corner toilets

Installing a corner toilet in your bathroom can make it more spacious and stylish. It is more difficult to install a waste pipe in a corner than in the wall.

A corner toilet is a great option for homeowners with small bathrooms who want to save money on renovations. You will need to measure your space before you buy a corner toilet. How do you decide which one is the best?

Here is my top choice of corner toilets with their pros and cons.

American Standard Cadet 3 Best Cornet Toilet

American Standard Cadet 3


American Standard 4338001.020 Cadet 3 Triangle 1.6 GPF Toilet Tank Only, White
  • Durable and easy to clean vitreous china construction
  • Ever Clean surface inhibits the growth of stain and odor-causing bacteria, mold and mildew on the surface
  • Oversized 3 inch flush valve with chemical resistant flapper
  • Flat tank cover for superior storage
  • Toilet tank only, bowl is sold separately

You might feel constrained when decorating a small bathroom. There is only so much you can accomplish! It can be cozy, but it doesn’t have to be boring. American Standard 216 is the perfect example. It is stylish and functional.

The siphon trap of all Cadet toilets has been widened to accommodate a wider siphon trap. It is now 2 inches wide and 1/8 inch taller. The 3-inch diameter of the flush valve has also been increased. These features allow the flush valve to push more load with less water while increasing its speed and power.

The toilet features power-scrubbing and bowl glazing. These features work together to reduce streaks and other toilet stains. The power-scrub function works by trapping air bubbles under the toilet rim at high pressure so when water pushes the bubbles, they ‘scrub’ the bowl.

American Standard 3717A001.020 Cadet 3 FloWise Tall Height Elongated Toilet Bowl Only, White
  • Compatible with Cadet 3 tanks, sold separately
  • PowerWash rim cleans the bowl with every flush
  • Toilet seat sold separately
  • EverClean surface inhibits growth of stain and odor causing mildew
  • Fully glazed 2-1/8 in. trapway helps to minimize clogging

The standard toilet height is 16.5 inches, without the seat. This seat must be purchased separately. The toilet has a sanitary dam that separates its bowl from its tank. This is the same as all American Standard two-piece toilets. Its trap contours can cause dust to collect on additional surfaces.

This toilet is a great option if you are looking for an easy-to-install toilet. This small tank is not a problem because the Cadet 3 Power Scrub system ensures that effective flushing takes place.

Pros & Cons

  • The trap measures 2.125 inches in diameter and the cadet system is 3 inches. This allows for increased flushing power It is EPA compliant at 1.6 GPF The compact size makes it ideal for a small bathroom
  • The seat can be purchased separately and the 1.6 GPF capacity is not compatible with water conservation regulations in Texas or California

Kohler Veil Wall-Hung Corner Toilet

  • One-piece wall-hung toilet

  • Includes wall-hung bowl with Grip Tight Reveal Q3 seat

Corner toilets are ideal for small spaces because they squeeze into the corner. This allows for more space for the user to move around and also for the door opening. You can also forgo the cistern if you don’t like the triangular tank. Tankless toilets can be a great solution.

You can place the Kohler toilet in any corner, or on the side. Be sure to choose the right wall, as it will block the door. The Kohler is a floating toilet, which means it doesn’t touch the ground. It is instead mounted on the wall.

The floating design creates an open area beneath the toilet that makes the bathroom seem larger and more spacious. The floating design creates an illusion of space, without increasing the size of the room. It has a skirted base, making it easier to clean. The elongated bowl of the toilet is also beautiful.

The dual flush toilet is 1.6 GPF for heavy flushes and 0.8 GPF for light flushes. The chrome push-button flush can be found on the wall just a few feet above your toilet bowl. This offers a comfortable flushing height and keeps the toilet surface cleaner because you don’t touch it with wet hands.

Many corner bathrooms can feel dark and cramped. The Kohler Veil toilet allows you to open up your space while also elevating your style. It also saves water.

Pros & Cons

  • The floating design keeps your bathroom cleaner because you can mop or vacuum the floor beneath the toilet. Unseen brackets made of stainless steel support the toilet. These brackets are strong enough to support the 53.5-pound toilet. You get an extra 12 inches of bathroom space because the toilet is mounted on the wall
  • They send you the bowl, lid, and flush plate as a single piece. It seems like everything is fine until you realize that it requires a tank and steel brackets in order to stay up. You can order them separately

Because their shapes fit into corners, they are called corner toilets. They are also smaller in-depth, which makes them less likely to block bathrooms doors. What if you purchase a right-angled toilet instead? A toilet where each surface has its own corner, not just the back.

You don’t need a triangular toilet tank. Square toilets are too complicated. What are your other options for your corner bathroom? The goal is to make your bathroom more spacious by compressing your toilet. How about hidden plumbing in a toilet?

