Most of my Sims like to do laundry so they get what they want when they can afford it, starting with a washtub and clothesline that they have to upgrade. When they want a washer or dryer I'll get them a set. My Sims always want to upgrade one or the other so they start with a lint trap for the dryer to prevent fires and a laundry additive tray for the washer so they can use flowers from their gardens. They eventually complete all of the upgrades as their Handiness skill increases.
I also like many of the CAS and Build/Buy items.
