Low Water Use Shower Faucet

I was in Tokyo about 4 years ago and saw the coolest shower faucet. You set the actual temperature (in C) with a knob on the left, then hit the lever on the right to make the water go. The water runs for 60 seconds and stops. Then you just hit the lever again for another 60 seconds. I thought this was an amazing design and haven't seen anything else like it in the US. It's so easy to hit the lever for more water, no resetting the temperature again or turning two knobs with your eyes closed. Capturing grey-water from poo-less showers is great. This is a way to reduce water usage in the first place. After some research, the closest match I can find is TOTO Part# TBV03401J. It's made for the Japanese market, but it's possible to have one delivered anywhere. Just wanted to share this in case anyone else found it useful!

Very cool Geoffrey;
That would work great with any normal hot water tank system.
It would not work at all, with an on-demand water heater.
With a limited water supply and a conventional hot water tank, this could be a real addition to a home.

I have been using this one

for about 6 years now. 1.5 gallons per minute on full but the switch on the handle also works to make the flow completely adjustable, zero to 1.5 gpm. They make several varieties.


It doesn't have the timer like the OP mentioned but it only required a couple showers for me to be able to find the switch with my eyes closed. Also made in the USA if that matters to you.
Not affiliated just a very satisfied customer.

Does the high sierra go to OFF?  Most keep a dribble going.

When the faucet is on mine drips a bit, maybe a drop every 3 seconds or so. I see that as a feature not a problem, its a reminder to turn off the faucet.

I have been using an all-brass low-flow showerhead since the 1980's.
It has a shutoff button but as I am using an on-demand water heater it is not a good idea to use it.
It can be easily disassembled with hand tools and cleaned of any debris.
Here is what appears to be the modern version of mine.

I like that one, the shutoff button is a great feature. Much cheaper and easier to install than the one I found.

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.
