What to Look out for When Buying a One Piece-Toilet

Best One Piece Toilets 2 Img

Flushing System

After reviewing different one-piece toilet brands, you will realize that there is a great difference in the flushing capabilities of various one-piece toilets across brands and models.

In order to find out how the toilet you intend to buy reacts during flushing, place some sponges in the bowl and see if it clogs. Moreover, make sure to review how the flush cleans the toilet bowl as well as how it carries the waste down the drain.

A great performing flush cleans the bowl effectively and leaves it unscratched. The flush also carries the material down the drainpipe without clogging the drainage system.

Water-Saving Features

Most people tend to believe that the more water they use in a flushing toilet, the cleaner it will be, but that isn’t always true. In most cases, toilets use almost 30 percent of water in a home, and this is quite a lot.

To minimize this wastage, toilets have been designed to use less water per flush. One piece toilets with an efficient flush system come with a WaterSense label.

As such, the toilet you intend to purchase should feature as low as 1.28 gallons of water per flush. This amount is sufficient to clean your toilet without clogging its drainpipes. As such, be keen when buying a water-saving toilet unit.

Size of the Toilet

When it comes to the toilet size, it is important to purchase a toilet that matches the current toilet rough-in measurements.

Additionally, you should look for a comfortable height that will ensure you and your family members can sit on and stand up from the toilet easily. The most preferable height is 19-inches plus or minus a couple of inches.


Your budget will also determine the price of the toilet you intend to buy. Indeed, you won’t want to buy a toilet that is way beyond your budget and neither will you settle on a cheap one. This means that everyone would like to settle for a fairly priced one-piece toilet.

It, therefore, is imperative to find a high-quality toilet that will last long as opposed to a bad quality one that will break and leak, thus costing you more in repairs.

Advantages and Disadvantages of One Piece Toilet


  • It is easy to clean since it comes with fewer crevasses and nooks
  • It is durable because there are fewer flushing elements and pipes exposed
  • It is easy to install since it comes with only a single piece
  • It is small-sized and can perfectly fit in small-sized bathrooms


  • It is a bit expensive with its solid construction
  • They are not ideal for adults or older persons

One Piece Vs Two Piece Toilet

When buying a one-piece toilet, you might want to weigh its benefits against those of a two-piece toilet. Both toilets serve the same purpose and come with almost the same flushing mechanism. Moreover, they are installed following the same method. However, it is wise to look at how they compare with each other.


A one-piece toilet is slightly smaller as compared to a two-piece toilet. This is because its tank comes fused with the bowl and sits lower than the two-piece toilet.

Owing to its smaller size, the one piece toilet is often ideal for installation in smaller bathrooms since they don’t need a large space. Moreover, its small size is ideal for use by small children and disabled individuals since its seat and handles are placed low.


The one-piece toilet features fewer gorges and nooks as compared to a two-piece model, and these make it easier to clean.

However, the fact that one piece toilets are low and close to the floor makes them difficult to repair because they might require uninstalling before repairing. Unlike the one piece toilet, the two-piece type is much easier to repair.


Owing to the fewer fittings in the one piece toilet type, maintenance is a bit easy. However, maintaining a two-piece toilet might be slightly difficult, especially in the tank and the joint areas.


Owing to the fact that one piece toilet comes in a solid piece of ceramic and with a concealed flushing system and pipes, it will last longer as compared to the two-piece toilet that has a separate water tank and an exposed flushing system.


In terms of prices, one-piece toilet types are often more expensive as compared to two piece types. This is because they are designed and constructed in a more solid way besides having a more modern look and feel.


Due to the fact that you will be handling a single piece, installing a one-piece toilet is relatively easier when compared to the two-piece type. Nonetheless, they are a bit bulky as compared to the two-piece toilets. As such, you might consider having more hands helping you when installing the toilet.

From this comparison, it is clear that the one-piece toilet is more advantageous in many aspects. Although its cost might be too high for some people, you will definitely get a more durable one-piece toilet.
