Assuming you are limiting yourself to the basics, that means at a minimum you will need one Weight Lifting room, one Armory and one Athletics room to train dwellers for power, food and water production.

If you wish to maximize production you will need dwellers with 10 in the appropriate SPECIAL attribute for each room. That is a total of 15 rooms.Īfter that, the numbers get kind of fuzzy, because production over time is based on the SPECIAL attributes of the people assigned to the rooms. If you don't mind some of your dwellers being on permanent coffee break and wandering around, you will not need that many rooms.Īt a minimum you are going to need five triple Living Quarters fully upgraded to take in 200 dwellers. This number includes the Vault Door but not the Elevators. If by accommodate you mean having a room assignment for each dweller, you will need 100 rooms total.

Well, the only required rooms in a vault are Living Quarters, Power Generation, Diners, and Water Treatment rooms in addition to the Vault door and Elevators to connect the levels.
