Should You Opt for a Commercial Toilet For Your Home?

The sleek design of many tankless toilets is driving homeowners to consider installing commercial toilets in their homes. However, while this seems like a good option, the home is often not set up to adequately handle the needs of a commercial toilet. Here are a few factors homeowners should take into consideration before deciding on a commercial toilet over a more traditional, residential one.

Which Toilet is Right for Your Home?

residential vs commercial toiletsAny discussion about which toilet is best needs to start with how they are different. Residential, or traditional, toilets work by using a tube at the bottom of the toilet bowl fixture (called a siphon). The water coming into the bowl from the tank has to come in at a fast enough rate to pull it down siphon and through the pipes, along with anything else in the toilet.

Residential water supply line pipes don’t provide this type of water pressure and force, so the tank helps by pushing it into the bowl at a faster rate. Residential toilets can work on as little as 10 psi (pounds per square inch).

Commercial toilets, however, rely on higher water pressure provided by larger pipes to flush without the need for a separate tank. The pipes provide water to the toilet at a much faster rate. This makes most homes simply unable to handle the requirements of a commercial toilet without making huge bathroom plumbing changes to the home.

The Importance of The Underground Plumbing System

A factor that doesn’t get taken into consideration as much as it should is the underground pipes for a residential bathroom plumbing system. The pipes needed to flush a commercial toilet are larger in diameter than residential water supply pipes. These pipes must be at least an inch in diameter for a commercial toilet to work appropriately. Residential pipes are usually between half an inch to three-quarters of an inch in diameter.

This means that residential water supply pipes will either fail to flush a commercial toilet or take a significantly longer amount of time to refill. In the worst-case scenario, the water from a commercial toilet being forced into a residential water pipe system can rupture the pipes.

Tankless Toilets And The Bathroom Plumbing System

Tankless toilets rely on residential water supply line pipes to provide the water pressure necessary to cause the flush.

In some cases, where the home’s water pressure isn’t quite strong enough to create a flush, an additional pump will need to be used. This allows homeowners to enjoy the look of a commercial toilet without any of the odor and bathroom plumbing problems. However, in many cases, tankless toilets require power to work.

This means that the toilet will not work in the event of a power outage. Homeowners who are interested in installing a tankless toilet in an area that has a frequent loss of power should make sure to take this into account. Generally, it’s a good idea to work with your local plumbing company to determine what option works best for your home.
