Upgrade your shower with Trimslate double threshold shower bases. Featuring two add-on thresholds that accommodate shower doors effortlessly. Threshold adjusts the maximum depth and width up to 2.5-in without any trimming of base. Crafted from solid sheet-molded compound material with sturdy structural ribs, it ensures durability and stability. Field trimmable for customization, it installs easily atop thinset mortar. The lightly textured slate floor is slip-resistant and easy to clean.

• DOUBLE THRESHOLD: includes (2) 80-in long add-on trimmable thresholds with a 45-degree mitered edge to be cut in the field to size; thresholds have a 4-in wide flat surface to accommodate shower doors
• TRIMMABLE: trim up to 4-in in width away from side opposite drain or up to 2-in in depth away from drain without any loss of integrity
• MATERIAL: sheet molding compound (SMC) material is made from a composite material composed of resin, fiberglass, and stone filler to create a lightweight and durable material that is stronger than acrylic
• DOUBLE THRESHOLD: the unique adjustable depth thresholds are designed so the maximum depth and width can be adjusted by up to 2-1/2-in without any trimming of the base; 4-in threshold depth accommodates any shower door
• REVERSIBLE DRAIN: end drain location with SMC color-matched drain cover that conceals a conventional 2-in shower drain, creating a pleasing uniform and minimalist design; drain not included
• WATERPROOF: includes three 1-in high aluminum tiling flanges which can be attached to the shower base using epoxy or 100% silicone to ensure no water will sneak in the cracks between your shower base and walls
• INSTALLATION: install atop a thinset mortar mix; once the base is level and drain is installed, install your wall substrate material 1/4-in above the aluminum flanges and install the shower walls on top of the base with added silicone
• STRENGTH AND DURABILITY: solid material all the way throughout the base, which is beneficial for protection against scratches, nicks and gouges; has 4 times the impact resistance and 2.5 times the temperature resistance as other bases
• SUPPORTIVE FOUNDATION: the back side of the base employs structural ribbing to easily achieve a perfectly level base while maintaining superb strength
• SAFETY: lightly textured slate floor is slip-resistant and maintains an easy-to-clean surface
• WARRANTY: covered by a hassle-free 10-year limited residential or 3-year commercial warranty
