WHAT OUR CUSTOMERS SAY…

“Outstanding fast delivery on two pieces of an ancient Wolverine bath stem for Kohler - from the early 40s I think. The new one has a different body design, but it screwed directly into the old hot/cold tree and was the exact 6" length. Forty eight hours after installation now, and all remains fine. Also, kudos to the people who set up the website and ordering process. Great work - clear photos and info ! PS: I'm not an employee or family...lol. I retired from electrical wholesaling here outside Chicago and I appreciate a good job. ”
