Definition of one-piece and two-piece toilets

Before you decide which type of toilet is right for you, it is important to understand the definition of one-piece and two-piece toilets. A one-piece toilet is a single unit comprising the bowl, tank, lid and seat. This means no extra pieces for assembly are needed; it’s a single unit that can be installed quickly.

A two-piece toilet comprises two pieces: the bowl and tank. These two sections must be attached separately when installed, which takes longer compared to a one-piece model with its already preassembled components.

Now that you understand the basic definitions of both these types of toilets, let’s explore various features related to each toilet design in greater depth so that you can make an informed purchase decision.

Importance of choosing the right type of toilet

It is important to take your time when choosing between one-piece and two-piece toilets because the type of toilet you choose can affect the overall cost and efficiency of your bathroom. The type of toilet you choose can also make a big difference in terms of comfort and convenience. One-piece toilets are generally considered to be more efficient because they tend to be easier to clean, while two-piece toilets may provide more comfort due to their larger size.

While one-piece toilets may be a popular choice for many people, two-piece models offer some key advantages that one-piece models cannot. The main benefit is the larger water tank capacity, which can lead to better flushing performance and longer periods between flushing cycles. The bowl shape of two-piece models also fits more comfortably around the contours of most bathrooms, making them more suitable for older homes or bathrooms with limited floor space. They are also slightly easier to install due to their split design, which allows them to fit into tight spaces without too much fuss.

Comparison of One-Piece and Two-Piece Toilets

Before you choose between a one-piece and two-piece toilet, it’s important to understand the similarities and differences between the two. In general, one-piece toilets are more expensive than two-piece toilets, but they are usually much easier to install and maintain. Let’s take a closer look at the individual features of these two types of toilets.

Design: One-piece toilets combine an integrated tank and bowl into one seamless unit, simplifying installation and saving space. Two piece toilets, as the name implies, consist of two independent units: a tank that attaches to an integral bowl with a set of fasteners.

Installation: If you have limited space or are looking for faster installation times, one-piece toilets are usually recommended since they will fit through most doorways. On the other hand, two piece models may require more effort in order to make all the necessary connections like water supply lines or floor drain pipes.

Durability: Traditionally, two-piece toilets were stronger than their single model counterparts due to their bolted assembly but modern one piece designs have improved greatly in this area over time. As such both types can last upwards of 25 years with proper care depending on model type so lasting durability is not typically a factor when weighing cost/convenience differences between each style.

Maintaining: Generally speaking single units require less frequent maintenance than two piece designs because their seamless design makes them easier to clean – there is no gap or crevice where dirt and grime can accumulate like with traditional models that feature awkward corners and tight spaces near the bolts connecting tank and bowl components together.

Clearing obstruction — If either your one piece or traditional unit becomes clogged you’ll need access to your toilet’s inner workings which may be more difficult for larger single designs if it requires removal from your bathroom due its large size compared against two pieces that can be deconstructed easily during repair/maintenance visits from plumbing professionals.


When comparing one piece vs two piece toilets, the first point of discussion is design. One-piece toilets feature a seamless, monoblock design—which means the entire unit is molded out of one solid piece of porcelain. This eliminates the chances of additional leaks due to building integrity issues between pieces. It provides strong support, improved sanitation, and easier cleaning capabilities due to fewer crevices and angles.

On the other hand, two-piece toilets are constructed from two separate components that are installed separately. While they do require assembly on site and can potentially lead to small leaks due to inferior construction, they offer a more conventional look with an easier installation process due to its flexibility with different drainline configurations. This allows them to fit into smaller bathrooms or even remodeled areas where space may be limited. Additionally, two-piece toilets tend to be more affordable than their one-piece counterparts.

One-piece toilet design

One-piece toilets combine the tank and the bowl in one unified design, resulting in a striking, minimalistic look. As no nut or bolt is required for assembly, these toilets are very easy to clean thanks to their smooth and seamless surfaces. Thus, limited spots for dirt accumulation increase their durability.

Also referred to as ‘skirted’ design, these toilets do not require any additional parts and bolts for installation. Besides the elegant look, one-piece toilet comes with a powerful flush more often than two-piece designs. They save you time when it comes to cleaning as there are less nooks and crannys to address during bathroom cleaning sessions.

On the downside, they cost more than two-piece models.

Two-piece toilet design

Two-piece toilets are the most common type of toilet available on the market today. This design is constructed from two separate pieces, the tank and the bowl, held together with bolts. Generally, these types of toilets are less expensive than one-piece models and provide more shape options as they can be outfitted with round or elongated bowls. The traditional look of a two-piece toilet looks great in almost any bathroom décor due to their classic detailing and timeless style.

They also tend to be easier to install than one piece toilets because they come in two pieces that can be placed separately in your space and then connected with the flush valve hardware. Another great benefit of this design is that it allows for easy access for maintenance purposes when issues arise in the future.

It is important to keep in mind that a two-piece toilet design is slightly more difficult to clean given its intricate structure.


Price is an important factor when it comes to choosing the right toilet. One piece toilets cost, on average, between $125-$600 while two pieces toilets tend to cost between $100 to $500. The price difference is quite slight so you should make your decision based on other factors such as space, design and overall functionality.

One piece toilets can generally be more expensive due to the convenience of having one single seamless piece – often with a curved bowl for deeper cleaning that uses less water. They also can have a more contemporary look which can sometimes affect the price.

