Buying Guide

All tankless toilets are not created equal, much like many other aspects of life. Some will outperform others in performance, while others will appear better. Some will even outlive others.

Some are more expensive than others.

Before you buy a tankless toilet, what aspects should you consider? Here are a few examples:


In general, tankless toilets are pricier, but some are more expensive than others, even tankless toilets. You must consider the cost and the amount of money you are willing to spend before deciding. The cost of repairs and maintenance should also be taken into account. Replacement parts for high-priced toilets are likewise likely to be pricey.


Tankless toilets come in various colours, and we don’t discourage people from trying something new. We can all agree that most toilets are white. White is more hygienic, so it is preferred over other colours. While black toilets are more popular, we recommend sticking with white in this circumstance.

Power Reliability

Tankless toilets are useless without electricity. All of the operations of a tankless toilet are powered by electricity. If you live in a region where power outages are often, you might not get the most out of using tankless toilets.


Comfort is a huge factor when it comes to toilets and tankless toilets. As a result of heated toilet seats, enlarged bowls and seats, comfort/chair height and nightlights, automatic flushes and lids that open and close, etc. Tankless toilets are more expensive because of this. Though some tankless toilets are less pleasant, you will have plenty of options for toilet comfort with tankless models.

Toilet Dimensions

Regardless of the size of your bathroom, tankless toilets look fantastic. Please take your time while considering the toilets and measurements if you have a small bathroom where every square inch is important.

Also, don’t rely solely on the measurements provided by e-commerce companies. In most cases, these are presumably the dimensions of a ship. The toilet’s specifications can be found on the manufacturer’s website, so head over there and get a copy.

The Toilet Rough-in

Before buying a tankless toilet, know how big the rough-in is. The rough-in is the distance between a toilet’s back wall and the centre of the toilet’s drainpipe. A standard toilet’s rough-in is 12 inches long. There are also rough-ins like 10 and 14.

Modern tankless toilets have a 12-inch rough-in as standard. If you want to install a tankless toilet in a bathroom with a rough-in of 10 or 14 inches, you may want to consider purchasing an offset toilet flange.

You’ll need an offset toilet flange to switch from 14-inch or 10-inch rough-in toilets to 12-inch standard rough-in toilets. Find out more about offset closet flanges here.

Water Efficiency

It is not uncommon for toilets to use up to 3 gallons of water per flush. Other people flush their toilets with just 0.8 gallons of water. Over a long time, the amount of water saved is enormous. Purchase a water-saving toilet to save money and the environment simultaneously.

Legal Requirements

In some states, tankless toilets may be unavailable because of legal limitations. As part of the Americans with Disabilities Act (ADA) requirements, public restrooms must have a comfortable seat height (17-19 inches). Any toilets sold in California must consume no more than 1.28 gallons of water every flush.
