For example, if you merge two radioactivity rooms together, the combined room will have the increased protection, efficiency, and capacity that was present in both rooms. When you merge rooms, their functions are combined into the newly created room. In Fallout Shelter, you can merge up to four rooms together, creating a larger room. How many rooms can you merge together fallout shelter? That’s why it is important to always make sure there is enough space in each room before you try to merge them. If one of the rooms is full with 6 dwellers, then it will not be able to merge with the other room that has 5 dwellers. For example, if you have a Science Lab and a Living Quarters, you cannot merge them until both of them become either Science Labs or Living Quarters.Īdditionally, you must also ensure that you have the correct amount of dwellers in those rooms in order for the merging to be successful. In order to merge rooms, both of the rooms must have the same kind of room. You could more out exploring (is the limit 25 now?), and have the rest (60-100 depending on your population) in crafting rooms.Ĭan sell the training rooms, theme production and barber for power saving if you want to be efficient and have room for more weapon production.īuild new nuke reactors as necessary if the crafting rooms use more power than the training rooms you are replacing.It is likely that your rooms are not merging in Fallout Shelter because they are not of the same type. In my vault the other 70 are in training rooms. replace all food and water production with Cola (but I won't for variety)ĭone efficiently, I think I need 5 resource buildings and 3 power buildings: 32 dwellers.Īdd 2x hospitals and 2x science labs: +16 dwellers.having better dwellers in water production and sell a water treatment plant.Power produced 184/min, power consumed 95/min.I have 3 power plants and 1 nuclear reactor to power it all

Food produced 110/min, food consumed 41/min.Water produced 86/min, water consumed 41/min.The NuKaCola, Garden, Purification Plant, Caffeteria, and 2x Water Treatment Plant give me more than enough food and water for 126 dwellers (I stopped collecting them as I can only do 3 quests at a time and my rooms don't need more).

Other than power, storage and accommodation, I have one of each room type.
