Buying Guide

Types of Toilets

Kohler toilets come in different types and varieties such as:

2-Piece Toilets

This is the most common design, which consists of a separate tank and bowl. The traditional style of toilet is commonly installed in homes and offers excellent value. Usually, 2-piece toilets require a toilet seat, that is sold separately. The only limitation of the 2-piece toilet is that the seam is quite difficult to clean and is an area that is quite prone to bacterial growth. 

1-Piece Toilets

1-piece toilets are made from a single piece of ceramic and have an integrated tank and bowl. These toilets have newer technology and hence come at a premium. 1-piece toilets have many benefits.

They are easier to clean because there is no seam between the bowl and tank. The seamless design makes 1-piece toilets shorter by several inches compared to 2-piece toilets. And, finally, 1-piece toilets require little/no assembly.

Intelligent Toilets

Intelligent toilets have several features which make them intelligent. The tankless design of intelligent toilets is very stylish. Intelligent toilets offer various innovative features and functions such as automatic flushing, warm water cleaning, heated seats, etc.

The toilet features an intuitive touch-screen remote and you can control all the settings such as cleansing, temperature, etc. via the remote.

Wall-Hung Toilets

Wall hung toilets are ideal for bathrooms having limited space. These toilets have a very sleek design and the toilet is very easy to clean.

The toilet has a water tank that is hidden in the wall and the bowl and the flush plate are wall mounted, which creates a streamlined profile that offers almost up to 12 inches of space saving compared to a floor-mounted model.

Gravity Feed vs Pressure-Assisted Toilets

Gravity-Feed Toilets

Gravity-feed toilets have a flush valve which depends on gravity. The water falls from the tank into the toilet bowl and helps the waste to move down the drain. Typically, gravity-feed toilets can work with just around 10 lb/sq. inch water pressure.

These toilets flush more quietly compared to pressure-assisted toilets. However, the cheaper models may not displace the waste very effectively.

Pressure-Assisted Toilets

In a pressure-assisted toilet, the water compresses the air inside the sealed tank. This creates pressure which forces the waste to go down the waste line. This type of toilets is especially good for larger families.

However, before you buy a pressure-assisted toilet, ensure that your bathroom has a minimum of 25 lb/ sq. inch water pressure for the toilet to work properly. Pressure-assisted toilets are quite noisy and are also expensive.

Things to Consider When Buying a Kohler Toilet

Before you go out and purchase a toilet for your bathroom, here are a few factors to consider.

Shape and Size

The shape and size of the toilet are important factors to consider. Not only do these play an important role in the amount of floor space the toilet will occupy in your bathroom, but also how comfortable you are while sitting on it.

Toilets come in compact and elongated shapes. Compact toilets usually have a square or round-shaped seat and occupy 2 inches less floor space compared to elongated toilets. Compact toilets are suitable for smaller bathrooms with limited space.

Elongated toilets, on the other hand, have an oval shape, which most people find quite comfortable. There are also toilets with hybrid bowls, which offer a compact oval shape that saves space and is also quite comfortable.

Flushing System and Water Consumption

The flushing system of the toilet is an extremely important factor to consider. The main consideration of the flushing system is how efficiently it uses water. Typically, a toilet flush uses around 1.6 gallons of water, which can add up to your water bill over the year.

There are other types of highly-efficient flushing systems which make use of very less water, thus saving several gallons of water and therefore a lot of money.

There are essentially two types of flushing systems i.e. gravity flushing and pressure-assisted flushing. Dual flushing systems have become quite popular in recent years as a way of saving water.

These toilets allow you to choose between a partial or total flush and use water accordingly, as opposed to the single-flush system which has only a single option available.

Kohler’s Pressure Lite flushing system is a great alternative because it uses less water when compared to a traditional flush while offering the same amount of power.

Design and Style

Kohler toilets come in a wide variety of shapes, sizes and styles right from the classic, white porcelain toilets to the modern and sleek designs to many others and the choice of the toilet style depends on your personal preference and the general look and feel of your bathroom décor.

Price Range

Depending on the design and style of toilet you choose, the price can vary widely. A floor-mounted toilet can cost between $200 to $800 and the final cost will depend on the exact model you choose and whether you are planning to install the toilet yourself or get a professional to do it for you.

Wall-hung toilets require you to purchase a separate tank and install the tank inside the wall, which can cost a lot more, around $1,500 to $2,000.

Kohler Toilets – Dos and Don’ts


  • If you are replacing the toilet in your bathroom, ensure you choose a toilet with the same footprint to prevent any gaps in the floor.
  • Ensure that you select a toilet that is easy for the person using it to sit and get up.
  • When cleaning your toilet, ensure that you test the cleaning solution on a hidden or not noticeable area before you apply it on the entire toilet surface.
  • Wipe the toilet surface clean and rinse it water thoroughly immediately after you apply the cleaner.
  • Use a soft and damp sponge or cloth to clean the toilet surface.
  • Over time, the toilet trapways and rim holes can get clogged with hard water deposits. Use a commercial cleaner that is recommended to remove these deposits.


  • Do not allow the cleaner to soak in the toilet surface.
  • Avoid using a brush, scouring pad or any other abrasive surface to clean the toilet surface because they will scratch the surface and make it dull. 
  • Avoid using in-tank toilet cleaners because they can damage the toilet’s flush valve and other parts.


Which are Kohler’s quietest flushing toilets?

Kohler’s quietest flushing toilets are their 1-piece gravity models like Rialto, San Raphael and Rosario. These toilets are very quiet when flushing because they depend on the gravity of the water to flow into the toilet bowl and they flush without the water falling a long distance (large head pressure). Pressurized flush tanks or valves make the loudest noise when flushed. 

Does the wax ring come along with the Kohler toilet?

No. Wax rings are not included and do not come along with the Kohler toilet kits. They need to be purchased separately.

Do the T-bolts come along with the Kohler toilet?

No, the Kohler toilet kit does not include T-bolts and you will have to purchase them separately.


Since a lot of your time is spent on the toilet every day, it is always a good idea to invest in purchasing a toilet that is not only stylish but also offers comfort and complete peace of mind while you’re flushing.

And, the toilets from Kohler can do all that and more. The toilets from Kohler have plenty to offer and are a perfect combination of functionality, design and style. With our reviews of the best Kohler toilets and buying guide, you have all the information needed to choose the toilet that is perfect for you.
