Seal the buckets and carry them to the surface as needed. Dwellers can be unassigned from rooms by sending them to the wasteland and recalling them at once.

Leveled up training rooms will probably kill off lots of low level dwellers in training. Disasters grow stronger in leveled rooms. It isn’t ideal, but it is an effective way to keep your shelter safe and sanitary. Don't level up rooms until dwellers have become tough.

Another option is to use small plastic toilets or buckets.

You may not be able to get clean, running water in an emergency, so you may need to install an expensive system of tanks, pipes, and filters if you want more comfort.

Many shelters do not feature running water, so a regular toilet isn’t usually an option.

You can also try joining the pipe to the air pump’s ventilation pipe. You may need to dig through the dirt so the pipe exits above the plastic canopy over the entryway.

To install the ventilation pipe, run it through the nearest entryway, if possible.

A good location for the toilet is near the exit furthest from your sleeping quarters. You will need to install a ventilation pipe, running it from the toilet to the surface. The most efficient way is a composting toilet, similar to what you would see in an RV. You have several options for installing toilets. Set up a toilet in a separate area of the shelter.
