Max and Sara Rosen founded Rosen Plumbing Supply Company in 1946 in Tacoma, Washington. From the beginning, Max and Sara understood that customer service and hard work was the best foundation on which to grow their business. Over the decades, Rosen Plumbing Supply remains locally owned and operated by the Rosen family, and continues to grow based on that simple fundamental principal - excellent customer service and hard work.

Throughout each of our locations, we feature the world's leading manufacturers of plumbing and heating supplies. Customers at Rosen Plumbing Supply have come to expect quality products at competitive prices and unparalleled customer service. We welcome the opportunity to provide you with all of your plumbing and heating needs. We look forward to seeing you at one of our branches or showrooms.