Your toilet tank should take up approximately 12 to 15 inches. By hiding the cistern behind a wall, you can save space. Bathroom Anywhere offers three configuration options. Depending on your space needs, you can hide or leave everything. White one-piece toilet compact elongated bowl offers added comfort.

Ceramic Dual Flush from Renovator’s Supply

Renovator's Supply Ceramic Dual Flush Corner Toilet

It measures 30 inches from the corner to the rim. This is 3 inches less than the average corner toilet. It is resistant to stains and scratches so that it maintains its smooth sheen over time. Because of its texture trap, dust and droplets are attracted to it.

Before you go to the store, make sure that the bathroom door is open. Measure the distance between the open door and the corner to find the best toilet for you. The better, the shorter. The toilet at Renovator’s Supply measures 33.75 inches in depth from the corner to its rim.

The trap at the bottom is usually 2 inches in a toilet. The flush valve is usually 2 inches. If you need a stronger flush, a toilet should have a larger trap and a bigger flush valve. American Standard 270 AD features a Cadet 3 flushing mechanism.

For small bathrooms, round toilets are best. Although they are only 2 to 3 inches smaller than the elongated bowl it can make a big difference. You will feel much more comfortable sitting on the throne and it can help prevent your toilet door from hitting the seat.

Pros & Cons

  • To prevent staining, scratching, streaking, and streaking, Reno-Gloss is applied to the toilet. It’s a dual flush toilet that uses 0.8 GPF in liquid mode and 1.6 gallons per flush in solid mode. Its exquisitely carved details make it beautiful and unique to look at.
  • The trap is exposed so you will need to dust and wipe it often.

Signature Hardware Braeburn


small corner toilet

A one-piece is more durable than a two-piece in most cases. One-pieces are more durable than two-pieces because they don’t have seams or joints that dirt and dampness can hide. A two-piece toilet is more manageable if you are installing it in a corner toilet. It can be difficult to squeeze a one-piece in place during installation.

One-pieces are placed often flush against the wall making it difficult to clean around the bowl and trap. The signature has more floor space which makes it easier to maintain. You need to have access to the floor areas where dirt and water can fester.

The Signature toilet measures 16 inches high. It also comes with a slow-closing, padded seat. The 3-inch de-clogging flush valve is located on the right. It also has a convenient push-button flush. This flush lever is much more intuitive than the typical left-located ones.

The standard bolt spacing of this toilet is 5.5 inches. The chrome-coated flush button makes it easy to use. This toilet comes with a limited lifetime warranty as well as visible trap contours. The tank and bowl of a two-piece toilet are shipped separately, just like other toilets. They will likely arrive on different days.

The toilet is smaller than one would expect and it works well in small bathrooms. However, the toilet is less comfortable because of its smaller, rounder seat.

Pros & Cons

  • For easier access, the flush button can be found on your right. It has 1.28 GPF, so it is suitable for all US states. It allows for easy installation and maintenance from 360o
  • Toilet pieces are seldom delivered at the same time.


The Pros and Cons of Space-Saving Toilets

The corner toilet is placed in a corner, not in the middle of the bathroom. These toilets have a triangular-shaped tank. It can be tucked in the corner or as close as possible to the wall.

This will make a modern bathroom look larger if you have a smaller one. It doesn’t come with all the benefits. Let’s take a look at the pros and cons associated with space-saving corner toilets.

The Pros and Cons of Corner Toilets

  • They make the bathroom look more open.
  • Without having to tear down walls, you can make your bathroom more spacious.
  • It’s easy to add additional features like a tub or shower once a corner toilet has been installed.
  • It is now easier to add a bathroom in small, unused areas of your home.
  • They can use the same features as regular toilets, such as dual-flush systems and water-saving capabilities.

Con’s of Corner Toilets

  • Because of their tight location, the drain and incoming water supply can’t be installed as easily.
  • Because the toilet is below the plumbing, they are more difficult to reach if they have to be repaired.
  • This design isn’t as well-known as other toilet styles, so there aren’t many options.
  • Relocating the main drain is necessary for bathroom renovations. This means that you must tear down the floor.

What to Look for in a Corner Toilet

Corner toilets can come in many sizes, shapes, and styles. These and other features are explained in detail below. These features should be considered in order to choose the best corner toilet.


small bathroom

The toilet you buy should fit in your bathroom. For starters, take a look at the dimensions of a toilet. Corner toilets are compact and have been designed to save space, making it very difficult to go wrong.

To be sure that the toilet will fit into your bathroom, double-check its dimensions.

