When we lived in Ontario, Hubby installed a simple shut-off valve between the shower head and the stem and it did the same thing as the button - just a separate piece. So if you have a shower faucet you like already, you could consider that option. It was like a lever ball valve, but a bit "pretty" as opposed to the industrial sort often seen.
