FoodSafe floor drains and floor sinks collect excess liquid, keeping floors free of standing water and debris; dry floors prevent bacterial growth and lower contamination risks. Floor sinks provide dedicated drainage to specific areas or equipment and help maintenance staff keep floors clean. Floor drains keep whole rooms or large zones dry by diverting water from everyday activities and process flows.   ## What is a Floor Sink? [![FloorSink](https://blog.foodsafedrains.com/hs-fs/hubfs/FloorSink.png?width=872&height=491&name=FloorSink.png)](https://foodsafedrains.com/products/floor-sinks) **Floor Sinks** are floor-mounted service sinks, typically deeper than a standard floor drain. Floor sinks handle indirect waste, such as water from dishwashers or cleaning operations, and can accommodate more water and debris than standard floor drains. They usually have a top grate and an integrated strainer basket inside. These features help to trap and separate solids and liquids, preventing underground plumbing from clogging. A floor sink is a type of floor drain designed for commercial applications, including the food and beverage industry. But wait, floor sinks are a type of floor drain!? Wasn't this article supposed to explain the differences between a floor sink and a floor drain? The surprise twist is that a floor sink is just a specialized type of floor drain! Let’s examine what a floor drain is together to better understand what we mean. ## What is a Floor Drain? ![IMG-5114\_web](https://blog.foodsafedrains.com/hs-fs/hubfs/IMG-5114_web.jpg?width=2860&height=1908&name=IMG-5114_web.jpg) Floor drain is a blanket term used to refer to many types of visible openings meant to collect water and divert it into underground plumbing. There are many different types of floor drains but some of the most common are - Floor Sinks - Area Drains - Trench Drains - Slot Drains Floor drains are made to fit flush with the finished floor. The floor is often sloped towards floor drains. Floor drains provide a purpose-built channel for liquids to enter, keeping floors dry. Floor drains can be made from many materials, including plastic, concrete polymer, aluminum, and stainless steel. Food and beverage facilities should always install stainless steel drains, as other materials can be difficult to clean hygienically. Non-hygienic drains can trap debris, leading to bacterial growth. This poses a contamination risk and can lead to foodborne illness. For this reason, food facilities should always install floor drains (like floor sinks) made from food-grade stainless steel.   ## How Does a Floor Sink Compare to a Floor Drain? ![DSC\_7370](https://blog.foodsafedrains.com/hs-fs/hubfs/DSC_7370.jpg?width=1024&height=684&name=DSC_7370.jpg) We get this question a lot, but because a floor sink is a type of floor drain, you cannot compare the two. What you can do is compare a floor sink to other types of floor drains like area drains, trench drains, and slot drains. A floor sink is most comparable to an area drain. A floor sink typically holds more volume than an area drain and serves a different purpose. An area drain is a square or round drain meant to drain areas of 400 square feet or less. The floor around an area drain slopes towards the drain. This allows liquids to flow towards the drain and enter the underground drainage system. A floor sink is purpose-built to drain a specific piece of equipment, like a dishwashing sink or a processing machine. It isn't made to drain the entire floor; it is meant to handle high volumes of liquid and debris from a single source and to filter it before it enters the underground plumbing. Because of this the floor is generally not sloped to a floor sink like it is to a floor drain. ## Where are Floor Sinks Used? ![AdobeStock\_165378043](https://blog.foodsafedrains.com/hs-fs/hubfs/AdobeStock_165378043.jpeg?width=5000&height=3334&name=AdobeStock_165378043.jpeg) Floor sinks are usually placed in areas that could encounter more solids or higher volumes of liquid than the rest of the floor. They provide a secondary basin and strainer system to accommodate water before it enters the underground plumbing. An example is a restaurant dishwashing sink. Placing a floor sink below the drain pipe of a dishwashing sink creates an air gap and filter system between the sink and underground plumbing. This prevents both clogs and backflow, reducing maintenance and contamination risks.  A floor sink is ideal for commercial appliances requiring drainage. They are necessary if the equipment requires an air gap per local codes and regulations. An air gap is a break between the plumbing on the bottom of a piece of equipment and the underground plumbing. Air gaps allow for easier cleaning and greater modularity than hard connections. They also prevent backflow. Backflow is when a vacuum forms in the plumbing, causing dirty water to flow backwards into the sink or other equipment. ## Area Drains **Area Drains** are point drains designed for either indoor or outdoor use. They are generally constructed with a removable grate/lid to allow for access and cleaning of the underground piping.  Area drains are normally round or square and can vary from a few inches in diameter to a foot or more. FoodSafe Drains offers a wide variety of [area drains](https://foodsafedrains.com/product-category/foodsafe-drains/area-hub-drains-2/). ### FoodSafe Drains Advantage - T304 and T316 stainless steel construction - Hygienic no-niche construction - Forklift rated - Integrated strainer basket for easy cleaning - Tamper-proof designs available ![FSADR512-84CONE-(JUST-LID-EXPLODED)\_web-1](https://blog.foodsafedrains.com/hs-fs/hubfs/FSADR512-84CONE-(JUST-LID-EXPLODED)_web-1.png?width=600&height=600&name=FSADR512-84CONE-(JUST-LID-EXPLODED)_web-1.png) ## Trench Drains A trench drain is a linear drainage system that quickly and efficiently removes excess surface water by using a trough-shaped channel covered with a grate. FoodSafe Drains offers a wide variety of [trench drains](https://foodsafedrains.com/trench-drain-systems/). ### FoodSafe Drains Advantage - T304 and T316 stainless steel construction - Hygienic, no-niche construction - Forklift-rated - Large openings allow for higher flow rates; systems can be 6" or 12" wide. - Compatible with clean-in-place technology.
