COLORADO BASED. JUST LIKE YOU.

Plumbing & Heating Supplies | Water Heaters, Kitchen & Bath Products & More!

McMillan Sales is a Colorado-based, family-owned plumbing and heating supply wholesaler, serving trade professionals since 1960. Our staff knows plumbing and heating. Some of us are licensed plumbers.

Most of us have been in the plumbing and heating supply business for decades. We ask the right questions to ensure you get the correct parts the first time. Our focus is solving your supply needs with the smart, effective product solutions you want.

What’s more, we have 68,000 sq.ft. in our on-site distribution warehouse, conveniently located on Interstate 70 (Exit #277), and we have a delivery fleet with reliable drivers. We carry professional-grade, designer, value-based and even ‘vintage’ plumbing products, most of which are unavailable at big-box chain stores.

McMillan Sales: product variety, affordable pricing and the quality service of a family-owned store. Learn more at mcmillansales.com.

RESIDENTIAL

Whether you need whirlpool tubs and high-efficiency heaters that work well in high altitude for a single-family home in the mountains, closet-sized water heaters and value-priced yet modern-styled plumbing fixtures for multi-family projects, McMillan Sales has you covered.

We’ve supplied some of the biggest development projects in Denver, Aurora, Lakewood, as well as plumbing & heating projects from Cheyenne, Wyoming to Pueblo, Colorado and personally and professionally delivered to Vail, Colorado and beyond.

In many cases, we can direct-ship, saving you even more money!

From handsfree faucets and flush valves to industrial-grade, high-efficiency, STATE-OF-THE-ART commercial boilers, again, McMillan Sales has you covered.

We have Sloan, Crown/Velocity, gas pipe and more IN STOCK.
