The medbay is a room that can be built in Fallout Shelter.


The medbay is a production room that unlocks at a vault population of 14 dwellers. Dwellers will produce stimpaks in them. Medbays also extend the vault's storage capacities for Stimpaks. Medbays depend on the Intelligence trait of the dwellers working in it.


Single Room Double Room Triple Room
Output 1 3 4
Upgrade Bonus 1 3 4
Clinic Upgrade Cost 1000 1500 2000
Hospital Upgrade Cost 3000 4500 6000
Stimpak Storage Capacity 10 (+5 in the first room) 20 30

The output of 3 upgraded double rooms is higher than the output of 2 upgraded triple rooms. The storage capacity and the used space in the vault is the same. That means 3 double rooms are more efficient than 2 triple rooms.
