One-Piece Toilet

One-piece toilet features an integrated tank and bowl. Because of this, they are easy to clean. Also, they eliminate the gap between the toilet tank and bowl that is a breeding ground for mold, bacteria, and other substances. Also, this makes the toilet compact as the tank is lower.

Pros:

  • Straightforward to clean
  • Well-built to last long
  • They are more compact to fit in tight spaces easily
  • Sleek and elegant design
  • Straightforward to install

Cons:

  • They are slightly expensive than two-piece units
  • Quite challenging to ship as the bowl and tank are integrated into a one-piece
  • They have fewer rough-in options

Two-Piece Toilet

Two-piece toilets come with a bowl and tank separately. As a result, the toilet is easy to ship, and you can maneuver or mix and match different bowls and tanks. Also, it is easy to maintain as spare parts are easy to find.

Features Comparison between 1 piece and 2 piece toilet

Durability

A toilet is not something that you select randomly. Since you will be using your toilet for many years to come, why not pick the best and most durable? When it comes to the battle of 1-piece VS 2-piece toilet in terms of durability, the one-piece toilet has an edge. This is because two-piece toilets come with a coupling between the tank and bowl. The coupling may crack after some time, and the rubber gasket found in this section may degrade and start to leak. With one-piece toilets, there is no coupling; hence, you won’t experience such challenges.

Space considerations

If you want to save space, then the one-piece toilet is the way to go. Since a one-piece toilet comes with the tank and bowl incorporated into one unit, it doesn’t take up much space. However, two-piece toilets come with lots of rough-in options when compared to one-piece toilets.

Even though a one-piece toilet comes in a single unit, it is not very convenient to ship. Two-piece toilets are simple to transport as they come in different pieces. Also, one-piece toilets are quite heavy, which is a disadvantage during shipping.

Appearance

Unfortunately, one-piece or two-piece toilet designs do not determine how beautiful the toilet is. With that said, one-piece toilets look more elegant with a modern appeal when compared to two-piece toilets. The good news is that some one-piece toilets feature a traditional design and some two-piece toilets a modern look. So, you won’t be limited to what type of toilet to choose.

Ease of installation

Two-piece toilets are quite challenging to install as you need to bolt the tank to the bowl. On the other hand, one-piece toilets don’t need this as the tank and bowl are integrated into a one-piece. But a two-piece toilet gives you the chance to move and maneuver as you install it. Always get some help when installing the one-piece toilet as they are quite heavy.

Maintenance

Today, many people are embracing one-piece toilets because they are straightforward to clean and maintain. One-piece toilets don’t feature a coupling, which is a breeding ground for mold, mildew, and bacteria. So, cleaning is made easy, and you don’t have to clean the tank and bowl-like with two-piece toilets continually.

Costs

Typically, one-piece toilets cost more than two-piece toilets. It doesn’t matter if they have the same features and even color, they will still cost more. This might be attributed to their durability, ease of cleaning, and overall aesthetics.

Final thoughts: One Piece or Two Piece Toilet?

All-in-all, there is no significant difference between a one-piece and two-piece toilet. It all depends on your taste. However, a one-piece toilet offers more comfort and is easier to maintain than a two-piece toilet. Also, they look more beautiful as they have the tank and bowl seamlessly integrated into a one-piece. The only challenge is that they are slightly costly than two-piece toilets.

Whichever toilet that you choose, you will still get the same comfort and performance as long as they share the same features. Still, have questions after reading this One piece VS Two Piece toilet comparison? Comment below.

  1. Two years ago, I had a Huberhaus 1 piece toilet at the cottage. In the fall, I drained it and poured RV antifreeze in the tank and flushed it. Then flushed it until only antifreeze remained in the bowl. It didn’t survive the winter. Temperatures in Ottawa Ontario, Canada can reach -40 -50 in winter. I have installed a similar one this summer because of its smaller footprint. Other than removing and storing it at home, is there a means of ensuring that it is completely drained. Would it be necessary to leave any antifreeze in the bowl? Your comments would be appreciated.
