Relatively speaking, this method is the most reasonable. Just don't bathe on the wall between the bathroom and the bed. If the shower is hung on this wall, it is best to make this wall waterproof at least to 1.8 meters, otherwise it is easy for moisture to slowly invade the bedroom. It is recommended to buy a bed with a high backrest.
The bedside can't be close to the window or door, only in this way, and there will be no suffocation when separated from the bathroom wall. The only thing to pay attention to is moisture.
I hope it helps you.
