I'm buying a home with a horrible master bathroom layout. See the included photo with the sink open to the bedroom (and the carpeted floor). The sink is 60". Through the door are the toilet and shower. That area of the bathroom is 60" long.

I want to tear out the wall separating the sink from the toilet and shower, put in a 48" shower with glass on two sides, install either a 66" or 72" double-bowl vanity (two 24" base cabinets with either an 18" or 24" three-drawer cabinet between the two) and a tower cabinet on top between the sinks, and add a wall with a door to separate the entire room from the bedroom. The gap between the vanity and the shower would be either 4.5" or 10.5" depending upon the width of the center cabinet I choose. I'm thinking 10.5" would provide a useful gap but the 4.5" gap would be wasted space. What do you think - prioritize more counter & cabinet space or a more functional gap between the vanity & the shower?

When I add the wall, I really want to install french doors. I feel like they should swing into the bathroom since the bedroom isn't the largest (there would be 11' from the bathroom door to the opposite wall. Since they would lead to the entire bathroom, I want them to lock so would have a flush bolt at the top of one door, then a privacy knob on the other. I can't find the "perfect" french door set so I would fabricate one by combining two slab doors of my choosing. I'm thinking two 24" slab doors would be my top pick, making for a total 48" opening if both are open, but 24" if only one is open. Should I instead opt for two 28" doors so you have a normal-size opening when only one door is open? I have the option to install a standard door but I like the idea of the french doors leading to the bathroom.

The floor will be completely tiled with the shower surround done in the same tile (12x24 size). Grey will be the predominant color but the tile does have some neutral color. I should add that this house is intended to be a flip home so once renovation is complete, I will sell the home. I need the option that will likely be the most attractive to the next owner. Considering this, is the french door option too risky of a move?
