What to Consider When Choosing the Best Round Toilet for Small Bathroom – Buying Guide

Toilets usually come with similar basic features but when it to your bathroom’s limited space, you need to be more watchful in your choice of the best round toilet for a small bathroom. In this buying guide, we have a detailed description of all that you need to consider when choosing a round-front toilet for your small-sized toilet.


Since you are looking for a toilet for your small-sized bathroom, the size of the toilet you choose is critical. The size of the toilet will dedicate whether you save more space or less. While the width and height won’t be much of a bother, its length will be a determining factor.

The length from the front to the back of the toilet is what will help you save space. Shaving off a few inches to save more space in your bathroom is what you are looking for, right? As such, go for models that are compact within the range of 26 inches or less length-wise. We have plenty of them in this review.

Type of the Toilet You Need

Ideally, there are two types of toilets manufactured. There is a two-piece toilet, which is the most common type. The two-piece toilet features a separate tank and bowl and should any of the parts require replacing, you can simply replace one minus touching the other.

The one-piece toilet features the bowl and tank fused together. This design is beneficial as it is easy to clean with no visible seams harboring any grime or dust. Besides, when the one-piece toilet comes with a round front bowl shape, it becomes a deal breaker in saving you space in your small bathroom. However, you have to contend with the high price that a one-piece toilet comes with compared to the two-piece toilets.


When it comes to material construction, the choice is mostly between porcelain and vitreous china for the bowl. Porcelain is a durable and reliable material for a toilet and is overall cheap for the manufacturer. Besides, it is water-proof, easy to clean, and sturdy enough to support even the heaviest uses without a hassle.

Vitreous china on the other hand is a glazing technology that is added to porcelain to make it denser and shinier. As such, vitreous china toilets are even more durable and sturdy enough to last many years in your toilet.

Water Consumption

Toilet water usage varies quite a bit. Most of the older toilets can use up to 3 to 7 gallons of water in every flush. However, the newer models are highly efficient and can use up to 1.28 gallons per flush. Most of the models in this review use this amount of water. With this amount, you can greatly conserve water in your home.

Flush Type

There are a few different types of flushing systems you can find in round toilets. Some of the popular flushed include the gravity flush system which uses water to create flushing pressure. The pressure, in turn, forces all the contents from the tank, to the bowl and down to the trapway. A siphonic action completes the flushing process and cleans the bowl.

In modern toilets, you may find flushing systems like pressure-assisted systems that require the help of pressurized air to force water down the flush valve. This system gets water down faster compared to gravity systems but you have to put up with the louder noise as a result. A dual flush system is said to be economical with water as it gives you the choice to either use a partial flush or a full flush.

Installation Process

Even compact one-piece round toilets for small bathrooms are heavier to move around. However, their installation process is quite easier. This is because there is no hassle in connecting the tank to the bowl. So, once you get the toilet into position, the installation is just done, all you need is to screw in the bolts.

On the other hand, a two-piece toilet is equally easier since you can deal with the tank and bowl separately. This way, you split the overall weight between the two parts. In fact, even a single person can easily handle the installation since you don’t have to wrestle with more weight.

However, you must be very precise when mounting the tank onto the bowl to avoid leaks when flushing. Alternatively, you can hire a professional plumber to install if you are not sure about your DIY skills.


Like we mentioned above, pressure-assisted flushing systems are efficient owing to their high power. However, they produce a lot of noise in the process. So, if you want something a bit quieter, you can choose models with gravity flushing systems.

Another source of noise can be the slamming of the toilet lid. If this noise annoys you, look for models that come with Softclose seats that are designed to close gradually.


Reputable toilet brands offer warranties ranging from one year to a lifetime. The warranty can either be a manufacturer’s, a limited warranty on mechanical parts, a limited warranty on chinaware, or a guarantee period for a flushing system, toilet seat, and accessories. Therefore, whenever you buy your best round toilet for a small bathroom, make sure to look for a warranty.
