Is the Stainless Steel Kitchen Sink Going to Be Phased Out? Not Really.

Mar 15, 2026

Today, I want to discuss the topic of stainless steel kitchen sinks with everyone. It's simple if you just need something for cleaning – you can be casual about it. But if you want a sink that is safe, beautiful, durable, and performs excellently, you need to consider some key points. To help you avoid buying a poor-quality stainless steel kitchen sink, let me explain.

1. Sink Materials:

① Ceramic Sinks:
Ceramic sinks are heat-resistant, aging-resistant, and have a high aesthetic appeal. Their biggest drawback is that they are very hard but brittle and prone to breakage. Ceramic sinks are quite heavy, so installation requires choosing a cabinet and countertop with good load-bearing capacity.

② Artificial Quartz Sinks:
Artificial quartz and granite sinks on the market fall into this category. They come in a wide variety of colors, offering many choices. However, their corrosion resistance is very poor. For example, soy sauce or strong tea can easily penetrate, causing stains that are impossible to remove. Their hardness is also insufficient, making them prone to scratching.

③ Stainless Steel Sinks:
They come in various styles, are easy to install, easy to clean, corrosion-resistant, and have a long lifespan. For most Chinese households, stainless steel sinks are summarized as the most cost-effective and durable choice.

Stainless steel sinks are also divided into machine-made sinks and handmade sinks:

Machine-made Sinks: These are stamped sinks with no welds, low material consumption, and a smooth, flat surface. The manufacturing process is relatively simple. The drawback is that the thickness of the basin's stainless steel is generally only around 1mm, which is quite thin. The advantage is their low price.
Handmade Sinks: These use steel plates processed and then welded by hand, so welding marks can be seen. The thickness is generally around 3mm, making them heavier than machine-made sinks, more durable, and aesthetically pleasing. The quality is also better.

④ Nano-coated Sinks:
These sinks with "nano-technology" processing are actually treated through electrolysis, involving high temperature to combine chemicals with the stainless steel surface. The normal process involves making the stainless steel sink first, then sending it to a plating factory for processing. After processing, there is typically a coating thickness of about 0.2mm. In the short term, this provides oil resistance, stain resistance, and scratch resistance. However, over time, once scratches appear on the product, the coating will peel off, leading to rust and corrosion.

⑤ Stainless Steel Materials:
Common stainless steel materials for kitchenware include 201, 304, and 361. They look almost identical from the outside, but their properties and prices differ significantly:

201: Also known as medium carbon steel, high in manganese, prone to rust and corrosion; low in nickel, corrosion resistance is inferior to 304, and it's not considered food grade. Some illegal merchants might pass off 201 as 304.
304: Also known as 18/8 stainless steel, its composition is approximately iron with 18% chromium and 8% nickel. Its corrosion and rust resistance are better than 201. It is the most widely used stainless steel material currently and can meet food-grade standards.
316: Also known as 18/10 stainless steel, its composition is approximately iron with 18% chromium, 10% nickel, and 2% molybdenum. It is the most expensive among these materials and offers the best corrosion and rust resistance. 316 is generally used in some high-end equipment, such as aerospace, food machinery, and high-end kitchenware.

304 VS 316:
The key difference lies in the fact that 316 stainless steel contains molybdenum. The addition of molybdenum enhances its corrosion resistance. Because molybdenum is a transition element with high corrosion resistance, it also gives 316 stainless steel high-temperature resistance up to 871°C.

Western developed countries have very strict requirements for stainless steel tableware, mandating that stainless steel in direct contact with food must contain at least 16% chromium. This is a very authoritative reference. For health reasons, the sink material should be at least 304. 316 is not necessary, firstly because the cost increase is too high, and secondly, its superior corrosion resistance may not be fully utilized in a home kitchen environment.

2. Sink Shape Design

① Right-Angle Sinks: The four corners inside the basin are 90 degrees. Cleaning can be troublesome as dirt easily accumulates. Functionality is not affected, but the price is much cheaper than rounded corner sinks.
② Rounded Corner Sinks: The four corners inside the basin have a curvature. Rounded corners are easier to clean than right angles. The price is higher than right-angle sinks.

3. Single Bowl OR Double Bowl?

Single Bowl: Large capacity, can easily accommodate kitchen utensils for cleaning. However, the function is singular, and tasks cannot be separated. Suitable for small kitchens or people with low requirements for task separation.
Double Bowl: Having two sink openings. The biggest advantage over a single bowl is spatial separation – one for washing dishes, one for draining water. You can perform two tasks simultaneously, efficiently, without interference. However, the usable area of each individual bowl is smaller, making it difficult to fully submerge large items like pots for cleaning.

4. Top-mount, Flush-mount, or Undermount Sink?

Top-mount Sink (Drop-in): Very simple to install, saving time and effort. Generally, you just cut the countertop according to the sink's dimensions, with no high technical requirements. The drawback is that the area around the kitchen sink easily collects water and dirt, and the silicone sealant can turn black and moldy.
Flush-mount Sink: Also called level mounting. The rim of the sink is flush with the countertop surface. The process is slightly more complicated as grinding is required.
Undermount Sink: The sink is mainly glued underneath the countertop. It leaves no messy edges, is easy to clean, and convenient for hygiene. Water on the countertop surface can be wiped directly into the sink.

5. Characteristics of Surface Finishing:

If you want aesthetics, you can choose an artificial quartz sink. For economy and durability, choose stainless steel, specifically SUS304. If the kitchen is too small, a double bowl is really not suitable; a large single bowl is highly recommended – you can wash whatever you want. A single bowl can also function like a double bowl by adding a draining basket. A handmade sink with rounded corners and a brushed finish is durable and worry-free. Don't install a top-mount sink, or the blind spots will be annoying!
