Factors to Consider in Buying a Corner Toilet

A toilet has several names, but no matter what you call it, at the end of the day – a toilet is one of the most essential things to have in your home. It’s a place where you have your vulnerable moments – so ensuring that you have the one that suits your tastes the most is imperative.

But it’s hard to do your business on a cramped up bathroom with so little space to move. And that’s why manufacturers and companies have started to make a move to meet the demands of people who’re in such a situation and thus coming up with corner toilets.

If you’re in the market for one, this buying guide might be of help in pointing you to the right product.

There are several key factors and benefits that need to be considered when browsing around the market for the best corner toilet. Paying attention to those details would mean getting a sub-par corner toilet to a great one. 

  1. Dimension

If you only have a limited space to work with on your bathroom, then this factor should be the main focus. One thing to keep in mind in checking out corner toilets is that, every single toilet has different dimensions, and that you need to be careful in choosing one. It may have the functionalities and qualities that you need, but you can’t even utilize them if it doesn’t fit in your bathroom. Because you can’t just install a toilet anywhere, especially where there’s no septic tank, the waste would have nowhere to go.

Toilets are made with differently, depending on what it’s secondary purpose is for. Some are made to fit tight and compact spaces, while others are bulky and large to add aesthetic to the bathroom.

Another thing to consider is, where are you installing it? Are you buying a corner toilet for a boat, an RV, a camper van, a cabin, and etc.,

Before even going around shopping for a new toilet, measure the dimensions of your bathroom first, decide where to put your new fixture, and then you can go look.

  1. Water Efficiency

Climate change has been a problem for a long time now, and we’re currently in an all time low. Clean water is already hard to come by, so we must do everything that we can to help, and one way of helping is not contributing to the problem even more.

Technological advancement has made our lives better, but it comes with a price. With all the waste materials that we’re creating, it damages the planet furthermore, and it’s not different with wastewater, which needs an enormous amount of energy to treat, which isn’t good for the environment. One more obvious reason to go for a water-efficient toilet is the water bill. The lesser the amount of water you use, the lesser your bill will be, it’s as simple as that.

There are many toilet brands in the market that are making water-efficient designs. Utilizing only a minimal amount of water, but still gets the job done better than other toilets by increasing water pressure, or utilizing gravity.

You can also go for models with dual flushing technology, allowing you to choose the appropriate flushing option to get rid of your waste whether it’s solid or liquid.

  1. Seat Height

Something as minor as seat height can make all the difference when it comes to comfort. If you have kids in your household, then getting a toilet that’s higher than the standard wouldn’t be ideal, but if you have elders, a higher toilet seat would be better.

  1. Surface and Material

If you’re getting a corner toilet, that means you are in for a long ride. If a corner toilet gets taken care of properly, then you won’t have to be worried about replacing your toilet for another ten years. The durability of a corner toilet, or any item in general, would depend on the materials used in making it. For example. A toilet that is made with Vitreous China would have no problem reaching that ten-year life span.

Besides focusing on the materials that are used in creating the toilet, there are other toilets in the market that has their surfaces coated with anti-bacterial properties, reducing the chances of mold and the likes from forming, while also preventing other wastes from sticking onto the surface.

The toilets that have this function are marketed as “self-cleaning” because of its ability to maintain and clean itself through flushing.

  1. Flush Power

In the past, it’s understood that a smaller a toilet is, the weaker its flushing power is. But that’s not the case anymore – technological advancement has allowed manufacturers to innovate further in their design, allowing for more bolder and better toilets.

There are corner toilets with different flushing types available in the market right now that’s compact in size but deliver quite a powerful flush, while still being water efficient. The secret to that is the water pressure of the system.

Some utilize the help of gravity to create a more powerful flush – the flush valve releases the water from the tank with force, usually covering 360 degrees of the bowl, and employ the help of gravity to further increase the power of the flush.

Some toilets use siphon jet flushing systems. If toilet bowls are made to utilize siphon jet systems, then the bowl is usually created with a molded pocket situated at the front of the bowl that’ll hold water until it’s time to flush. And if a flush is initiated, the vacuum or siphon system sucks all the water out from that pocket, increasing its pressure and power for more efficient cleaning.

Final Words

A corner toilet may not be as popular as the other type of toilets, but if you have a small house and bathroom space to work with, then it can be very useful. The way it’s installed diagonally gives you that ample space that you need, allowing you to be comfortable in sitting even in cramped spaces.

Every single function and feature of a traditional toilet can also be found in a corner toilet. All that’s needed is to look for it with the help of our guide.

Unknowingly we all are doing certain hygiene mistakes while using bathroom and toilets. Hopefully, our tips have brought you some awareness about the cleanliness of toilets and I’m sure our guide has taught you some things that you can use in deciding what and which corner toilet to get.
