Another option is to turn the water off in between steps if you don't already. So turn it off when you lather up, wash your hair, etc and only use water to rinse off after each step. It helps reduce how much you use by only having the water on for a short time overall. With a lot of showerhead attachments you can turn the water off right there so you don't have to fiddle with the temperature controls every time.

I made a shitty prototype with irrigation mister nozzle heads from alibaba or somewhere similar. I used 3 mm tubing and made some connectors from 3d print.

What I learned:

• It's a fun project
• 3D prints of connectors and tube adapters will be leaky if you are not a pro and knows what type of plastic to use. (I'm not experienced enough.) I would recommend finding proper standardised tube adapters and purchase them instead.
• You save some water, however the temperature feels much colder, and therefore your guests might not like it if your water is not hot enough.
• I enjoyed the gentle feeling of it, however it is very different from a regular shower head, where it feels like your skin is power washed clean. I used my hands more for cleaning my water misted skin. I had a feeling I got just as clean.
• I vaguely remember something with some mistborne disease which there could be a higher risk of, using this kind of system, but I don't remember.

I experimented with 1-5 nozzle heads, and the more you add the more it feels like a regular shower head, with the intensity the water hits the skin, aaand the more water you use... 3 was a minimum to me.

I did not use it long enough to experience it clogging. I stopped using it because my fittings and tube adapters got too leaky to provide a proper pressure, and I didn't have the patience to fix it. This post has made me want to get a go at it again :P

I was also inspired by that article

My wife and I built a travel trailer. We needed to judge our water usage to decide capacity.

My wife has long hair, all the way to the top of her butt. Without rushing it takes her 10gal (~40L) of water to have a shower where she washes her hair. At the other extreme, either of us can take a basic shower where we turn the water off until needed, a "navy shower", with 2gal (~8L).

In the US all shower heads are limited to a maximum of 1.75 gal/min (~7L). It'd take about a half hour to use 200L+.

The first thing you could do is to heavily shorten the time the water is running. One or two minutes split between start and finish is sufficient. If even more severe limitations are wanted then install a bidet or kitchen faucet sprayer instead of a shower head.

Much is pointless, without meaningful effect. Go after the corporations polluting, using, and often stealing the vast majority of our water. And, move out of Phoenix and Las Vegas.

I thought about it, but apparently it needs higher water temperatures than what my solar-termal water heater and air-to-water heatpump usually produces, so I scrapped the idea again.
