorensen and a pair of assistants have wrought about 50 fully-functional, one-of-a-kind urinals.
The artist boasted that his most popular design, the orchid, has no splash-back during use.
In his studio, the 54-year-old has three such urinals, all of them fully plumbed in case customers would like to take them for a test run before pulling out the checkbook.
