The bathtub is identical to the feed trough. However, it does not have any special properties, thus it can only be used for decorative purposes.
Brahmin feed troughs can be placed anywhere there is sufficient space, but it's most useful to place it somewhere out of the way, so brahmin aren't blocking others.
The brahmin feed trough is located under Resources → Miscellaneous while the bathtub is found under Furniture → Miscellaneous in the workshop.
Brahmin feed trough
The brahmin feed trough and bathtub can only be crafted at a workshop.
- A feed trough appears to support up to two brahmin, so a settlement with three brahmin and one feed trough would likely have two brahmin by the feed trough, and one wandering around.
- Pack brahmin and caravan brahmin do not pay attention to feed troughs.
- The brahmin eats from the left side of the tub (when looking at the tub longways with the faucet side closest to you).
