The Half-Round Shower Door Threshold is a component for shower stalls, designed to assist water drainage back into the shower area. Constructed from aluminum with a brite anodized finish, this threshold is suitable for flat or out-sloping curbs. It features a rounded low contour for foot safety and a tapered sill with a minimal exterior sightline. The threshold measures 95" in length, 13/16" in width, and 3/32" in thickness, with a height of 1/4". It is compatible with monolithic tempered glass and can be used in conjunction with a bottom sweep. Installation is performed by adhering the threshold to the curb below the shower door using mildew-resistant silicone. This threshold is specifically engineered for use in residential or commercial shower enclosures where water management is required. The aluminum construction provides a stable base for the shower door system, while the brite anodized finish offers a clean aesthetic that complements various bathroom hardware styles. The tapered sill design ensures that the threshold does not obstruct the entry or exit of the shower, maintaining a low profile. By directing water back into the shower basin, it helps maintain the surrounding floor area. The threshold is compatible with monolithic tempered glass panels and is designed to work seamlessly with standard bottom sweeps to create a functional barrier against water leakage.
