i could do, but i don't really have problems like that in my bases and very few people mention it being a problem, the need actually already runs very slowly compared to other needs and the act of using a toilet only takes a couple of seconds, do you have small restrooms spread around the base so they always have somwhere nearby to use or do you have big central public restrooms?

I could probably use one or two more. I have 2 per gender for 20 colonists.
