Best Corner Toilets Reviewed

Find a top-rated corner toilet for your bathroom space requirements in this detailed review.

by Caitlin Shaffer

Utilizing every space in your home is essential if you have a growing family or are looking to renovate a space to add a bathroom or bedroom.

Working with a room larger than a closet is easy, but don't shy away from adding that powder room or half bath in the closet under the stairs. Corner toilets have made this possible.

Why Buy a Corner Toilet?

If you're transforming a closet beneath the stairs into a small half bath or if you're renovating an existing bathroom but desire more space, corner toilets are perfect solutions to your problems.

With a triangle prism tank shape, corner toilets are designed to utilize the 90-degree spaces of a small room. You can easily tuck one of these into the corner and use the rest of the area for your sink, vanity, and décor.

Some of the pros of installing a corner toilet include:

  • Saving space
  • They use the same plumbing and flushing technology as standard toilets
  • Make a rare style statement
  • ADA compliant

However, there are still some drawbacks, including:

  • Initial cost
  • Not many complete set options
  • Some models have hard to operate handles because of the angle

Corner Toilet Buying Guide

Sizing

When shopping for the best corner toilet for your home remodel, consider the dimensions of the tank and the measurements of the wall. Make sure these numbers match so you can have a toilet tank the sits flush against the wall. Make sure you have roughly 15 inches of space between the corner and the bottom of the base and that the bowl sits more than 24 inches away from any sanitary spaces such as sinks and showers.

Design Features

Corner toilets come in a variety of colors, shapes, designs, and flushing mechanisms. Find out what suits your needs, both aesthetically and functionally, in order to get the toilet that's right for your space. Some toilets come in a one or two pieces, so you should take this into consideration when trying to install one by yourself.

Seat Height

Is your toilet going in a child's bathroom, or the attached apartment for your elderly parents? Take their needs into consideration and stick to toilet models that are ADA compliant or are comfortable to sit on for the youngsters. Some models even make it easier for seniors to sit down and get up.

Bowl Type

Elongated toilet bowls are more comfortable to sit on, but round bowls don't extend into the room as far. When you consider the space of your small bathroom, consider the bowl type. Round bowls tend to be fit into these smaller bathrooms more easily, but if you're looking for a bowl that's easier to clean, go with an elongated unit.

Water Saving Features

Saving water is essential when shopping for a corner toilet. When looking at water consumption, stick to models that lie in the range of 0.9 to 1.6 gallons per flush. If the GPF is within this range, you’re likely to save money and water. Some models even come with dual flushing options, dedicated to saving water based on the waste that’s flushed.

Flushing Mechanism

Dual flush mechanisms give you a flushing option for urine or pure liquids, with the other option being designated to help flush down solid waste. This allows you to save money on water when each flush used efficiently. With single flush toilets, one handle or button is used for all types of waste.

Ease of Use, Installation & Maintenance

Corner toilets are rather easy to use but could require more guidance for installation. Consult with the owner’s manual or your local plumber when putting one of these models into a new bathroom. Cleaning and maintenance should also be considered when comparing models.

Price & Warranty

Corner toilets meet a variety of price points with different warranties. Consider your budget needs and what kind of warranty you're after when shopping for the right unit. Always consult the manufacturers' guides and the benefits that come with each warranty to understand which options are right for you.

Corner Toilet vs. Regular Toilet Comparison

Both corner toilets and regular toilets have their perks, but nothing can beat the space you save when you install a corner toilet. Not only do they look different and add a modern twist to your bathroom, but they also save you plenty of water and energy with every flush.

On the other side, there are plenty of standard toilets on the market that save you water and energy as well, and many come in a variety of different styles and colors.

If you have the room for a standard unit and want something more custom, find a way to get a standard toilet, but if you need the space and want a bathroom that looks and feels open, go with a corner toilet.

How to Install a Corner Toilet

Installing a corner toilet depends on the state of your current bathroom and how much remodeling you're doing in order to install a corner toilet.

Often, the location of the current rough-in for a traditional toilet may not be near the corner of the room, and you'll need to extend the plumbing and to create a new rough-in. In this case, it's always best to consult with your local plumber to help get the plumbing moved and the new toilet installed.

However, if you’re simply replacing a current corner toilet, you just need to make sure the dimensions of the corner and the rough-in are the same and pick out your new toilet. If you need additional help, check out these online tutorials for installing a corner toilet.

Corner Toilet Cleaning & Maintenance

Cleaning a corner toilet is similar to how you’d clean a standard unit. There really isn’t much difference between how you’d clean the two toilets, except that you may be able to reach around the back of the base a little easier with a corner one.

However, there is a difference in cleaning a round bowl versus an elongated one. Round toilet bowls can be a bit more difficult to clean since they tend to have a deeper lip on the inside. It’s best to invest in a good cleaning brush that can reach up into this crevasse of the toilet.

Clean your corner toilet as you would any other bathroom, and you’ll be just fine. If you’re looking for more tips on bathroom cleaning, you can find plenty of resources online.


People also Ask (FAQs)

What does corner toilet short projection mean?

Corner short projection means that the depth of the toilet has been reduced to be accommodating to a smaller bathroom. These types of toilets will not protrude too far into your walking space and typically take up less floor space than other units.

What is the difference between a 10 and 12 rough in toilet?

A rough-in refers to the distance from the wall to the center of the toilet waste outlet or floor drain. The standard measurement for both a regular toilet and a corner toilet is 12 inches, but it's also not uncommon to see some with 10-inch or even 14-inch rough-ins.

Measure your existing rough-in, and that will tell you what type of toilet you can pursue.

How much space is needed for a corner toilet?

Not all bathrooms are the same, and it's not wise to just purchase a corner toilet and hope it fits. To find one that fits your bathroom, compare all of the measurements, and find one that matches. In most cases, you'll want to leave at least 15 inches of space between the unit and the wall or other fixtures, as well as have at least 24 inches of space in front of the toilet so you can get up and move around.

What are the best corner toilet brands?

Some of the best brands on the market include American Standard, RSM, Kohler, Eljer, and Toto. Which brand or style of toilet you go with is all up to your budget and what kind of features you’re looking for in a unit.

Can I change from a traditional toilet to a corner toilet without having to move the drain?

If you're not sure whether or not you can use the existing drainage for a new corner toilet, it's best to consult with your local plumber. Most standard toilets are not situated in a corner position, and you may need to adjust for this. Talk to your local professionals before you purchase a corner unit.

Where is the best place to find corner toilets for sale?

You can find some of the best deals for corner toilets on Amazon but also through your local Lowes or Home Depot. If you want to see a toilet in person, it's always best to visit your local retailer before buying online for the best deal.


Conclusion

At the end of the day, your bathroom remodels or renovations should result in a space that's easy to use and stylish. Corner toilets solve a space issue and can often become a focal point in a bathroom.

Our overall conclusion is that you’re going to love our no.1 pick: The American Standard 270BD0001.020 Cadet 3.
