For many years, Americans have lived with toilets that use black water (sewage) tanks to flush waste away. But some advanced toilet systems no longer rely on these tanks, which can be inconvenient and unsightly.
These innovative new toilets don’t use tanks at all; instead, they use water directly from the source to whisk waste away.
These toilets eliminate the need for tanks and piping, reducing installation costs and simplifying future maintenance. They also offer water-saving compared to traditional ones using 4-6 gallons per flush (gpf).
Some of them even offer flushing options including a half-flush option.
The following are top-rated tankless toilets that can save you time and money.

Types Of Tankless Toilets

There are three different types of tankless toilets, each with its own benefits and drawbacks:

Wall Hung Toilet

The wall-hung toilet has its origins in ancient China. It was common for Chinese households to use simple buckets to collect human waste and then carry them out into the streets to be collected and removed from public view. The best example of a traditional wall-hanging toilet can be found at the Temple of Heaven in Beijing, China.

Floor Mounted Toilet

Floor-mounted toilets make up an entire family of plumbing fixtures that all share one thing in common – they rest on top of the floor instead of recessed into it like conventional tanks. They come in both elongated and round designs just like standard toilets and even come in both traditional 2-piece designs as well as newer 1-piece tankless units.

Close Coupled Toilets

Close-coupled toilets are among the most popular choices for bathrooms across North America. They are true hybrids, with one half resembling a classic toilet bowl mounted above the floor while the other half features a drain pipe that is attached directly to the wall or floor nearby. This means there is no need for additional piping between where it will be installed and its final location on either end of this type of unit. There are further subtypes within this style – namely, concealed close couplers which have no exposed fittings on any of their exterior surfaces, fully recessed close coupled toilets which feature an additional inch or so of “protrusion” hidden underneath the floor, and comfort-height close-coupled units which are designed for taller users.

Reasons to choose a tankless toilet

Tankless floor-mounted toilets take up very little space. This means they will fit behind the toilet tank in even the smallest of bathrooms. You can also buy someone who fits well with your decor – all modern floor-mounted toilets feature sleek designs to complement any bathroom style. And the pedestal allows you to install it easily without worrying about finding additional space for storage or without disturbing existing plumbing. These toilets don’t require much electricity and usually operate on low voltage DC power using 12 volts or less – which is another potential energy saver! Additionally, no flushing levers mean water savings while keeping germs at bay. Make sure you have plenty of room between where your tankless unit is going to go and the wall so you can easily access it for cleaning. Also, if your bathroom does not have a floor drain or a floor waste outlet you will need to install one before installation. You’ll also want to be sure that the location of the tankless unit allows for enough tubing between the unit and where it will go on the wall. Some manufacturers recommend having at least two feet of additional space along with 3/4″ water supply line near by- just in case you find yourself needing to reattach something sometime down the road.
The above article demonstrates how these modern innovations such as WaterSense certified toilets made with an EverClean surface protect from bacteria and mold growth, letting us rest easy knowing our product will be hygienic for years to come. These high-tech products are also powerful and efficient, making them a smart upgrade that will save us time and money.

Eco-friendly Features

Tankless toilets have a number of eco-friendly features that make them the perfect choice for anyone looking to save water or money on their monthly hydro bills while also contributing to more sustainable living conditions in your local area.

Saves on Water Consumption

Features To Consider Before Buying A Tankless Toilet

Before you buy a tankless toilet read reviews and consider these features:

Size – Some units are only appropriate for small spaces, while others work well in larger areas
Technology – Units rely on electric or gas heating elements, or more traditional water-based systems, to heat the water up to the right temperature
Water Efficiency – Tanks use a lot of clean water during each flush, which means more frequent replacement. Tankless systems reduce this expense by using much less water for each flush than traditional models
Maintenance Requirements – Some tankless toilets are self-cleaning when flushed, while others require manual scrubbing

Conclusion
There are many different brands and styles of expensive tankless toilets to choose from, but the best one for you will ultimately depend on your personal needs. For example, if your bathroom is tiny or has low ceilings, a floor-mounted unit might worry you about space constraints. If that’s the case, consider buying a wall-hung model instead. Also, think about how often you plan on using the heated seat or other features that might drive up the price tag. So long as you do your research and know what to look out for before purchasing your unit, you can rest assured knowing whatever model you settle on will be well worth its cost in terms of functionality and luxury!
