Rarely have a bath but I have a shower every morning and again in the evnings many days. I find a shower in the morning wakes me up. I suppose I have a routine but haven't really thought about it
Shower in the morning to wake me up. A nice long hot bath in the evening to relax. I usually take a book in to read and have been known to take a glass of wine as well.
Shower in the morning and the evening. I treat myself to a long soak in the bath when I have time to relax and always enjoy a glass of wine or a G&T or a sometimes a drop of whisky.
I'm a shower person with occasional bath. Luckily not on water meter.
My logic for showering in the evening is to wash off the dirt of the day before getting into bed and so you aren't sleeping in dirt.
But I also like morning showers to get me set for the day so although not very environmentally friendly, like many of you I usually shower twice a day.
