My towels get changed once a week. I have two hand towels, one *face towel* and one bath towel and a couple wash cloths that I use during that week. With the cost of water in our municipality, I've made a decision to be conserving in the amount of laundry that I do. If at any time I felt that any particular towel was *gross* I would certainly wash it. I'm probably more of stickler for dish towels which probably don't get used for any length of time and I use a lot of paper towels in the kitchen.

On the other hand, when the dog gets bathed, his towels are washed after one use.
