One Piece Vs Two Piece Toilet The Best Comparison

Comparing one piece vs two piece toilet isn’t worth the appearance. It is important to be aware of the three components of the new toilet, which comprise the tank, bowl, and pedestal. The tank holds water while the toilet bowl is the place where waste is disposed of to be taken to the sewer system. In the end, the pedestal determines the height of the toilet.

Once you are aware of the function of the fundamental parts and how they work, you can incorporate them into bathroom fixtures or designs for toilets. A single-piece toilet is a one-piece unit that does not have crevices or joints. However, the bowl and tank of the two-piece toilet are distinct.

One Piece Vs Two Piece Toilet The Best Comparison

Both toilets feature the same water-saving features and flushing power and mechanisms. There is a distinction between two-piece and one-piece models. This will allow you to decide the one you want to remodel or remove the old toilet and purchase new toilets.

Toilet Information Basic

As previously mentioned the toilet is the basic components, and they are as follows:

  • Bowl: The bowl’s function is to capture waste or pee that will be then disposed of in the sewer.
  • Tank: This serves as the reservoir for the water unit and it is operational when flushing is completed. Pressure is crucial to remove the waste.
  • Pedestal: It can also be used to refer to the toilet bowl’s holder because it lifts off the floor.

One-piece toilets – There is no joint connecting the tank and toilet since it’s a single whole or multi-part. A different term is a single piece toilet’. I’d like to recommend Swiss Madison’s SM-1T254 St. Tropez, EAGO TB351, Kohler 3810-0 Santa Rosa Comfort Height along with American Standard 2034314.021 as they are the top sellers.

The same manufacturer can produce the one- and two-piece toilets.

Differentialities In Construction

It’s simple to differentiate between two designs by their structure. A typical two-piece toilet comprises separate pieces: a tank as well as a bowl, whereas the one-piece toilet is made up of the tank and bowl in one piece.

It is easy to discern the difference by looking at the seam with the tank as well as the bowl. The seam is clear on the two-piece toilet however, there isn’t one for the single-piece toilet.

What Are The Benefits And Disadvantages Of These Two Designs?

The major benefit of the two-piece design is that it allows you to replace the bowl and tank separately. If the tank is damaged it is necessary to replace it as well as the toilet bowl.

Benefits And Disadvantages

If you break one piece of a one-piece toilet, you’ll need to replace the entire toilet. It is perhaps the only disadvantage of the one-piece toilet, apart from price. Since the tank is connected to the bowl, there’s no requirement for the tank to be supported.

This is where the area can be saved. It will also create a smaller, which is why the majority of toilets that are space-saving are constructed as one piece.

But, with siphonic toilets, it is possible to limit the length of the bowl. This is different from the washdown model.

In addition to looking beautiful Apart from looking great, the one-piece toilet is easy to maintain and clean. It’s the greatest benefit overall.

One-Piece Toilet

Pros
  • Great aesthetics. A perfect match for contemporary bathroom design in any modern house.
  • Simple to clean and maintain. Hygienic because there are no jointed parts that allow bacteria and dirt to be able to hide.
  • There is no worry about water spilling out of the tank, and flooding the floor.
  • More durable due to the absence of a joining component to maintain.
  • Smaller in size. A compact toilet is ideal to fit in small bathrooms.
Cons
  • It is not possible to replace the toilet tank or bowl on its own. If you damage any part from the ceramic, you must get to replace the entire toilet.
  • The toilet is bulky and heavy to install. However, once it is secured to the toilet flange the work is accomplished. In this way, it could be an advantage for some.
  • Price increase.

Two-Piece Toilet

Pros
  • The bowl and tank can be put together which makes it smaller and easier to move.
  • The toilet tank and the bowl can be changed separately.
  • Lower cost.
Cons
  • It is necessary to clean the region where the tank connects to the bowl. It’s hard to cleanse the area of joining without taking the tank off.
  • The joining area attracts dirt, grime, and bacteria.
  • The water will escape from tanks when a seal made of rubber begins to wear down.
  • Not as stylish as the single-piece model.

Size and Weight

One-piece and two-piece toilets are available in a variety of sizes. The majority of single-piece restrooms take up lesser space because of their design. The bowl and the tank are made of plastic to ensure that they don’t require more space, either from between the front and back or in the height.

But, the majority of single-piece toilets are built according to the comfort height guidelines Which is why the bowl will be at 17 inches instead of 15 inches. Two-piece toilets are available in the comfort and standard heights, and both toilets come in sizes that accommodate different bathroom styles.

one-piece toilet

If you are choosing a toilet the most important factor to consider will be the rough distance between the center of the drainage pipe and the walls that are behind the toilet. The majority of toilets are 12 inches, however, some come with a 10- or rough size of 14 inches. 

