There are two things that I feel need to transfer from interior hotel design to modern residential interior design.

First is the towel rack and shelf inside the shower. When I first saw this, it blew my mind. You hop in the shower, get clean, turn off the shower, and then you're all wet. Now what do you do? Simply reach up and grab a towel from the shelf. Dry yourself off and then hang the towel on the rack to dry. Then exit the shower. The current organization strategy of placing towels outside the shower is like hanging your knives on the wall opposite to your cooking space. Keep things in the places where they are most used.

I realize that some people may want to walk out of the shower and strut their stuff in front of the mirror for a while and then dry off after the narcissistic glow fades. If you fall into the category, I have no advice for you.

The second thing is automatic lights. In hotels, these are lights that shut off a few moments later if you don't have your room key in the electronic slot. This could be putting a RF/wifi token on your keychain. When there's no token in whichever room of your house, the device shuts off the lights to the room. When a token arrives in a room that previously did not have a token, the circuit is activated and it is possible for the lights to turn on.
