Sanitation

Your civilization's sanitation will increase slowly as the eras progress, with major leaps in progress from constructing certain buildings.

Ancient Era
Sims do not have much by way of clean water at the start. Bathtubs may not exist on the home lot, and you are limited to two bushes(outhouses are acceptable if you don't have Get Together). Swimming pools are allowed, but may not contain clean water.

You may unlock real toilets(and more than two), and bathtubs on the home lot by completing woodworking crafts.

Classical Era
No changes.

Buildings
Classical buildings that improve Sanitation:
