We have, roughly, a bazillion.
4 nice super big towels for my husband and I to use for the bath. 4 back up decent towels for adult baths, formerly the good bath towels but downgraded due to smallish size. 8 older but usable towels in case of dire bath towel need, with bleach spots, holes, etc. 6 hooded/cutesy towels given as gifts to our 2 children. 8 frayed and thread bare towels used for the dog, wrapping yogurt in the crockpot, etc.
These towels span from a year old to 20+ years old. I can't be the only one who has a regular need for lots of bath towels...kitchen floods, washing machine issues, child who decides to empty bath tub on to the floor, etc...when not attending to floods, we wash our towels every week to every other week, I usually use them to fill out loads.
