The shower valve is the most important piece of plumbing in your bathroom you never see. In a nutshell, a valve is the brass component in the wall that makes everything work; it directs hot and cold water to the correct handle and pulls water from the spout to the shower head.

Valves can come equipped with valve stops, which are a huge benefit and convenience because if you need to check a leak or you’re ready for new handles and a new spout, you can turn the water off right there instead of shutting off the water to the whole house.
