Black Toilets – Which One To Buy?

Last updated: October 19, 2018

After analyzing 48 toilets that are currently available on the market, we think that the KOHLER K-76301-7 Highline is the best black toilet for medium budgets. It features attractive two-piece design, offers a powerful “Class five” flushing action, and comes with 1 year limited warranty.

We also like the Toto Eco Soiree which is a high-end toilet that comes with one of the most highly praised gravity-fed flushing systems on the market (the Double Cyclone) and features attractive one-piece design.

Now without wasting any more time, check out out 5 brief reviews of what we believe are the most interesting best black toilets on the market right now, or skip to our buyer’s guide.

1. KOHLER K-76301-7 Highline – Our top pick

Kohler is a company that was founded almost 150 years ago and it’s safe to say that it’s one of the oldest toilet manufacturers in the world. They have several black toilets on the market right now, and we decided to pick the K-76301-7 Highline as the most interesting one considering its price, design, flushing system, and efficiency.


Despite the fact that the K-76301-7 is a two-piece toilet, it looks almost the same as it was made of a single piece of material because black design makes the area between the tank and the bowl less visible than on a white toilet.

The elongated bowl combined with comfort height seat provides an extra level of comfort and makes sitting down and standing up easier for most adults.

Flushing system

The flushing technology behind the K-76301-7 Highline is called “Class Five” which is Kohler’s second most advanced gravity flushing system. The only difference between Class five and Class six is that the Class six creates more flushing action at the sides of the bowl.

With that said, the K-76301-7 Highline uses 1.28 gallons of water per flush which makes it certified by Watersense standards. To put this into perspective, the Highline saves several thousand gallons of water per year compared to an old 3+ gallon toilet.


  • Attractive and sleek design
  • Comfort height
  • Class Five flushing technology
  • Three-bolt installation
  • Low water consumption: 1.28 GPF


  • It’s not the most affordable black toilet we have managed to review
  • The seat is not included in the package

2. TOTO MS964214CEF#51 Eco Soiree

The next toilet in our list of recommendations the TOTO Eco Soiree. It’s a high-end one-piece toilet that comes with Double Cyclone flushing system.

The only reason why we didn’t rank the Eco Soiree on the first spot above the Kohler Highline is the price. It is a high-end toilet and it comes with a high-end price which makes it less appropriate for average consumers.


The Eco Soiree is a one-piece toilet which means that the tank and the bowl are made of a single piece of material. This enhances its looks and makes the installation process a little bit easier since you don’t have to mount the tank onto the bowl.

The bowl is elongated and the height of the bowl is 17-1/4-inches which provides more comfort than most smaller round toilets on the market. The bowl surface is finished with Toto’s SanaGloss ceramic glaze which makes it smoother and easier to clean.

Flushing system

The Eco Soiree features the Double Cyclone which is arguably the best gravity flushing system on the market right now.

This means that the Eco Soiree has no rim. Instead of several rim holes that can get clogged up, there’s an opening at the side of the bowl where the flushing water comes out. The water moves around the bowl like a spiral which creates a powerful centrifugal force and efficiently washes the entire bowl.

The Double Cyclone system of the Eco Soiree uses 1.28 gallons of water per flush which means that it’s ultra efficient and certified by WaterSense.


  • Attractive one-piece design
  • Double Cyclone flushing system (1.28 GPF)
  • SanaGloss ceramic glaze


  • High-end price

3. KOHLER 3810-7 Santa Rosa

The Kohler Santa Rosa is another black toilet that offers exceptional performance in a small footprint. It comes in one-piece design which makes it look quite elegant and easier to clean.


The Santa Rosa features Comfort Height seat which means that the height is similar to the height of traditional chairs.

Flushing system

This water-saving toilet uses 1.28 gallons of water per flush which is the same as the Toto Eco Soiree and the Kohler Wellworth. The secret is the AquaPiston canister that allows water to flow into the bowl from all sides and creates as powerful flushing action as traditional toilets that use almost 3x more water.


The Santa Rosa toilet comes with 1-year limited warranty. The canister design has about 90% less exposed seal material than traditional toilets, so there’s less chance of something to start leaking any time soon.


  • One-piece design
  • AquaPiston flushing technology (1.28 GPF)
  • Comfort height


  • Above average price

4. TOTO CST743S#51 Drake

The Toto’s Drake is a series of toilets that are getting upgraded every once in a while. The CST743S#51 is one of the older toilets from the series and it doesn’t feature the latest Toto’s goodies such as the Double cyclone flushing system. However, we believe that it’s still a great buy for average consumers who don’t want to break the bank with buying a new toilet.


The downside of the Drake II is the round bowl which doesn’t offer as much comfort as an elongated bowl. Round bowls usually make the toilet a little bit shorter and more appropriate for smaller bathrooms, but the Drake is about the same length as the Kohler Wellworth which has an elongated bowl.

Flushing system

The Drake comes with G-Max flushing system. It has a few of the same features as the Toto’s Double cyclone system, but the Double cyclone provides a better rim wash. The G-Max uses 1.6 gallons of water per flush which means that it’s still efficient enough for most consumers.


  • Contemporary design
  • G-Max flushing system (1.6 GPF)


  • Round bowl

5. KOHLER K-4007-7 San Souci

The last toilet on our list is the K-4007-7 San Souci, a futuristic looking toilet with low-profile design. It’s available in several colors and it features Kohler’s AquaPiston flushing system that uses 1.28 gallons of water per flush.


The San Souci looks very sleek and futuristic. It’s one of those toilets that you either love it or hate it. We believe that it looks great, but there are probably many people who disagree with us.

The tank is very short and it blends with the rest of the toilet nicely through one-piece design, making it look smaller than it actually is.


  • Unique low profile design
  • AquaPiston flushing system (1.28 GPF)


  • Its unique degisn might be a turnoff for many consumers
Buyer's Guide

Why would you buy a black toilet?

The main reason why black toilets are getting more and more popular each day is the fact that many homeowners have become fed up with traditional designs. White toilets and other bathroom fixtures can certainly look great, but many homeowners find them boring.

Design freaks are always on the hunt for something new and exotic and black toilets can be a powerful breath of fresh air. They can make your bathroom look contemporary, stylish and invigorating at the same time, as long as it matches with the style of other fixtures.

White vs. black toilet – pros and cons

Black toilets don’t have any advantages over white ones other than the looks. The design is a matter of personal preference, so it’s impossible to say which color is the most appropriate for toilets.

When it comes to disadvantages, black toilets have a few of them that are impossible to overlook.

There’s a saying in the plumbing industry circles that says “You never know how dusty can a toilet get until you buy a black one”.

When it comes to maintenance and cleaning, black toilets require more of it. The transparent mineral buildups on the surface of the bowl are much easier to spot on the black surface which means that black bowls require more cleaning to look clean.

Another thing that stands out more on the black surface is dust. Toilets become dusty very quickly and while dust is not easy to spot on white surface, it’s much easier to spot it on black surface. 

Another downside is that if you are just replacing your old toilet with a new one and you have chosen the black design, you will probably need to redesign things around it so black toilet won’t look like an outcast.


No, but they need to be cleaned more frequently because the dust is more visible on dark surfaces.

Yes. We analyzed over a hundred of different toilets that are available in several designs and we found that black toilets are usually 5 to 10% more expensive than traditional white ones.
