my sister's house (no mansion, just a recent build) has double sinks in the master bedroom. the layout(s) of the bathrooms house-wide are annoying to me. it seems all new builds are just large for largesse rather than utility; laid out more for the listing than for use.
it's a 4 bedroom 4 bath house. upstairs, the master has its bath complete with two sinks like post (toilet is relegated to a weird claustro-closet). one of the sinks in her bathroom is a junk drawer ha!
The other 3 bedrooms: one has its own master bath and shower, and the final two bedrooms have a shared bath n' shower set between them. none of these bathrooms are accessible from the hallway, you must go thru a bedroom to do your business.
there is one "public" bathroom on the main level....now lemme talk about that stinker.
This damn thing is a half-bath, set right between the kitchen and living area. i don't know how the architect managed it, but it is somehow accoustically perfected to deliver your performance to the rooms nearby where everyone's tryina hang out.
Exaggeration? Not even. Like, forget stealth mode, you need a battle plan with flawless execution. You think things are going well? One slip-up and the people watching tv or chatting will be interrupted by your public broadcast. The noise is seriously noticeable.
No, I'm not scatalogically shy, nor do i possess super-hearing. It's a problem. A bad enough problem she eventually had another bathroom installed basement-level so guests might poo without detailing exquisitely to everyone what they ate that day.
