Some centers charge a towel or robe fee to offset the cost and encourage people to BYOT. I'm not a fan of that, but it does raise the question of whether it would be good to offer a cheaper towel for free or a better, plusher towel or robe for a premium. I think it depends on your float center and the image you want to convery. Many women like to have two towels: one for body and one for hair. Just like they have at home. Robes are great for both men and women and a nice touch .. kind of a requirement, IMO, considering the price and nature of the service.

The obvious answer is it depends on how many people you have floating. However, If you are smart in what towels and robes you use, you can cut down on the laundry burdon significantly. We now use waffle weave robes and smaller lighter towels and have cut our laundry burden in half.
