I would like to turn on mood lighting automatically when I'm taking a shower, what's the best way to detect that?

I've considered humidity sensors, but that will take a while to kick in and not immediately when the shower starts.
I've also considered a water leak sensor but those are not meant to be trigger every day for a long time like 10-15 minutes. That would kill the battery, right?
Smart valves can kind of work, but it feels like overkill because I don't care about the valve functionality.

I would prefer the solution to be battery powered (don't want to be messing with too many cables around a shower), but I can't seem to find one.

I would just go with special button, the most straightforward simple solution you have direct control over. Also sometimes you might need to use the shower without mood lights and then system based on humidity or water flow will just be annoyance.

If you use some tools when showering, like brush or spung, you can make a contact sensor into the hook/holder (more work, probably need a custom 3D print), but should also work and you don't need to press anything
