The pedestal means that the toilet has the optimal height. Although supplying the necessary flushing power to maintain the bowl clear, the tank stores a certain amount of water.

In addition to extracting the garbage, toilet bowl means that the waste makes its way through the drain pipeline.

When it comes to conventional one-piece toilets (also referred to as one piece toilets), the tank and bowl are glued together with no joints.

Two-piece toilets (also called coupled or double piece toilets) use the construction where the tank and bowl come separately; they may be joined with fittings.

One-Piece vs Two-Piece Toilets: Is there a performance difference?

Both toilet choices work well. The standard of efficiency is almost the same, and in their one-piece and two-piece versions, manufacturers provide the same or somewhat close designs. So, which toilet are you going to choose?

One-Piece vs Two-Piece Toilets: The Main Differences

We will detail the key distinctions between one- and two-piece toilets to help you choose the best toilet for your bathroom.

In regard to the deciding factors, such as presence, efficiency, installation, repair, price, and so on, the idea is to compare these two styles. Let’s dive in, then!

Functionality & Results

Essentially, there is no major gap in terms of functionality and efficiency between one-piece and two-piece toilets.

That’s because the quality and strength of each are nearly similar. The functionality of both toilets relies on the configuration of the toilet and the procedure for flushing.

Provided that much of the features and internal pieces are similar, this does not come as a surprise. This is particularly valid in the case of toilets from the same maker.

You will see these characteristics in both one-piece and two-piece toilets, whether you choose water-saving or comfort height. They both come with separate flushing technologies, from tower flushing to flapper flushing technology.

So, make sure to verify reliability and efficiency for each product, whether it is a single piece or a paired toilet.

Installation Ease

As far as the installation is concerned, both two-piece and one-piece toilets have their own advantages.

Although the installation is somewhat close with respect to complexity for both styles, installing a one-piece toilet requires less time.

You can have a tough time putting it in the proper place, though. It takes some practice and effort to manipulate and shift a one-piece toilet into place, particularly if you do it by yourself. So it is better if you want to build the toilet on your own to select a two-piece choice.

You’ll be holding two light and compact parts instead of pushing one bulky and large machine. This would make it easy for you to move the toilet and manipulate it.

Bear in mind that two-piece toilets require a second assembly method, since two pieces need to be bolted together. Aside from this, when installing the tank in a 2-piece toilet, you must be very vigilant in order not to crack the porcelain.

Cleaning Ease

With minimal work and low upkeep, you want to keep your toilet tidy.

That’s so more people choose a one-piece toilet over a two-piece restroom. As there are no holes or holes between the pipe and the reservoir, it’s simpler to vacuum.

Single piece toilets feature skirted bowl with the smooth and flat outer surface. The molded form with no grooves or nooks means fewer space to get stuck by dirt and grime. Around the same time, it inhibits the development and propagation of bacteria and mold.

All of this renders bathrooms of one piece even more hygienic and simpler to maintain. Two-piece toilets have more parts that are challenging to access, because they are more difficult to clean. The joint region is especially favorable for the collecting and growth of soil and germs.

Dimension & Weight

There are numerous styles for both two-piece and one-piece toilets and toilets.

Generally speaking, due to their design, single-piece versions take up less space. As the bowl and tank are shaped together, they do not take that much space.

Most 1-piece toilets have a comfort height, which means the bowl sits at 17″ (not at 15 inches).

On the other side, two-piece toilets are available to fit various bathrooms in both comfort and normal height.

Take the time to inspect the rough-in before buying a toilet. The gap to the middle of the waste outlet or the drain pipe from the completed wall behind the toilet applies to this calculation. Many bathrooms have a rough 12-inch, but versions sitting at 10 or 14 inches can also be identified.

There are further choices for rough double-piece toilets and they are uniquely sized to accommodate various bathrooms. You would be able to purchase a particular tank according to your preferences owing to the fact that the bowl capacity would not change.

Because it comes in one mold, single piece toilets appear to be heavier. You would have the option of uncoupling the toilet components with a two-piece toilet, thus reducing its weight. This would make transporting, holding, and pushing the toilet simpler for you.


As one wide piece of bathroom fixture, single piece toilets are made, so there is no joining component to manage.

It helps them more precise and stronger. Besides, you’re not going to have to think about a leak.

In the other side, the two-piece toilets need special caution, as the relation between the bowl and the tank can break over time. You’ll have to substitute either or even both sections at a time until these two components are uncoupled.

And not the only thing is this. In old two-piece toilets, the rubber gasket linking two parts begins to degrade after a few years. This may cause leaks.

Nevertheless, with good use and care, any form of toilet is worthy of lasting for several years. In reality, without having a replacement, they will both live more than 40 years.

Aesthetic Gaze

In a full variety of shapes and sizes, both 1- and 2-piece toilets come.

Although both are accessible in several pleasing styles, one-piece toilets are a definite favorite when it comes to cosmetic appearance.

This is one of the reasons so many people want a one-piece toilet.

What makes one-piece toilets look sleek is the consistent, smooth construction without a distance or joint between the body and tank.

In comparison, a skirted toilet bowl lets it seem sleek and contemporary. It will bring a glamorous look to your bathroom and a modern touch.


A cheaper alternative to go for is the two-piece toilet. Overall, and with the same design and maker, single-piece toilets cost less than their two-piece counterparts.

That’s because a larger amount of capital is needed for the streamlined design and requires a complicated manufacturing process.

In addition to higher manufacturing prices, owing to the fact that they are a little larger, one-piece toilets often come with greater shipping costs. So, go for two-piece toilets if you’re looking for a budget-friendly alternative.

Most two-piece toilets cost between $300 to $500, although for high-end versions, the price of one-piece toilets varies from $400 to more than $1000. Many consumers can obviously afford to purchase one-piece ones.
