Stainless Steel Corner Shelf with Acrylic Tray has a strong and reliable suction power and is guaranteed to stay sucked on for ages. This is ideal on tiles, glass, or mirrors.
The suction on the Naleon Super Suction brand is like no other and comfortably holds up to 8 kg of weight. It does not need screwing or nailing required. It has exclusive surface warning indicator.
This stainless steel corner shelf can be mounted to to ceramic tiles but not porcelain, marble or textured tiles as they are porous and will allow air to enter behind the suction cap, which is where the mounting discs would be used.
