No, people aren't actually standing under a shower head cleaning themselves with concrete. But a shower stall made of concrete is becoming a popular commodity, says Hugh Miller, owner of Concrete Coating and Resurfacing.

Miller's company does both interior and exterior coatings, but 80 percent of the company's business is interior work, Miller says. And 20 to 30 percent of that is shower coatings.

Two years ago, a customer in Lewiston, Idaho, saw Miller's work at a home show and approached him to create a concrete coating for a shower and separate tub surround.

The project took Miller three days to complete. The shower itself was a walk-in shower with a 6 foot by 7 foot floor and two 9-foot walls. The two other shower walls were glass, so Miller had to apply the coating on the support column between the glass walls. This posed a small challenge. "Because it's so small, it's hard to get a good texture on it," Miller says. The ceiling above the shower was also coated.

Miller placed a cementicious backer board over all the areas he was coating. He then placed a rubberized membrane over all the seams before coating.