2-piece toilets come with many options to sit on a different size rough since the bowl’s size isn’t changed. You just need to order a different tank to be placed on top of the. 

One-piece toilets have the possibility of having the option of moving roughs to accommodate different bathroom sizes. If you’re dealing with roughs that are not the right size there are more options by using two-piece.

Toilets made of one piece are significantly heavier. This is due to the fact that the two-piece is able to be separated to move, which reduces its weight, whereas the one-piece is all contained inside one mold. Moving it may be more challenging, and shipping costs could be much higher.

Cleaning and Maintaining

The toilet with one piece wins this time. Why?

The reason is that a 1-piece toilet doesn’t have gaps between tank and bowl, which is nearly impossible to reach and therefore allows germs and bacteria to grow.

Both toilet types are similar in terms of their service life and performance.

In terms of maintenance There are two aspects to this concern:

  • Short term
  • Long term

Short for: Еhe joint between the tank and bowl of a toilet made of two pieces could wear away.

Long-term: It’s more affordable to locate parts that can be used to repair the toilet that is two pieces since each component is sold individually and you are able to replace the tank and the bowl in a single step. But, if the one-piece toilet is damaged, you’ll need to replace the entire unit.

Durability

One-piece toilets have an advantage in terms of durability. The connection between the tank and bowl in a two-piece model could be damaged with time. This means that the two parts could break off, requiring the replacement of either or both of them. In toilets that are very old, the rubber gasket that connects the two parts may wear away and cause leaks. This is a simple and affordable fix.

Durability

One-piece toilets are made of plastic and therefore have a lower risk of breaking the couplings. If there are cracks in the china tank in the bathroom, replacement of all of the toilets are needed. In the event that a china seat breaks in an asymmetric toilet, it is possible to replace the cracked part. Replacing the internal components of both toilets is similar, and the seat is able to be removed and replaced on any kind of toilet.

With the proper care, a toilet will last at least 50 years before needing replacement.

Installation – One-Piece vs. Two-Piece Toilet

The 1-piece toilet is difficult to install because of its weight and size. It can also be difficult in a tight space. Strong arms and a strong back can make for a simple installation; however, if you are not able to, getting help is not an alternative.

When you’ve got the toilet set it’s almost finished. The rest is simple, such as installing the plumbing, installing the seat, and sealing the seat. This is why the toilet made of one piece is easy to put in for those who have experienced DIYers.

One Piece Vs Two Piece Toilet

Two-piece toilets are more convenient to install in the sense that you can handle a bowl and tank. With less weight to contend with, usually just one person will be able to finish all the installation.

The trick is fitting the fragile porcelain tank on the bowl. Follow the manufacturer’s guidelines exactly to prevent leaks later. Cracks in the tank or the bowl could occur if you tighten too much the bolts.

A majority of the time the two-piece toilet doesn’t include a wax ring and a seat. The separate accessory is one more specification of the 2-piece toilets.

No matter if it’s a single-piece or two-piece toilet. Get expert help if you’re not sure about the job. The plumbing services will typically consist of removing your old toilet. That’s one less hassle than the possibility of doing it yourself.

Conclusion

In general, two-piece toilets are less expensive than their one-piece counterpart due to two reasons.

According to statistics, about 90% of toilets that are sold are two-piece models. The primary reason is that they’ve been in use for longer and the homeowners are familiar with the design. This is why they have economies of scale, which in turn reduces the cost of production. But the one-piece toilet wins in some aspects.

The one-piece toilet might not exactly have the same market share similar to the two-piece but its cost of production is greater by comparison. The more complicated manufacturing procedure of the 1-piece toilet is an element.

Yet, the one-piece design is affordable to the majority of customers. The cost ranges from $300 to $1000 for higher-end models.

One Piece vs Two Piece Toilet F.A.Q.

Is a 1 piece toilet better than a 2 piece?

One-piece toilets tend to be heavier and are easier to wash and have less room for bacteria to develop. Since two-piece toilets have tanks that can be detached and are more customizable to desired styles and sizes. Both designs can be equipped with bells and whistles such as bidets, or low-flow energy savings.

What is the advantage of a one-piece toilet?

One-piece toilets are generally larger and more difficult to wash as there’s less room for bacteria to develop. Because two-piece toilets come with an unattachable tank They’re also more adaptable to the most preferred designs and sizes.

What is the advantage of a two-piece toilet?

Size and weight: Because they are made up of two pieces, they can be transported in pairs. Toilets made of two pieces are less heavy than single units and are easier to move in a small space. Installing: Toilets made of two pieces possess certain advantages in terms of size and weight that positively impact the installation.
