EXF Square Shower Drain 6 in Matte Black - High Flow, Adjustable

Our review of the EXF Square Shower Drain 6 in Matte Black finds it best for homeowners and installers who need a durable, high-flow floor drain with a discreet, embedded look. The single biggest reason to buy is its combination of 304 stainless steel construction and a 2 in central outlet that handles high flow to reduce ponding; this product feels built for tiled and hot-mopped shower pans where reliable drainage and corrosion resistance matter. It is a practical choice when compatibility with common US drain pipes and easy maintenance are priorities.

Key Features

• 6 in square drain size: The 6 in x 6 in grate provides a wide opening that helps water evacuate faster and reduces standing water.
• 304 stainless steel construction: The matte black finish over US ASTM standard 304 material resists corrosion, scratches and rust for long life.
• 2 in central outlet: The standard 2 in outlet and compatibility with 2 and 3 ABS, PVC or cast iron pipes make installation straightforward for most US plumbing setups.
• Adjustable height: A threaded adapter allows up to 1 in of height adjustment so the drain can be set to match tile or pan thickness without custom parts.
• Removable grid and hair strainer: The lifting key removes the cover and debris strainer easily so cleaning is simple and access to the trap is quick.
• ABS drain base and rubber collar: The ABS base and rubber collar secure the drain to the flange and reduce the risk of leaks when installed correctly.

Who It's For

This drain is aimed at homeowners renovating a shower, tile contractors, and DIYers who want a durable, attractive floor drain that reduces ponding and is straightforward to plumb into standard US drain lines. The matte black finish and embedded style suit modern bathroom aesthetics where the drain should be subtle rather than decorative.

Those who need a drain specifically for a Schluter Kerdi shower system should look elsewhere, as this model is not compatible. Also, buyers wanting a round or decorative statement grate rather than a minimalist square grid may prefer a different style.

Pros & Cons

Pros

• Solid build with 304 stainless steel top for corrosion resistance and a premium feel.
• High flow 2 in outlet and 6 in grate reduce ponding in most shower installations.
• Adjustable height and included rubber collar make alignment and sealing easier on tiled pans.
• Removable grid and hair strainer simplify maintenance and debris removal.

Cons

• Not compatible with Schluter Kerdi shower kit, so it is not universal for all waterproofing systems.
• The matte black finish may show wear over very long periods in harsh conditions, though material resists rust.

Our Verdict

The EXF Square Shower Drain 6 in Matte Black is a practical, value-minded choice for tiled and hot-mopped shower pans where a robust, high-flow drain is required.
