The shampoo bottle keeps sliding off the rim of the tub. Before you buy the caddy with the nicest finish, look at the surface or fixture that will have to hold it when all your bottles are full.
Adhesive for a compatible wall
Check the product instructions for your exact surface and whether the mounting area is inside the shower. Make sure the adhesive can sit flat without crossing a grout line. Count the weight of full bottles against the stated limit. The 3M bath guide describes different waiting steps inside and outside the shower, so follow the directions for the exact model before loading it.
Over-door for a shower door with room to close
Look at the top edge of the door and the gap above it. A hook needs space to sit without fouling the frame, and the shelves should clear your body when you step in. Simplehuman’s BT1101 has an adjustable over-door hanger and movable shelves. Compare its diagram against your door and check whether your tall bottles fit.
Tension pole for an unobstructed corner
Measure from the actual floor or tub ledge to the ceiling at the point where the pole will stand. Check the model’s supported height range and whether both ends can sit securely. Leave enough room to use the shower controls and move comfortably.
A flat, compatible wall points to adhesive. A door that still closes points to a hanger. A clear corner with compatible contact surfaces points to a tension pole.
