I hate to ask such a basic question, but....
I'm about to install my new Delta R1000 rough valve. What size wood do you guys use for the stringer? By my arithmetic, it looks like it should be about 1.5 inches from the back of the studs. Shower framing is 2x4s, 1/2" permabase, Kerdi, 1/4" thick tiles. Does my math sound right?
I know the second one of these I install will be a piece of cake. But this is the first.
I guess you lost the instruction sheet already?
I have the instructions. After I found some stonger glasses to read the tiny print, they still seemed kinda cryptic to a first timer. Online is easier; larger print! But harder to carry to the jobsite. Then I guess I had a late night brain fart. 1.5 inches from the back of the studs = 2x4. That makes sense, Delta. And it worked out even better. The "similar threads" at the bottom of the page answered my next question about soldering into the threaded inlet and outlet.
All of these valves have a min/max on the rough-in. If it is installed with the finished wall between min/max or the rough-in plaster guard device, the trim will fit BUT, if you are at one end or the other, you MAY NOT LIKE IT! So, temporarily, put it together with the trim to see how much of the shaft/handle you want sticking out, then measure, and mount the valve there. There are LOTS of people here that have posted complaining about how it looks (not how it functions) because they didn't mock it up first. To the manufactuer, if it fits, it's right. To the consumer, they usually, don't like it at either extreme. The engineer's version of min/max may not meet the fashion design sense of the user. CHECK IT FIRST!

We do not use metric in the USA. But if we did 7 cm would be easier to read on the ruler. When installing any recessed valve, you measure from the "face" of the finished wall back, because that is the only "positive" measurement you have.

W/ delta, better to be too deep or too shallow (if you gonna mess up). I've installed extension kits when valve too deep or tile changed at last minute but have never had to correct one too shallow. I guess the only solution would be to reset the whole body?
Delta give you 1/16 or so to play w/ on the normal trim kits? tia
