The same hot and cold connections of bath faucets can be achieved in a slightly unusual manner. Bore a hole at the tub rim, or wherever you happen to want the connections to be, and install a threaded male fitting. A neater way to do this is to drill the hole and countersink the threads on a threaded insert. Then, for completeness, install the faucet on the bathtub. Lastly, screw the male fitting into the fitting on the faucet. The screw threads into the tub faucet threads, holding everything firmly in place.
For additional convenience, install a second faucet, smaller than the main one, off to the side of the main faucet, which can be used to get a cold drink or dish of ice at that moment. The left-hand faucet is typically an adjustable sprayhead, while the right-hand one is a finger-controlled spiral spout faucet just like a sink.
Most hot water fixtures are installed with a stop valve that is opened by the flush lever and allows water to flow back into the hot water tank when the toilet is flushed. This is to prevent a running toilet and the dirty water in it from overloading the hot water supply to the appliances. Most families haven't mentioned it, but to make sure the water in your hot water tanks stays hot, you also need to flush the tank before standing in the shower. This is to prevent cold water from entering the tank when the hot water supply shuts off, which would cool the water in the tank and damage it. You can postpone a flush by pressing the flush knob or lever while using the hot water, but make sure you press for a longer moment than the one-second push-pull cycle the device usually provides. When you finish your shower, shut off the hot water and flush the tank with cold water from the kitchen tap. Turn the hot water back on and enjoy your very hot -- and very cold -- shower, with just the right temperature of water. d2c66b5586
