  • The Pfister 0X8-310A is going to be 3 5/8" wide and 3 3/4" tall at the male end and 4 13/16" at the female end. The finished wall needs to be 2 5/8" minimum to 3 1/2" maximum.

    Will this valve fit inside a 2x4 wall? If not, what valves (for a shower only) will?

Rated 5 out of 5 by from good valve This is the second valve of this type I've installed and it works as it should. It is a good value and would recomend it to anyone considering a new installation or just replacing a old valve during a remodel.

Rated 1 out of 5 by from Worst Quality Ever I purchased Price fister plumbing products based on looks and not quality. I find the quality very poor. I've had this valve replaced twice in less than a month and it still doesn't work properly. Yea, it's guaranteed for the life of the product, but it's poorly made and I don't recommend this brand to anyone, for any reason.

Rated 4 out of 5 by from This is a one piece replacement for two parts. The installation was easy and I am able to adjust the water temperature again. I find that this valve is slightly harder to turn than the original.
