Best Corner Toilet Buying Guide

Still having trouble making decisions? Nothing to worry about actually, it’s pretty normal to get confused when you have to choose one toilet from several options. In this situation, you can proceed to a decision by considering the following issues.


Now you may wonder, well how many purposes would a toilet serve for other than coming handy for dumping waste? Well, in this case, you’re getting it completely wrong. By purpose we mean, where do you wish to mount it?

The location and the area do matter. You see, corner toilets might be aimed for fitting tight spaces, but not all are constructed the same way. Some structures probably won’t fit the corner, or you yourself might not want them there. Some designs don’t suit all the locations. So, you have to think all these stuff through beforehand.

Then comes the measurement. As already mentioned above, not all corner toilets are constructed following the same measurements. So measure your targeted area first, and then search for a great toilet that fits it.

Sitting Convenience

You wouldn’t want to bend extra mile while sitting on the toilet seat, would you? We know, nobody would; neither would they want to not be able to use the toilet correctly due to its improper height. Have to be careful about that, check the height before settling with an option.

Also, keeping user’s convenience in mind, manufacturers are mostly constructing ADA compliant structure nowadays. It’s better to go with those toilets since they’re convenient for everybody.

About the good toilet seats, many toilets include them, many don’t. There’s no harm in purchasing a toilet without a seat, but finding one that perfectly fits your toilet can be a challenging task. So, purchasing one with it will surely save you a lot of browsing later on.

Again, round and elongated, both bowl options are available for corner toilet. The choice is all yours, both bowls come with their own set of privileges.

Construction Material

The material plays a great role in a toilet’s service for two reasons. For one, the durability of the structure depends on it, and so does the proper cleaning. Vitreous China is a popular option in this regard because it’s durable and debris can’t remain on it for a longer period. However, the possibility of easy cleaning gets higher, as the surface gets glossier.

Flushing System

How delicate this issue can get, it doesn’t have to be explained to anybody; everybody knows. So, check out the flushing system beforehand.

Wasting is never a good thing, especially when it’s a natural resource like water that we can’t survive without. Many manufacturers are implying technologies to reduce the amount of water required for a powerful flush. It’s best to go with a minimalist design that supports that concept.

Also, the design of the tank, how the features inside it take care of the whole situation is some important things that mustn’t be ignored while you’re searching for the best.


The toilet is directly connected with plumbing, so wrong mounting can lead to a number of horrible situations. In order to avoid such a disaster, it’s important that you know what you’re doing.

Sometimes the bowl and the tank come joined as in one-piece toilets, sometimes separated as in two-piece toilets. Because of the structure, two-piece toilets require more work than one-piece toilets; however, you have to be careful in every situation.

One can easily estimate how the installation process will go for a particular model, but still, they can always take help from manuals, websites and guidelines. For your convenience, we have mentioned some necessary steps right here, under this guide.

What we were trying to say is, be sure of the installation process before you make up your mind.

Installation Process for Corner Toilets

Although there might be some alteration in the process for different toilets, the basic steps are all the same. If you’re willing to install it on your own for the first time and feeling nervous about it, don’t. Just follow these steps.

Step One.

Make sure nothing is leaking and no old remnants of the previous toilet are still there. Also, turn off the water supply before proceeding.

Step Two.

Take the necessary measurements and mark the required spots with a pencil. Use a measuring tape or scale for this purpose.

Step Three.

Take the wax ring and place its smooth side over the toilet flange. Carefully press it for a firm mount on the spot.

Step Four.

Take the anchor bolts and pass them through the tapered side of the ring. The toilet is supposed to be pinned to those bolts.

Step Five.

Toilets usually feature installation hole at the bottom. Align those holes with the bolts pointing out of the ring. Now, slowly lower the toilet.

Step Six.

After placing it, press it gently to settle the toilet in its place. Complete the task by inserting needed nuts and washers onto the bolts, and fixing them permanently with the help of a wrench. In the end, add the caps on the top of the bolts.

Step Seven.

Adjust and settle the tank by repeating the same process again with the tank and the rear top of the bowl. You have to place the tank over the bowl first in case it’s a two-piece toilet.

Step Eight.

Now take the seat and attach it with the bowl.

Step Nine. 

In order to enable water supplying, join the water tube with the tank. But don’t turn on the supply after this very step.
