I've noticed over the years that homes and apartment built prior to the 70's often have a hot and cold shutoff in the wall somewhere, protruding like shower valves, usually near the toilet - for all water to the bathroom- tub/shower, sink. toilet. Since then these valves have disappeared as individual shutoffs would be incorporated under the sink and toilet - but not for a tub or shower. I figure changing valve washers was a pretty common thing that needed to be done regularly due to rubber washers...
But nowadays with washer-less ceramic cartridges, and the longevity of newer washer material (neoprene?) are under-sink shutoffs even really necessary? Or is there a code that requires a shutoff for a sink, but not a tub or shower, in bathrooms and kitchens?

If it's not code to have valves at every fixture, it should be.
I even install them on the tub and or shower.
Momma will not be happy with the water shut off to the whole house while your trying to do a simple repair.

Today you can get rough in shower faucets with hot/cold screw shut offs, accessible when you remove the cover plate.
Shut off valves are a must.
Shut off valves that function are even better.
I replace shut off valves and angle stops that are hard to turn on a regular basis.

In one and two family homes the IPC does not apply, rather, the IRC is applicable. Specifically, Section 2903. Each fixture (other than a bathtub or shower) is required to have accessible shut off valves either at the fixture or at the manifold.
