The same if you have jsut 2 people in the 3 square room. If you have 4 dwellers training in a 2 sq or 3 sq room the training time is always going to be the same. You won't notice difference for one dweller alone in a room of any size. Yes, there is difference, but you forgot how it works - it's affected by amount of DWELLERS training together in the room.

I just upgraded the room myself and the time left of 17h 18m did not chance.

There is no difference between a 2 square room and 3 square room in training time. Only do it after you have 6 dwellers with max hp and legendary weapons spare.Ī late game vault will have 80-120 dwellers, 200 is only if you are going fancy. If you decide to make some dedicated resourcemaking floors.Ī door-elevator-storage-overseer ground floor can be good to stop raids on the groundfloor because the raiders will be forced to go trought the storage floor twice, put your guards here. There is an argument to put 3-2-3 floors with radaway/medpacks on the middle, if you have some auto colect robots. There are some stuff you can do to make a better late game vault, that uses 2 sized rooms, remove the second elevator on the ground floor, make dwellers not evolve some of the stats, etc.īut by the time this techniques are good, you don´t care about the marginal increase in profit anymore.

When you reach endgame, you start to profit from having smaler (2sizes) medpacs and radaway production. Tl dl: All the rooms are better at 3 size.
