10. Aqua-Magic Thetford 31667

I know what you’re thinking, “Come on now Tim, I give you a chance, and this is what you show me. Where does this freak come from?”

Relax, this is not a normal toilet that you put in your bathroom. Instead, this is a portable toilet. It fits best in an RV.

Aqua-Magic offers different models, from pedal to hand flush, either of it is a good choice. The size of this thing is small and it only weighs 7.4 pounds. 

The obvious problem is that it requires a water supply hose to flush. Also, the whole toilet is made of plastic so it can give off the “cheap” vibe. However, it is probably one of the best portable toilets in the market.

What We Like:

  • Portable toilet
  • Light
  • 100% bowl coverage flush

What We Don't Like:

  • Installation
  • Cheap look

9. WoodBridge T-0008 Luxury Bidet Toilet

The great thing about this model is that you can buy a bidet toilet for the price of a regular one-piece toilet. It comes with the functions like a water heater, warm air dryer, unlimited warm water, heated, on/off sensor, self-cleaning nozzles.... There are way too many functions in this toilet.

This toilet weighs 134 lbs, which can cause a bit problem during installation.

From my personal experience, there is some downside to this model. The button design can cause some product to stuck and thus creating a huge pond; however, this is not a typical thing. Another major problem will be the flushing power.

Oh, damn, WoodBridge comes with a 2-year warranty on the bidet.

Honestly, it is a bit weak like those water-saving toilets. It may produce a bit inconvenience but doesn’t affect the performance of this toilet.

Wood Bridge is a mystical toilet company, but they certainly can make an amazing toilet, so who cares? 

What We Like:

  • Seat and bidet included
  • Comfort height
  • WaterSense
  • Adjustable Water Pressure
  • Hygienic Filtered Water
  • Water Heater
  • Heated Seat (5 adjustable temperature)
  • 2-year warranty for the bidet

What We Don't Like:

  • Small flaw in button design
  • Shipping issue
  • Difficult to install
  • Flush is a bit weak

8. Toto Aquia Wall-Hung Dual-Flush Toilet

Mounted toilets are a big thing in one-piece toilet category. And of course, TOTO Aquia is a fantastic wall hung toilet among all. Coming with an amazing dual-flush system, the toilet uses 1.6 and 0.9 gallons per flush. Also, this model is glazed with Sanagloss all over, so cleaning should not be a problem.

The Bad thing though is that the seat and the tank are sold separately. And as a wall-mounted toilet, the installation is always a bit complicated. Most people favor putting the tank behind the wall. I usually open a small window so it will be easier to make the future adjustment.

What We Like:

  • Dual-flush
  • Sanagloss
  • Universal height

What We Don't Like:

  • Seat is not included
  • Tank is not included
  • Installation

7. HOROW Small Toilet w/ Dual Flush 

Horow is a China brand. Maybe that’s why they produce toilets at such a cheap price. But, it doesn’t mean the quality is not good. After all, Horow spreads its seed across the great land of China.

This model uses 1.6/1 gallon per flush with the dual-flush system. The dimensions of the toilet are 25'' X 13.4'' X 28.3''. Beware that this toilet is smaller than normal toilets, so double check your bathroom before jumping into action. The rough-in is 12 inches.

What We Like:

  • Glazed surface
  • Installation
  • Soft close toilet seat
  • Small

6. TOTO Neorest

I love crazy high-tech toilets. TOTO happens to be the company that produces these amazing toilets. Neorest will be the best out of all. The best part of Neorest is that the water cost per flush is only 0.8/1 gallon. Can you believe that? 1 gallon per flush! And the flushing power is also strong enough. It'll leave no marks in the bowl even when using only 1 gallon of water.

Neorest inevitably comes with some crazy features, like auto lid open/close, auto flush, heated water, warm toilet seat, butt wash… you name it.

TOTO offers a 3-year warranty over Neorest toilet, so there’s virtually no risk in purchasing this. And the installation of this toilet is super easy.

What We Like:

  • WaterSense
  • Crazy bidet functions
  • 3-year warranty

What We Don't Like:

  • Pricey

5. Woodbridgebath T-0019 w/ Soft Closing Seat

As I mentioned in the article, a good toilet only needs three things, good flush, good looks, and a comfortable seat. Obviously, this model has it all, but other toilets also have the same function, so how does this one stand out?

The first thing is the sleek style that compliment with lots of bathroom design.

The second will be the silent flush. It is so powerful and can kill anything you dump into the bowl. Also, the toilet has the Water Sense label, so the water usage is eco-friendly.

Last but not least, it is super easy to install, and a quite-close toilet is included when you purchase this toilet.

With the dual-flush system, the water usage is 1.0/1.6 gallon per flush, resulting average 1.28 gallon per flush.

What We Like:

  • Easy-to-Clean Design
  • Dual Flush System Design
  • Comfort Height Design
  • High-end Soft Closing Seat with Stainless Steel Durable Seat Hinge
  • 5-year warranty

What We Don't Like:

  • Flushing power
  • Heavy
  • Installation

4. Swiss Madison Square Toilet

Oh, yeah, it’s a square toilet. Finally something exciting. Although most people like the elongated shape of toilets, sometimes my clients force me to show another option. And here you go.

