Hanging shower product dispensing bottles are pretty cool. They are generally out of the way and are refillable so they are handy and well suited for the bathroom environment. Few other products are as well designed for use in the house clean room. Clocks seem to be uniquely vulnerable to the ravages of humidity and the pH of bath products. There are many reasons to have an accurate timer in the bath, however: Timing product applications, topical medications, softening hair for shaving, even ultimatums like "you've got exactly one minute more in there, mister, before like it or not I'm coming in to take a squat".
I propose that a hanging dispenser bottle of the type seen in the first link below be designed with a water resistant and twist-able setting built for timing 1 -5 minute intervals. It would work like a twist-able shower soap dispenser with a built-in 1 - 5 minute timer-- dpsyplc, Jun 01 2004 8 Ounces, White PVC Hanging Container http://www.bottlesandjars.net/c26.html-- a common configuration.

[lostdog, Oct 04 2004, last modified Oct 05 2004] I bought an ordinary egg timer, wind-up type for my son who will take a 30 min shower and uses every drop of Hot water. He has had it for a year and not used it once. but I was looking for a water proof one like you describe. so +-- dentworth, Jun 01 2004 [dent] you need to build a valve with a simple mechanical timer into the hot water line. As the knob on the timer turns it slowly turns off the hot water. Of course it has to be put in somewhere out of reach of the shower.-- kbecker, Jun 01 2004 Speaking of 'turning the water', why do showers always spray from above when I'm so dirty down under? Is the water pressure in the developed world so poor that sprays can't arc up at about 45 degree angles?-- dpsyplc, Jun 02 2004 [dpsyplc] I completely agree with you, but the better solution would be a shower head on a hose. They are common in Europe, but hard to get in the US.-- kbecker, Jun 02 2004 what about shaping the bottle of conditioner etc.in such a way the after dispensing it could be turned upside down with a liquid "hour glass" formed into it calibrated to correspond with the duration of time prescribed?
in lieu of that (+).-- xclamp, Jun 02 2004 "valve with a simple mech. timer" thanks [kbecker] will look into that.-- dentworth, Jun 02 2004 Here in Australia, we're in the throes of drought, and water use reduction is the name of the game. Our local water treatment and supply company is selling a shower timer for about A$7, along with their ad campaign promoting the joys/benefits/socially responsible good feelings of a FOUR MINUTE SHOWER. Yes, my showers are short. No, I am not as clean or relaxed as I once was.-- araminty, Jun 02 2004 You're another candidate for Pedant's Anonymous, Zanzibar.-- WordUp, Jun 20 2004 random, halfbakery
