Only people with a showerhead in their bathtub can have a shather. A shather occurs when a person starts off having a shower, then decides to sit down, plug the tub, resulting in a bath. After they've had enough of the bath, they stand up, drain the tub, and shower off before getting out. These are ultimately relaxing.
"I had a shather the other night when I got too tired to stand up in the shower. It was great."
