Below you will find 1.28 GPF toilet reviews, so you can get a better idea of what characteristics they have.

1. KOHLER Cimarron – Best 1.28 GPF Toilet at a Reasonable Cost

dimensions:27.25 x 17.63 x 30.5 inches
comfort height:yes
flush type:gravity
water consumption:1.28 GPF
bowl shape:round
rough-in:10 inches
material:china
certification:ADA
warranty:1 year

The toilet that I have chosen to be the top pick of this review is Kohler Cimarron. In terms of design, it looks traditional thanks to its shape, white color, and round bowl. Besides being quite compact, another advantage of Cimarron is its comfort height, so it can be used by people with disabilities.

Just like all other toilets in this review, this model uses only 1.28 gallons of water per flush. This is definitely a water-saving toilet that has an effective AquaPiston gravity flush system, so it quickly removes waste despite using less water.

It is a two-piece toilet with a 10-inch rough-in, which are important characteristics to keep in mind before installation. You need to assemble the tank and bowl parts, so you may need to have this done professionally. Overall, this is a high-quality toilet at a reasonable price.

Pros:Cons:
  • Affordable cost
  • Classic design with a round bowl
  • Water-saving flush system
  • Comfort height
  • The supply line and seat are not included

2. American Standard H2Option – One of the Most Effective 1.28 GPF Water Conserving Toilets

dimensions:15 x 29.75 x 30 inches

flush type:siphon jet
water consumption:0.92 / 1.28 GPF
bowl shape:elongated
rough-in:12 inches
material:vitreous china
certification:WaterSense
warranty:5 years

The runner-up of the review is the H2Option toilet from American Standard. The toilet is made from durable vitreous china and is available in three shades – bone, linen, and white. It has an elegant design with a comfortable elongated bowl.

As opposed to the top pick toilet, this one doesn’t have a comfort height. The surface is coated in the EverClean glaze that prevents any waste from accumulating.

The flushing system of this toilet doesn’t disappoint. It has a dual flush feature, so there is a button that uses 0.92 GPF and also another one that uses 1.28 GPF.

The toilet weighs 70.1 pounds, which makes the installation process easier. Still, this is a two-piece option, so it requires some experience.

Pros:Cons:

  • Everclean surface for easy cleaning

This toilet combines all the great features you may need – a stylish design, an elongated seat, a comfort height, and vitreous china material.

Another important part of the toilet is its flushing technology. This one uses the so-called Tornado Flush system that gets rid of waste in just a single flush yet uses only 1.28 gallons of water. The toilet has WaterSense, so you can be sure that it’s eco-friendly.

The installation is quite easy, thanks to the fact that it’s a floor-mounted one-piece toilet.

In terms of its characteristics, it has a 12-inch rough-in, comfort height, and a left-hand trip lever. One thing to note is that the seat is not included.

Buyer’s Guide: What You Should Consider

Kohler 3810-0 Santa Rosa Comfort

Choosing a toilet may seem like quite a chore because you have to consider its dimensions, features, material, rough-in, and such. Here are recommendations to help you decide.

Why people use 1.28 GPF toilets?

There are two main reasons for using these types of toilets. Firstly, this option allows you to save money on your water bills, as the water consumption will be significantly reduced. Secondly, saving water helps the environment. Fortunately, modern toilets have enhanced flushing systems so they can work just as effectively while using less water than previous models.

Tips on Buying

Doing your research is essential before buying a toilet. Here is what you should know before you get one.

Standard or comfort height

The height of the bowl from 17 to 19 inches is considered a comfort height. It is great for people with disabilities and those who don’t want to put stress on their joints. If the bowl height is 16 inches and under, the height is standard. This is an important characteristic to pay attention to.

One-piece or two-piece

One-piece toilets are usually easier to clean and install. However, these options are also more expensive. If you want the most budget-friendly option, it is better to look into two-piece toilets.

Elongated or round bowl

Another thing to consider is the bowl shape. If you want to save as much space as possible, the round one is the way to go. An elongated toilet is generally more comfortable.

Standard or dual flush

The dual flush system often makes toilets more expensive, but it can be a good investment. You should consider whether you want to save even more water by choosing dual flush or it is enough to have a single flushing mode.

FAQ

Toto MS604114CEFG#01 Toilet

Here are a few frequently asked questions about water-saving toilets you might have.

What is a WaterSense toilet?

The term refers to toilets that have the WaterSense certification. It means that a WaterSense toilet meets the water-saving criteria set forth by the WaterSense organization and has undergone third-party testing.

How to use less water in the toilet?

When it comes to toilets, the only effective way to use less water is to choose a water-conserving toilet. To be considered a water-saving toilet, it needs to use less than 1.6 GPF. It is also a good idea to select a toilet with a dual flush system.

How much water does a dual flush toilet use?

It depends on a particular model of a toilet. Many toilets with the dual flush function use 1.6 GPF on one button and then half of that amount, 0.8 GPF, on a second button.

Effective Water-saving Toilets for Your Home

It can be difficult to choose the right toilet, as there are so many things to consider. A water-saving flush system is one of the most important aspects because it is both better for the environment and also more budget-friendly.

In my opinion, KOHLER Cimarron is a top pick because it has a modern design, a comfort height, and an effective flushing system. And, it is also affordable.
