Glam Ensuite Guest Bathroom

We have used Decorilla for my office and want to take on the bathrooms downstairs. As you can see in the floor plan, there are 2 bathrooms, one to be used for anyone, and another that is next to a bedroom that we use as a primary guest room.

We would like to move the door from the hallway into the bedroom so it's an ensuite.
Modify the shower to be a full stand-up shower vs the corner triangle that we have now. We want to maintain the existing locations of the toilet and vanity. The vanity is narrow.

Questions: We could move the shower to be on the wall next to the existing vanity since water is already there and we will be closing the existing door. This will also allow us to reduce the cost of the glass enclosure. My only concern would be turning on the shower and being blasted by cold water. A solution would be to have a tub spout closer to the ground to discharge... or keeping the shower controls exactly where they are but to put the shower spot and hand spray on the opposite side where the sink is.

In scope, floor tile, shower tile, threshold, wall tile/paint, wall color, vanity/sink/faucets, toilet, hardware, towel bar, lights,

Our house is currently being painted black and the master guest bedroom will be painted a Benjamin Moore Hale Navy blue and white. Please see the initial renderings of the guest room with the blue wall.
