Design Configurations

We specialize in precise shower glass fabrication. From tight corners to unique layouts, we'll deliver glass that fits perfectly every time.

    Door: A single door is a great option for openings less than 36″ wide.
    Door and Panel: Openings larger than 36″ typically require an adjacent panel on one or both sides of the door.
    Door and Notched Panel: Showers with a seat or a knee wall may require a notched side panel.
    Neo-Angle: These enclosures are designed with panels that do not meet at a 90-degree angle, making them ideal for corner spaces.
