What is a Compact Toilet?

Best Compact Toilet Compact toilets make the most out of the space of your bathroom. They typically have a more elongated shape than other toilets and may have a one-piece tank instead of two pieces. One-piece compact toilets are the smallest and have one singular construction making it easy to clean and the perfect size for any size bathroom. Even for a large bathroom, a compact toilet is a modern and stylish look that makes the most out of the space. Compact toilets are very efficient and because they don’t have a tank that holds water and uses a direct water source from the wall or floor so they generally use less water per flush.

Why Choose a Compact Toilet?

Compact toilets are perfect for a half-bathroom, guest bathroom, or for converting a space in your home into a bathroom such as an attic or garage. Compact toilets take up less space so they can be used in a smaller bathroom where a traditional toilet could not fit. For those with disabilities there may be a need for a toilet in an unconventional space, and the versatility of a compact toilets allows you to install them almost anywhere. Compact toilets are more energy and water efficient than traditional toilets so they will also save you money. They could cost less in up front costs as well as they use less materials.

Additionally, compact toilets sometimes come in an elongated design so they take up less space length-wise but are taller height-wise which makes it easier to sit down and stand up that with a compact toilet that is low to the ground. If you have a small bathroom where you would like to make the most out of the space, a compact toilet is right for you. A compact toilet may look awkward if used in a large bathroom, but they can be used in situations where you want to tuck a toilet into a space between a shower or sink. Compact toilets are ideal for small bathrooms and half-bathrooms in both homes and businesses.

How to Pick the Right Compact Toilet

Best Compact Toilet When shopping for the right compact toilet for you and your family it is easy to become bogged down with all the options out there. Today’s modern home appliance market allows for maximum customization of your home goods, so it is a good idea to look at the reviews for multiple products as well as handy buying guides such as this one to get a better idea of what features to expect and look for from the top selling compact toilets currently on the market.

  • Size

The size of the compact toilet is most important since they are typically sought after for use in spaces with unconventional size requirements. For a small bathroom, you will want to measure the space where the toilet will be installed to ensure the correct dimensions. You will want to accommodate for where your body will sit in relativity to the toilet and the wall as well as the space for the toilet itself. The height of the toilet is not important unless you have a shelf, cabinet, or pipe somewhere above where you are installing the toilet that may get in the way, in which case you will also need to confirm the maximum height requirements for your compact toilet.

    • Measure

If you already have an existing toilet that you are replacing the measurement process will be easier because you are simply determining if the new toilet will fit where the old one currently is. Start by measuring the wall behind the toilet to the center of the bolts in the middle of the toilet. This measurement is called the rough-in measurement and will be handy when you begin to look at toilets. For a small bathroom, you will need to measure the space surrounding the toilet in addition to the rough-in measurement.

    • Seat Height

The seat height is important because it can affect how easy it is to sit and stand up. Generally, adults prefer a higher seat height because it causes less strain on the back and knees to get up and down. Elderly and those with disabilities can have additional difficulty standing up and down and when the toilet is made in a compact design it could be shorter than a regular toilet so this is definitely a factor to consider when shopping for the right compact toilet for you and your family. An elongated toilet is made for compact spaces but has a tall seat height that makes it easier to sit down and stand up from.

  • Water Usage

Saving water is good for your bank account and for the environment. WaterSense works with the Environmental Protection Agency known as the EPA to promote water conservation in home appliances manufacturers goods and consumers. WaterSense labelled products have been tested and certified for water efficiency and are at least 20% more efficient than non WaterSense labelled products.

The water usage for the toilet is important not only for the environment at large, but it can also have an affect on your water bills over time. An inefficient toilet or a leaky toilet could be costing you hundreds of dollars in wasted water per year, and switching to a modern efficient model can help. Some toilets can use upwards of three gallons of water per flush, but all of the models in this guide are guaranteed to use less than half of that, making them some of the most water efficient toilets currently available in the market.

  • Flushing System

The flushing system determines how efficient the flushing is in terms of water usage and preventing clogs. It also may have an affect on the price both in the up front price as well as maintenance and parts over time. Flushing systems can vary from brand to brand, but typically use a syphon system of some sort to push and pull the water. It is important that the toilet also have an efficient backflow system to prevent any backwash. The flushing system also can have varying flushing power within the bowl in terms of how much water and from what direction the water flows. A toilet bowl with 360 degrees of water flow during flushing will be most powerful for cleaning. Additionally, some water bowls even use treated water systems that prevent buildup and staining.

  • Ease of Cleaning

One of the benefits of choosing a compact toilet is that they are often easier to clean than traditional toilets due to the minimization of cracks and creases where dirt and bacteria can hide. The material used is important as well. More porous materials will stain more easily, but when treated with the right finish will be highly resistant to discoloring. Having a one-piece toilet eliminates the crack in between the bowl and the tank that is usually a trap for particles and germs.

Some toilets have special treated surfaces for easier cleaning. In addition to the porcelain part of the bowl, the metal parts such as trip lever are also important when it comes to cleaning as shiny metals can show fingerprints and scratches easier than other metals. The inside of the bowl may also be treated with chemical activated water that can help to prevent the buildup of dirt and mildew.

  • Type

    • One-Piece or Two-Piece

One-piece toilets have a body that is tankless or that integrates the bowl and tank into one piece that is installed directly into the floor. A two-piece toilet is a traditional toilet that has a seperate bowl and tank. A two-piece toilet is generally larger than a one-piece toilet and does not make the most out of the space.

Best Compact Toilet Additionally, the two-piece toilet may create a space where bacteria and dirt can hide in between the two separate components. One-piece toilets are a more modern toilet solution that are perfect for a contemporary home.

