One Piece vs Two Piece Toilet – Which one is better?

One Piece vs Two Piece Toilet – Which one is better?

In the realm of washrooms, there’s a typical comparison that if the one-piece toilet is better for you or a two-piece toilet. Though both of them have their own advantages here we will explore everything about these toilets and will help you find out which one will suit you the most.

The comparison between them is exactly similar to squabbling over Batman versus Superman.

During my expert vocation, I’ve seen endless handymen thus called “specialists” slamming on two-piece toilets and adulating the one-piece toilet. In fact, one-piece toilets do enjoy a few benefits; however, does it genuinely win over the two-piece toilet?

Let’s find the answer to this question:

Essential Information:

Basically, there are three parts of every toilet:

Bowl – this bowl is intended to receive all the waste material

Platform – it is basically the part that helps to hold the bowl of the toilet in place

Tank – The holder at the back that stores water and releases it for flushing

What is One-Piece Toilet?

If the toilet and tank are combined with no joints, then the toilet is known as a one-piece toilet – otherwise called a single-piece toilet.

What is a Two-Piece Toilet?

If the toilet and tank are isolated and joined utilizing fittings, it is known as a two-piece toilet – otherwise called a dual toilet.

Indeed, the cost is essential and a critical factor, particularly when you can save an additional one to 200 dollars for a quality item or an imperfect item.

Single-piece toilets are by and large more costly than two-piece toilets because of the creative interaction.

To lay it out plainly, a one-piece toilet is made of a few little pieces. Terminating and gathering every one of the components into one takes expertise. Until the makers can begin utilizing 3D printers for assembling, all things considered, we will see one-piece toilets being higher in cost.

Delivery Cost

This is another significant factor. One-piece toilets are heavier and more hard to move, along these lines making them more costly to deliver.

Two-piece toilets are lighter and can be delivered effortlessly because the tank and the bowl are separate and can be sent independently.

Size Difference

There is an incredible misjudging in that the elements of single-piece toilets are more modest than two-piece toilets. This is a result of the one-piece not having any different parts, so will be more compacted into one unit.

At times, single-piece toilets have an alternate plan. Take TOTO 500 or Sanicompact for instance. In any case, in case we are discussing standard one-piece and two-piece toilets, there won’t be an enormous distinction with regards to estimate.


Standard one-piece toilets weigh around 40 kg (88 pounds), while two-piece toilet weighs around 25 kg (55 pounds). This is on the grounds that the one-piece toilet holds the clay tank during the terminating cycle underway, so the weight without doubt increments.


Difference between One-piece and Two-piece toilets - Usefulness

Other than the plan of the two toilet types, does the user find any distinction?

No, not under any condition.

As the adage goes, “It’s what’s inside that matters the most.”

At the point when we are discussing usefulness, we are alluding to the force of the flush, and hence, we are discussing the flushing system.

The amazing part is. In case you are not currently heedful, toilets are intended for that one capacity: to flush away human waste!


What about the sturdiness? The outcome is the same as the flushing power – Nothing.

Obviously, various producers have distinctive quality, yet extensively talking, there is certifiably not a colossal hole as to quality between these two models. Goodness, and just to remind you, because of the two-piece plan, they some of the time endures breaks among tank and bowl, yet this just occurs on the uncommon events.


Without a doubt, the one-piece toilet wins this round by a perfect KO.

Albeit one-piece toilets are weighty to move around, the establishment interaction is a lot simpler contrasted with the two-piece toilet in light of the fact that there is no problem of interfacing the tank and the bowl.

Then again, (get it? Since the one-piece toilet commonly needs a second pair of hands… ) when you are introducing the two-piece toilet, you must be mindful so as not to break the porcelain while connecting the bowl and the tank.

More often than not, the two-piece toilet doesn’t accompany a wax ring and a toilet seat.

Likewise, somebody piece toilets can be divider mounted, which is an extraordinary way of saving space in a little restroom.

Cleaning and Maintaining

Difference between One-piece and Two-piece toilets - Cleaning and Maintaining

The one-piece toilet wins this round. Why?

The explanation is a one-piece toilet doesn’t have a hole between the tank and the bowl, which can be practically inaccessible and subsequently develop microbes and microorganisms.

The two sorts of toilets are similar as far as administration life and usefulness.

Upkeep savvy, there are two angles to this inquiry:

  • Short term
  • Long term

Short term: The joint between the tank and the bowl of a two-piece toilet may wear off.

Long Term: It’s more reasonable to discover new parts for the two-piece toilet, on the grounds that each part is sold independently, which implies you can supplant the tank or the bowl exclusively. Nonetheless, if the one-piece toilet breaks, you need to supplant the entire unit.

Which one would it be advisable for me to pick?

One-piece toilet:

  • Simplicity of cleaning
  • Simplicity of establishment
  • More modest – rely upon the model
  • Mounting choice
  • Might be more minimal in stature
  • More sturdy, less inclined to break or hole
  • Bound to sit at solace stature
  • Flushing and water-saving choices
  • Weighty
  • More costly
  • Hard to transport



Two-piece toilet:

  • Less expensive
  • Lower transporting cost
  • Simplicity of moving
  • Simpler to move pieces to install
  • Flushing and water-saving choices
  • Blend and match tank and bowl
  • More choices for tallness, style, and color
  • Harder to clean
  • Bound to break and hole
  • Additional tedious establishment
  • Might be taller or less minimal
