4 Inch Shower Floor Drain with Flange Matte Black - Easy Drainage

In this review the Yaseingoo 4 Inch shower floor drain is presented as a practical, no-frills solution for homeowners and installers who want faster drainage and cleanable protection against hair clogs. The bottom line: this drain is best for anyone seeking a compact, CUPC certified replacement or upgrade that combines a removable hair strainer with a high flow rate, solving ponding in wet areas while adding a subtle matte black accent to the floor. The writeup focuses on performance, installation, and everyday use rather than decorative excess.

Key Features

• Efficient water flow: The 4 in square top with a 2 in central outlet provides a high flow capability of 30-35 L/min to reduce standing water in showers and wet rooms.
• Removable hair strainer: The mesh grid cover lifts out for quick cleaning, helping prevent clogs and making routine maintenance simple.
• CUPC certified: Certification confirms the drain meets common plumbing reliability standards for residential installations.
• Matte black finish: The embedded design and matte black color deliver a low-profile, modern look that complements many bathroom styles.
• Durable construction: Made from SUS304 stainless steel and an ABS base flange to resist corrosion and provide a stable mounting surface.
• Easy installation: Height-adjustable design with a threaded joint fits standard U.S. plumbing connections without requiring a hub.

Who It's For

This drain is ideal for homeowners renovating a shower, contractors fitting guest bathrooms, and DIYers who need a reliable, compact drain that prevents ponding and handles hair buildup. The removable strainer and solid flow rate make it especially suited to family bathrooms and rental properties where low-maintenance performance is valuable.

Those looking for ornate decorative drains, larger commercial drainage systems, or nonstandard outlet sizes should consider other options. Also, buyers needing finishes other than matte black or specialized trap features should check alternate models.
