Remember the older style bathtub faucet with the two handles? Every time someone would flush the toilet or turn on the tap the water in the shower would run hot or cold. The reason this would happen is because of the draw of water to another appliance would cause a pressure drop at the shower.
If you were running the bath this would not really matter as most people do not get into the tub until the water is almost finished running.
Today’s newer faucets are built differently so that this problem does not happen. The newer style single lever faucets are now mandatory and have springs inside the valve that will adjust the flow according to the temperature or pressure. If you are taking a shower and someone flushes the toilet you might notice a drop in pressure coming out of the shower head but you will no longer notice a temperature change.
These newer faucets are now mandatory in all new home construction in Edmonton.
If you live in an older house and need to change out the faucet then you will need to install a cover plate that will cover the old holes. The only plate that I have seen is made by Delta and can be found at most of the hardware stores in Edmonton.
Choosing a Faucet
Regardless of your budget you will want to choose a good faucet for your tub/shower. Unlike your kitchen faucets or basin faucets you cannot easily change the faucet later on. Once the tub/shower is in place with either a tub surround or tiles you will only have access to the body to change out the stem. To change out the whole faucet you will need to get access to the other side of the wall.
If you stick with a name brand faucet you should be good, such as a Hans Grohe, Delta, or Moen faucet. I have installed some pretty cheap faucets for people that insist on going with the lowest price and a couple of these leaked within a few days of installation. Luckily, I was able to change these out before the bathrooms were being drywalled. Since these leaks were very small there could have been quite a bit of time pass before the leak would have been discovered if the drywall would have gone up. This would have caused mold and rot and is not worth the $50 or so in savings.
If you decide to install a tub/shower faucet yourself you should use copped pipe for the piping to the spout and for the shower head. It says this in the directions but a lot of people don’t read the directions and will run pex tube to the spout. If you do this then when you turn on the faucet the flow will want to run up through the shower head as the pex tube is too small to handle the flow.
Always remember that you get what you pay for…
