What to Consider When Buying the Best Toilet that Flushes Everything – Buying Guide

The following are some of the most important factors to look out for when choosing the best toilet that flushes everything.


Size is one of the main things to consider when purchasing a flushing toilet. Whether it is a new installation or you are looking for a replacement, it is important you get the correct measurements so that it fits perfectly in your bathroom. The distance between the floor drain to the wall and the height are two important measurements to keep in mind.

Type of Toilet


Flushable toilets come in two types; one-piece or two-piece. One-piece toilets have a toilet tank and bowl fused together. This design creates a seamless and sleek outlook that is appealing to most people. Besides, they are compact thus saving bathroom space while they don’t have crevices that make cleaning difficult. The drawback with one-piece toilets is that they are a bit cumbersome and pricey.

The two-piece toilets feature two separate parts and are the most common toilets that flush everything. Moreover, they are affordable compared to the one-piece models, easy to transport, easy to install, and widely available replacement parts. However, this toilet design is difficult to clean compared to one-piece units.


The height of the toilet you want to buy is another important consideration. Most flushing toilets range between 14 to 16 inches in height, which is the chair height seating. There are also toilets that come between 17 and 19 inches are ae commonly referred to as “comfort height” or tall toilets. This extra height makes it easier and comfortable to sit on. However, if you are with limited mobility then you should consider going for ADA certified which come at 16.5-inch high making them easily accessible.

Flushing Technology

Toilet flushing technologies have tremendously evolved over the years. Flushing toilets come with either of the following flushing technologies;

Pressure-assisted toilets: The pressure-assisted flushing systems come with a pressurized tank inside the unit’s water tank that increases the water pressure flushing into the bowl. While they are excellent in flushing everything, this flushing system is a bit noisy and requires extra maintenance.

Gravity: Most flushing toilets come with a gravity flush system. These toilets hold water in a tank and take advantage of gravity to create flushing pressure that clears everything in the bowl into the trapway. Gravity flush toilets are the easiest to maintain.

Double-Cyclone: This flush system is common in TOTO flushing toilets. However, the best part is that it uses 1.28gpf thus saving more on the water bills. This type combines both gravity flush and pressure-assisted flushing functionalities. Besides, toilets with a Double-Cyclone flushing system come with two nozzles instead of the standard rim holes common in other flushing systems.

Dual-flush: This flush system is a recent technology that is, without a doubt, is gaining popularity among flushable toilets. This system allows users to choose between partial and full flush. As such, you can use between 1.1 and 1.6 gallons of water per flush depending on the waste you want to flush. However, a 1.1-gallon dual flush system is the best option for flushing down fluid waste.

Noise Level

If you are intending to install your toilet near your bedroom or baby’s nursery, then noise level is something you should consider. Based on the flushing system the toilet comes with, you can easily estimate the noise level. Gravity flush toilets are said to be the best with the lowest noise levels. Some toilets with special fill-valves equally deliver quiet flush. Moreover, get a toilet model with soft lid closure as opposed to one that slam shuts.


The material construction of the toilet has a great impact on the quality and durability of the unit. Toilets made from ceramic material are overall fragile than those made from vitreous china. There are also models with EverClean surface finish to prevent skid marks. High-end toilet models are made from high-end materials that guarantee durability and reliability.

Final Thought

Evidently, when it comes to choosing the best toilet that flushes everything, there are plenty of options in the market in a wide range of styles and at prices to suit any budget. So, if you are in the market shopping for a new toilet that flushes everything, but you can’t decide which model to go for, any of our picks in this review can be a great place to start looking.
