The best shower mirror nowdays is the mirror with demsiter pad in bathroom.

The mirror demister automatically ensures mirrors are steam free after bathing or showering. The Mirror demister product also leaves mirrors demisted, enabling you to shave or apply makeup without having to wait.

This product uses up to 50% less power consumption than the leading alternative and is easy to install. It simply adheres to the back of your mirror, and can be wired through the lighting circuit. This system is regularly used in hotels and new build projects. There are eight different sizes to ensure a perfect fit for each individual mirror. The various mirror demister pads can be mixed and matched for use on very large or unusually shaped mirrors.

The NRG mirror demister has a self-adhesive backing enabling it to be easily attached to the  of a mirror. The mirror can then be affixed to the wall using mirror adhesive. The adhesive can also be used on the back of the mirror demister pad to further secure the mirror to the wall, as long as the adhesive is solvent free. If being used with a safety-backed mirror the backing should be earthed, as should all metal parts surrounding the mirror.
