We have both and it’s awesome. Totally worth it. Wouldn’t change it at all. I think our shower is about same size too. Pic below. Brand we have is Riobel

Sorry it is wet it was just used lol

Here's what I did...handheld on the wall that extends to a small triangle seat in the back (shower is 32"x60"). So you can get both at the same time. These are Hansgrohe fixtures, details on request. Put on the shower head you want.

I’m not sure we would shower at the same time, but even so, I’m not sure I understand. I was thinking of the hand held shower head on one short wall and the rain shower head mounted in the exact center of the ceiling. Are you suggesting mounting the rain shower closer to the short wall the hand held shower is not mounted on?

If you look at my pic it’s nice to have them together. The rain shower and hand held can be used at same time or separately. I’m glad hand held can be used for regular showering easily. I would not separate them or make hand held on some lower wall.

We mounted a rain shower in the ceiling right in the middle, and our shower is 6' long. Our rain shower is by Jaclo, round and flat (like a frisbee golf disc), and 10" wide. It was about $250 for the fixture. Make sure to have a diverter installed. If you get a 3-way diverter, you can switch from the hand-held to the rain shower, or have both on at the same time.

I have a set-up like AJCN, except that hubby wanted a regular shower head and so his is on the end wall. I have my hand-held on the back wall a foot or so away from the wall with his shower head. This way, if anybody ever has to sit to shower, we have a rain head directly over a stool placed in the center of the shower and the hand-held bar can hold that at any convenient height just to the side. I can still barely reach the controls.

I find most wall mounted rain shower heads too close to the wall so make sure you measure that if going wall mounted.

I was planning to have it mounted on the ceiling.
