10 Best Corner Toilets Reviews – Which One Should You Get?


We have reviewed our top 10 choices below and also done in-depth reviews by brands, but if you are in a rush:

Here’s our top choice: American Standard 216AD (Check Price on Amazon.com)


Corner toilets help you create a bathroom in a closet or a small space beneath your stairs as well as other smaller spaces around your home. The tanks on these models have a triangular shape that fits into the space where the two walls come together and a base that extends out from that space. Our list of the top models include those that come with a tank and base and those that let you mix and match components.

The 216AD from American Standard (Check Price on Amazon.com) is our top choice. It has the Cadet flushing system that the company designed to force more waste down per flush while still leaving your bowl clean and sparkling. It also comes with a triangular tank that is exclusive to American Standard and a power washing system that actually helps scrub the bowl to keep it cleaner.

How to Choose the Right One?

How Much Water Do You Want to Save?

The gallon per flush rating that a model has, also called the GPF, lists the total amount of water that the product uses when you flush it. These models come with a low rating of around 1.6 gallons and an ultra low rating that drops this figure down to under 1.3 gallons. Using an ultra low model will waste 16,000 gallons of water or more in a year when compared to older models that used more water.

Do You Need a Complete Set?

Most of the models we included on our list are complete models that come with both a tank and a bowl. As there aren’t many complete sets on the market though, we also include some separate components that you can buy. This lets you pick the right bowl and the right tank for your home.

Bowls can include elongated ones that are longer and thinner as well as round bowls that are almost completely round. Our list also includes one option that you mount on the wall, which gives you just as much floor space as any of these other models will.

How Often Do You Clean Your Bathroom?

No one looks forward to cleaning the bathroom, which is why many people put it off. If you want to spend less time cleaning the bowl, there are a few things to look for like one that comes with flat or smooth sides on the base. Bases that have decorative elements are harder to clean because those decorations attract more dust and dirt.

You can also look for those that come with a bowl that has holes along the rim, which produce more water that helps the bowl stay sanitary between cleanings. Some manufacturers make a specialty coating that is resistant to bathroom hazards like bacteria and mold too.

It even conceals the mounting hardware that comes in the box inside the bowl and uses plastic panels to help you access that hardware once it’s on the wall.

Depending on the layout of your bathroom, you may have the option of mounting this in a corner with or without some extra tools and supplies. The grip tight seat closes smoothly and silently against the rim and also leans back against the wall to give your back some extra support.KOHLER K-6299-0 Veil Wall

As its flapper is larger in size, that water comes down faster too.

Though this model only comes with a bowl, the round shape of that bowl takes up less space. You can use this vitreous china bowl as the base for use with a separate tank.American Standard 3717D001.020

Verdict: Our Top Pick

American Standard 216AD004.020

As we looked at the different corner models on the market, it didn’t take long before we found that the 216AD that American Standard makes is the top option. One feature we think you’ll really like is the power wash rim, which features more holes that allow more water to come out every time you flush, which allows the bowl to clean itself. Though this is a great feature for busy households, the product itself still uses only 1.6 gallons per flush to cut down on all the water that you usually waste.

The manufacturer chose vitreous china for this model because the material withstands daily use and won’t chip or crack as easily as other materials can. It comes with a base and a triangular tank, which is exclusive to products available from American Standard. This model also features the dependable Cadet flushing system that the manufacturer designed to remove liquid and solid waste from the bowl with one flush.
