Safety tap

thingiverse

My wife suffers from dementia, she enjoys taking baths. One day while still in the tub, she nearly burned herself by draining it while turning on the hot water full blast, and then froze up. She failed to shut off the faucet or escape the tub. I was plagued for days about what to do next. Researching thermostatically controlled taps didn't yield many results; replacing parts with installation added an estimated $2,000 to the total bill.
