This is a high pressure toilet from the Highline range of KOHLER. Packed with a number of features to improve comfort, whilst retaining solid flushing performance. Lets look at the specifications below.

This is a two piece installation, which has an elongated shape bowl that is taller in height to the seat than many standard bowls. In effect, this means its comfort height which complies with ADA standards.

The flushing mechanism is operated via the trip lever on the left of its tank, which will send 1.4 gallons of water through the bowl.

Not quite what the EPA outlines as efficient, but it will effectively clean the bowl. The MaP flush rating of 1000 grams backs this up further.

On the negative side of things, I wouldn’t say this is the nicest looking I’ve come across, plus the supply line and seat isn’t included. But for whatever you make of those things, consumer feedback tends to be more on the positive side, which is a good sign.

American Standard 2462.100.020 Cadet

Our reviews of American Standard toilets will tell you plenty about what our thinking is of them as a company, and what they can offer the modern home.

But focusing on the 2462.100.020, this stands out for a couple of reasons. The first being its water consumption, and the second being the price. Lets look at the specs further below.

Perhaps something that isn’t always a certainty is the efficiency. Yes they can fall under the standard 1.6 GPF range, but they don’t always fall under the WaterSense criteria, which is exactly what this unit does, with 1.1 GPF.

The manufacturer states that this can save you up to thirty one percent in water each year. That will be an incentive for those wanting more economically friendly hardware in the bathroom.

It fits a twelve inch rough in, and is two piece, which is quite common among this style. The additional EverClean glazing will help prevent germs and bacteria from growing as well as providing a slick surface for the flush to clean out the bowl effectively.

It’s reasonably inexpensive too, not quite bargain basement, but very affordable compared to some of its competitors.

The 77001WHCO1 is a lower budget alternative manufactured by Niagara for those not looking to spend too much, but still achieve an acceptable and decent flushing performance.

Other notable inclusions that can’t be ignored like ADA compliance will make it easier to sit and stand without working your joints and muscles as much as standard height bowls.

Instead of a trip lever, you have a button on top of its tank, which will push water through the floor based waste outlet.

Overall, this is a cheaper option that has been well received by consumers around the web looking at reviews from several sources.

From the Yorkville range, this power toilet includes some good specs that will aid the user rid the bowl of waste effectively all the while using low quantities of water.

Operates on Siphon jet action, which will use up to one point six gallons. Smooth glazing and a EverClean surface work well with this to ensure the bowl remains free of bacteria build up and mold.

And whilst some loos tend to be a bit bulky, this unit isn’t so bad with dimensions of 30 inches by 30 inches by 21 inches. For a medium sized bathroom, this shouldn’t present too many problems.

It has an elongated bowl, and nice design finished in white, with a chrome metal trip lever to activate the flush.

How does a pressure assist toilet work?

Pressure assisted toilets offer a strong flush, but they cost more than other toilet types. These toilets have a pressure tank inside that works like a big water balloon.

Water fills the tank and is held there under pressure. When the flush valve opens, pressure and gravity combine for an explosive flush.

When a pressure-assisted toilet is flushed, the compressed air in the air chamber is released. With the pressure joining the force of gravity, the downward flush is somewhat explosive, leading to a very quick and efficient emptying of the toilet bowl.

You might think this would make pressure assisted toilets very popular. But the drawback is that the explosive flush can be quite loud, which is enough to dissuade many people from wanting such a toilet in the home.

Another drawback for many homeowners is that the mechanism seems unusual and may be hard to purchase.

In reality, however, a pressure-assisted toilet mechanism is relatively simple, consisting only of a sealed plastic drum, a flush cartridge, and a water intake valve.

While all manufacturers of pressure-assisted toilets use identical parts, most hardware stores don’t carry them. And although plumbing supply houses carry the repair parts, they very rarely sell to non-plumbers.

Who needs the best pressure toilet most?

They are made specifically for those who need extra power in waste disposal from the bathroom. This can be for several reasons. Typically, you will find them in commercial settings where bathroom usage is frequent and there is a need for higher performance whilst limiting the amount of water wasted.

However, that doesn’t mean you can’t implement and install one in the household. The pressure assist style is a great option for those of you who prefer bulk performance over the standard gravity style variants. Both have their benefits and drawbacks, it comes down to your own personal requirements.

Pressure-Assisted toilet vs. Gravity-Flow Toilets

From the outside, toilets can take on many appearances–they can use an elongated bowl, for example, or use a sleek one-piece design.

Inside, though, the working guts of the toilet will use one of only two designs. Either the toilet will use a traditional gravity-flow operation, or it will use a pressure-assisted mechanism.

Pressure-assisted models are usually found in commercial settings, like restaurants, although they are starting to become more common in residential bathrooms. Power-assisted toilets are based on a tank-inside-tank model. As water pumps into the toilet tank from the water supply valve, it creates air-pressure in the tank chamber. This sets the stage for a slightly different type of flush cycle that what occurs in a gravity flow toilet.

Regardless of the features, we still place high value on how aesthetically pleasing a product is. The problem in this department is that they are typically two piece designs which don’t usually have those sleek, contemporary themes to them.

Pressure assist toilet considerations before buying

Rough in

Which is why it’s important to get ensure your measurements are accurate.


It doesn’t matter if you live in an apartment, cottage, bungalow, or any other type of house for that matter, knowing how much floor space availability you have is critical in choosing the right product that makes the most of what’s given to it.

If you have what most would consider to be a smaller sized bathroom, then you should be on the lookout for a unit which is more compact in its design.


Whilst there are plenty of hidden gems from relatively unknown companies waiting to be found, we recommend going with the bigger brand names as they tend to attract more consumers that leave a bigger range of feedback for you to digest and use to your advantage.


The color you pick is going to have an effect on your overall bathroom appearance. The top flushing toilets offer a lot of choice in colors.

So spend time thinking about which color will compliment things like the wall, ceiling, tiles, and faucets. This can often be overlooked, and shouldn’t be because it will help it feel more homely if you get it right.

Colors like cream, ivory, bone, linen, and cotton white are all popular choices as they are bright and work well with sunlight, which can help brighten up a previously dark and miserable room.


Read the warranty policy offered before you buy anything. It’s important to ensure you’re adequately protected in the event that something should break or go wrong.


For the majority of cases. Performance and aesthetics are the main selling points that people are interested in. With that being said, you can get your hands on a product that has both for less than five hundred bucks.

We’re of the opinion that you don’t need to spend more than this for an effective replacement. So we suggest setting yourself a budget within this limit.
