Better off grid options please! (Possibly with farming pack)

I would definitely like off-the-grid living to be more sensible/realistic. Some of the options they omitted from off-the-grid seem strange. For example, my sim built a wooden bath via the carpentry bench but his family has not been able to use it while I'm keeping them off-the-grid. The only thing I could do with it is bathe toddlers (thankfully).