Swiss Madison offers a sleek outlook and a unique design. Personally, I think it looks way better than the Duravit.

Another cool feature of this toilet is that the toilet seat isn’t bolted to the bowl, so it is super easy to remove. Thus you can save a lot of time cleaning the toilet. Also, the seat is soft-close.

The water usage is quite normal, 0.8 and 1.28 gallon per flush, and the flushing power is also very nice.

The dimensions of this toilet are 27 x 14.3 x 29.5 inches, and it weighs 104 pounds. Small and cute.

What We Like:

  • Dual-flush
  • Comfort height
  • Soft close seat
  • Easy seat removal

3. Saniflo 023 SANICOMPACT 48

Ok, don’t be scared by the price tag. This cutie has the high price for a reason.

Saniflo is a sanitary ware company that is famous for making up flush toilets, A.K.A super strong flushing toilet. Usually the Saniflo toilets are quite big; however, Sanicompact does the exact opposite. Its size is super tiny and can save you a lot of space.

And how can a Saniflo toilet be a Saniflo toilet without having the upflush ability? Sanicompact can flush your feces up 9-feet vertically and 100-feet horizontally, so if you want to have a bathroom under your pipeline or in a loft/attic, then this is your number one choice.

What’s more impressive is that Sanicompact only uses 1 gallon of water when flushing.

From what I’ve tested, this toilet is easy to install like any other toilet, and it fits small bathroom quite well.

What We Like:

  • Tiny
  • Upflush system
  • Able to connection to sink
  • Use 1 Gallon per flush
  • Cool design

What We Don't Like:

  • Quality issue

2. GALBA Small Toilet

GALBA kills it on this toilet. The best feature of this toilet is that is it is so small that it can fit even in the tiny powder room. I’ve dealt with this model of toilet many times, and all I can tell you is that GALBAs' toilet does hit all my criteria for a toilet.

With the dual-flush system, GALBA uses 0.8 or 1.6 gallons per one flush. From my experience, the flushing power is sufficient to wash down those nasty masks. Speaking of dirty marks, GALBA small toilet has a glazed surface like most of the modern toilet, so it is hard to get dirty or crack. The only thing that I find quite amusing is that there is a Galba logo on the tank (see how they pride their product).

The toilet is smaller than a normal model, and thus it can save tons of saving in a small bathroom.

There are two problems I faced when I was installing one of this toilet in my client’s project. One was the tank lid wobbles a little, and the other was the toilet seat moved even when I tightened the seat. However, the customer service of this company was extremely helpful and gave me some amazing tips.

What We Like:

  • Self-cleaning glazed surface
  • Dual flush - 0.8/1.6
  • Soft-close toilet seat
  • Great customer support

What We Don't Like:

  • The lid may rock a bit
  • There is a logo on the tank

1. American Standard Champion-4

Once I watched the Champion-4 flushes down tons of golf balls video, I was convinced that Champion-4 is the strongest flushing toilet. If you’re the type of person that get annoyed with marks on your toilet, then the flushing power of this beauty will not let you down.  

The best part of this toilet is that comes with a 10-year warranty on this model. 10 YEARS!

Furthermore, it is made in American, which means quality. But most importantly, this toilet doesn't clog or leak water, which in my opinion is what a great toilet should be. 


What We Like:

  • ADA height
  • Super strong flush
  • WaterSense
  • EverClean surface

What We Don't Like:

  • Water usage

What Is One-Piece Toilet?

If the toilet and tank are fused together without any joints, then the toilet is known as one piece toilet. It is also known as single piece toilet.

If the toilet and tank are separate and joined using fittings, then it is known as the two-piece toilet. It is also called as coupled toilets.

One-Piece Toilet Advantages

I was bothered by this question for a while, and even wrote a post talking about the difference between the two and one piece toilet types. Since one-piece toilet has almost identical functions with two-piece toilet, then why should customers choose a one-piece instead of a two-piece toilet? Especially when the price of a one-piece toilet is generally higher than a two-piece toilet.

Ok, let us understand how one-piece toilet came to the world. In 1885, Thomas Twyford built the first one-piece toilet; however, neither design or function were nowhere near modern toilets. It already had the U-shape trap design, but the tank was hung high on the wall like a pull-chain toilet.

Fast forward to now. One-piece toilets have these amazing functions:

  • check
    Easier to install - due to its one-piece design, the owner or the plumber doesn’t need to tighten the tank to the bowl anymore.
  • check
    Small on size - To be honest, the one piece toilet can only save you a few inches; however, if you pick the wall hung model, the tankless design can save you tons of space.
  • check
    Easier to clean - Without the crevice or the joint between the water tank and bowl, the one piece toilets are way easier to clean compared to a two-piece toilet.
  • check
    Less maintenance - It is because the single piece toilet’s tank and bowl are fused together, so there’s less chance to break down.
  • check
    Less shipping problem - I know this may come as a surprise to many people. Common sense is that closed-up toilet is usually heavier compared to a two-piece toilet. However, the plus side of this kind of toilet is that it is shipped as a whole product. Unlike a two-piece toilet that needed to be sent separately, and often time causes a lot of problem along the way.
  • check
    Comfort height - Usually, the bowl sit is at 17 inches than 15 inches

But of course, a coin has two side. The disadvantages include:

  • check
    Price
  • check
    Heavy
