Welcome to Rosen Plumbing Supply Company !!


Rosen Plumbing Supply Company is the premier independent, family owned and operated plumbing and heating wholesale distributor in Western Washington. We proudly feature the top manufacturers of plumbing and heating supplies in our five branch locations conveniently located in the greater Puget Sound region.


Our trained staff of service professionals relies on their many years of industry knowledge to assist our customers with their plumbing and heating needs. We offer exceptional customer service and product knowledge in both the residential (new construction and repair & remodel) and the commercial plumbing and heating markets, as well as those hard to find service parts. Our dedicated team of knowledgeable, outside sales staff are continually visiting our customers to make sure our customers receive the service they deserve. We also provide job quotes and submittal and O&M manuals on all of the commercial projects we are awarded. Our state of the art quotation department can even put your submittals and O&Ms on a disk for easy data storage.
