American Standard 066078-0070A – Frequently Asked Questions
1) What is the American Standard 066078-0070A deep rough-in kit used for?
It is the deep rough-in kit for American Standard R700 Series thermostatic and volume control valves. The kit extends the valve body setting so the trim still lands correctly when the valve sits deeper in the wall than standard, which is common with thick tile, stone, or furred-out shower walls. Order it by manufacturer part number 066078-0070A.
2) Does this deep rough-in kit include the valve itself or the shower trim?
No. The 066078-0070A is a deep rough-in kit only, a repair/service part for R700 Series thermostatic and volume control valves. The valve body and the finished trim (handles, escutcheons) are separate orders, so specify those alongside it if you are building a complete shower.
3) Will this deep rough-in kit work on an American Standard shower valve that is not an R700?
It is specified for the R700 Series thermostat and volume control valve, so identify the valve body in the wall before ordering. If the cartridge and body are from a different American Standard series, this extension kit is not the right part for it.
4) Is the American Standard deep rough-in kit metal or plastic?
Brass. The kit is brass construction, so the extension components hold up in a wet wall cavity and take handle torque without deforming the way a plastic extension can.
5) Why does the R700 kit only come in NO FINISH?
Everything in the deep rough-in kit sits behind the wall, so there is nothing to plate. That is why it is offered in a single unfinished version, part 066078-0070A. Your visible finish is decided entirely by the R700 trim kit you pair it with, so it will match whatever finish you have standardized on across the other showers in the building.
6) Can a maintenance tech retrofit this kit into an existing R700 shower without moving the valve?
That is the point of it. Where an R700 valve already sits too deep, either from the original rough-in or from a tile or panel build-up added during a remodel, the deep rough-in kit lets the trim reach the valve instead of tearing out and relocating the body. It is stocked as a repair part for exactly that situation.
7) How much wall depth does this American Standard rough-in kit add, and how big is it?
The kit is listed at 10.433 by 4.1 by 1 inches and weighs 0.271 pounds, so plan the stud bay and access opening around a slim extension assembly rather than a bulky valve body. Set the valve to the depth your finished wall requires before closing up.
