Real feedback from plumbers, facility managers, and homeowners across the United States.
"Just what I needed. Needed new drain for shower. Local bigbox hardware store only had fine thread fittings. This one is coarse thread and matched existing."

Verified Master Plumber • North Carolina
"Great experience. My shower drain assembly is 21 years old. I just needed the top piece. Big box stores did not carry the part. The drain fit perfectly and was easy to install. A link to an instructional video was included in package and was helpful."
