A bottom sink protector is a stainless steel protective grid mat used at the bottom of kitchen sinks. Its main function is to reduce direct contact and friction between dishes and the sink bottom by elevating the dishes, while also ensuring smooth water drainage. This product is typically made from welded 304 stainless steel solid wire and features non-slip feet for stable support. It is suitable for protecting and enhancing the functionality of both single and double sinks.
In residential kitchens, rental properties, apartment projects, and light commercial kitchens, this bottom sink protector is widely used to prevent scratches, reduce noise, prevent water accumulation, and extend the lifespan of the sink. It also allows for customized sizing and fitting during project procurement.

1. Standard Size Structure
This Sink Bottom Stainless Steel Grid features a standard rectangular structure, typically fitting sink interiors with lengths ranging from 600–750 mm and widths from 400–450 mm. The overall grid height is usually controlled within the 20–30 mm range, creating a stable elevated isolation layer without significantly reducing the effective washing depth. Dimensional tolerances are controlled to ±2 mm, meeting the consistency requirements for mass assembly in projects.
2. 304 Stainless Steel Material
The main body is welded from 304 stainless steel wire, with a typical chromium content of approximately 18% and nickel content of approximately 8%. It exhibits stable oxidation and corrosion resistance in long-term humid environments. Compared to ordinary iron wire or lower-grade stainless steel, 304 material is less prone to rust or structural embrittlement in environments with repeated hot and cold water rinsing, detergent residue, and mild acid and alkali exposure.
3. Grid Welding Strength
The grid structure is secured through multi-point welding. The diameter of a single steel wire is typically controlled within the 3.0–5.0 mm range. In load-bearing tests, it can stably support a concentrated weight of 20–30 kg, such as cast iron pots, stainless steel cookware, or complete sets of tableware.
4. Anti-Slip Feet Configuration
Multiple anti-slip rubber or silicone feet are evenly distributed on the bottom, typically 8–12 in number, with a single point height of approximately 5–8 mm. This structure ensures overall water flow while effectively reducing direct metal-to-metal contact, minimizing resonance noise when placing tableware, and preventing the grid from shifting during rinsing or operation. This is especially important for residential and apartment projects.
5. Precise Drainage Hole Alignment
A central drainage hole is pre-drilled, with a diameter typically compatible with the standard 90–114 mm sink drain openings, ensuring that the original drainage efficiency is not affected. For project-specific customization, eccentric or irregularly shaped openings can be designed based on the customer's sink drain structure, avoiding secondary cutting and improving overall installation consistency and finished product quality.
1. Home Kitchens
In residential kitchens, the Bottom Sink Protector is primarily used to prevent pots and pans from directly impacting the bottom of the sink. By raising the placement height, it reduces metal dents and noise caused by accidental impacts or heavy objects. For stainless steel sinks, this long-term protection significantly reduces the density of scratches on the bottom, helping to slow down the aging process of the sink, especially suitable for families with frequent washing or open-plan kitchen environments.
2. Rental Properties and Apartment Projects
In rental properties or apartment projects, sinks are used frequently and by multiple users with varying habits. The bottom protection grid serves as a low-cost, replaceable protection solution. Its standardized size and easy installation make it convenient for centralized procurement and rapid deployment in projects, helping to reduce future repair rates and property maintenance costs.
3. Light Commercial Kitchens
In small restaurant kitchens, coffee bars, or food preparation areas, this product can be used to separate food, utensils, and the bottom of the sink, avoiding water accumulation and hygiene issues caused by direct stacking. The 304 stainless steel material offers excellent durability in such environments, suitable for use with commercial-grade sinks, improving overall operational efficiency and cleaning convenience.
4. Kitchen Renovation Projects
During kitchen renovations, the bottom of existing sinks often has minor scratches or localized wear. By adding a Sink Bottom Protector, functional upgrades can be achieved without replacing the sink. This method is cost-effective and easy to install, making it suitable as an accessory in renovation projects to improve the overall practicality of the solution.
A: In a standard design, the product creates a stable water flow layer through 5-8 mm high support feet at the bottom, allowing water to flow smoothly from under the mesh to the drain. As long as the holes are aligned with the sink drain, it will not significantly affect drainage efficiency under normal use. In fact, it helps reduce the blockage of the drain by dishes.
A: It can be used with most rectangular single or double sinks, but the internal dimensions and drain hole position need to be confirmed. For irregularly shaped sinks or those with special drainage structures, a custom-sized version is recommended to ensure a proper fit and stability.
A: The commonly used silicone or rubber feet have an aging resistance period of 2-3 years or more in a normal kitchen environment. If wear occurs, the feet can be replaced individually without replacing the entire product, making it suitable for long-term use and project maintenance.
A: Yes. We can develop corresponding sizes of the Bottom Sink Protector based on the sink model and provide unified labeling in packaging, labels, or specifications, suitable for project procurement or brand channel sales.
A: Due to the stainless steel mesh structure, there are no complex dead corners on the surface, and it can be directly rinsed or removed for cleaning. Compared to directly cleaning the bottom of the sink, this product actually reduces the difficulty of cleaning, making it suitable for high-frequency use scenarios.
