1. Saniflo Sanicompact 023

First stop: The Saniflo 023 Sanicompact.

We've talked about this in our best overall toilets guide, but it's definitely one of the greatest space saving toilets out there. Not only is it petite, it can also fit into any narrow space!

Look how petite it is: 18.2 x 14.5 x 15.8 inches with the water tank built inside. What’s unique about this design is that the toilet is electrical- meaning the flushing mechanism is all electrical.

It can be placed anywhere from 9’ - 20’ away from the main waste drain pipe. It uses a macerating system that chops all the waste into a slurry, that is then pumped through a 1” pipe to the waste drain.

Also, the flush is triggered by a button, so you can choose either 1 gallon or 1.28 gallons per flush.

What We Like:

  • Compact Design
  • Water efficient - 1 GPF
  • Easy to install

2. TOTO Aquia

​Second stop: TOTO Aquia.

I love TOTO. The four letters synonym for the word "quality."

With 27.5 x 14.2 x 31.2 inches as its dimensions, TOTO Aquia performs outstandingly in terms of space saving.

This toilet is equipped with a unique weapon: the dual flush. This feature gives you two options of flush: 0.9 GPF light flush or 1.6 GPF heavy flush. You will be amazed by how much water is saved simply by adding this feature to your toilet.

What We Like:

  • Low water consumption - WaterSense certified
  • Dual-max flushing system (0.9 and 1.6 GPF)
  • Easy to install

3. Galba

Here I present to you the GALBA 24.5" 24" 25" Inch Small Toilet, the space saver.

It feels like a normal fully sized toilet, but in actuality, it’s great for small bathrooms.

It's a one-piece toilet, which makes it very easy to clean, especially on the exterior surface.

Flushing power is very adequate and it's very water efficient too as it has the dual flush mechanism - 0.8 GPF light flush and 1.6 GPF heavy flush. It will make sure your number twos are gone for good.

It comes with a soft-close toilet seat which gives it a very nice touch. Don't worry, it's unbelievably comfortable. Installation is fairly easy, so once it's in, it's solid.

Installation is just like any other toilet and conceals all the screws nicely. However, if you want to take the easy way out, just get a plumber to do it all for you.

Small Toilets: What To Look For

Hitchhiking through galaxy may be a great pain in the ass, but hey, no one tells you to do that.

When picking a small toilet, there are a few factors to consider:

A typical toilet’s dimensions are around 27' 1/2” D x 18' 3/4” W x 26” H.

Needless to say, a "small" toilet should be smaller than these dimensions, but here comes the tricky question. How small should a small toilet be and do they compromise functionality with size?

So far, the smallest toilet I’ve found is 14 x 24.5 x 27 inch and functionality is still there. So, finding an ADA standard compact toilet isn't an impossible thing.

Just like a normal toilet, a small toilet has the power to flush down a horse.

Nowadays, the American federation requires toilets to use less than 1.6 gallons per flush to achieve maximum flushing power. Under these circumstances, the small toilets we're looking for must be equal or less than this while still maintaining adequate performance.

The standard toilet has a rough-in length of 12 inches. This is why the toilets we look for must have this rough-in length, but don't worry, all our toilets meet this.

Yes, this can make a big difference in terms of size. Generally speaking, one piece toilets are smaller than two piece toilets, because they come in one big unit, unlike two-piece toilets that comes with the water tank and bowl attached separately.

And The Winner Is...

Being a star lord isn’t a very promising job. I’ve lived in various houses in my years, especially in my youth. At one point I didn’t even have a bathroom! So, a small bathroom is better than nothing.

BUT, you can always brighten up your small bathroom and a compact toilet is one of the main features to liven up the place. So after searching every different kinds in the galaxy, I've found it...
