I change ours out about every 4 days or so. The hand towels get changed more frequently. If the heat or air is on, they dry quickly and don't need to be changed as often, but if the windows are open, then it seems like they just never get dry. Scott uses one and I use two, as does Helen. Scott's children, when they are here, seem to be towel hogs and I always have tons to wash! LOL!! Plus, with summer time here, there are lots of beach towels to be washed as all 3 children spend lots of time at the pool. Thank goodness I have two sets of washers and dryers!
