Behind the Shower Door

If your retail business is tied to the declining residential real estate market, it pays to listen to the shower-door guys.

That's Bill Daubmann, 51, who with his two sons Keith, 29, and Douglas, 23, own the license to Mr. ShowerDoor stores in Florida. The company, which makes and installs shower and tub enclosures, operates two stores in Naples and Fort Myers and is opening another in Sarasota. Two more are planned for the Tampa area and Daubmann is thinking about adding a Cape Coral location.

The elder Daubmann has experienced two severe real estate downturns with the company in the northeast. His advice to other retailers boils down to this: Focus on what you do best.
