Kohler K-2972-KS Reviews

Rated 5 out of 5 by from Sturdy Valve Although I cannot speak to the performance yet, the quality of the piece seems top notch. It is a solid brass construction, and it seems to mate well with the trim piece. I was immediately impressed with the quality of this valve. No flimsy plastic here.

  • Which valve goes with the K-2972-KS - the K-T16175-4A or the K-679-KS-NA - I WILL be using the K-681-K to control volume.

    A. The Kohler K-2972-KS is a valve not a trim. If you are ordering the K-T16175-4A trim you will need a k-669, k-670 or the k-671 valve.
  • what is the difference between this and the K-679-KS which you dont seem to carry anymore?

    A. The Kohler K-2972-KS is the manufacturere ordered replacement for the 679-KS, which has been discontinued. They function with the same efficiency and power but has been redesigned with a new up to date shape and casing.
  • Is this the proper and only valve option for K-T16175-4A?

    A. The Kohler K-2972-KS is for 1/2" piping which is more commonly found in remodel situations or in system that do not require as much waterflow. For multi outlet systems where your plumber is using 3/4" plumbing you would use the K-2975-KS.
  • Can this valve be used to provide water supply to both a shower head and body jets?


    The Kohler K-2972-KS is a thermostatic valve and only adjusts the temperature of the water.
