Bathtub Remote   (+2)  [vote for, against]
No movement necessary

Bathtubs, the ones I'm used to, all have the controls at the same end as your feet. Can't put your head at the correct end without hitting the spout or controls. The usual method of adding hot water is to attempt to twist the knob with your foot, this sometimes works, but I usually end up not being able to turn the knob off --- drip, drip, drip. A remote is needed, with simple settings to add hot or cold water, and perhaps activate the drain valve to dump some water. Either a wireless device, waterproof of course, or simply an alternate set of knobs closer to the other end of the tub.

Until the final creation of the Bathtub Reheater this simple device can turn the tab into the fully relaxing experience it should be. Remotes for hot tubs and spas are plentiful, but have yet to see one for the stanard tub.

Tragically misguided attempt to control water level by leading a horse to water while sitting in it http://home.att.net...S/LeRoy_Bathtub.jpg

is there some sort of law against sitting at the tap end of the bath? rbl has obviously never taken the share a bath - save water propaganda to heart.

sp. red pen - standard.

You've never heard of the Stanard (tm) Tub?

Put the taps at the side, halfway between either end, so two can relax without having taps in the back of the head and either of you can reach the taps with little or no stretching.

This is a problem I have noted when adding more hot water, how do you prevent an over full bath?; Set up the remote controlled plug so it's a heat filter. It only lets out water below a certain temperature. For energy savings this water could be routed to an extra tank in your boiler for reheating and returned to your bath.

<bangs on door> [zircon] what *are* you doing in there, its been an hour at least.

I think Zircon is onto something.

The bath should maintain a constant temperature - a thermostat will ensure that hot water is added as appropriate, and overflow will be prevented by a corresponding automatic plug letting water out when necessary.

You wouldn't even need a remote control then.

You just recirculate the water though a low wattage heater/filter system; suck cool water out through one nozzle, and re-inject it through another. Large diameter nozzles to give a high mass flow rate with minimal turbulence. Saves energy, saves water.

If the filter is efficient then the bath can be shared either concurrently or sequentially. <Thinks> Must make filter self-regenerating/backwashing/auto-flushing, do not want job of cleaning filter once a month, Eeeeeewwww...... </thinks>

NB I have showers, not baths, much more hygenic.

In a fairly roundabout way I think we've just arrived at the concept by which heated swimming pools work.

I think the idea of remote control taps is a good'un too though, if just for the servo controlled taps wirring away on their own. I love remote control housing. You could link this in to your home control system. A bit like what rods was saying.

Zircon's idea was, in fact, the Design Tech project of one of my GCSE contemporaries. I don't think he ever got it to work, though.

I had a bathtub in Japan with a very remote control. . . in the kitchen. You told it what temperature you wanted the water at, and it filled it up, and stopped when it reached the optimal depth. Very cool, or hot, depending on your taste. . .

Forget the remote, how about voice activated, or no... Clapping activated. One clap hot, two claps cold - or was it the other way around? Yeeooow!
