This page of our guide to Death Stranding explains the additional use of the shower and toilet in addition to hygiene care. In this way, the protagonist can obtain unique items that can be used in battles against BTs.
In each private hiding place (a.k.a. safe house) there is a separate section with a shower cabin. You can do three different things in the washroom:
- Take a shower;
- Use the toilet while standing;
- Use the toilet when seated.
Each cabin has a unique function that automatically converts shower water, urine and feces into various types of EX grenades that can be used against BTs. After using the cabin, you will always witness a short cut-scene that informs you about the production of a new grenade.
It is worth noting that EX grenades are not automatically placed in the hero's inventory. When you leave your private quarters, you need to check your private locker and only then move the items to your inventory.
EX grenades can be used to lure BTs to change their location. As a result, they are much weaker gadgets than hematic grenades, which allow you to completely eliminate the attacked monsters. Nevertheless, using them may make it easier for you to pass through the locations where BTs are wandering.
