Best Tankless Toilets Reviewed

A tankless toilet is one that doesn’t seem to have a cistern or a flushing tank. When you look at it, all you see is in the bowl. It is time, yet again, for one of our super informative reviews about all things toilet-related! It would be hard to see the popularity of the tankless toilet, so it only makes sense that we take you on a journey behind the scenes and within the walls of how and why the no-tank toilet has become such a raging trend. 

Tankless toilets are so popular today because of their compact, fashionable, and high-tech design. As the name implies, tankless toilets come without a tank. Unlike regular ones that have water in the tanks, no-tank toilets connect directly to the water supply pipes. They use small electric pumps to draw water from the pipes into the bowl. 

These units are a worthy investment that can drastically change your bathroom. Check out our top 10 best tankless toilet reviews to find a unit that works for your home.

How Does a Tankless Toilet Work and What Benefits Does it Provide? 

To better understand how tankless toilets operate, you need to have a good grasp of how traditional fixtures work. To simply put it simply, the siphon uses the forces of gravity to move liquid and waste from one point to the next. The tank creates enough water force to start the siphoning process. 

What Benefits Does a Tankless Toilet Provides

For traditional toilets, the tank is necessary to create enough volume and pressure to move waste. This is because the water pressure going to homes isn’t usually strong enough to provide an adequate flush alone. There are exceptions, which we’ll get into a bit later.

Tankless units work well in buildings with strong water pressure. As we mentioned earlier, they are connected to a direct water line. The amount of water that goes into the toilet is controlled by a special valve called the flushometer.

On the other hand, the benefits that a tankless toilet can provide you are abundant. From an aesthetics standpoint, tankless units provide greater flexibility in design. Tankless units can be much more compact. Most are between 20 and 26 inches long, providing you with plenty of usable space. 

The biggest advantage of a tankless toilet is the freedom it gives you in getting the look you want for your bathroom. The precision flushing mechanism some models offer helps you save water, too.

Currently manufactured toilets, whether tankless or conventional, are required by law to use not more than 1.6 gallons of water per flush. Some more advanced tankless models, however, let you choose gallons used per flush, giving you a water-saving option few conventional toilets can match.
