Thanks! I plan on asking the plumber but I come to these types of forums to get ideas and info so that I can gain knowledge from people with different experiences. I am the contractor (homeowner) with very little experience as you can tell with the plumber doing all the rough in and laying the 36 x 36 shower base.
The tiles are 8 x 12 with 1/8" spacing. The handheld has no bar, I am using the 59" hose, the Grohe swiveling handheld holder and I am using a Moen mixing valve/trim, no other valves. No soap holder, will be building a niche in the shower.
I am using the existing studs, the old shower faucet which is 2 handles - hot and cold - is not quite center but there is a stud which is almost in the center that the original plumber/builder notched when the house was built 40 years ago. Since we are talking about a small shower I would like the shower drain, center of the valve and actual shower head (not the holder) to be as close to in-line with each other. If I did the measuring correctly, the mixing valve should be able to fit in the notched area to achieve the center on the mixing valve with the output for the shower being able to clear the stud.
My plan was to offset the 90º "L" where the water comes out on the same wall as the shower plumbing toward the back wall and somewhere between the shower head and mixing valve, not sure about the geometry of just where yet. I'm not sure if there is a formula for this but don't know if being a equal height with the shower head or holder is the way to go, split it into 1/2 way or use the odd number rule that seems to be the designer rule. We did a dry "fit" yesterday and it seems that the hose will be looping in front of the shower controller which may be unavoidable in a small shower.
At this point I am the tallest person who will use this shower and I'm 6' tall. There will be a shower door installed, based on my internet research I am guessing it will be about 6' high and when that is added to the shower base curb I know it will be somewhere higher in relation to the shower floor.
We are trying to think this project through but maybe we are over thinking it!
