 Integral stop shower valve needed?
Author: Anonymous User

My bathroom is stripped to the bare walls; the shower stall is stripped to its frame. You can see the two copper lines coming up out of the floor, going to the shower controls, then the one going up to the shower head.

We are going to reframe the shower (water damage), have a new shower pan and dam installed, then hardiboard the walls and have it all tiled.

It's been suggested to me that the best route to take would be to have a shower valve with integral stops installed before I do anything else. Then reframing, shower pan, hardiboard hanging, tiling -- can proceed with the least amt of attention required to water location, on/off, etc.

Is this what I should do? I want to do the right and best thing, but also don't want to do anything unnecessarily!

Thank you any and everyone for your advice.

Integral stops are a nice convenience in a single family residence where you can readily access the main shutoff. Builders will normally NOT use them because although the cost is minimal, the benefit is also minmimal. They are almost indispensible in condos or appartments where a main cutoff affects many families.

Thanks for the info; I have a very basic question now! The person who suggested the integral stop valve said it was bc I needed to be able to shut off the water while work was being done in the shower, over a 4 day period. So, rather than doing it via the main shutoff to the house, he said I could either a) have a valve installed where it could be turned off at the site, or b) have a plumber come in, solder the shower pipes closed, and then have the plumber come back and open/reattach the shower mechanisms once cosmetic stuff was complete.

Is this true -- that I have to shut the water off while all tile work is done? Can I get away with doing it via the main shutoff valve (as long as I've got some in buckets to allow flushing of the commode)?

I am completely confused by his comments. I always install the shower valve before the "cosmetic" stuff is done, and unless it is a valve that the mechanism is furnished later, in which case the integral stops are already fastened to the valve, the water does not have to be turned off at any time afterward, (and certainly not for the tile person), unless it is to work on the shower valve for some special reason. Integral stops are nice, except; (1) by the time you need to use them, they may be frozen and not functional, and (2) in a residence most valves can be serviced without removing the trim plate, so the servicing plumber might never see the stops anyway, since he would normally just turn off the main valve and do a conventional service job.

Stops are a good step when installing a badsci shower, when possible. They are available in straight or angle stops. They are designed to allow service work on the valve for short or longer periods withour having to shut all the water down in the bathroom.
As HJ, so wisely pointed out, if the stops are buried, covered or not used or tested annually like any valve the stems can seize making them useless.
It takes a wise person to make the final decision as to whether it applies to them ... or not.
Best Wishes

Where I come from, every fixture is to have its own independent shut off. For a shower this will either be shut off valves behind an access panel (hopefully in a closet or inconspicuous place) or integral stops behind the trim. Either way is acceptable. And all work should be installed and tested prior to the backer board being installed except for the trim plate and handle.

The stops may be a Local Plumbing Code requirement. Your plumber can answer that question. The additonal cost is minimal.

Here, each fixture is required to have shut off valves which means if there aren't hot & cold valves that control the whole bathroom group in an access panel or in another accessible location, integral stops are required.
