Quality is great. This is a must for the grohe system.

Very high quality. What you expect from Grohe

Such fast shipping, well packaged. Just what I needed while we're in "rough-in" stage at the build site. I didn't want to buy the entire finished fixture yet because it might get misplaced during construction. Thanks again, Wayfair for helping me out!

This product was just what our plumber needed to complete our project and it arrived quickly and packaged very well. Thanks Mayfair!
