Toto Toilet Vs Kohler Toilet Key Features Compared

Flushing System

When it comes to the flushing system, both Toto and Kohler have their unique technologies.

Toto’s Tornado Flush system features two powerful nozzles that create a centrifugal, cyclonic rinsing action, reducing waste buildup and keeping the bowl cleaner.

This high-efficiency system is more effective in one flush than most toilets are with multiple flushes.

The modern hole-free rim design means that it performs more consistently and is easy to clean.

On the other hand, Kohler’s Revolution 360 swirl flushing technology sends 360 degrees of water through the bowl for complete coverage.

Their patented AquaPiston flush canister uses a powerful jet to propel water around the bowl, providing a worry-free flush that keeps your toilet cleaner.

Imagine the Toto’s Tornado Flush as a cyclone, swirling water around the bowl, leaving no corner untouched.

It’s like having a mini power washer inside your toilet.

Kohler’s Revolution 360, on the other hand, is like a whirlpool, sending water in every direction, ensuring a thorough and complete rinse.

Both systems aim to provide a powerful and efficient flush, but their approaches are as different as a cyclone is from a whirlpool.

Water Efficiency

Water efficiency is a crucial aspect of modern toilets, and both Toto and Kohler have made significant strides in this area.

Toto’s Dynamax Tornado Flush uses 100% of water to clean and rinse the bowl, using a smaller amount of water more efficiently with a 2.5″” trapway and quieter flush.

It offers three Tornado Flush technologies that eliminate waste with as little as 1.0 Gallon of water.

The Dynamax system provides up to 45% in water savings compared to standard 1.6-gallon toilet systems.

Kohler, on the other hand, has engineered their toilets to achieve the same powerful flush with less water.

They found that re-engineering the canister to send water through a smaller valve with more pressure achieved a more complete flush with less water.

Think of Toto’s water efficiency as a well-orchestrated symphony, where every drop of water plays its part in the performance, resulting in a cleaner bowl with less water.

Kohler’s approach is more like a precision drill team, where every drop of water is directed with precision to achieve a powerful flush with less water.

Design and Style

Toto and Kohler also differ in their design and style.

Toto’s toilets are known for their modern, hole-free rim design, which not only enhances the efficiency of the flush but also makes the toilet easier to clean.

They also offer more High Efficiency Toilet (HET) choices than any other manufacturer, ensuring that there’s a design that fits with your existing or future bathroom décor.

Kohler’s toilets, on the other hand, are known for their sleek and stylish designs.

One of their notable features is the fully skirted design, which makes the toilet easier to clean.

In terms of design and style, Toto’s toilets are like a sleek, modern skyscraper, with clean lines and a minimalist aesthetic.

Kohler’s toilets, on the other hand, are like a classic mansion, with a timeless elegance and a touch of luxury.

Both offer a range of designs to suit different tastes and bathroom decors.

Cleaning and Maintenance

When it comes to cleaning and maintenance, both Toto and Kohler toilets have their unique strengths.

Toto toilets are renowned for their Tornado Flush system, a powerful, efficient technology that uses two powerful nozzles to create a forceful centrifugal action for a cleaner rinse and reduced cleaning frequency.

Imagine a whirlpool in your toilet bowl, sweeping away waste and grime with every flush.

It’s like having a mini power washer right in your toilet, making your cleaning chores a breeze.

On the other hand, Kohler toilets feature the innovative AquaPiston technology.

This patented flush engine pushes water into the bowl from all sides, ensuring a thorough, spotless clean.

Think of it as a 360-degree power rinse for your toilet bowl.

It’s like having a team of tiny, diligent janitors scrubbing every inch of the bowl each time you flush.

Advanced Bidet Functionality

The world of toilets is not just about flushing and cleaning.

It’s also about personal hygiene, and this is where advanced bidet functionality comes into play.

Toto toilets are often equipped with the Washlet bidet seat, offering warm water for rear and front washing.

It’s like a gentle, warm rainfall right in your toilet seat, providing a refreshing cleanse after each use.

Some models even offer adjustable water temperature and pressure, giving you a personalized, spa-like experience in the comfort of your own bathroom.

Kohler, in contrast, offers the C3 bidet seats with adjustable water temperature and pressure, as well as a heated seat feature.

Imagine sitting on a warm, cozy seat in the middle of a cold winter night.

It’s like having a personal retreat, a sanctuary of warmth and comfort, right in your bathroom.

Plus, the self-cleaning wand and the air dryer function add to the convenience, making your bathroom experience not just comfortable, but also hygienic and efficient.


Price is always a crucial factor when choosing a toilet, and both Toto and Kohler offer a range of options to suit different budgets.

Toto toilets, with their advanced features and innovative technology, are often seen as a premium choice.

