Kitchen Sink Obsolescence List: These 6 Outdated Designs Are Being Ditched, and the Third One Harbors Dirt and Grime the Worst!
The design of a piece of stainless steel determines the cleaning efficiency and quality of life in Chinese kitchens.
The kitchen sink, a vessel we interact with daily, is undergoing a quiet revolution. Once-popular stainless steel double sinks, elegant ceramic sinks, and seemingly convenient sinks with built-in drain racks are now losing ground amidst a wave of rational consumption.
According to the “2025 China Kitchenware Consumption Trend Report,” market demand for removable kitchenware increased by 137% year-on-year, while inquiries for traditional sinks plummeted. As Chinese families’ awareness of health, efficiency, and space utilization increases, designs that harbor dirt, obstructive dividers, and fragile materials are finally being consigned to history.
The Double Sink Dilemma: A Spatial Prison in the Age of the Big Pot
Stainless steel double sinks, once considered the epitome of functional zoning, have revealed their fatal shortcomings in modern kitchens. With large-caliber woks and steamers becoming standard equipment in Chinese households, the narrow single double-bowl sink feels like a spatial prison. Pots over 32 cm (11.5 in) can’t be washed flat, and forcing them in only creates a splattering mess.
Even worse is the barrier of the shelf. When washing long cutting boards, users are forced to work at a twisted angle, causing water to flow along the shelf’s edge onto the countertop. A modern solution addresses this pain point: a single sink over 75 cm (11.5 in) with a removable drain basket. This allows for flexible partitioning while instantly freeing up space. Washing pots is effortless, while the basket hangs suspended to drain water while washing vegetables—this is the wisdom needed for real-world scenarios.
Ceramic sinks: A fragile trap beneath an exquisite exterior
Ceramic sinks were once popular for their smooth, mellow texture, but fell from grace due to practical shortcomings. Their Mohs hardness is only 5-6, far below the 6-7 of stainless steel, making them prone to cracks or chips from impacts with pots and bowls. Even more challenging is glaze maintenance: oil seepage causes yellowing, and scale deposits create mottled white marks, drastically reducing aesthetic appeal within three years.
Compared to current mainstream materials, nano-coated stainless steel has a contact angle exceeding 150°, achieving a “lotus-like self-cleaning effect.” Granite composite sinks have a Mohs hardness of 7, are scratch-resistant, and have a 99% antibacterial rating. When pragmatism trumps visual appeal, ceramic sinks are relegated to a niche, retro market.
Built-in Drain Rack: The Ideal Collapses in Reality
The integrated drain rack design had beautiful initial intentions, but in reality, it has become a breeding ground for bacteria. Long-term water accumulation in the drain area causes the metal bracket to rust, breeding pathogens like E. coli on contact with tableware. Even more frustrating is the space encroachment—the drain rack takes up 30% of the main sink’s operating area, interfering with dishes when washing vegetables.
A modern solution solves this problem with a “separate” design: a retractable silicone drain rack that hangs on the side of the sink and unfolds and folds away when needed, completely eliminating unhygienic corners. Oulin’s “basin-in-basin” series even features an innovative snap-on mechanism that allows for instant switching between the drain basket and main sink. Freely combining functional modules is the ultimate solution for small kitchens.
Shallow Sinks: The Originator of Splashing Nightmares
Shallow sinks less than 18cm deep are the root cause of kitchen countertop flooding. Fluid dynamics experiments show that when the water spray height exceeds the sink depth by 2cm, the splash rate increases by 70%. Every dishwashing experience is like a water battle, with accumulated water seeping into the cabinets and eventually causing the wood to expand and deform.
The modern sink depth standard has been upgraded to the optimal range of 21cm. Moen labs have verified that increasing the depth by 3cm reduces water flow noise by 6dB while blocking 95% of oil splashes. When used with a pull-out faucet, the rinsing coverage area increases by 40%, making it easy to remove stubborn pot stains.
Colored Acrylic: The Double Hack of Fading and Burn Marks
Colored acrylic sinks, like a fleeting fashion item, quickly show their failings in the harsh environment of the kitchen. Bright colors fade and turn pale within six months under direct sunlight; leaving hot pots over 80°C will leave permanent burn marks. Even more devastating is the material’s lack of strength, which can lead to dents caused by heavy drops.
The high-end market is turning to material technology for breakthroughs. Gun-gray PVD-coated stainless steel uses vacuum ion plating technology, allowing the color to penetrate the substrate molecular layer, increasing wear resistance by three times. Pure black granite sinks withstand temperatures of 400°C, allowing hot pots to be placed directly on the sink without any issues. When aesthetics come at the expense of practicality, consumers quickly abandon them.
Above-Counter Basins: The Ultimate Host of Mold Strips
Above-Counter Basins are a favorite among retailers due to their easy installation, but structural flaws have led to countless tragedies. Glass sealant has a 100% mold growth rate in humid environments, and mold penetrates the colloid and cannot be removed. Even more insidious is the danger of water seepage—water seeping into cabinets through cracks. Long-term exposure can cause the panels to shatter, leading to repair costs easily exceeding tens of thousands of yuan.
The latest generation of installation technology completely eliminates blind spots. The undercounter sink joint is lowered 2cm, allowing wastewater to be scraped directly into the sink. Seamless one-piece molding technology uses hydraulic stretching to fuse the countertop and sink, completely eliminating the seam. Bolanggao’s “floating sink” even features hidden brackets, creating a visual illusion of a work of art floating above the countertop. Beauty and practicality shouldn’t be a matter of choice.

Market data suggests the direction of change: Oulin’s “basin-in-basin” series of snap-on sinks has seen a 200% year-over-year increase in sales. Bolanggao’s floating sinks free up 15% of vertical space in small apartments. Smart sinks equipped with AI diagnostic chips automatically detect blockages and seal aging.
When German brand Platinum tests carbon fiber-reinforced ceramics and Vatti achieves 150° super-hydrophobicity, those seams that harbor dirt, awkward double sinks, and moldy, discolored rubber strips will eventually become a bygone era.
The evolution of sinks is, at its core, a triumph of practical wisdom over false sophistication.
