    What is a double bypass shower door?

    A double bypass door features two sliding glass panels that can both move independently, allowing entry from either side of the shower.

    How thick is the glass on Portofino double sliding shower doors?

    The Portofino series uses 3/8" (10mm) thick SGCC-certified tempered glass for maximum safety, durability, and a premium, heavy-duty feel.

    Can I install these doors on a bathtub?

    Yes, we offer double sliding frameless bathtub doors specifically designed at a 62-inch height to fit standard tub configurations perfectly.

    Are these shower doors easy to clean?

    Absolutely. Our glass features an easy-cleaning coating and Enduro Shield technology that repels water and soap scum, significantly reducing maintenance time.

    What finishes are available for the hardware?

    You can choose from polished Chrome, Brushed Nickel, and Matte Black (or Oil Rubbed Bronze) to match your existing bathroom fixtures.

    Do these doors leak water?

    No, our frameless double bypass sliding shower doors come with high-quality clear vinyl seals and water deflectors to keep moisture inside the enclosure.

    Is the installation difficult?

    While the package includes a comprehensive manual, we recommend a two-person installation due to the weight of the 3/8" professional-grade tempered glass.

    Can the width of the doors be adjusted?

    Yes, the top support rail can be trimmed to fit your specific wall-to-wall opening, offering up to 4 inches of horizontal adjustability.

    Frameless double sliding shower doors eliminate bulky metal frames, creating a cleaner look that makes small bathrooms appear much larger and brighter.

    Is the glass safe if it breaks?

    Our tempered glass is designed to crumble into small, dull-edged granules rather than sharp shards, ensuring the highest safety standards for your home.
