Best Corner Toilets of 2024 (Trianglular Tanks)

When it comes to making the most of the space afforded to you, a toilet with a triangular tank could be ideal as they tend to squeeze nicely into a corner between two walls. The ability to do this frees up space to be used for other fixtures and accessories like sinks and showers.

Unlike compact toilets, these cater to a very specific design requirement. We aim to help readers find a good fit for their bathroom by using our buying guide below that analyzes the various brands, shapes, dimensions, exterior and much more.

Renovator's Supply Sheffield 13762

Aside from the obvious triangular shaped tank, the 13762 model has several things going for it. Lets take a look at some of its stand out features below.

The seating height is listed as fifteen inches which is good news for fans of standard bowls. Not so much for chair height fans, whose preferences are for something more accessible and easier to sit down upon. The bowl is round and it's finished in white, and will project thirty two and a half inches from the corner.

It will fit a twelve inch rough, and will give people the choice of two flush powers. Also known as a dual flush mechanism. This will operate via a button rather than a trip lever, and will utilize either 1.6 gallons or 0.8 depending on the situation and waste.

Reno gloss will ensure it's easy to wash, and maintain, while making it easier for water to send waste through the outlet with less sticking and staining the bowl.

A potential match for consumers working with a smaller budget.

American Standard 270AD001.020 Cadet 3

If it's performance you're after, the 270AD001.020 from American Standard could be exactly what you've been searching for. A 1000 MaP flush rating demonstrates that it handles bulk waste very well. However, with such power, there is a flip side to that. It's not quite as efficient as some of its competitors using 1.6 gallons on a siphonic, gravity fed flush.

What's more it meets ADA criteria, which effectively means the bowl height is slightly taller than your standard models, usually above seventeen inches from the base to the top of its seat. To the rim this measures 16.125 inches, but with the addition of a seat, this pushes it over that criteria. Many see this as a more comfortable way to sit, which is further complimented by the elongated style bowl which enables users to sit in a position that feels natural.

It's equipped with a larger than average sized flushing valve and its glossed with whats known as EverClean surface, which is made to fight bacteria and germs. Which in turn will help reduce odors from rising and ensure the water effectively cleans the bowl.

You'll need to purchase a seat separately to this because it doesn't come with it. The 5325.010.020 Champion slow close is one many people pair it with.

Plenty of feedback from buyers can be found online, which is essential for conducting effective research and gauging its quality. If you've got a mid to upper budget, this is one we suggest keeping tabs on.

Advantages of owning a triangle toilet

So, you have a specific product in mind. But are trying to better understand how they may be beneficial to you over standard shaped loos? We outline several ways in which these may be advantageous to users below.

Saves space - As mentioned previously, the very nature of this product is to limit the floor space consumption. It manages to do this by fitting nicely into a corner. If you tried putting a standard unit in that position, there would be far too much space behind it.

Fit more hardware in - Because you have this extra floor room, you now have the option to fit more fixtures into your bathroom like sinks and showers.

Other considerations

Rough in - Time and time again, we emphasize that you should know exactly what rough in size you require. Ten, twelve, and fourteen inches seem to be the most common in the residential setting, but be sure to measure yours, or hire a professional plumber if you're not sure.

Bowl shape - The main choices you're going to be presented with in your research is one of either elongated or round shaped bowls. Elongated tend to be the go to option for consumers looking for comfort, but round are low profile options, which may be suitable for some of you. Additionally, you can go for something more unique like square bowls.

Water usage - For me, a major part of deciding on the overall quality of a product is how efficient it is. Whilst 1.6 gallons are far better than older styles that used 3 gallons plus, there is still options available that are far more efficient and usually come with a WaterSense label to let you know that. These labels are given to units that use 1.28 gallons per flush or less. The difference between 1.6 GPF and 1.28 GPF may not seem like much, but over longer periods of time, you'd be quite surprised at the savings made.

Price point - There will be quite a bit of variety in pricing here. Things like brand and flushing power comes into play. We recommend setting yourself a budget of around 400 dollars, but it's possible to get a decent model for around 300 bucks too. I'm of the opinion that anything at the 100-200 price range isn't going to give you the performance needed in day to day usage.

Consumer feedback - Look into what buyers have already been saying about a product where applicable. Their insight and first hand experience can proove invaluable when making a final decision. But where to find such feedback? Popular online shops like Amazon, Walmart, and Home Depot are a good place to start your search.

Seating - One thing that can catch people out is that some units don't include a seat. This can easily add another 30 to 50 dollars to the price. So look into whether the seat is part of the package, and what style it is. No slam options are a good bet as they reduce noise and chances of damage.

Wrapping up

As you can see, corner toilets certainly have their advantages. The design is going to save you a lot of space, making them the perfect choice for smaller washrooms like en suites or basement bathrooms. Take away the external design aspects, and you find most units go toe to toe with some of the leading brands on the market. Plenty of variety in flushing types and power, as well as differing bowl shapes and efficiency.

When shopping, follow the advice given above, and this will help reduce the amount of mistakes you make and ensure you know what you're looking for.
