Entering your washroom in the morning and finding out that your drainage system is all messed up.

Isn’t it enough to give you a bad day vibe? Have you ever thought about how both bathroom essentials somehow complement each other?

Both of these accessory’s help maintain your drainage system and keep your water passage in a good flow.

The floor dink and floor drain both perform covalently to help keep the passage of water at a good pace. 

Now, you might be wondering if they both are important, what is the main difference between them.

Right? They have different functions and carry some of the properties that differ and make them different from each other.

Today in this post, we will be sharing the most asked comparison, ‘floor sink vs floor drain‘, so that you can easily identify the functions they carry.

Moreover, we’ve added some tips for maintenance that will help you keep your drain system in a good manner.

Floor Sink 

A floor sink is typically found in commercial settings such as restaurants or shops. A floor sink has two openings, one for draining water and for debris to drain into the drainage system.

Because of all the pipes that come up through the floor, floor sinks take up more space underneath than most other types of sinks.

If you stood side by side and used these two types of equipment, the difference in height between an average person and a person six feet tall would be about four inches.

The floor sink comes with one or two bowls that drain the water via an outlet at the bottom of each bowl. The most common floor washing machine has a large bowl that opens into a single sink beneath it.

This allows for easier cleaning by removing only one section rather than both bowls at once, so you must separate them from their traps before removal.

However, some models have two smaller bowls connected to separate doors, allowing service to be performed without removing the entire unit from its location on the lower floor.

These appliances typically have separate taps for hot and cold-water pipes, allowing them to be turned off without having to turn off all water pipes for repair or replacement work.

Floor Sink

It continues to provide access for maintenance as needed and good drainage from surrounding areas in the event of leaks after installation until they can be properly repaired later, after working safely under these units without causing additional damage to other places nearby. Flooding is taking place below.

Floor Drain 

A floor drainage system is an essential component of all basement or crawls sanitary space systems. It is useful for collecting dirt, debris, and other debris flushed down the toilet or sink.

Before entering the building’s waste management system, all collected water must be pumped out of the sink.

A floor drain system can assist in removing excess liquid from your home or business. And, because they are inexpensive, it is worthwhile to add one to your property right away.

Cleaning your floor drain regular is critical for the health and safety of your home or business.

Water will collect if you do not clean it, creating a breeding ground for mold and bacteria.

The first step is to clean the stagnant water around the bottom of your toilet or sink with towels. Then, using gloves and pliers (or something related), remove anything important enough to obstruct things further down the tube, such as hair bands or cotton swabs that have become stuck to them over time.

Tips for maintaining floor drain 

Maintain and clean the clogs

On your floor, various dirt, from pet hair to dust mites, can accumulate. There is a chance that the floor drain will become clogged if it is dirty.

The first sign of a clogged drain is slow flow. To reduce the risk of flooding, clean up the blockage as soon as possible if it is discovered.

Typically, a pair of powerful piston pumps can clear this minor clog. Try pouring a baking soda and vinegar solution down the drain if that doesn’t work.

Floor Drain

If you have a spiral drain, pull the cable down until it meets resistance, then turn the cable and roll back everything clogging the drain.

Try to fill traps

Indoor floor drains collect overflow drains from sinks, toilets, bathtubs, water heaters, washing machines, and other plumbing fixtures.

Outdoor floor drains quickly drain water from surfaces during and after heavy rain.

Floor drains, whether indoors or outdoors, are designed to direct water efficiently and safely into a drain or municipal rain drain, keeping the floors dry and the rooms from flooding.

The purpose of siphons is to keep sewer odors and gasses from entering your home through the drain. 

Fill or air these siphons regularly to ensure they are full of water and working properly – simply pour one liter of water into each floor drain to keep them full.

This is also a good way to ensure that the sewer is open and that water is flowing through it. The water fills the siphon, creating a barrier between your home and the sewer system.

Clean the drains

Check and clean your drains at least once a quarter for dirt.

If necessary, use a safe liquid drain cleaner, or hire a professional plumber to clean your drains if they haven’t been cleaned in a long time.

It is also a good idea to hire a professional sewer cleaner once a year to avoid clogging and keep your sewers running smoothly.

Floor Sink Vs Floor Drain 

A floor drain is typically a hole surrounded by a grid. It is covered at the surface’s deepest point, graded but relatively shallow.

Water runs down the drain. Floor drains run the length of the floor. It can produce anything. There may be more than one drain, and there must be several slopes in this case.

The sink, on the other hand, is a more subtle element. It includes pages and follows a set format. You can use it to wash your hands or feet. 

The sink has a sink-like shape and a specific water capacity. It can also act as a buffer for the water that falls.

Floor Sink Vs Floor Drain 

Floor sinks are typically used where an air gap is required for equipment drains, such as B. in commercial restaurant equipment.

They do have some storage capacity and, in most cases, a drain strainer and a removable grille for servicing the unit. 

Floor sinks are also larger than most floor drains, measuring 12″ x 12″, with drains typically measuring 4 or 6″ in diameter, and are located on the same level as the adjacent floors.

I installed a floor sink as part of a food court renovation project this year.

Do I need a floor drain in a commercial bathroom?

Yes, this is required in a commercial restroom. Excess water is drained through the floor drain. It also eliminates odors from the toilet, urinal, or sink and adds a small amount of water after each cleaning.

To reduce evaporation, you can also add mineral oil. They use memory rubber stair seals, which you can supply or supply stair primers.

The floor drain is hidden beneath a sturdy partition. This will keep people from urinating down the drain.

If you’re putting in a floor drain, make sure it’s at least 2 inches per square foot. This factor keeps your commercial restroom sanitary and odor-free.


Keeping your floor drains moving and in working order is very important as these are mandatory to keep your location safe. Besides all the factors mentioned in our guide entirely focusing on ‘floor sink vs floor drain’, both of these factors are important for our drainage systems. If any of them is trapped in any fault, the entire drainage system will and can collapse. So, our suggestion says to wisely choose your washroom accessories to make sure everything is alright.
