Hick was originally planning a half-bath for Bedroom 2, and a full bath for the rest of the house, taking up a section of the living room. The more he looked at the windowed area off Bedroom 2, where he'd intended to make a closet/half bath, he thought he could fit in a shower as well.
I only have a couple of pictures, since I didn't walk into that room on my original tour.
This picture is taken across the enclosed back porch, leaning out the doorway with my back to the master bathroom, beside the future utility room. You can see the window that will remain in Bathroom 2. Hick plans for a toilet under that window, a corner shower by the framed wall and back wall, and a sink on the wall that's against the bedroom.
Here's the other view, across Bedroom 2:
I agree that a full bathroom is a better option for Bedroom 2 than a closet/half bath combo. Anybody living in that room will not have to traipse out to the main living area to bathe, but can have their own private shower. Not that The Pony is planning on a roommate, but for future rental or resale scenarios.
Today, Hick and The Pony are meeting for lunch, and browsing through Lowe's or Menard's afterwards, to measure jetted bathtubs and showers, and discuss prices and The Pony's preferences.
Hick is chomping at the bit (The Pony, not so much) to get "his people" into Pony House to check out heating and cooling options, and drywall estimates. As soon as he's sure of where the walls are going for sure, Hick will finish the wiring. He's already been fiddling with the windows, and needs some assistance with the back wall, since HOS (Hick's Oldest Son) has come down with a concussion, and is not currently available.
