Having a tumble dryer is a nice thing to have if you do laundry at home because the tumble dryer will dry clothes faster so they'll be ready to wear sooner.
But you can get by without a tumble dryer and just use a laundry drying rack or even a clothesline either indoors or outdoors.
When laundry is dried outside on a clothesline the fresh air is actually good for helping get the clothes fresher than in a dryer.
The clothesline is a natural way of drying clothes and also saves you money instead of using a tumble dryer.
Still I love to use my tumble dryer in the winter for drying clothes but could dry them inside on a drying rack but it takes longer on the drying rack and I prefer the convenience of the tumble dryer instead.
Many people did years ago dry laundry outside on a clothesline or drying rack so it's possible to get by without the tumble dryer but they're nice.
