One-piece vs Two-piece Toilet Bowl: What Is The Difference?

Homeowners who are planning to have a toilet bowl installation often have to pick between a one-piece toilet bowl or a two-piece toilet bowl. There are differences between these two. However, not a lot of people are aware of it to be able to decide which one is best suited for their home. Aside from this, homeowners are interested to know about the costs of these toilet bowls to help them make a budget-friendly choice. Below are the key distinctions between a one-piece and two-piece toilet bowl to help customers make the best choice.

The Tank and Bowl

The entire bowl of a one-piece toilet bowl is constructed from ceramic or porcelain. As the bowl and tank are connected during the moulding process, no additional connection is required to attach the bowl and tank. The reduced size of the one-piece toilet bowl makes the manufacturing process more challenging. In addition, it is designed to be a comfortable position for sitting. It is also easier to clean and maintain because there are no joints or gaps and it is a single item. In addition, P-trap toilet bowls are commonly used with one-piece toilet bowls to prevent gases from entering the home.

For two-piece toilet bowls, such as the Baron W-203A, the bowl and the tank that stores the flushing water are supplied separately to the house. The two components connect to the toilet bowl installation gaskets, nuts, and bolts. The connection between the tank part and the bowl is more challenging to reach. This bowl may also require repair or replacement, as its dual structure makes it prone to corrosion.

The Size, Weight, and Appearance

The dimensions of a one-piece toilet bowl are typically smaller because there is no space for connections. In addition to its sleek appearance, it is also one of the most preferred toilet bowls for small bathrooms. This is the primary reason for its popularity in homes with premium finishing. The TOTO CW823NJ 1-piece toilet bowl is one example. The distance between the toilet bowl drain pipe and the wall cannot be altered because the tank is already attached. The weight of a one-piece toilet bowl is typically more than a bowl that has two sections as the toilet bowl is constructed out of ceramic. This makes it hard to move around for installation, particularly in older flats, where there is only limited accessibility to lifts.

A two-piece toilet bowl such as the Saniton Camellia ST2488-SC3033IB-3 2-Piece toilet bowl consists of a tank and a bowl that are attached together. This is why it is larger in size compared to a one-piece. It also has a feature to adjust the space between the drainage pipe to the walls. It’s done by putting it in a tank with different dimensions or capacities. The overall weight of a two-piece toilet bowl is usually smaller since the tank could be constructed from plastic while the bowl is constructed from ceramic. This makes it easier to move the different parts of the bowl to any specific location. Most toilet bowls like Tiara 208 are made in two sections, which is why they are often found in older houses.

The Toilet and Installation Cost

Many of the popular toilet bowl manufacturers provide two-piece and one-piece options for the same toilet bowl. They want buyers to have the option to choose based on their preferences and budget. When we look at the toilet bowls of the most popular brands, we would find that the one-piece toilet bowl is more expensive than the two-piece bowl. In addition to this, toilet bowl size and measurements are two things you should know before buying a toilet bowl. Both of these have an impact on the installation cost, so it is also important to take those into consideration.

Although the cost of transporting one-piece toilet bowls to the home is generally more expensive, its installation is simpler since the bowl needs to be attached to the floor and the connection to the water supply needs to be constructed. It is less expensive to move the two parts of a two-piece bowl. The tank must be attached to the toilet bowl during the installation, and the connection must be checked. The additional connection and testing influence the cost of the toilet and the installation of the toilet bowl. Thus, increasing the time to install and costs for a 2-piece toilet bowl. 

Conclusion

The difference between a one-piece toilet bowl and a two-piece toilet bowl can be categorized into the following: parts, size, weight, appearance, and installation costs. The parts of these two types can be evident based on their names. The tank and bowl are connected in a one-piece toilet bowl; whereas these parts are separated in a two-piece toilet bowl. Understanding the advantages and disadvantages of one-piece toilet bowls gives you a more informed decision on its compatibility with your needs.

One-piece toilet bowls are generally smaller in size. However, because of it being a single unit, it is more challenging to transport it which adds up to the transportation cost. Hence, it is more expensive than a two-piece toilet bowl. On the other hand, the two-piece toilet bowl is easier to move around, making it less expensive to ship. Baron toilet bowls come in both one-piece toilet bowls and two-piece toilet bowls, so you may wonder why should you choose Baron toilet bowl to replace your old toilet bowl.
