All-in-one GTDsupply 36 Inch Linear Shower Drain Kit
The GTDsupply KL1V60E90 kit provides a complete, low-profile linear drain solution for bonded waterproofing systems. The channel body, a linear grate assembly, and essential accessories (waterproof corners, pipe seal, valve seal) are designed to work with Schluter’s KERDI linear shower tray and KERDI 200 membrane. It is suitable for walls or intermediate locations and supports showers with a single slope. The bundled components streamline installation and reduce compatibility concerns for remodels or new builds.
Key features include a tileable design, exclusive GTDsupply offering, and compatibility with popular waterproofing membranes. The kit helps in achieving a clean, minimal junction between tile and drain while maintaining consistent slope for efficient water removal. Ideal for bathrooms seeking a modern, seamless look with reliable drainage performance.
GTDsupply KL1V60E120 48-Inch Linear Drain Kit
This 48-inch kit mirrors the 36-inch version, offering extended coverage for larger showers. With a center outlet channel and a tileable grate design, it supports bonded waterproofing assemblies (KERDI systems) for reliable performance. The expanded length makes it suitable for expansive shower enclosures, reducing the need for multiple drains and delivering a uniform slope across the floor.
The included accessories ensure a watertight install, while the channel body remains low-profile to preserve floor height. This option is particularly appealing for custom builds or renovations where a single, uninterrupted drain line is preferred. Its compatibility with Schluter membranes helps simplify installation and long-term maintenance.
GTDsupply KL1DRE50 20-Inch Center Outlet Drain Kit
Designed for more compact shower footprints, this 20-inch center outlet channel kit delivers a tileable drain solution with all essential components. It is compatible with Bonded Waterproofing assemblies and works well in showers built around smaller enclosures or when a secondary drain location is not feasible. The included corners and seals help maintain a dry, clean edge around the pan, supporting a professional finish in tight spaces.
Despite its smaller size, it preserves the same quality construction and membrane compatibility as larger kits. The result is a cohesive drainage system that aligns with standard tile patterns and maintains an even slope toward the drain for efficient runoff.
GURU USA W-S Heavy Duty Shower Tray, 36×60
The GURU heavy-duty shower tray offers a robust pre-sloped pan with a four-slope configuration for a center drain. Its 36″ x 60″ footprint provides substantial coverage for larger showers, and the tray is designed to handle significant tile loads without compromising integrity. The system supports a wide range of tile sizes and includes a center drain placement that suits modern bathroom aesthetics.
Durability is a hallmark here, with a high-weight tolerance and a focus on long-term performance. The tray’s construction aims to minimize movement and cracking, contributing to a consistent, accessible slope from edge to drain. This makes it a strong choice where durability and even drainage are priorities.
Profilitec STL-TRAY132/112 Pre-Sloped Tray
The Profilitec STL-TRAY132/112 combines pre-fabricated dimensions with fiber-reinforced concrete to boost durability and grip for gluing. Its 52″ x 44″ footprint supports larger showers, and pre-cut indications help align the drain hole with the channel width. This tray is designed to fit seamlessly with linear drains and bonded waterproofing membranes, offering precise manufacturing tolerances for easier installation and a clean finished look.
The tray’s conservative height and reinforced composition reduce the risk of flexing over time, ensuring a stable base for tile installations. For remodels or new builds seeking a robust, dependable pre-sloped tray, Profilitec provides a balanced option with clear alignment guidelines.
Buying Guide: Key Purchase Considerations And Comparisons
Drain location and slope: Center-drain configurations are common for a clean look, but ensure the slope matches your tile thickness and desired water flow. A four-slope design can improve headroom for larger pans and reduce sloping inconsistencies.
Compatibility: Confirm membrane and tray compatibility (for example, KERDI or Schluter systems) to minimize the risk of leaks. Look for kits that include or specify required seals, corners, and membranes.
Size and footprint: Choose a pan that fits the shower dimensions. Larger showers benefit from longer kits (48 inches) to reduce the number of joints and potential leak points. Smaller showers may prefer 20-inch or 36-inch kits for a precise fit.
Material and durability: Fiber-reinforced concrete trays and heavy-duty plastics offer varying levels of rigidity and weight tolerance. Consider whether you need reinforcement for tile thickness, and evaluate load-bearing needs if the shower sees heavy use.
Installation complexity: All-in-one kits simplify installation by bundling components, while some trays require additional accessories or membranes. A clear installation guide and included accessories can save time and reduce mistakes.
Maintenance and longevity: Look for corrosion-resistant drains (304 stainless steel grate is common) and smooth, non-porous surfaces to ease cleaning and minimize mold or mildew buildup.
Budget and availability: Compare total kit contents, warranty coverage, and lead times. Some brands offer extended warranties on their pre-sloped trays or drainage components for peace of mind during bathroom renovations.