Water Use

When buying a toilet, water consumption is a key factor. This is a key indicator of the product’s quality and efficiency. Corner toilets are no different. A model that saves water and flushes waste efficiently is a must-have.

Even though 1.6 GPF is very efficient for water use, it’s still less than 4.6 GPF for older toilets. However, there are alternatives that use as little as 1.28 gallons per flush.

You can easily recognize them among the crowd because they have a WaterSense label. Although the difference in GPF between 1.28 GPF and 1.6 GPF may not seem like much, it’s a significant saving over the long term.

Flushing Mechanism for Corner Toilets

two piece construction

Water usage is affected by the flushing method. It is important to choose a flushing system that provides powerful flushing.

Select one that is able to move waste down the drain line, and clean the toilet bowl in one flush.

Dual flush is the solution. Dual flush not only cleans the toilet but also saves water.

Corner toilet bowl shape


You can choose from rounded or elongated bowls most of the time.

For those who want comfort, toilets with an elongated bowl are better suited to their needs. Rounder bowls have a lower profile and are more comfortable. For those who want something more, there are square bowls.

For ‘normal’ toilet purchases, you’ll focus on measuring seat size, from the seat bolts to the rim. This helps you confirm whether your toilet seat is elongated or round. Elongated seats work best because they’re more comfortable to sit on.

Measurement of the Rough-In for Corner Toilets

corner toilet

It is crucial to measure the toilet and then choose the correct size. The most popular options for residential homes are 10, 12, and 14.

Two measurements are required to measure the rough-in of your corner toilet.

Measure the distance between the plumbing and each wall. You should ensure that the distance between each wall and the plumbing is equal.

A professional plumber is a good option if you’re not confident about the rough-in. This will save you money in the long term.

Design & Look

corner toilets

Even though they are small, most corner toilets look great. They are made from durable and easy-to-clean materials. They are available in many different styles to meet your specific design needs and fit in any corner.

For added cleanliness, some models have a special finish such as EverClean or Reno-Gloss. These finishes have been proven to be stain- and bacteria-free.

Corner toilets can be made in one or two pieces. These toilets are ergonomically designed to reduce body strain.

How to Install a Corner Toilet

Make sure you read the entire manual before installing a corner toilet.

Pay attention to plumbing codes and building codes. We recommend that you get a professional plumber if you have any questions about how to install a corner toilet.

If you are looking to install the toilet by yourself, make sure to shut off the water supply lines where you’ll be installing your new corner toilet.

Before you start the installation, ensure that you have all the necessary tools. A tape measure, straightedge, level, pencil, and shim are all you will need. Also, caulk, saw, tile grout, and an adjustable wrench are also necessary.

  1. Measure the rough-in

    corner toilet

    To do so, measure the rough-in length out from the corner for every wall. As an example, let’s take a toilet with 12” rough in.
    Next, draw two parallel lines from the original marking. The location of your rough-in will be determined by where these lines intersect.

  2. Press the wax ring and secure the bolt down

    corner toilet

    The wax ring will go onto the toilet’s flange (located on the floor) with the flat side being down. To hold the ring in its place, apply a little pressure.
    Next, attach the anchor bolts to the flange. Point the bolts upwards. When the toilet is installed, the bolts should point upwards.

  3. Install the toilet and Secure in Place

    corner toilets

    After the wax ring has been placed, secure the bolts in place. Lift the toilet and align them with the anchor bolts.
    To secure the wax seal, place the toilet on its side and press down. You should not move the toilet again, as this could cause leaks and break the watertight seal.

  4. Add washers & nuts and tighten them

    small corenr toilet

    Add the washers and nuts on top of the anchor bolts. Check that the toilet is correctly aligned. Adjust if necessary.
    Finally, tighten the nuts and washers to the bolts. Don’t tighten your toilet too much, as this could cause cracks in the base.

  5. Insert the bolts into the mounting holes

    best corner toilets

    If you’re installing a two-piece bathroom, this should be done. Install a one-piece toilet by adding the washers and nuts on the tank bolts.
    Make sure the tank is completely flush. Then, tighten the nuts and washers until the tank is firm.

  6. add the bolt cap 

    best corten toilet

    Put down the bolt caps on each side of the toilet, over the anchor bolts.
    Use a saw to trim the bolts to the correct length if they are higher than the washers or nuts.

  7. Connect your water supply

    corner toilet

    This can be found towards the bottom of the tank. To check for leaks, turn on the water supply and flush the toilet several times.
    Continue to the next step if there are no leaks around either the back or base of the toilet.

  8. Add a toilet seat and caulk above the base of the toilet


    Place the toilet seat directly on the bowl, and attach it using the bolts provided in your installation kit
    To finish the installation, use latex caulk or tile grout to seal off the base of the toilet.
