Buyer’s Guide on 1.6 GPF Toilet

KOHLER 3811-96 Toilet

Are you ready to make a choice and get an update for your bathroom? Before you do, here are some key things you need to know.

Reasons to Get a 1.6 GPF Toilet

Toilets with 1.6 GPF are designed to provide a quiet and comfortable flush that uses less water with maximum power. These devices also have perfect dimensions to fit any bathroom, regardless of its size. 1.6 GPF toilets are perfect for an eco-lifestyle and are recommended by many plumbers as a working combination of options and usability.

Also, many current manufacturers of plumbing equipment strive to equip their products with water-saving systems. A 1.6-gallon toilet allows you to use less water, creating a powerful stream for efficient waste elimination.

Tips on Buying

On average, a person spends about 100 hours of their life in the bathroom. So, choosing the right toilet is essential, and you have to know some key points beforehand.

Material

Material is a vital criterion to consider when it comes to choosing a suitable toilet.

Sanitary ware made from china is more durable, resistant to the effects of household chemicals, easy to clean, and strong.

  • Faience toilet bowl

Faience sanitary ware also provides high quality and durability; however, compared to china, faience toilets last no more than 30-35 years.

Washout

The next step you should take is to determine the type of flush. There are only two of them: direct and circular flushing. The best type is the circular one since when descending, the water washes over the entire bowl, which is more correct from a hygienic point of view.

In some models of toilets, two types of flush can be present at the same time: direct and circular, which are regulated by two buttons. Thus, you should use a circular flush first and then a direct flush.

Toilet bowl height

The proper height of the toilet affects the comfortable and correct position of the human body. Sit and try the model you’re about to buy, and if you feel any discomfort, look for another option.

Also, many manufacturers specify the right height on their toilets to let you know that a particular item suits the whole family. Another option is a comfort height toilet, which is usually 16 – ½” and fits most teens and adults. A standard or regular-height toilet is 14 – ½” in height, which is considered the most common choice.

TOTO CST744SG#01 Drake 2

Do you still wonder which features your perfect 1.6 GPF toilet should have? Check out these questions to make sure that you can make the right choice.

Which toilet model is better, 1.6 GPF or 1.28 GPF?

1.6 GPF toilets consume more water, thus providing a more powerful flush than 1.28 GPF toilets. They effectively wash away large amounts of waste per flush and leave no stains on the bowl. However, the choice also depends on a person’s needs. 1.28 GPF toilets have their pros to consider, like using less water and being lightweight.

When did toilets go from 3.5 GPF to 1.6 GPF?

The pursuit of these toilets dates back to 1994. People seriously thought about saving water in all spheres of life, so the decision was made to reduce the amount of water to drain.

Do plumbers recommend 1.6 GPF toilets?

Many professionals face the question of 1.28 vs 1.6 GPF, and the second option occupies the winning position because of the powerful flush it creates using less water.

Best High-Velocity Flush Toilet with 1.6 GPF

When choosing a suitable toilet, remember that the water level in the bowl should be low to prevent splashes and use less water for flushing. Now, when you learn how to choose an efficient 1.6 GPF flushing toilet, use your knowledge to find the one that is made of solid material, has all of the options you need, and provides a long service life. The Kohler brand makes their plumbing equipment compatible regardless of the collection.
