When selecting the number of faucets, the following aspects should be considered:
1. Usage requirements: If there is only one bathroom or a kitchen water point at home, then a faucet may be enough. But if there are two bathrooms or two kitchen water points at home, then two or more faucets may be needed to meet the demand.
2. Installation space: If there is enough installation space at home, you can choose multiple faucets, which can facilitate the use in different areas. But if there is not enough installation space, it needs to be adjusted according to the actual situation.
3. Usage habits: Everyone's usage habits and operation methods are different. You can choose an appropriate number of faucets according to your personal needs and habits.
In a word, the choice of one faucet or two faucets is determined by actual needs and usage habits, and there is no scientific feng shui basis to prove its right or wrong.
