I’m in the 20 minute range.
Besides enjoying a moment just enjoying the spray, I also shave and use a water pick in the shower. So, after I wash and rinse the body, I still need to wash my face, get the mirror set up (it’s got this thing where you fill a reservoir behind the mirror with water - it assists with keeping it fog free - and then put it on its stand), lather, wait for the lather to “work”, then shave, rinse the face, and then do two rounds of the handheld water pick across my teeth, which require me to fill it with water each time (during the second round, I also add a shot of mouthwash, so I have to pour that, also).
My lower back is often chronically hurting, so I usually end with some stiff legged stretching, too, which loosens me up for the day. It’s nice to do under the shower.
