rough in value

from Charlotte, NC – Verified Buyer

This is exactly what was needed on my bathroom project. It appears that when buying the Grohe line, you may need to pick up individual parts of the system. It was easy for our contractor to install.

Great product that matches the description!

from Fairfax, VA – Verified Buyer

Our plumber used this to install our new Grohe shower faucet. Don't believe he had any trouble installing and we have had no issues with the faucet at all.

long lasting valve, great lead time

from chicago, IL – Verified Buyer

The valve was purchased and shipped in less than a week. The valve is solid and allows the plumber some flexibility in rough in location and finish dimensions.

Who knew

I had no idea that when purchasing new fixtures for my bathroom that I also needed to get something called a 'rough in'. This was just what my plumber needed in order to hook up my new grohe rain shower head.
