Update On

Do you need to put a toilet in a tight space? A corner toilet may be the answer you are looking for. This type of toilet has a triangular tank that fits into the place where two walls meet. The bowl and seat sit in front of the tank, jutting into the space from the corner. Let’s look at what you should consider when selecting the best corner toilet and see which one may fit your needs.

How to Select the Best Corner Toilet

Corner toilets are not the most common commode on the market, so the selection is limited when compared to standard models. However, it’s important to purchase a toilet that fits your needs and that will last for a long time. Here are some key criteria to consider when selecting a corner commode.

Floor Space

A common reason for installing a corner toilet is to open up floor space in a tight bathroom. When selecting the toilet, make sure you know its dimensions, including how far the front edge of the bowl is from the corner. That’s going to tell you how much floor space the toilet will cover.

It’s also important to know the rough-in measurements of the toilet. The rough-in is where the floor drain sits in relation to the walls and corner. If the rough-in isn’t in the right place, you will either need a new toilet or have the plumber come in and replumb the drain.

A corner toilet’s rough-in measurement is done by measuring from both walls to the center of the drain pipe. So, a 12-inch rough-in means the center of the drain pipe sits 12 inches from both walls. If it’s off center, the toilet won’t fit.

Water Consumption

A consideration for any new toilet you buy is how much water it uses. Modern toilets sold in the US must use no more than 1.6 gallons per flush. To earn the WaterSense certification from the EPA, a toilet must use no more than 1.28 gallons per flush on average.

Some toilets offer dual flush. The partial flush, used for liquid waste removal, usually uses significantly less than the full flush, used for bulk waste removal. A few models of dual flush toilets have enough pressure in the partial flush to handle light bulk waste removal.

Flush Performance

Flush performance is key with any toilet. You don’t want to have to flush multiple times just to get the waste out of the bowl. Toilet manufacturers have improved their engineering in recent years, making commodes that can do the job with less water.

Another consideration in flush performance is whether the flush clears all traces of waste. While the flush may remove the waste, it should also clean the sides of the bowl at the same time. If the buyer needs to clean the bowl multiple times a week, the toilet isn’t doing its job properly.

Corner Toilet Design

Toilets can last for decades, so a commode’s appearance is important. Select a style that fits into the bathroom and into the home. Many commodes will work in both traditional and contemporary spaces.

Some, however, have a distinct style that only works in limited design spaces. A Victorian home, for example, calls for a more traditional style. A sleek, minimal unit would be a bit out of place in such a home.

Ease of Installation

Another consideration for selecting a corner toilet is how easy it is to install. Corner toilets install pretty much like any other toilet. The only real consideration is the placement of the drain during rough-in.

Some toilets have a full skirting that obscures the bolts used for installation. These designs can be a bit rougher to install, but not impossible. An experienced plumber or even a serious DIY’er should have no problems doing the work.

Ease of Cleaning and Sanitizing

Cleaning a toilet should be as simple as possible. A traditional toilet exposes the curves of the trapway along the base. These curves and details attract a lot of dust and dirt. A skirted design hides the trapway, making it much easier to clean.

Another consideration is the glazing in the bowl. Manufacturers have come up with special glazes that help keep the toilet bowl cleaner. They also help to prevent the growth of mold and bacteria. While a traditional glazing does its job, these special glazes make cleaning easy.

Seat Height

The top of a toilet rim on a standard toilet sits 14 to 16 inches above the floor. Add a toilet seat and you get seating between 15 and 17 inches. This is good for kids and shorter adults.

For taller adults and those with limited mobility, a comfort height toilet is often a better choice. These toilets, with seat installed, sit between 17 and 19 inches from the floor. The higher seat height makes sitting and standing less stressful.

If someone in the household uses a wheelchair, the height of the toilet seat should be near that of the wheelchair. It will make transferring much easier.


Price is a key consideration for those on a budget. You want a toilet that has the features you desire, but doesn’t cost too much. Plus, you need to consider the cost of maintenance and repairs.

Spending a bit extra up front may give you a more useful toilet that will do its job well for many years down the road. On the other hand, a basic toilet can last for decades. Those with special features may cost more to maintain in the long run.


A toilet is built to last for decades. However, not every toilet is perfect. You need a good manufacturers warranty to cover the commode in case something goes wrong. Most problems appear within a few months of use, but some don’t appear for years.

Where a Corner Toilet Is a Good Idea

Corner toilets are designed to fit into the space where two walls meet. This type of design is useful in some design scenarios.

  • Bathrooms and powder rooms with limited floor space
  • Retrofitting a bathroom under a staircase or in an existing closet
  • Spaces with an awkward layout where a standard toilet configuration wouldn’t work
  • Bathrooms in smaller homes
  • Adding a bathroom or powder room in the basement
