A shower radio is a battery-powered radio that is waterproofed to allow it to be used in a bathroom or other wet environment. Some versions also include a CD player and/or a clock. Shower radios generally lack headphone jacks and AC adapter ports, which could short out or electrocute the user. For the same reason, they also tend to lack external antennas.
There are varying designs; some are meant to be hung from a pipe or shower rod, while others can be stuck to the wall of the shower using a suction cup or something similar. Shower radios may be analog or digital. More recently, water-powered and wind-up radio designs have been produced to completely remove the requirement for batteries.
