For the next five years, overall demand for plumbing fixtures and fittings in the United Sates is expected to rise 2.4 percent per annum to an estimated $10.9 billion, according to an April study from The Freedonia Group Inc., a Cleveland-based research firm.

“Plumbing Fixtures & Fittings” reports that the advance can be attributed to the acceleration of the repair and improvement markets, as well as a rise in new nonresidential construction expenditures.

Consumer trends toward larger kitchens and baths, as well as the drive of fashion-conscious homeowners, will aid replacement demand as new finishes and product technology is introduced.

Plumbing fittings demand is expected to climb to just over $5 billion in 2010, fueled by growth in lavatory, bathtub and shower fittings.

Regionally, the South and West will experience income gains, ultimately supporting increased spending on plumbing products in the residential market.
