If you have limited bathroom space, installing a corner toilet can save space and still make a statement in terms of style. Keep in mind, though, that installing a waste pipe in the corner versus the wall will be more difficult.

If you have the same problem, consider installing a corner toilet in your bathroom. It will make your tiny bathroom seem more spacious and free up unused space.

Corner toilets take up less space than traditional toilets, making them ideal for people who live in small homes. Also, such toilets work best for individuals who are looking for efficient ways to utilize every inch of their bathroom space.

These compact toilets are specifically designed to cater to specific design requirements with the use of the triangle-shaped tank. This shape makes the toilet fit into nearly any corner.

Before buying a corner toilet, you’ll have to measure the right dimensions for your space. Despite being smaller units, corner toilets can still offer advanced features like dual-flush and self-cleaning mechanisms.

Before Buying a Corner Toilet

Corner toilets come in different shapes, styles, sizes, as well as water consumption rates.

All of these features, among other things, are thoroughly explained below. They should be taken into account in order to find the best corner toilet.


The toilet you get to buy is supposed to fit nicely into the available space of your bathroom. So, check out the dimensions of a toilet for starters.

Luckily, corner toilets are compact and designed with space in mind, so it’s really hard to go wrong.

Yet, you should double-check the size to be certain that a toilet would fit in your own bathroom.

Water Usage

Water consumption is no doubt one of the key factors when buying a toilet. It correlates to the overall quality and efficiency of a product. Same goes for corner toilets.

You will want to own a model that is going to save water in your bathroom while flushing the waste impeccably.

While 1.6 GPF is very efficient water consumption as compared to 4.6 GPF in older toilets, there are options available which use 1.28 gallons of water per flush or even less.

They have a WaterSense label so it’s not difficult to recognize them in the crowd. Maybe the difference between 1.28 and 1.6 GPF doesn’t look like much, however, it is a substantial saving in the long haul.

Flushing Mechanism of Corner Toilets

The flushing style plays an important role in water usage. It’s imperative to select the flushing mechanism that delivers powerful flushing.

Choose one that can move waste down the drain line and clean the toilet bowl in a single flush.

This is where dual flush comes into play. Not only it keeps the toilet clean but also conserves water.

Corner Toilet Bowl Shape

With regard to bowl type, you will need to choose between elongated and rounded models most of the time.

Toilets with an elongated bowl are suited for consumers who seek comfort in the first place, while round shaped bowls tend to be low profile options.

There are also square bowls that are tailored for those looking for something more unique.

Measuring The Rough-In For Corner Toilets

corner toilet rough inIt is important to measure your toilet rough-in and choose the right size accordingly. For residential homes, 10, 12 and 14 inches are the most common options.

To measure the rough-in for your corner toilet, you’ll have to take two different measurements.

Simply measure the distance from the plumbing to each side of the wall. Make sure that the distance from each side of the wall is equal.

If you are not sure about the rough-in, consider hiring a professional plumber. That will help you avoid hefty repair costs later.

Design & Look

Most corner toilets aren’t lacking in style despite being compact. That’s because they are made of highly durable, easy-to-clean materials. These units are available in so many varieties to cater to specific design requirements while fitting in any corner.

Some models come with a special finish like Reno-Gloss and EverClean for enhanced cleanliness. These finishes are proven to keep the toilet bacteria and stain-free all the while.

Some corner toilets feature a two-piece construction while others come as a one-piece unit. They are designed ergonomically to minimize body strain and often include soft closing seats for a better experience.

How to Install a Corner Toilet

Before you install a corner toilet, make sure to read the entire manual to get yourself familiar with the process.

Take note of plumbing and building codes. If you are not sure how to install a corner toilet, we recommend you hire a professional plumber.

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 starting the installation, make sure you have the right tools. You’ll need a tape measure, straight edge, level, pencil, shim, an adjustable wrench, caulk, a saw, and tile grout.

Step 1: Measure the rough-in

To do so, measure the rough-in length out from the corner for every wall. Let’s use a toilet with a 12″ rough-in as an example.

Next, draw two perpendicular lines from your original marking. Where these two lines meet will determine the location of your rough-in.


The wax ring will go onto the toilet’s flange (located on the floor) with the flat side being down. Apply a little pressure to hold the ring in place.

Next, secure the anchor bolts through the flange. The bolts should be pointing upwards. This is done so when the toilet is placed,  the bolts will show through the mounting holes.

Step 3: install the toilet & SECURE IN PLACE

As the wax ring is placed down and the bolts are secured in place, lift the toilet and align the holes in the floor with the anchor bolts.

Fix the toilet down on the floor and press in place to ensure the wax seal is secured. Avoid moving the toilet again as you can risk breaking the watertight seal and experience leaks.


Add the washers and nuts on top of the anchor bolts. Ensure the toilet is properly aligned. If not, adjust as needed.

Finish tightening the washers and nuts to the bolts. Do not tighten too much as you may crack your toilet’s base.

Step 4: add the bolt cap 

Put down the bolt caps on each side of the toilet, over the anchor bolts.

If the bolts are much higher than the washers and nuts, use a saw to cut it down to the right length.

Step 5: place the tank bolts through the mounting holes

This should be done if you are installing a two-piece toilet. If you are looking to install a one-piece toilet, add the washers and nuts to the tank bolts.

Ensure the tank is flush and tighten the washers and nuts until the tank firm in place.


This can be found towards the bottom of the tank. Turn on the water and flush the toilet a few times to check if any leaks occur.

If you see no leaks around the base or the back of the toilet, continue to the next step.

Step 7: ADD THE TOILET SEAT & caulk around the toilet’s base

Attach the toilet seat by putting it directly on the bowl and secure it with the bolts from your installation packet.

To finish the installation, use latex caulk or tile grout to seal off the base of the toilet.

Ready to Buy a Corner Toilet For Your Bathroom?

Whether you’re looking to install a one-piece corner toilet or a two-piece unit, corner toilets have their advantages and are particularly suitable for enclosed or limited spaces.

Thanks to their compact design and triangular tank, corner toilets save a lot of space. This makes such toilets an excellent choice for small washrooms, such as basement bathrooms and powder rooms.

Corner toilets carry various flushing systems, bowl shapes and a broad spectrum of features. Efficiency, water consumption, comfort, and power may vary by model.

Remember that fitting a corner toilet will require you to measure the rough-in. Even the smallest corner toilet may not fit if your area is smaller than the required space.
