Installation Precautions: 1. Additional sealant must be used around the Italian shower barrier (not included in the packaging). 2. For better adhesion, the adhesive can be heated with a hair dryer. 3. At the corners, we recommend cutting it at 45 degrees, then joining the two parts to make sure it's sturdy. Height 30mm/1.18inch: The height of the bathroom shower barrier is 30mm. Please clarify your needs before purchasing. Wide range of uses: 1. The kitchen counter sealing strip can be used for the edge of the counter (kitchen sink, basin, window sill, bathtub edge). 2. Can be used on the floor (bathroom floor, shower tray, around the toilet or washing machine, balcony floor). 3. Can be used as a threshold (bedroom door, bathroom door). 4. Can be used to block gaps of 0-20mm (between countertops (bathtubs, floors) and walls). High quality silicone material: The shower waterproof strip is made of food grade organic silicone, which is corrosion resistant, high temperature resistant, wear resistant and has no peculiar smell. It is flexible and can be cut at will, and its smooth surface makes it very easy to clean.
