I have a problem with certain family members and exceedingly long
showers. Pleading and screaming has no effect. The water bills and the
gas bills are outrageous.
I've seen some commercial products that control long showers but they
are poorly reviewed and expensive.
I was thinking of a solenoid controlled valve on the hot water line of
the shower. I'd plumb in a bypass to keep a tiny amount of hot water
going in, but cut off the bulk of the hot water with a valve like this:
<(Amazon.com product link shortened)> (rated to 80°C).
To trigger the micro-controller that controls the valve I'd use a flow
sensor such as <(Amazon.com product link shortened)> (rated to 100°C). A
dishwasher valve would also work.
So basically it would be a flow sensor and a solenoid controlled valve
in series with the hot water line, and a bypass with a manual valve.
My daughter did the same. I reduced the temperature of the hot water
tank over a few weeks time. She still stayed in the shower until the
hot water ran out but then it ran out a lot sooner.
I got used to the somewhat less than scalding hot water and still keep
the water temp at the lower setting.
Buy the way, I didn't tell my wife what I did. It is true, silence is

It's a catch-22. If you can't control them with words or other
sanctions, they'll just
find a way to get back at you for your technological solution.
Probably easier to put a humidity or temperature sensor on an air-raid
Teach them how to pleasure themselves before they get into the shower.

Timer controlled valves for showers are pretty common since they're used
for coin-operated showers at campgrounds, etc.
What's different is that I would not use a timer controlled by coins or
tokens, but one that starts when the hot water begins to flow and that
cuts the hot water supply after a certain number of minutes.
Changing showers to coin-operated plus upping everybody's allowance by
an amount equal to the expected normal shower time per week would be the
solution I'd expect to work.
Let her feed quarters into the thing to her heart's content.... but
after a certain point, they're going to be *her* quarters.
That reminds me of an apartment I lived in. Instead of expensive coin
operated washers and dryers, the owners installed a coin operated power
controller, which was really nothing more than a timer. The cord for the
standard washer and dryer each went into a coin box. The sign said $0.75
per load. As soon as the third quarter was inserted, the power came on and
stay on for a set number of minutes.
I learned early on that if you added a quarter during the cycle it would
extend the time. If you were ready to switch loads as soon as the first one
was done, you had just enough power to do 2 loads for $1.00. If you were a
little late, it might cost you $1.25.
I've seen that too but it makes little sense. The reason that the
commercial machines are more expensive is not the coin slide it's that
they build them with much more rugged components in order to have them
stand up to continuous use.
Each building in the complex only had 4 apartments, 2 one bedroom and 2
slightly larger 2 bedrooms, but the 2nd bedroom was pretty small. In most
cases there were never more than 8 people per building and even that was a
lot. It was mostly singles and couples, not too many kids.
The rugged commercial machines would probably be overkill but with enough
$1.50 wash & dry loads, they probably made enough to maintain the standard
machines. That' sustainable my guess, I never did the math. Of course, if
enough people used the timing trick that I did, that would throw their
numbers way off.
Whoops..emailed you by mistake. Sorry.
Anyway, I wasn't running the complex, just washing my clothes. ;-)
If you want to call them and find out why, 30 years ago, they were using
residential washers instead of commercial machines, I can send you their
current number. Let me know. ;-)

I had one daughter who hogged the shower and I solved this by going
down to the basement and slowly closed the hot water valve to the
bathroom. When the screaming stopped as the cold water hit, I
opened the valve a bit. She soon learned to play fair and allow others thei
r turn in the bathroom.
