Faction Housing Overhaul - Vault 81
We don't want to spoil anything but qhen you finish the main quest in Vault 81, there's a chance you'll be given your own personal quarters inside the fault. The vanilla version comes with a bed and a few other items but not much else. Faction Housing Overhaul - Vault 81 changes that.
The Faction Housing Overhaul - Vault 81 mod turns the room into something you can be proud of. The mod installs racks for magazines, tons of storage, a gym, a laundry room, a shower area, and even workbenches for crafting.
It's a dramatic change and it doesn't require much effort on your end. Check out the video below for more information.
Alternatively, if you'd rather overhaul Vault 81, your Prydwen Quarters and the Institute Director's Quarters you should check out this all-in-one overhaul mod on the official mod marketplace.
