It is very natural for people to sing in the shower; however, it can be seen as slightly inconsiderate if you’re belting out off-key show tunes in the middle of the night. If you plan on singing in the shower, please be courteous to those around you by singing late in the morning or early in the evening (basically follow quiet hours). Also, if you’re a great singer, I don’t see the problem with you singing in the shower, but maybe you should share your talents with the world instead of the showerhead. If you’re a poor singer, then maybe you should sing in your room or practice singing softly. Lastly, what songs are you singing? Make sure the songs you are singing are enjoyable to others, so that means no Miley Cyrus.
