The 5 Best Compact Toilet For Your Small Bathroom

Are you looking to upgrade your RV’s washroom facilities? Struggling to find space for a regular toilet inside a tiny bathroom? The solution to the problem in both cases is a compact toilet.

Wait, a compact toilet, what exactly is that?

Basically, a compact toilet is like a regular toilet, but smaller. Unlike a normal-sized toilet, it is designed specifically for bathrooms, powder rooms, and en-suites with limited space to work with.

Is it any different from a normal toilet?

Yes and No. A compact toilet works just like any other toilet, but because it is smaller, it has some unique features. Fully shrouded bowls, shorter bowls, hidden tanks all are features you’d expect to see in a compact toilet, but not necessarily in a normal toilet.

Ultimately, they are a better fit for small bathrooms, and though their main advantage is that they are excellent space-savers, the best compact toilets in the industry come packed with a lot of handy features.

1. GALBA Compact Toilet with Elongated Bowl

At 24.5 inches long by 13.5 inches wide, GALBA compact toilet is definitely smaller than you’re used to. Nevertheless, most adults shouldn’t have any problems using this toilet, which is a one-piece, self-cleaning toilet with a glazed surface that is rustproof, scratch, and fade-resistant.

Its seat height is at a comfortable 16.5 inches from the floor, which both kids and adults can reach without issues, and for the rough-in, you’ll need a 12-inch clearance. The toilet comes with a G-Max Siphon Flush mechanism that offers dual flush functionality. A half-flush uses about 0.8 gallons of water, while a full flush consumes just 1.6 gallons.

2. Saniflo 023 SANICOMPACT Self-Contained Toilet

Some people might feel that the Saniflow 023 Self-Contained toilet is overpriced. However, when you consider that the toilet doesn’t have an external water tank, is extremely small, and uses precisely 1 gallon of water per flush, then you might reconsider.

The Saniflow 023 compact toilet flushes using an automatic macerating pump cycle activated by an air switch and electronically timed to allow only 1 gallon of water to pass through it on every flush.

What’s more, it is one of those nifty compact toilets that can be hooked up to a sink and can pump vertically for up to 9 feet and horizontally for up to 100 feet.

At 18.5 inches high, the toilet seat height is at that sweet spot, but its bowl, which measures 14.5 inches wide and 15.75 inches long, could be bigger. The manufacturers make up for it in the stylish design of the toilet, which features a porcelain build with stunning chrome hinges.


  • Very low water consumption
  • No water tank
  • Extremely compact


  • Perhaps a bit too small for everyone’s liking

Everything You Should Know Before Buying The Best Compact Toilet

Buying a compact toilet for the first time can be challenging if you don’t know what you’re looking for. Some may not live up to the hype, and you can easily miss out on some great deals if you don’t know the first thing about compact toilets.

Here’s a quick guide to remedy that, so before you begin your search, take some time to read through it.

Toilet Type

There are two types of compact toilets. The first is the two-piece toilet. This includes a separate toilet bowl and tank. Usually, this option is ideal if you don’t mind the slightly bulkier look, plus it is easier to replace one or the other unit if it breaks down.

The second type is the one-piece toilet. In such toilets, the bowl and the tank are fused together, making it look seamless and neat. The plus side of having such a toilet is that it is even smaller, and a little easier to install. On the downside, should one of the components fail, you may have to replace the entire thing.

Water Consumption

Fun fact, a regular toilet uses up to 7 times more water than a compact toilet. That fact isn’t very fun once the monthly water bill comes around. On average, compact toilets use around 1.5 gallons of water per flush, although this is on the higher end as well.

Pay attention to the GPF (gallon per flush) rating of the toilet you settle for. Some come with dual flushing systems that allow you to pick the half flush or the full flush to save on water whenever necessary. It makes a huge difference in terms of water consumption at the end of the month.

Flush Mechanism

Here’s where you need to get fussy. Compact toilets have various flushing mechanisms. You might hear the words “gravity flush” being thrown around a lot, and that’s because it is one of the best options out there.

The gravity flush uses water pressure to clear out the bowl through the tramway with the help of a siphoning action. This is quieter than the pressure-assisted toilet system that uses air to force down the water. Though this results in a faster flush, it is also quite noisy.

Lastly, there’s the dual flushing system, which allows you to save water by flushing partially or opting for a full flush.


Installing a two-piece toilet might be easier for some because it involves two separate units that are lighter individually. The same cannot be said about one-piece units, which tend to be heavier.

In the end, proper installation is crucial to prevent leaks like composting toilets and ensure the optimal flow of water. Remember, a one-piece installation is not always a one-man job, especially since these units can weigh quite a bit.

Shape and Size

If saving some space is what you’re going for, stick to units measuring 25 inches in length or less. Width and height considerations are almost always a personal choice, but ensure the toilet has enough rough-in clearance to allow for proper installation.

As for shape, you can save about 2 inches if you choose a compact bowl as opposed to an elongated one.

However, consider the level of thigh support you need, because shorter bowls may not always provide that.

There is, of course, the compact-elongated hybrid, which attempts to provide thigh support while still allowing you to save a little extra space.

Weight and Material

Most compact toilets are either made from porcelain (ceramic) or vitreous china. Vitreous china is known to be easier to clean, and thanks to a glazing technique, it looks shinier and denser.

On the other hand, porcelain is extremely durable, waterproof, and not so hard to clean either. In the end, it’s a choice between durability and aesthetics, and if you value one over the other, then you know what to go for.

Weight isn’t really an issue unless you’re springing for a portable toilet model. On average, a two-piece toilet weighs around 55 pounds, while a one-piece unit weighs about 33 pounds more.

Compact Toilets FAQ’s

Do I have to give up certain features in exchange for a smaller toilet?

Certainly not. In fact, choosing a compact toilet may give you features you wouldn’t normally get on a normal-sized toilet. Most compact toilets are more water-efficient as well as quieter when flushed.

Furthermore, some come with self-cleaning mechanisms that can be really handy in some instances.

How easy is it to clean a compact toilet?

Not any harder than it is to clean a normal toilet. In fact, some might say they’re easier to clean. Most are made from either porcelain or vitreous china, and the latter material even has antimicrobial properties.

Compact toilets can be cleaned with the same frequency as regular toilets.

Is it true that compact toilets are noisier than usual?

Not all of them are noisy, but those using air pressure to flush can be. It is all in the flushing mechanism, so pay attention to this before making a purchase.

Final Word – Which is the Best Compact Toilet for You?

With such a wide array of options out there, you really can’t be blamed for not knowing what to go for. Compact toilets are a great way to save space in cramped bathrooms. Some can be attached to sinks, which is an even better setup, while others don’t even have tanks they use water straight from the supply!

There are a lot of options out there, but only a few will truly give you the value you need. We’ve listed five of them here to make it easier for you to make a choice. Hopefully, you won’t need to come back here for a very long time after you’ve made your purchase, because the right compact toilet will suit you for years to come.
