Services
Custom Frameless Showers
Custom frameless shower enclosures use 3/8" to 1/2" tempered safety glass for durability. These designs eliminate heavy metal framing, offering a sleek, modern aesthetic. Ideal for residential and commercial spaces, they combine structural integrity with easy maintenance.
Mirrored Wardrobe Doors
Mirrored wardrobe doors feature premium aluminum extrusions and smooth-gliding systems. Available in multiple finishes and configurations, they enhance closet aesthetics while providing functional, space-saving solutions for modern interiors.
Diamond Seal System
Diamond Seal System applies a hydrophobic nano-coating to glass, preventing water corrosion and stains. This lifetime-warranted treatment ensures easy cleaning and maintains optical clarity, ideal for shower enclosures and high-moisture areas.
Custom Mirrors
Custom mirrors are tailored to fit any space, from decorative accents to full-wall installations. Available in various shapes and sizes, they enhance lighting and create the illusion of expanded space in residential and commercial settings.
Sliding Enclosures
Semi-frameless bypass sliding enclosures use 1/4" or 5/16" glass with durable hardware. Designed for ease of use, they are perfect for tub and shower applications, offering a modern look without compromising functionality.
