Are you wondering what differentiates various sink bowl models? What should you pay attention to when selecting a sink for your project? We encourage you to read the following text, where we highlight the main aspects of choosing a sink bowl, an essential element of any commercial kitchen.

Types of sink bowls

Fundamentally, there are two types of sink bowls:

  • sink and bowls to weld,
  • sink and bowls to overtop – these are electro-polished and have an aesthetically finished edge.

Important parameters when selecting a sink bowl

Drain location

Each customer can choose the location of the drain. At AiFO Components, we offer left, right, and centrally drained bowls.

We also offer the service of punching a hole in the bowl according to the customer’s needs and provided specifications. Upon request, we can also supply a sink bowl without a pre-punched drain.


One of the most critical parameters that allow for the selection of an appropriate sink bowl for your space and project. In our offer, we have many bowls to weld and overtop. Our technical advisors can match the right sink to the neutral furniture based on the provided technical documentation.


The sink bowl can be either matt or electro-polished. In exposed areas where aesthetics and appearance matter, the electro-polished sink bowl is often the preferred product.

Flow direction

The slope enables water to flow to the drain and prevents it from pooling at the bottom of the bowl. Depending on the model, sink bowls have a slope direction towards the corner (the most commonly used solution) or towards the edge.

Radius of rounding

Sink bowls differ in radius depending on the model. This solution facilitates cleaning the bowl and maintaining a high level of hygiene. The absence of rounding, i.e., a right angle, would cause dirt to accumulate in the recess and require more thorough cleaning by the staff. The rounding radius is also very important from the designer’s point of view.

Sink bowls are made of AISI-304 stainless steel. It’s characterized by the required durability in the food industry. It’s resistant to corrosion and substances found in the gastronomy.

Sheet thickness

Commonly, sink bowls with a sheet thickness of 0.8 to 1 mm are used. The difference is significant, especially when punching a hole, so it is not as crucial in the finished product.
