Buyer’s Guide: Things to Consider When Choosing the Right Toilet

Swiss Madison SM-2T120 Toilet

Now that you have considered different rear outlet toilet reviews, it’s important to consider all the important factors to decide whether a certain model will be right for your home.

What is a rear discharge toilet?

To put it simply, a rear discharge toilet is a type that gets rid of waste through the plumbing system in the wall as opposed to draining through the floor. Compared to the wall-mounted options, the rear discharge one is mounted to the floor with bolts, and you can see its tank.

In terms of construction, they are both two-piece and one-piece options available. This type of toilet is considered easier to install and is often chosen when plumbing works cannot be performed under the floor.

What to consider when buying

There are a number of aspects for you to consider before deciding on the right toilet for your house.

Toilet dimensions

The first thing you need to do is measure how much space you have in your bathroom for the toilet. Rear discharge toilets use P-trap pipes, so you should make sure that this system can also fit in your bathroom. You should also make sure that you have enough space for your hand if a toilet has a lever on one side.

Rough-in size

Rough-in sizes differ from one toilet to another. This measurement refers to the distance from the base to the center of the outlet pipe. The rough-in sizes can be anywhere from 4 to 14 inches depending on the toilet type, so it’s one of the first things to pay attention to.

Comfort or standard seat height

Another essential thing to consider is the toilet seat height. The ADA-approved comfort height for people with disabilities or those who may have some joint problems is 17 to 19 inches. Anything below 15 inches is considered a standard height, and it may not be convenient for some people.

Shape of the bowl

The most common bowl shape for modern toilets is the elongated one. It is considered more largely considered more comfortable, but it all depends on your preferences. Those who don’t like an elongated shape can choose the round one.

Flushing technology

When it comes to flushing, pressure-assisted technology is most commonly used in rear discharge toilets. There are toilets that use a dual flush technology, which is also quite convenient. You should also pay attention to how loud a certain toilet flushes, especially if your bathroom is located close to the bedroom.

Water usage

Another important thing to look for in a toilet is whether it saves water. The WaterSense certification is a sure way to tell that a certain toilet is environmentally-friendly and will also cut down on your water consumption expenses. Anything under 1.6 gallons of water per flush is considered low water consumption.


This aspect differs from one manufacturer to another and can be anything from one year to a limited lifetime warranty.
