Can the K-304-K valve be used to control the shower head only?

I am installing a shower without a bathtub and intend to cap off the lower exit port which feeds water to the tub, so that the shower head only recieves water. Is this okay to do or do I need a shower only valve such as the Kohler K-2972-KS?
Asked by: Anonymous
NO.But you can renovate pipeline to control the shower head only.

Rite-Temp Pressure-Balancing Valve is rated 4.3 out of 5 by 27.

I installed this valve 6 or 7 years ago, and am now ordering a replacement for the third time. The rubber proportioning seal does not hold up very long, resulting in a dripping shower head. It would be nice if Kohler sold only the rubber seal--that's the only faulty component--but you have to buy the whole assembly, then throw away most of the assembly including the nice brass housing.

Rated 1 out of 5 by from This was exactly the same part number as the shower... This was exactly the same part number as the shower valve I bought in 2008, but it does not have the threads to attach the handle. I used the pressure balance unit, which is supposed to fix the drip from the shower head, but it still drips about every 3 seconds. Did not fix the drip problem. Useless

Rated 3 out of 5 by from Some good features The plastic trim ring has raised guides for 2x4 blocking which helps with the placement of the 2x4s, but there is movement of the valve in the trim ring and no means of directly attaching the valve to the blocking so extra care in securing the pipes is required. The position of the trim ring when attached to the blocking leaves just enough room for female adaptors to be screwed on to the valve outlet/inlets. The installation instructions are poorly written, are completely unclear in reference to several steps of installation and are severely lacking in explaining/picturing the attachment of the plastic ring to the blocking.

Rated 5 out of 5 by from Built well with installation bugs Product had engineering issues which required a valve stem extension to connect face plate and handle. Part was available through Kohler at n/c, however; delayed installation due to availability of part (back orders).

Rated 5 out of 5 by from Excellent purchase! I purchased this valve because I wanted a specific trim kit. I read several reviews on other valves and decided on this one. Installation was easy and no adjustments were required. It was perfect for me right out of the box. The mounting of the valve may be a problem for some unless you're familiar with the ins and outs of plumbing. But then, if you aren't, you probably need professional installation anyhow. I did have to contact Koehler for the dimensions of the hole to drill for a shower stall installation as the details weren't really all that specific. I heard back from their Customer Support folks within 1 day and provided the proper size (4"). The trim kit I had selected installed easily and looks beautiful.

Rated 5 out of 5 by from A very well built valve This valve installs easily and solidly, and is very well built. 4 mounting screws puts this valve in place for a very rigid installation, unlike many other valves. And it allows you to install a lot of different styles of Kohler trims later in the construction process. I use PEX plumbing in my homes... installation of this valve is very quick and maintenance free.
