Welcome to Gateway Winnelson

Gateway Winnelson Company is a full-service distributor of Plumbing fixtures, parts and supplies for Residential and Commercial Plumbing Contractors, Plumbers, Commercial Institutions, and the General Public for the Greater St. Charles and St Louis area.

Conveniently located on 201 S. Cool Springs Rd. in O'Fallon, MO, off T.R. Hughes and Interstate 70 (EXIT 219), we offer you premium service, a wide variety of quality products, enthusiastic employees with in-depth product knowledge, a vast support system, competitive pricing, and top notch service.

Gateway Winnelson opened its doors in 1999 and is currently operated by company President Mike Lewis, who has over 20 years of experience in the plumbing industry. As a former plumber himself, Mike is also fortunate to have a highly capable staff of professionals, each with a unique, professional background in the industry. This means that no matter what you are looking for, our company has the people and resources to meet your needs.

While Gateway Winnelson is a locally owned and operated wholesaler, it is also part of a larger organization called Winsupply. Winsupply is a group of independent corporations held together by a central philosophy of opportunity, responsibility and pride. The organization provides a support and communication network for all of the Win companies.

When asked what makes Gateway Winnelson Company unique and different from the competition, company president Mike Lewis states "Gateway Winnelson is here for you, the client, with a wide range of products and services, and are increasing our inventory on a daily basis. For those of you who are familiar with us, you know: If you want us to stock or procure an item for you, we can and we will. Gateway Winnelson also offers unmatched customer service, with your satisfaction at the forefront of our daily operations. We pride ourselves in this fact of knowing your trust and respect in us is our greatest asset!

We look forward to building a strong business relationship with you.

 

Coming Soon

Gateway Winnelson is joining the HVAC industry, and will soon be offering top of the line HVAC products and supplies. In addition, we will be offering E-Commerce to all of our customers, which will allow you to save time by shopping online, check inventory levels and verify pricing. (Meaning you will no longer have to fax or phone us your inventory sheets).

We are excited to announce that we are building our new working showroom, which will be approximately 1,000 square feet, featuring a working TOTO Washlet Seat, shower heads, kitchen faucets and more. At Gateway Winnelson, we will be incorporating multiple screens, featuring videos from our top of the line brands, showcasing their features and benefits, with another screen rolling the history of Winnelson. In time, we will be adding a 3D virtual reality element to our showroom, allowing you to envision your existing space with a remodel.
