This toilet manufactured by Signature Hardware is the top pick of the review because of its quality, characteristics, and affordable cost. The material of this two-piece toilet is china, and it has a convenient elongated bowl. It is average in terms of its dimensions and won’t take a lot of space in your bathroom.
The seat height of this toilet is 17 inches, which is approved by ADA and is considered a comfort height. The weight is 91.7 pounds, and the rough-in size is 6.5 inches, which are both quite standard for toilets of this type.

When it comes to its flushing technology, the Ebler toilet has a dual-flush function. It saves a lot of water and uses only 0.8 or 1.6 gallons per flush. While it effectively flushes all the waste, it works fairly quietly so you won’t disturb anyone at night.

This model is a two-piece toilet, but the installation process is not complicated once you are familiar with the system. Overall, this toilet offers a great combination of the reasonable cost and all the basic functions you may need.

Pros:Cons:
  • Comes with the limited lifetime warranty

dimensions:25.6 x 15.4 x 33.07 inches
comfort height:yes
flush type:dual flush
water consumption:0.8/1.28 gpf
bowl shape:elongated
rough-in:12 inches
material:ceramic
certification:ada
warranty:1 year

The next well-made toilet on this list is Swiss Madison Calice. One of the first things you notice about the toilet is its modern and stylish design. It comes in white color and is made of glossy ceramic material that is both easy-to-clean and durable.

In terms of its shape, it has a skirted design and an elongated bowl that works well for saving space. This is a two-piece toilet, so it’s something to consider before you buy it. The rough-in size is one of the most common ones – 7 inches. The seat height is around 17 inches, which is considered a comfort height, so the toilet is ADA certified.

The toilet has a powerful dual flushing system and uses 0.8 or 1.28 gpf depending on the button. This is definitely a reduced amount of water, so you don’t waste it. In addition, flushing is not too loud, which is surely a bonus.

The installation process requires you to connect two parts with bolts, so you may need to invite a plumber. Overall, this is a high-quality toilet with an interesting design.

Pros:Cons:
  • Elegant and modern design
  • Dual flush technology quickly removes waste
  • The toilet has comfort height and ADA certification
  • Comfortable elongated bowl
  • Warranty is limited to 1 year

3. Signature Hardware Kennard – An Affordable Wall Drain Toilet With a European Design

dimensions:31.75 x 16.5 x 28.25 inches
comfort height:yes
flush type:gravity dual flush
water consumption:0.8 / 1.6 gpf
bowl shape:elongated
rough-in:7 inches
material:porcelain
certification:ada
warranty:limited lifetime

Another toilet that you should consider is Signature Hardware Kennard. The model has a classic European design and is made of porcelain. What is great about this type of toilet is that you don’t have any pipes showing and thus it has a cleaner look.

The coating on the material ensures that you can remove waste without too much effort. The toilet is available only in the white color, which is a standard choice for most people.

When it comes to the shape, it has an elongated bowl that has a height of 17 inches with the seat. You don’t need to buy the seat separately, as it comes with the toilet. Just like the previous models, this is a two-piece toilet and it’s fairly lightweight – 81.25 pounds. The rough-in size is 7 inches, so it’s likely to work in your bathroom.

The toilet has a useful gravity dual flushing feature. It uses either 1.6 or 0.8 gallons of water per flush, which is considered a reduced consumption.

You probably need to have this toilet installed professionally, as installing a two-piece toilet can be too difficult for non-specialists.

Pros:Cons:
  • Water-conserving flushing technology
  • Clean European design
  • High-quality porcelain material with easy-to-clean coating
  • It has a comfortable height
  • The installation process requires professionals

comfort height:no
flush type:pressure-assisted
water consumption:1.1 gpf
bowl shape:elongated
rough-in:4 inches
material:vitreous china
certification:watersense
warranty:2 years

American Standard Yorkville is an affordable two-piece toilet that not only has a pleasant design but also is great for conserving water. It has a classic look with an elongated bowl and white color. The material it uses is durable vitreous china, which is often used in toilets to ensure their durability.

It has a glossy EverClean coating that makes it sturdier and also helps achieve easier cleaning of waste. One drawback of this model is that its bowl height is just 15 inches, so it may be too low for people with disabilities.

Another thing to discuss is its flushing system. This toilet relies on the pressure-assisted siphon and has a water-conversing technology in place. It has a single regime and uses only 1.1 gallons per flush. Even though this is a minimal amount of water, the system has no problems removing waste.

The rough-in size is only 4 inches, which is something you should pay attention to before installing it. The two-piece toilets are known to be more challenging to install, but overall, the process is not too difficult.

Pros:Cons:
  • It doesn’t have a comfort height

5. Kohler Barrington – Back Flush Toilet With Modern Pressure Lite Technology

dimensions:28.75 x 21.25 x 29.25 inches
comfort height:no
flush type:pressure lite
water consumption:1 gpf
bowl shape:elongated
rough-in:4 inches
material:china
certification:watersense
warranty:1 year

Last but not least, I decided to add Kohler Barrington to this review of rear discharge toilets. This is an affordable two-piece toilet made from china that comes in a white glossy finish.

Just like other models here, it has an elongated bowl that generally occupies less space and is more comfortable to sit on. What is important to mention is that it has a left-hand trip lever and a 4-inches rough-in, so keep this in mind if you decide to purchase it.

A water-saving pressure lite technology is one of the main advantages of this model. It uses just 1 gallon of water per flush without sacrificing the effectiveness. It remains quiet when you flush, which is another important characteristic. Thanks to its reduced water consumption, it has the WaterSense certification.

In terms of the price range, this is certainly an affordable toilet. The installation process needs someone who can assemble a two-piece toilet. The advantage of this design is that you can replace both parts separately if you need to over the years.

Pros:Cons:
  • It uses a pressure lite water-saving technology
  • Made from china with a proper glossy finish
  • Great design with an elongated bowl
  • Easy to clean
  • The left-hand trip lever won’t work for some bathrooms

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.

Warranty

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