To add to this. The sensory experience of showers is a lot.

1. being comfortable in your warm clothes
2. having to take them off to get cold
3. having to get wet and warm
4. having to dry yourself with a rough (ish) towel
5. Getting cold again
6. Damp air makes it harder to breathe
7. Putting on different clothes which potentially feels different from the used ones
8. Getting out of the bathroom to non-humid air
9. Coldness of the remaining water (hair etc) evaporating

I also have sound sensitivities, so the sound of water hitting the floor is also disturbing.
