[BlindHandyMan] Bathroom Shut-off valves

[Betsy Whitney]

Aloha everyone,
I've always wondered this. In every bathroom that I've had, there are 
water shut-off valves under the sink for the hot and cold water. 
There is a valve on the side of the toilet to turn off the water to 
it. But I've never seen valves for the bathtub/shower. We have to 
turn off the water to the whole house.
Anyone know why?
