I dont see your picture, but you ask an important question. I would be sure to carefully read the instructions for the shower control valve. Some units have the diverter function built into the valve and it is not a problem. What material are you going to use for the tub and shower pipe? PEX is often a problem as it is slightly smaller diameter than copper. More often the problem we see with pex on the tub outlet is that the slight restriction on the tub drain forces some water to dribble out of the hand spray if it isn't high enough. If your water pressure is too high this also can happen. You could build the discharge line for the handspray higher than you need to and then back down to the outlet point. This is not ideal either as it will waste some water, dribble longer after use and have a longer lag for temperature adjustment.

 

When in doubt, do a temporary setup, install the trim for the hand shower and tub spout before you cover the walls. Make sure they discharge into a bucket or down the drain the way you think they will.

 

 

 

That is a fairly typical setup. I dont know what type of control valve you are going to use. Follow the cautions i addressed before. Take note of where your hand spray hose is going to rest, make sure it wont annoy you.

Just do your rough in piping, and test it before you cover the walls. No extra soldering required.

 

What brand of shower faucet are you using? From my personal experience and calling the factory, Moen told me that I cannot go below 48 inches. However, calling Delta, they told me that there is no restriction on the location of the shower head in relation to the valve set.

I would call the company and ask what is the absolute minimum you can locate the shower head from the center line of the valve set.

 

 

Yes it would, but wouldn't it be nice if you didn't have to?

 

Yes it would be nice but since the valve is already in I don't have much choice, this is the shower set and doesn't say minimum distance:

Moen Genta single-handle 1-spray tub and shower faucet in chrome is a good choice. We've installed it in our bathroom as well. We're also using another shower head from Delta.

We purchased 3 of these in June of 2017 as we started to build our new home. The first two worked perfectly. We finally set up the 3rd one in the summer of 2019 and there was almost no flow.

We knew the house had enormous pressure. My husband switched it out with all the other same faucets and narrowed the problem down to the shower head. He took the shower head apart and saw that there were plumbers tape and/or plumbers putty dough clogging it up.

He took a pocket knife and cleaned it out. Now the 3rd one works as good as the first two on a side (unrelated ) note he also found the water restrict-or and removed it. Without that restrictor governing the water flow, it proved too much pressure for our small shower so he reinstalled the flow pressure restrictor.
