A 3-compartment sink is one of the most necessary equipment for restaurants and food-service business in compliance with FDA. It is like it sounds, 3 compartments set up side by side. The three-compartment sink is crucial for quick and effective manual warewashing.

This system provides the three-sink operation of dish cleaning which includes washing, sanitizing and drying. With proper cleaning agents that have used in each sink, the result will be washed, rinsed and sanitized glass and dishware ready for air drying in the rack.

3 Comp Sink Types

There are 2 basic types based on appearance and space required.

  • Straight / Line Sinks have mostly used in restaurants and food-service business.
  • Corner Sinks have rarely used, and they are more expensive than straight/line sinks.


Space is crucial for food business or restaurants. Must be cautious when you choose the commercial sink for the food facilities. Calculate free area that you can use for installation of the triple sink. The length depends on free kitchen space that you have in a restaurant, bar or coffee shop. The 72 to 93 inches are most used length for the 3-comp sink.


It’s very significant from which type of material commercial sink has made. Sink has typically made from stainless steel 304 and stainless steel 430.

  • The 304 stainless steel is the most common type used in the restaurants. The high percentage of chromium and nickel makes a bright shine for 304 stainless steel. Plus, is very resistant to corrosion and rust. But, it’s susceptible to corrosion caused by exposure to salt.
  • The 430 stainless steel is a much less used than 304 type of steel. It’ has a small percentage of nickel and it’s not so corrosion resistant as 304 stainless steel.


Besides stainless steel, every compartment sink is made from special gauge steel too. It is a measurement of the metal thickness. Lower gauges mean thicker steel. These are the 3 main types of the gauge steel.

  • 14 gauge stainless steel (highest grade) is the thickest material and the toughest. They have the highest durability. It also stands up to hard water.
  • 16 gauge stainless steel (high grade) is a medium grade material and it is appropriate for sinks that require strong legs.
  • 18 gauge stainless steel (good grade) is the thinnest material and suitable for soft water areas.


Depending on the volume of your business or needs and finances, you can buy 3 types of the restaurant sink:

  • Sink without drainboards is ideal for bars, clubs or restaurants with limited space
  • Sink with 1 drainboards makes an area for drying dishes or stacking up dirty ones
  • Sink with 2 drainboards provides space for drying dishes or pilling up the dirty dishes on both sides of the commercial sink

Backsplash Type

The backsplash is an integral part of 3 compartment sink. Backsplash guard is necessary for protecting the wall surface and facilitate cleaning.  Splash dimension depends on the faucet’s holes size. There are several types of the backsplash. From smallest 4.5 inches to the largest 11.75 inches. Most used splash is 7 inches.


Simple fact, commercial sink without faucet is useless. Today, exist so many types, size or designee of the tap. The 2 based faucets are deck mounted (mounted on the top of the sink deck) and wall mounted (mounted through the wall/sink backsplash). Here, we will be dealing with a triple sink faucet. 4 main types of commercial faucet are:

  • Standard swing spout is an elegant, suitable solution, allowing you to move the nozzle to get water into multiple sections.
  • Goosenecks makes more space for a sizable heavy dish.
  • Workboard faucets contain risen escutcheon below the handles and spout. Still, they are efficiencies like a similar standard swing spot or goosenecks.
  • Pre-rinse faucets are best for detail cleaning the blasting food parts of dishes before washing.

Compartment Sink Strainers

Pre-rinse basket and strainers are perfect for preventing drain clogs in industrial kitchen sinks. It also stops food remaining’s and other debris from pilling up in drain lines and flor sinks. The filter is made from plastic, and simple for install.

Triple Sink Accessories

Some of the restaurant sinks contain holes for multiple faucets and some with only one set. Think about the reach of the valve and if you need to have a separate spray rinse next to a tap. In the backsplash, the holes can be drilled to customize the gooseneck, nozzle or pre-rinse faucets. The most suitable 3 bay sinks are with one or two drainboards. They can be used for different purposes, from drying dishes to making free table space.

NSF Certification

It is critical that you can guarantee for water, food and other consumer products on a daily basis. The perfect solution is to have NSF sign on your commercial sink. That means that the products you use fulfilled rigorous standards for public health protection.

Selecting a triple sink certified by NSF you be sure that you can rely on strict standards and procedures during the testing of a quality and other criteria.
