Welcome to ToiletVision

Guiding you to your new toilet.

Finding a new toilet is not an easy task. There are hundreds of high quality toilets on the market, with lots of different manufacturers and a long list of options to consider.

This website gives you the information you need to find your new toilet.
Whether you are looking for replacement of a broken toilet or one for a brand new home, you will find general information but also specifics to meet your needs.

Before you browse the site for ideas (see the toilet articles and toilet reviews sections), read the ‘toilet buying guide’ below to help you define what you want and what is possible in your own home. It is an overview of all the important aspects and common culprits.

The toilet reviews

We use user opinions and user reviews from multiple websites for our toilet reviews, avoiding bias caused by overly positive manufacturer descriptions. We use both factual information such as dimensions and type of design and flushing and experience from users of that specific toilet.

A quick comparison of the bestselling toilets and all time classics: The table consists of high rated different types and brands of toilets. The links next to the image redirects you to amazon.com.

Toilet buying guide

The best toilet for you is highly personalized. It are not only preferences like the look, type (one or two piece, wall mounted etc) and flushing mechanism that are important in making a decision, you also have to weigh factors like the height of the seating and the depth of the toilet. For example: in a small confined place you need a compact toilet so that tall persons will not have their knees against the door.
In the menu you can click “Articles” and “Reviews” to find specific information and toilet reviews before you make a choice, but be sure to give attention to the following before you start scrolling and reading:

Dimensions of your toilet and rough-in.

The most important one. Preferences set aside: it should fit. Be certain that there is still enough room or your legs when you sit on it. Also consider the placement of a sink: will it all fit in a confined place?

Some type of toilets have the water reservoir built into the wall behind the toilet itself, be sure to take the resulting loss of space into account too. Read more about wall-hung toilets here.

When you need to place a toilet in  a confined space that is especially limited in depth, consider  a classic toilet with the water reservoir high above the bowl. This allows you to almost place the toilet against the wall. These toilets are characterized  by a strong flush since the water is able to build up momentum as it flows down. They are difficult to find however.

Also be sure that the outlet pipe of the toilet is in the right place for the new toilet. Not all toilets have the outlet pipe at the same place.

You have to know the “rough-in”. This is the distance between the outlet pipe of the toilet and the wall behind the toilet. You measure it by taking the distance between the bolt caps and the wall of your current toilet. Almost all toilets that are sold have a rough-in of 12 inches. Some have a rough-in of 10 or 14 inches, although this is becoming  rarity. A smaller rough in is not a problem, a larger one is. If you would replace a toilet with a rough-in of 10″ for one of 14″ you might bump your toilet against the rear wall and can not install it.

Shape of the toilet bowl

The most common bowl types are the elongated and the round type. The round type is commonly used in smaller places and by families with small children. Generally, round bowls are also often lower than elongated toilets bowls.

People choose for the elongated type of toilet bowl as it is more comfortably to sit on. A larger part of the legs and buttocks are resting on the seat, spreading pressure of your body and resulting in more comfort.

Both round and elongated bowls are common and many brands sell both an elongated and around bowl version of he same toilet.

Different flushing technology


The siphonic toilet is the most used flushing system in North America. The siphonic toilet has an S-shaped waterway and a bit smaller diameter pipes than other toilets. As you flush the toilet a large amount of water is suddenly dropped in the bowl and all his water goes through narrow pipes. The weight of this water going down creates negative pressure behind it, sucking even more water. Eventually, the water is gone and it sucks air (creating the typical sound). The vacuum is gone and the flush ended.

Apart from the sound you can recognize this type of toilet by looking in the bowl during a flush. At the end of the flush as the water passes the toilet it empies for a moment before it is filled with water again. It is good to keep in mind that the bowl of siphonic toilets is mostly larger than the washdown type toilet, next to be discussed.


A lot less common than the siphonic type but can be occasionally found in the US. They a  most popular in other parts of the world, especially in Europe. From the outside they look like siphonic toilets with the main visible difference being the lower water level. This toilet is usually a bit smaller that the siphonic toilet.

The washdown toilet is a toilet with a different shaped waterway than the siphonic. The mechanism is basically dropping a lot of water in the bowl and letting gravity push everything through. It is simle and elegant. This is why the diameter of the piping is larger than the siphonic type: there is  no vacuum created during flushing and it needs to be able to push everything through based on the weight and speed of the water. As the diameter is larger, it is less likely to clog. It does not produce the distinct sound siphonic toilets make, and makes less noise in general. The water level is lower than in siphonic toilets, making skid marks more likely.


