Hang on. When people say they share, do they mean everyone uses the same towel on the same day? So Dad has a shower, uses towel, then Mum uses the same towel, then teenager, then toddler... You all use the same one? Don't they get wet? And very dirty?
This will gross you out, but yes! We all use the same towel.
As it happens we generally have two people shower of a morning, two people shower if an evening due to individual preference. So first person gets a dry towel. Next person gets a wettish/damp towel. It then dries during the day. First evening person uses it dry, next person uses wettish/damp.
The only exception is if someone is sick, towel gets put in with wash after them or if DD has period, then she puts it in wash after use and puts fresh one on rack for next person.
They don’t get dirty as each person has just had a shower which washes all the dirt off so you are just drying off a clean body and we use cetaphil or similar as our body soap
.
To gross you out even more we try and get a week out of the one towel if we can. Why? I have enough washing as it is, don’t want one more thing than absolutely needed. The reality is no one has died, become sick or suffered in any way so we will keep on keeping on. If kids (teens and adults)want to use their own they can but by god they will then also be responsible for a load of washing. Cue crickets and reusing of the towel
