Why choose Krowne?

Krowne is the nation’s most trusted provider of plumbing products for commercial applications. With over 70 years of experience, we have put a tremendous amount of time and effort into our products; every detail is carefully considered. We are a one-stop-shop where customers can find a variety of products allowing them to consolidate purchases and, ultimately, save the hassle of dealing with multiple manufacturers. We consistently have inventory in stock and ready to ship, allowing for quick lead times and, often, same day shipping! With our recent expansion, we have a new warehouse management system for streamlined order pickup processes, as well as new machinery, such as laser guided forklifts. This system allows for greater efficiency, as well as the ability to delivery producers faster than most competitors.