One of the benefits of a two-piece toilet is that you could choose the tank and bowl separately to customize your toilet. With a one-piece toilet if something breaks you would have to replace the whole toilet whereas with a two-piece toilet you could replace the toilet bowl and tank separately. One piece toilets are also easier to install.

Pros of One-Piece Construction:

  • Easy to Install
  • Easy to clean.
  • Space-saving.

Cons of One-Piece Installation:

  • If one part breaks the whole thing needs to be replaced.
    • Tankless

Most one-piece toilets are tankless which means that they don’t use a tank. There are several benefits to a tankless design, one of them being that they are more space saving than traditional toilets. Tankless toilets use a syphon system to flush the water that is water conservartive and prevents clogs. Tankless toilets are sometimes more water efficient than other types of toilets because they don’t have a large tank full of water.

A tankless toilet doesn’t rely on a tank of water to flush the toilet, but instead uses a direct water line to use exactly the right amount of water to wash the tank. They make the most of the space and also save the most water compared to traditional toilets.


  • Save more water.
  • Save more space.
  • Can be more efficient.
    • Corner Model

Corner model toilets are made especially for closets, half-bathrooms, and super small spaces and can be installed directly into the corner so that they maximize the amount of space in the room. The tanks for a corner model toilet have a triangular base that can be installed directly into the corner. Corner toilets can be used in such spaces as a closet beneath the stairs to transfer any space into an extra bathroom.


  • Saves space.
  • For nontraditional bathrooms.
  • For super small bathrooms.
  • Fits into a corner.
    • Wall Mounted

Most toilets are mounted into the floor, but there are some benefits to a wall mounted toilet as well. Wall mounted toilets can conveniently make the most of spaces where floor mounting is not an option. The space saved by wall mounting a toilet makes wall mounted toilets a great choice for a small bathroom where you need a compact solution. Wall mounted toilets are common in public washrooms because they make the most out of space and are easy to clean.


  • Easy to clean.
  • Conserve water.
  • Small body makes the most of the space.
  • Elongated or Round Toilet Seat

Round toilet seats are the typical standard toilet seat that you see on most toilets. The round toilet seat is usually comfortable for most adults. The elongated toilet seat on the other hand is popular for elderly and is a great addition to a small bathroom because it makes the most of the space without being low to the ground which can make it accessible to those with back and knee problems. An elongated toilet seat is generally easier on the back and joints.

Elongated toilet seats are a more ovular shape and extend farther into the room that a round toilet seat. Many people find an elongated toilet seat to be more comfortable than a round one. Round toilets may fit well into a small space but an elongated toilet gives more room to sit and is more comfortable and can be used with a compact toilet to make the smaller toilet more comfortable.

  • Warranty

When shopping for any home appliance, especially one that is over $100 you should explore the warranty options that are available. Most reputable manufacturers will include some kind of limited factory warranty with the purchase that will protect your purchase from parts defects and shipping damages for a certain period after the purchase.

Most warranties expire between one and three years after the purchase and at best will guarantee excellent performance for the lifetime of the product. A good warranty may pay for itself time and time again in terms of parts repairs and replacement, so it is a good idea to contact the customer service department of the manufacturer to learn more about the warranty options that may be available.

  • What is the Difference Between One and Two-Piece Toilets?

Two-piece toilets are traditional toilets that have a seperate bowl and tank. The tank holds water that is pushed into the bowl to rinse it out. The tank then has to refill before the toilet can be flushed again. Two-piece toilets are less favorable for a few reasons. They are the traditional style so that is why some people prefer them, but the crack between them can allow dirt and bacteria to grow in the crevice. Another reason why some people prefer a two-piece toilet is because if the tank or bowl breaks the other part can be replaced instead of having to replace the whole thing as in the circumstance of a one-piece toilet breaking.

A one-piece toilet uses a direct water connection to pump water into the bowl, cleaning it efficiently. Because of this one-piece toilets use much less energy and water than other toilets since it doesn’t require a tank full of water to flush. One piece toilets are also easier to clean since they have less grooves where dirt and bacteria can hide. A one piece toilet is a more modern solution and can be found in many contemporary bathrooms both in homes and businesses.

  • Do Compact Toilets Function the Same Way as Regular Toilets Do?

A compact toilet may function differently than an elongated toilet because if they have a tankless design they will use a direct water supply instead. The benefit of this is that is generally uses less water per flush so it will save you money and be better for the environment. However, the actual function of the toilet will not differ much in what you will see versus what you may notice on your water bills. A compact toilet is simply a smaller toilet that doesn’t have a tank so it can more easily fit into a limited space.

The space needed for a compact toilet is less so you can put them into a half bathroom, a closet under the stairs, a garage, or another untraditional space. Compact toilets are more energy and water efficient which is another reason why some people prefer them over a regular toilet. Having a compact toilet that is high above the ground instead of low to the ground is typically better for those who have difficulty sitting and standing. While the function of a regular toilet and compact toilet are very similar, you should keep in mind that a very small toilet may look out of place in a very large bathroom.

  • Are Elongated Bowls Better Than Circular Ones?

Circular or round bowls are the traditional choice for toilet bowls but many people find that elongated bowls are more comfortable. A circular bowl may make the most out of the space however as an elongated bowl will extend several inches forwards. For a compact toilet, adding an elongated bowl may make the smaller toilet more comfortable.

Elongated bowls are often made with a shape that is optimized for cleaning as well. In addition, the flush may be more powerful as the shape and size of the bowl are optimized to flush away particles. Elongated bowls are typically considered the more modern and luxurious option over the traditional round bowl, and thus can be slightly more expensive. Round bowls are less comfortable for most people than an elongated bowl.
