We have a rainshower head in our steam shower in our master bath and I have never had any issue with condensation dripping from it.

Oh shoot, just saw the new weigh-ins. John, I backed out of doing the curbless shower and am just doing a regular. It was stressing me out too much. I had too many worries and decided it wasn't worth it. The shower is the very last stop out of the house for all the drainage, and it's a private sewer system with a grinder pump. In the event of a clog or other plumbing issue, I didn't want to risk my shower getting backed up without a curb to help contain. I tried actually ordering a matching drain when I ordered the fixtures, but strangely they didn't have one. Then I forgot about it, whoops. Maybe it was the online retailer I used, but I'm searching now and still not finding a Delta shower drain in the Venetian Bronze, which is the shower hardware I ordered. I'd have to get something in another brand which wouldn't be an exact match.

A shower bench is a no brainer. The shower bench makes using the shower more enjoyable and does add to any romantic encounters you may have. If you have a wife like mine you better add two shower heads because mine steals all the water. I have a collection of shower bench photos that I show my clients to help pick a style. The shower bench detail can affect the placement of the drain so its wise to plan the build completely before picking or roughing in the drain.

Dream, In your original question, you were looking for a separate volume control. This allows you to control the volume of water coming out of the shower head. A theromostatic valve manages the temperature of the water. It allows you to set a temperature and just turn on the shower and the water will always be at that temperature. If you have a pressure change, in a thermostatic shower, rather than changing the temperature, you get less water but the temperature is constant. I am not sure why it would be more to install than a pressure balanced valve though. The functionality is in the valve and the installation is the same as a pressure balanced valve. The cost of a Thermostatic valve is more than a pressure balanced valve. I will post a video once I find it from a hansgrohe explaining the valve set up in the bathroom. I found it useful to understand the functionality.