Two piece toilets are usually packed in pieces and require installation – although some come as a single unit already assembled from factory. They have a distinctive design and offer more flexibility in terms of placement due to separate tank and bowl pieces which tend to be smaller than a single unit toilet.

One-piece toilet price range

One-piece toilets are generally more expensive than their two-piece counterparts, with prices ranging from $200 to $1,500. One-piece toilets typically cost around 10% to 20% more than two-piece toilets. This is mainly due to the fact that these toilets require a large amount of labor and materials for construction. One-pieces also have fewer crevices than two-pieces, making them easier to clean when compared with two-pieces.

Although one piece toilets are typically the more expensive option upfront, they can often save money in the long run because they are easier to clean and less prone to leaks and other maintenance problems. If cost is a primary factor in your toilet selection, it may be beneficial to compare models within your desired price range before making a decision. With a little research and careful comparison shopping, it’s possible to find great deals on quality one piece toilets without sacrificing form or function!

Two-piece toilet price range

When shopping for a two-piece toilet, you’ll find there is a vast price range and some features that may influence your choice. Most two-piece toilets start at around $150 and go up from there. You may want to factor in the cost of necessary installation when assessing overall price. Basic models typically range up to around $250, while models that offer more advanced features – like low-flush technology or efficient water temperature – can cost anywhere between $400-$600 or more.

While the basic model of a two-piece toilet is most likely the cheapest option in terms of upfront costs, homeowners should consider the long term implications when deciding on which toilet is right for them. Depending on a home’s water usage and desired performance, it may be worth investing in a higher priced model that offers better efficiency or improved flush performance thanks to greater tank volume or lower water levels.

Overall, it’s important to note that regardless of whether you decide to invest in a basic model or an advanced one, all toilets need regular maintenance and upkeep regardless of price. Furthermore, there are options for every budget so be sure to compare prices before purchase!

 Factors to Consider When Choosing Between One-Piece and Two-Piece Toilets

When deciding between one-piece and two-piece toilets there are several different factors to consider. Each type of toilet offers distinctive benefits, such as improved installation time or enhanced motion capabilities, that can help you make an informed decision about which type of toilet is the best fit for your bathroom space. Here are some important items to review when determining what style of toilet is the most suitable for your home:

-Price: One-piece toilets typically come with a higher price tag than two-piece toilets. Consider your budget and decide whether you’re willing to pay a bit more for the convenience factor that one-piece models offer.

-Size: Determine how much space you have in your bathroom before settling on a particular model. One-piece models tend to be longer and can extend past into doorways or other areas around them while two-pice models tend to be shorter in length.

-Weight: One piece toilets are heavier than their two piece counterparts because they effectively contain all components in one unit rather than split into two separate pieces, which can make installation more difficult in certain scenarios.

-Maintenance: Two piece toilets tend to be easier and less expensive when it comes to performing maintenance and repairs since it requires access from the top or sides rather than having to uninstall completely from the ground up with one unit pieces like with one piece units.

These considerations should help you determine what type of toilet is the ideal choice for your bathroomspace but ultimately, either selection could be beneficial depending on personal preference. Installers can help evaluate any unique factors or issues that may need special attention during installation grants making sure each homeowner receives maximum value from their purchase decision.

Size and Space

A one-piece toilet is a single unit that combines the tank and bowl in one piece, while a two-piece toilet has a separate tank and bowl. The size and shape of each will be determined by the manufacturer, and these sizes may vary from model to model.

The size of the space where you plan to install your toilet will help determine which type you decide upon. One-piece toilets are often narrower than two-piece models, making them a popular choice in compact bathrooms where space is at a premium. They can also be shorter in times when standard floor heights don’t match up with the standard height of traditional toilets.

In contrast, two-piece toilets offer greater flexibility in where they can be placed due to their modular design — it’s easier to move around larger components like the tank and bowl separately versus trying to navigate a single unit through an awkward space.

Comfort and Ergonomics

The comfort of a toilet depends on its ergonomics, which is the design and structure of the toilet in relation to its user. Toilets with a round seat are usually more comfortable than elongated models, as they can make ample room for different sitting positions while also saving space. Two-piece toilets will generally have a round seat, while one-piece toilets may feature either elongated or round seats.

When it comes to ergonomics, one-piece toilets may provide better advantages for users who are looking for stable seating positions than two-piece models. This is because one-piece designs have fewer seams and edges, which can help reduce the chance of injury or discomfort from sharp or jagged edges or increased pressure points when sitting down and getting up. One-piece toilets also tend to be smoother since all components are built into one unit, making them easier to clean than two-piece models.

Additionally, many people prefer the look of a seamless one-piece toilet to the look of a two-piece model due to its sleek appearance and contemporary styling that can fit in almost any bathroom decor theme.


When it comes to one-piece vs two-piece toilets, there isn’t a right or wrong answer. Rather, the right choice depends on your own needs and preferences. One-piece toilets tend to occupy less space and give your bathroom a sleek and modern look. Meanwhile, two-piece toilets have an advantage in terms of affordability and the ability to separate each component for easy maintenance.

At the end of the day, pick whichever type fits your budget, lifestyle, and tastes best. No matter which you choose for your bathroom remodel, CP Plumbing Solutions can help you bring your visions to life quickly and professionally! Contact us today for all your toilet installation needs!
