Personally, I LOVE my showers.
In, washed, shampooed, pits shaved, face washed, and out in 10 minutes or less. Back to my life.
I do realize that shower-haters have some valid points. I abhor head-movers-- but I've learned to deal with moving it back. Mark the spot on the wall where the spray is supposed to hit with a dot from a Sharpie. Works wonders-- I swear, someone at my in-laws delighted in moving the shower head so it would spray water on the floor just so they could yell at me for getting water on the floor. This makes it fast and easy to put the shower head back in the right place.
They're really NOT kidding about the dishwasher/washing machine/toilet flushing while in the shower business. It was very difficult for my mother (a 45-minute shower fan) to get me to understand and remember this. Saint Alan cured it easily: ONCE, while I was in the shower, he flushed the toilet-- I never scalded anyone again. ONCE, he ran a load of "hot" laundry-- I never froze anyone again. Please be advised that he made sure to explain what had happened, and that he'd done it deliberately to illustrate a point, and to be kind in the explanation, not loud or accusatory or angry, just sensible. Try it on YOUR family.
Spray hurts-- sometimes, I can't tolerate it either. That's generally when I take a sponge bath, or use the kid's leftover bathwater and a pitcher.
The important things here are soap, water, shampoo, and a washcloth. It matters that they are applied frequently. The method of application is far less relevant (unless you happen to be an environmentalist, or just strapped for dihydrous monoxide-- in which case the sponge bath is definitely preferred).
