Why sing in the shower?

There are people who enjoy singing in the shower mainly because it listens to itself very well.
This is because the shower works as a rudimentary recording studio: increasing the volume of sound, enhances the low and produces echo.
The tiles of the room reflect the sound over and over again in all directions, which boosts the intensity of the sound and provides a voice "potenle more."

The echo is achieved by the multitude of reflected waves that reach the ear at different times, which makes the sound of the melody is more full and rich.
Finally, the bathroom functions as a resonance chamber that amplifies the low frequencies.
