Nobody really likes to talk about shopping for a new toilet, but when you need one, you need one. In your shopping around you may have heard about a new-fangled idea called wall-mounted units and wondered if one was right for you. A wall mounted toilet brings a lot of innovation to the table, but there are some things you should be aware of. But as a wall hung toilet with a lot working for it, the Glenwall is an amazing option.

Product Details

This is a nice looking wall mounted toilet with great features. It has the look of a standard tank toilet, but still allows you to clean underneath without navigating around a bolted base. It also has an elongated seat which is more comfortable for sitting. It is made by American Standard, a well trusted name when it comes to toilets.

One of the signature features of this toilet is the pressure assisted flushing system. This siphon jet action will clean the bowl significantly better than just normal gravity assisted flushing. The surface is made of vitreous china, which forms when ceramic is fired at high temperatures. When this is done, the ceramic’s natural pores are sealed. A glaze is then applied and the high heat fuses this finish to the body, forming a smooth surface that waste won’t stick to.

Adding to the cleaning ability is the large water surface area. A large water surface area is desirable because the more area the water covers, the less likely waste will fall onto a dry surface and stick. The water surface area for this Glenwall is 10 inches by 12 inches.

This toilet only uses 1.6 gallons per flush, so it is a very low consumption toilet. If you’re upgrading from a toilet that was made in the 90s, you will find your water bill drop drastically. Those older toilets use as much as 5 to 7 gallons of water per flush. The average person flushes five times per day.

That means that for one single person, you can save up to 27 gallons per day. In a single year then, a family of four will see themselves saving just over 39,000 gallons of water.

While we don’t know what you pay for water, the average cost in some state is as high as $15 for 1,000 gallons. At that rate, that volume of savings translates to about $585.

What is Pressure-Assistance Flushing?

A pressure assisted toilet uses a pressure tank instead of just a standard reservoir of water. The tank is sealed instead of open to the atmosphere. As the tank is filled, it compresses the air already in the tank. You don’t need a pump to pressurize it; it is pressurized just from the incoming water (which is usually at about 40 to 45 psi).

Once the air is pressurized, it waits until the toilet is flushed. When that happens, the water and air come blasting out, forcing their way into the bowl of the toilet. This high powered stream scours the bowl clean. As the flush ends, water is let into the tank where it is pressurized once more as it fills up with water.

How Pressure-Assisted Flushing Helps

The primary help that a pressure assisted flush gives is more cleaning power. On average, pressure assisted toilets can fling waste about 150 percent as far as normal gravity assisted flushing. That means you get fewer clogs in the toilet drain and cleaner drain pipes as well.

Another benefit of pressure assistance is that it lets you do more with less. That means you can get better flushing with a 1.28 gallon flush than some toilets can get with a full 1.6 gallon flush. While this isn’t a huge number, considering that the average person flushes five times per day, in a household of four, this can really add up as the year continues.


● Pressure assisted flushing means that you get extra cleaning action
● Large 10 by 12 inch water surface area helps keep the bowl clean
● Uses a flushometer for flushing
● Uses 1.6 Gallons per flush
● Combines the look of a traditional tank toilet with the cleanliness of a wall mounted unit


● Does not come with a carrier or a seat
● Installation can require a lot of remodeling to change plumbing and ensure proper installation


If you need a toilet that looks like a traditional tank toilet but also want the ease of keeping the floor clean, the Glenwall is something you should consider. The vitreous china finish and pressure-assisted siphon jet flushing will help you keep the inside clean as well.
