3-1/2ft Post Style Large Kitchen Sink Basket Strainer - Solid Brass

In this review the Westbrass post style large kitchen sink basket strainer is evaluated as a straightforward, heavy-duty replacement for standard 3-1/2 in sink drains. The bottom line: this strainer is best for homeowners or contractors who want a durable, corrosion-resistant metal unit with a manual turn post to control flow and full brass installation hardware. The single biggest reason to buy is the solid brass construction, which gives a premium feel and better long-term corrosion resistance than many stamped metal alternatives.

Key Features

• Solid brass construction: Built from heavy-duty brass for long-lasting durability and improved resistance to rust and corrosion compared with plated or plastic parts.
• Fits standard openings: Designed for compatibility with most 3-1/2 in sink openings and a rim diameter of 4-3/8 in for easy replacement of existing strainers.
• Turn post flow control: The large center post lets you manually restrict or release draining water by turning the knob, which is handy when rinsing or filling the sink.
• Complete brass hardware: Includes solid brass nuts and washers so the connection is secure and less likely to corrode at the joint.
• Installation guidance: Intended to be sealed with silicone for a watertight fit and to avoid plumbers putty that can harm some finishes.

Who It's For

This strainer suits homeowners, rental property managers, and tradespeople replacing a worn or plastic 3-1/2 in kitchen sink strainer who prefer metal construction and a manual post stopper. The solid brass makeup and included brass nuts make it a good choice where corrosion resistance and a lasting mechanical seal are priorities.

Those who should look elsewhere include people seeking a push-pop style stopper or a model with a built-in rubber gasket system rather than a turn post, and buyers who need a decorative finish guaranteed for long-term paint durability without any reports of wear.

Pros & Cons

Pros

• Durable heavy solid brass body provides a premium, corrosion-resistant alternative to stamped metal or plastic.
• Simple turn post gives a precise, manual way to control water flow without additional mechanisms.
• Includes solid brass nuts and washers for a secure, leak-resistant installation.

Cons

• Some users report mixed durability of the basket and center pin in heavy-use situations, so rough treatment may expose weaknesses.
• The finish may show wear over time for some customers, so it may not match expectations for long-term paint durability.
