If saving space while retaining the same comfort level is your ultimate goal, then a round bowl toilet is your go-to model.

These toilets max out at 28 inches. Thus, they could save you up to 3 inches lengthwise compared to an elongated bowl. And they do so without compromising their performance, aesthetic properties, and comfortability.

This guide brings you some of the best toilet picks that lead in terms of flushing, cleanliness, and quietness.

Best Round Toilets Buying Guide

A toilet is among a few other household commodities that we don’t buy on a daily basis. So, it’s understandable if you don’t know where to start. Here are a few things that we think might help make your purchase easy.

Water Saving Capabilities

By federal law, modern toilets use utmost 1.6 gallons per flush. WaterSense – labeled models save more water by using 1.28 gallons per flush. These toilets will go a long way in saving you money and conserving water.

Flushing System

There are 2 major options here: pressure assisted and gravity assisted toilets.

Pressure assisted
systems use pressurized air to boost the flushing performance. These systems are known to reduce the likelihood of clogs. However, they are expensive and maintenance can be costly. They can also be quite noisy.

Gravity assisted flushing systems harness the power of gravity to create enough flushing force. While they aren’t the most powerful, they still get the job done especially if the trapways have been redesigned to remove any chocking points. They are also quiet, less expensive, and easy to maintain.

Comfort Height

The standard height for toilets is approximately 15 inches. This height is ideal for short people. Health experts also recommend it to people with constipation issues.
However, with the increased cases of back and spinal pains, this height has lost its popularity.

Most people today prefer toilets with 17-19 -inch seat height. This height has been dubbed ‘Comfort Height’ since it makes sitting and getting up easy and painless.

Dual or Single Flush

While the choice between these 2 flush modes is a personal preference, we would vouch for the dual flush. This is because it gives you the freedom to select the amount of water you want to use per flush.
Take note though. The dual flush mode may have a learning curve to it. It can also be a tad bit hard to get repair parts for its system since these toilets are not common. Learn more about single and dual flush modes here..

Which Is Better Round Or Elongated Toilet?

There has been lots of rants on which is the best  bowl design between these 2.

Elongated vs Round Toilet

Round bowl toilets are known for their space saving design. Most of these toilets have a maximum depth of 28 inches and might, therefore, offer you more legroom.

On the other hand, elongated bowl toilets max out at up to 31 inches at the front. The consensus is that these extra inches add comfort and convenience when using the toilet.

However, do know that these 3 additional inches may also stand in your way of meeting your municipality’s bathroom building codes. They could also hinder you from installing another fixture right in front of the commode.
