Top-Fix Polished Steel 90mm Kitchen Strainer Waste c/w Overflow

The Top-Fix Polished Steel 90mm Kitchen Strainer Waste with Overflow is a smart and practical addition to any kitchen sink setup. Built for durability and functionality, it combines sleek style with peace-of-mind features to help keep your sink running smoothly and safely. Made from polished stainless steel, this strainer waste not only looks sharp with its shiny, modern finish but also resists corrosion and stains—ideal for the demands of everyday kitchen use. The polished surface makes it easy to clean, while also giving your sink a professional, high-end look. With a 90mm diameter, it’s perfectly sized to fit most standard kitchen sink waste outlets. The wide opening helps ensure quick water drainage, especially useful during heavy use like washing up after a big meal. The strainer basket helps catch food particles and other debris before they head down the drain, reducing the risk of blockages and keeping your plumbing in good shape. What sets this strainer apart is its integrated overflow connection. If your sink fills up too much—perhaps because someone left the tap running or forgot about soaking dishes—the overflow feature safely channels excess water away, helping to prevent flooding or damage. This is a top-fix design, meaning it can be installed from above the sink, making fitting easier and more convenient, especially in tight spaces.

Frequently Asked Questions

What does “top-fix” mean for a strainer waste?

Top-fix means the strainer can be installed from the top side of the sink rather than underneath. It’s a much easier installation process, especially when access below the sink is limited.

Is this strainer compatible with all kitchen sinks?

This strainer waste is designed for sinks with a 90mm waste hole, which is a common standard. If your sink has that size fitting, it should be compatible.

Why do I need an overflow feature?

The overflow acts as a safety mechanism. If the water level in your sink rises too high, it will be redirected through the overflow outlet, preventing accidental flooding or spills onto your kitchen worktop and floor.
