Some shower mirrors use a strong adhesive to attach to a shower wall. While an adhesive attachment tends to be more dependable than suction cups, it usually leaves a residue that is hard to clean.
To install with double-sided, water-resistant tape: keep the shower wall clean and dry, peel the adhesive backing like a sticker, mount to your desired location, and hold until firmly secure.
If you do not want to leave residue on your wall, choose a shower mirror that uses suction cups. Mirrorvana has upgraded its shower mirrors' suction cups for more reliable and stronger mounting.