It’s like investing in a high-end car, where you pay a bit more upfront for superior performance, comfort, and longevity.

Kohler toilets, on the other hand, are known for their value for money.

They offer a balance of quality, performance, and affordability.

It’s like finding a reliable, well-performing car that doesn’t break the bank.

Whether you’re renovating on a budget or just looking for a cost-effective toilet solution, Kohler offers a range of options to meet your needs.

In conclusion, both Toto and Kohler toilets have their unique strengths when it comes to cleaning and maintenance, advanced bidet functionality, and price.

Your choice will ultimately depend on your personal preferences, needs, and budget.


When it comes to comfort, both TOTO and Kohler have made significant strides to ensure their toilets provide maximum comfort to users.

TOTO toilets are designed with features such as heated seats, automatic opening and closing lids, and good water coverage.

These features aim to provide a whole new level of comfort, eliminating the discomfort of cold toilet seats and the hassle of manual lid operation.

On the other hand, Kohler also offers comfort-enhancing features.

For instance, the Kohler Gabrielle Comfort Height toilet has an elongated bowl that offers added room and comfort.

The Kohler Transpose Comfort Height toilet also features an elongated bowl for added comfort.


Durability is a key factor when choosing a toilet, and both TOTO and Kohler have a reputation for producing durable products.

TOTO toilets are known for their unmatched durability and reliability.

They are manufactured with high-quality materials, making them durable and reliable.

This ensures that TOTO toilets can withstand regular use over a long period, providing value for money.

Similarly, Kohler toilets are built to last.

The company’s toilets are designed with a durable canister that has 90% less exposed seal material than a 3″” flapper, ensuring leak-free performance.

This design enhances the durability of Kohler toilets, making them a reliable choice for homeowners.

Size and Space Efficiency

Size and space efficiency are crucial considerations when choosing a toilet, especially for smaller bathrooms.

TOTO offers toilets in various sizes and designs to suit different bathroom layouts and personal preferences.

For instance, the TOTO Drake Two-Piece Elongated toilet fits into 12-inch rough-in installations, making it suitable for bathrooms with limited space.

Kohler also offers compact, high-efficiency toilets perfect for smaller spaces.

The Kohler Adair Comfort Height toilet, for example, features a slim tank and pared-down oval forms, making it an ideal choice for compact bathrooms.

The Santa Rosa Comfort Height toilet from Kohler is another one-piece design that conserves space with a compact elongated bowl.

In conclusion, both TOTO and Kohler toilets offer comfort, durability, and space efficiency.

They come with unique features designed to enhance user comfort, are built with high-quality materials for durability, and are available in various sizes to suit different bathroom layouts.

Color Options

When it comes to color options, TOTO toilets offer a variety of choices, including silver, nickel, and black trims.

On the other hand, Kohler toilets are available in white and beige hues.

While both brands provide a range of colors, TOTO seems to have a more diverse selection.

Touchless Flush Option

TOTO offers touchless flush options in their product line, such as the ECOPOWER smart-sensor flush valves for toilets and urinals.

These flush valves are energy-saving, durable, and provide maximum performance in high-traffic public restrooms.

Kohler also has touchless flush toilets, like the San Souci One-Piece Touchless Toilet and the Cimarron Elongated Touchless Toilet.

Both brands have embraced touchless technology, providing users with a more hygienic and convenient restroom experience.

Noise Level

While specific noise levels are not provided in the search results, a user on Houzz mentioned a humming noise issue with their TOTO toilet.

The noise lasted for about 30 minutes after flushing and was quite bothersome.

However, this seems to be an isolated incident, and it’s unclear if this issue is widespread among TOTO toilets.

Kohler’s intelligent toilets, such as Numi 2.0, Eir, Innate, and Veil, are equipped with advanced technological features, but there is no mention of noise levels in the search results.

It’s essential to consider individual user experiences and reviews when evaluating the noise levels of these toilets.

In conclusion, both TOTO and Kohler offer a range of color options and touchless flush features in their toilets.

While TOTO seems to have a more diverse color selection, both brands provide touchless flush options for a more hygienic experience.

As for noise levels, it’s crucial to consider individual user experiences and reviews, as specific noise level information is not readily available in the search results.

Toto, known for its cutting-edge technology and water-saving mechanisms, is a great choice for those who prioritize sustainability and advanced features like bidet functionality.

However, the smaller design might compromise comfort for some users.

It’s a more budget-friendly option, making it suitable for those who want quality without breaking the bank.

Kohler also offers touchless flush options for those who prefer a more hygienic approach.

If you’re looking for a toilet with advanced features and don’t mind a higher price tag, Toto might be the way to go.

But if you’re after a more budget-friendly option without compromising on quality, Kohler could be your best bet.
