About

Withamsville Winnelson is a full-service wholesaler specializing in plumbing. We carry a large inventory of high-quality products and serve a variety of customers, from general contractors to specialized technicians, and homebuilders to homebuyers.

As a locally owned company within a national organization, we offer not only the pricing and selection of a large supplier, but also the local decision-making and flexibility of a small business. We work hard to do things right, one customer at a time.

Founded in 1997 with a staff that collectively offers more than 50 years of knowledge, our team shares your get-it-done-right attitude and can get you the parts and equipment you need.
