Whether you’re remodeling your bathroom or simply want to replace an old toilet, buying the right kind of toilet is crucial for both your personal needs and bathroom plumbing. Before paying for a new toilet, you have to make sure that you check its design, features, and functionality first.

Also, you must keep in mind that buying expensive ones doesn’t automatically guarantee excellent performance. Instead, you should look at the big picture and consider buying not the best toilet ever, but the best toilet for your bathroom.

Before you decide, you must consider three different factors to ensure that you pick the toilet that is best suited for your needs.

1.   Toilet Design

The first thing you need to consider when buying a new toilet is how it would look like in your bathroom. With the wide range of toilet designs available in the market today, it can be difficult to choose only one.

To make sure you select the right fit, you must keep your bathroom interior design and theme in mind. Then, consider the available designs, such as two-piece, one-piece, and in-wall, as explained below:


Two-piece toilets are the most common ones you’ll find in hardware and home improvement stores. As you may already have guessed, these come in two pieces that are separate from each other: the tank and the bowl or seat.

In terms of advantages, two-piece toilets are usually the most affordable option in the market. Plus, they offer convenience and mobility because they can be carried separately. This makes it an excellent choice for bathrooms situated in the upper levels of a building or house.

But while these toilets are specially manufactured to fit together, there will always be a seam where the two parts are connected. And where there’s a seam, there will always be a chance of dirt and grime accumulation. Although it is often unseen by most people who use your toilet, its location makes it difficult to clean.


To solve the cleanliness issue with a two-piece toilet, manufacturers came up with the idea of a one-piece variant. As the name implies, this type of toilet has only one piece, which means there’s no seam, so it’s easy to clean. It is also very easy to install.

However, it can be slightly more expensive than the two-piece toilet and is difficult to carry around, especially upstairs.

In terms of aesthetics, this type of toilet can come with simplistic tanks or taller ones that look a lot like those included in the two-piece sets. Most one-piece toilets are suited for contemporary style bathrooms, but they can also fit traditional setups just fine, thanks to the abundance of designs to choose from.


As the name implies, this type of toilet has its bulky parts – the tank, specifically – hidden inside the walls. Of course, this isn’t always the case. Some in-wall toilets are tankless.

This type of toilet can help you save space, especially if you have a narrow or tiny bathroom. It is also best suited for sleek and modern bathrooms, as well as those with minimalist interior design.

However, you may need to ask for help from a plumbing expert during installation as it requires knowledge about your plumbing system. In some cases, you might also need to take down your wall first to ensure that your bathroom plumbing can accommodate this type of toilet. It can also be a bit more expensive than other toilet types, so be sure to check first before buying.

2.   Bowl Shape and Seat Height

Aside from the overall look of the toilet, the shape of the bowl and the seat height are two other crucial factors you must think about when shopping for a new toilet.

For instance, round bowls can help you maximize space in a bathroom, especially if it is a bit tight. However, elongated bowls offer more comfort and seating room that can be advantageous for some users.

If you want to enjoy the benefits of both, you can opt for compact elongated bowls that come in an elongated shape while maintaining the space-saving perks of a round bowl.

As for the seat height, most toilet bowls come in a 17-inch height, which is common in apartments and bathrooms made for public use. However, you can also opt for a toilet seat with the “comfort height,” which is set at 19 inches.

3.   Flushing Mechanism

Before choosing a toilet for your bathroom, you must also check its flushing mechanism. Generally, there are two main types of toilets according to flushing mechanisms: gravity-feed and pressure-assisted.

Gravity-feed toilets are more common in the market and maximize the law of gravity in flushing waste down the sewer. Pressure-assisted toilets, on the other hand, uses compressed air inside the tank to force waste down.

Aside from these, you can also choose between single- and dual-flush toilets. Single-flush toilets controlled by a single lever have more affordable upfront prices, but they may cost you more in terms of water consumption.

Dual-flush toilets, on the other hand, give you the option to use less water when flushing. They also come with buttons instead of a lever to separate the flushing options.

And then, there’s the touchless flushing toilet. This type of toilet requires no physical touch when flushing. You only need to wave your hand close to the sensor, and your toilet will start flushing.

The Takeaway

Like other bathroom fixtures, toilets come in a wide variety of shapes and sizes. Add that to the increasing number of features and flushing mechanisms, and you’ll probably spend a long time deciding which one to buy. To be sure, consult plumbing experts for advice on what is best suited for the specific kind of bathroom you have.
