Upgrade your shower with Trimslate single threshold shower bases. Featuring a single add-on threshold that accommodates shower doors effortlessly. Threshold adjusts the maximum depth 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.
- SINGLE THRESHOLD: includes (1) 80-in long add-on trimmable threshold; threshold has a 4-in wide flat surface to accommodate shower doors
- TRIMMABLE: trim up to 4-in in width away from either side of 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
- SINGLE THRESHOLD: the unique adjustable depth threshold is designed so the maximum depth can be adjusted by up to 2-1/2-in without any trimming of the base; 4-in threshold depth accommodates any shower door
- DRAIN: center drain location with modern rectangular stainless steel 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 Transolid’s hassle-free 10-year limited residential or 3-year commercial warranty
