The best black square shower drain depends on the opening size, plumbing connection, grate style, and installation kit you need. The WEBANG 6-inch drain is a strong fit for buyers prioritizing stated certifications, while the 4-inch square option suits shoppers seeking a smaller grate. EXF and Dilvii offer 6-inch alternatives with included flange components, and WEBANG’s reversible-cover model is worth considering for a tile-insert look. Confirm your drain base and tile requirements before choosing.

WEBANG 6-Inch Quadrato Shower Drain
This WEBANG model is best for buyers who want a larger square grate, stainless steel construction, and listed certification information. Its Quadrato-pattern grate is removable, and the product details describe a 2-inch central outlet for standard U.S. no-hub drain base systems.
The manufacturer lists a drainage rate of 5.28 to 6.6 gallons per minute and says the grate helps block hair and debris. The drain is made from SUS 304 stainless steel and is listed as WaterMark and CUPC certified. Choose it if those stated details match your project requirements.
Limitation: The stated system fit is specific to standard U.S. no-hub drain bases, so confirm your existing base before purchasing.
Matte Black 4-Inch Square Shower Drain
This 4-inch model is best for buyers who prefer a smaller square grate over the 6-inch options in this list. Its listed kit includes a removable grid, flanged drain base, hair strainer, threaded adapter, O-ring, lifting hook, screws, and expansion tubes.
The product specifies a 2-inch central outlet and a total height of 4 inches. It is described as suitable for an American 2-inch no-hub drainage base system, with possible uses in bathrooms, kitchens, garages, and basements. The listing gives an average displacement figure of 80 liters per minute.
Limitation: Its smaller grate may not suit buyers specifically seeking a 6-inch drain cover; verify the full installation dimensions against your project.
EXF 6-Inch Square Drain With ABS Flange
The EXF drain is best for buyers looking for a 6-inch square grate bundled with an ABS flange and rubber gasket. Its grate is made from SUS 304 stainless steel, and the product description says the matte black finish is intended to resist rust, corrosion, and scratches.
The square lattice pattern is described as supporting water flow and helping prevent pooling. The kit is stated to fit standard U.S. 2-inch drain bases. Choose this option if the included flange and gasket match your renovation plan and you want a straightforward grate design.
Limitation: The listing specifies standard 2-inch drain-base fit; check your plumbing connection and installation needs rather than assuming compatibility.
Dilvii 6-Inch Adjustable Shower Drain
This Dilvii model is best for buyers who need some flexibility in setting grate height to match floor tile. The listing says its threaded adapter adjusts the drain height by up to 1 inch. It also includes a removable grid cover and hair strainer.
The product describes a 6-inch square drain with a 2-inch central outlet, a stainless steel grate, and an ABS drain base. It lists fit for standard U.S. 2-inch and 3-inch PVC, ABS, or cast-iron plumbing connections. The drain is also listed as CUPC certified.
Limitation: The stated height adjustment is limited to a maximum of 1 inch, so check the finished floor depth before selecting it.
WEBANG 6-Inch Reversible Cover Drain
This WEBANG drain is best for buyers drawn to a reversible, 2-in-1 cover that offers a tile-insert grate style. The product name identifies a removable cover and SUS 304 stainless steel construction. Its listed 2-inch central outlet is intended for standard U.S. no-hub drain base systems.
The manufacturer lists a flow rate of 5.28 to 6.6 gallons per minute and says the grate helps block hair and debris. The product is described as CUPC certified. Consider it when the reversible cover design is a priority alongside a 6-inch square format.
Limitation: The listed base compatibility is specific, so verify that your drain system supports this connection before installation.
Buying Guide: How To Choose A Black Square Shower Drain
Which grate size should you choose?
Compare the listed grate dimensions with your layout and the drain opening. This selection includes one 4-inch square model and four 6-inch options. A larger cover may suit a different visual preference, but the grate size alone does not confirm plumbing fit. Check the product’s outlet and base specifications as well.
What plumbing connection does your project require?
Look for the stated outlet size and drain-base compatibility. Several products list a 2-inch central outlet, but their base descriptions are not identical. Dilvii, for example, lists compatibility with certain 2-inch and 3-inch plumbing connections, while WEBANG describes a standard U.S. no-hub drain base system. Confirm the actual connection with your installer or existing drain components.
Do you need a height-adjustable or tile-insert cover?
Dilvii lists up to 1 inch of height adjustment, which may help when matching the drain to finished tile height. The WEBANG reversible-cover model is the choice in this group specifically named as a 2-in-1 tile-insert design. Check installation instructions and cover dimensions before planning tile placement.
Which materials and kit parts matter?
Compare grate materials, included flange parts, strainers, and seals. Several listings identify SUS 304 stainless steel grates. EXF includes an ABS flange and rubber gasket, while the 4-inch drain listing names a hair strainer, O-ring, and threaded adapter. Included components vary, so do not assume every kit contains the same parts.
