"Sometimes, particularly in an older home, it's easier for us to come inand re-glaze the tub than to replace it and have to rip out good tile work," said Kott.

What you'll find

The lower level of the Sugar Hill offices is a small showroom where buyers will find a selection of refinished tubs and pedestal sinks. "We get them from around the country, from homes being torn down and from people who just bring them in," said Kott. "We work with a broad network of people to find them."

Many of the old tubs arrive with chipped finishes and rust stains. Re-glazing gives them a new shine. Buyers also can have colors applied to the outside of the tubs. A refinished, five-foot tub costs about $795.

"Originally, the outsides of the tubs were black, raw cast iron," said Kott. "Everyone painted the outside what color they wanted and only the inside was white porcelain. Generally, they painted the bathroom whatever they painted on the outside of the tub. But we can do any color."

Along with tubs, the company re-glazes counters and cabinets and repairs tile work. Having one re-glazed at home is about $495.

The shop also sells antique plumbing fixtures made of solid brass. Prices range from $100 to $500.

Trends

More buyers are looking for the old-fashioned tubs to give flair to their new homes, said Kott. "They like that antique look, whether they're restoring an older home or moving into a brand new house with a 1920s look. And it's a conversation piece."
