Tile Grip
Smaller 3.7" suction pads for showers the larger cups can't fit — 4" tile especially, where a 4.7" pad would cross a grout line and lose its seal. Extends, and works on bigger tile and smooth panels too.
Each pad has to seal inside one smooth tile face, clear of the grout. Drag the back of a fingernail across it: it should glide silently like glass. Any faint rasp or grain breaks the seal, and water that soaks in means the tile is porous. Passed? You're good to go — and you can return it within 30 days in its original packaging if not (shipping isn't refunded). Full surface test
Position each suction cup inside a single smooth tile face, clear of the grout line. Push both levers down to secure. Lift the levers to remove or reposition — anytime, with no residue and no damage to tile.
Bathrooms with small 4" tile, where a larger pad would cross a grout line — plus anyone who wants the flexibility to place the cups precisely.
