1. The transverse length of the sink
It is generally related to the number of bowls in the sink. In other words, the more bowls or wings will lengthen the length of the sink.
Generally speaking, the length of a single bowl sink is about 1000px, the double bowls is about 2000px, and the three bowls is about 2750px.
2. The longitudinal length of the sink and the table top.
Before buying a sink, measure the width of the table top.
The width of the sink should be about 10-375px (250px is usually enough) smaller than the width of the table top.
For example, the table top size of the kitchen cabinet is 1250px-1500px, and the width of the sink should be 1075px-1200px.
Because if the edge of the sink and the table is too wide, it is not beautiful, and it is very tiring to use it.
If it is too narrow, when the sink is filled with water, the table top is likely to break because the edge is too narrow to bear the weight of the sink.
3. Sink Depth
The suitable sink’s depth for families is generally 180mm-200mm, which has the advantages of large capacity and splash prevention.
The deeper the sink not the better.
In fact, it is seldom necessary to fill full water when washing. If the bowl is too deep, filling it will wastes water and time.
If you fill too little water, you have to bend over to clean the tableware, which is very tiring to use.
However, the bowl is not good to be too shallow. Because it is easy to spill water.
Generally speaking, the maximum allowable range for people of different abilities is 150mm-210mm, which is more reasonable, and 180mm-200mm is the best for ordinary people from a practical perspective.
4. Treatment of Inner Corners
The inner corners of the high-quality sink are close to 90 degrees. The vision inside the sink is wider, the volume of the bowl’s body is larger, and the use area of sink can be increased.
5. Thickness of Stainless Steel Sink
Good stainless steel sinks are made of relatively thick plates, preferably between 0.8-1.0mm, and the thickness of the bowls’ bottom should reach 1 mm.
So that 304# stainless steel is selected to make the sink tough.
If the sink is too thin, it will affect the service life and strengt, otherwise it will easily damage the tableware.
The thickness of 0.8-1.0mm can prevent various porcelain vessels from being damaged due to impact and the like to the greatest extent. However, ordinary low-grade water sinks are 0.5 mm-0.7 mm.
The thickness can be distinguished by weight and whether the surface is flat or not.
Because the water sink has been edge treated, it is difficult to see the thickness at once. The simplest method is to press the surface of the water tank slightly. If you press it, the material is very thin.
Of course, it is more convenient to have vernier caliper and screw micrometer.
6. Edge thinness of sink.
The light, thin and skillful edges enable the sink to obtain the maximum washing space and the minimum appearance size.
For a long time, people believed that the thicker the edge of the sink, the better, so that water would not splash out.
This is actually a misunderstanding.
In fact, whether water will splash out depends only on the depth of the sink.
If the thin edge of the sink is exquisite in workmanship, it can be well matched with the table top to prevent water seepage at the joint.
Even if water drops and debris fall onto the table top, it can be easily wiped into the sink with a rag.
Therefore, pay attention to the flatness of the thin edge when purchasing, because the thin edge requires relatively high processing technology, and the thinner the edge, the harder it is to be smooth.
7. Surface Smoothness
It is the most intuitive standard for testing the quality and grade of water sinks.
Keep the line of sight parallel to the sink plane for inspection. The edge of the sink shall not protrude or warp, and the error shall be less than 0.1 mm.
Poor flatness will not only affect the appearance, but also easily cause water seepage and scale accumulation.
The high-quality water tank has a flat surface, soft luster, oil stain resistance, easy cleaning and wear resistance.
When you buy a sink, you can touch the wall of the basin with your hands to see if there is a bulge. A good sink does not have a bulge.
8. Stainless steel sink material
Stainless steel is a kind of ferroalloy. The specific gravity of steel is 7.87.
Heavy metals such as nickel and chromium are added to it. The specific gravity of these metals is higher than that of steel, so the weight is heavier
If it is fake or inferior stainless steel, such as chrome plated steel plate, the weight will be light.
This is also an important and operable method to check the quality of the water sink.