The washout toilet type has a small bowl in the front of the toilet. Stools fall into this small bowl. When flushed the force of the water cleans this bowl, using exactly the same mechanism as the typical washdown toilet. The largest benefit of this toilet is an enormous reduction in the chance of splatter against your buttocks, making it a very hygienic toilet although his would not be expected by many. If one forgets to flush it results in much more poignant odor as other toilets, as stools are not covered in water. Also, these are good toilets for looking back at your stools once in a while, as some early signs of diseases can lead to abnormalities in the stools (fresh blood, old blood (dark, near black stools), discoloration,  worms, etc).

Shelf style

The shelf style / ‘flachspüler’ (German) also has a platform where excrements fall onto. The mechanism is very similar to the washout type. The main difference is that the drain pipe is not in the back of the bowl like the washout and washdown type of bowl, but in the front. This type is not very common in North America, and is more seen in Europe. Benefits are less splashing and being able to take a peek at e(why this is a benefit is described in the washout type section) a downside is the increased odor. As stools do not fall in the water (just a very thin layer of water is on the shelf), this type also has a potential to produce more odor than for example the siphonic/washdown models, where excrements fall directly into the water.

Water use

No available toilet flushes more than the federally mandated 1.6 gallons (in the past this was 3.5 gallons or more), but some toilets use even less water. When they use at least 20% less water (1.28 gallons), they are named high-efficiency toilets. Many dual-flush toilets are also high-efficiency toilets, as a larger flush and smaller flush combined use 1.28 gallons on average or even less.

Dual flush toilets have two buttons/levers, one for the larger flush of 1.28-1.6 gallons and a smaller flush of 0.8-1.28 gallons. These dual flush toilets usually save even more water than regular single flush high-efficiency toilets as most people use the smaller flush more often than the full 1.6 gallon flush.

Toilets using at least 20% less water received the WaterSense label, a label issued by the United States Environmental Protection Agency (EPA) for making it easy to select water efficient products.

The best flushing toilets do not necessarily use more water, as there are toilets using just 1.28 GPF while having a maximum score on the MaP (Maximum Performance, an independent toilet flushing score).

Calculate how much water you flush down every year

Below you can calculate how many gallons of water you use per year for flushing the toilet.

Just fill in the size of your household, the number of times every household member flushes the toilet on average and the flushing volume if you know it. If you don’t know how many gallons your toilet flushed and the toilet is newer than 1994, assume 1.6 gallons per flush. If you have a dual-flush toilet and do not know how many gallons are used in the smaller and larger flush, 1.6 gallons for the larger flush and 1.0 gallon for the smaller flush is a good bet.

More detailed calculations encompassing dual-flush toilets (different volumes of small and large flushes) and water savings by updating an older toilet for a high-efficiency toilet can be found in both main articles: dual-flush toilets, high-efficiency toilets.

Height of the toilet

In the last years height of toilets have increased. The most important reason is increased comfort for elderly and disabled persons. It is easier to stand up from a seating position than a squatting position.

A squatting position is however far more natural than the sitting position when defecating. The squatting position gives less pressure on the side of the rectum making hemorrhoids less likely. Also a high toilet is also not a good idea for those who have constipation as the human pelvis is not designed for defecating in sitting position and makes this more difficult.

When physical ailments do not allow you to sit on a low toilet, higher toilets are readily available. If you have found a perfect toilet but you are afraid this will be too high for you, consider getting a Squatty Potty® or another toilet stool. You place your feet on the small stool, increasing the angle between your legs and pelvis and creating a more natural position. This will help the adults to sit in a more squatting position and help children to sit comfortably on the toilet.

One- or two-piece toilets

A two-piece toilet has a separate bowl and tank. They are cheaper than one-piece toilets, larger and a bit more difficult to clean. If something breaks it is easier to replace a part. If for example a ceramic tank breaks you can replace the tank and leave the bowl, this case of a one-piece toilets you would have the replace the whole toilet.

A one-piece toilet is more difficult to fabricate than two-piece toilets, and you notice this by the heavy price tag. They are however smaller and also easier to clean because there are no crevices between the parts where dirt can accumulate. It is a good option when you have limited space. It also looks more luxurious than a two-piece toilet.

Wall hung toilets

Wall-hung toilets can be beautiful and save a lot of space. They are very practical to clean, as the whole ground surface below the toilet is reachable. There are no visible bolts.
