The last time we were at OKW in DisneyWorld, we received soap, shampoo and conditioner, as well as a small (tiny) box of laundry detergent. In the kitchen, there is a (tiny) bottle of dish detergent.
We recommend, if you have a car, leaving all that stuff at home and driving to Winn Dixie to stock up on those essentials for your stay. It's far cheaper than buying extras from Disney! We also "save" the branded Disney stuff to take home for the kids to use later.
They did do a replenish mid-week if you're staying a full week (same for towels, sheets, etc.). Housekeeping comes in mid-week, although you could pay extra for daily if you choose.
