What Is Henry Plumbing Supply Co Known For?
Established in the mid-20th century, Henry Plumbing Supply Coisn’t just another hardware aisle—it’s a full-service wholesale and retail destination catering to both professionals and DIYers. Located at 5400 South Kingshighway Boulevard, St. Louis, MO 63109, the company specializes in:

Why Choose a Local Supplier Like Henry Plumbing Over Big-Box Stores?
Many homeowners assume Home Depot or Lowe’s carry everything they need. But when it comes to older homes (St. Louis has thousands built before 1950), standard parts often don’t fit. Here’s how Henry Plumbing stands out:
For example, if you’re restoring a 1920s bungalow in The Hill neighborhood, you might need a compression-style angle stop valve—a part discontinued by national chains but routinely stocked at Henry’s.
💡 Pro Tip: Always bring a photo or physical sample of your existing fixture. Even small differences in thread pitch or flange size can cause leaks.
