does any one has crews that are hygiene conscious and dont like to be dirty? who are toilet trained?

I have never had any problems like that with my sims, you can just take control of the other sims and make them bathe etc.

It depends (lol) i built my shelter on volcano overlook where there r springs. so if the sims need a shower, they have a dip in the springs. (hygiene problem solved)

Concerning the toilet problem, the sims use the toilet paper rroll by themselves when its urgent^_^

I am such a cheater, so I used all the cheats and built a lavish cabin on the first island, before I did anything else, and shower and toilet. Because my Sim uses the motives cheat I have no problem with using the toilet, but a few games before I realised about cheats, I always used to make my fly-surrounded stinking Sim wade her way in the the sea. Normally then unless I was on a real gathering/exploring/taking-care-of-my-neglected-sim spree, in which cases I couldn't get to any water, I'd chuck my Sim in the sea for a swim so they got clean every day.
