One of the most compatible mounting surfaces for suction cup shower mirrors is a clean, dry, and smooth ceramic tile surface. As long as the mounting surface is flat and thoroughly clean, the suction cup sticks well. Make sure to mount it on a spot without any bumps or gaps.
Mirrorvana shower mirrors use a special sticky suction technology that works extraordinarily well on most flat and smooth surfaces including ceramic tiles, glass, and fiberglass.
