Alongside the larger flushing valve, this model boasts a wide, fully glazed trap way, which minimizes any chances of blockage or choking.

This innovative technology is using a mere 1.28 gallons of water per flush every time. The WaterSense certification guarantees that water consumption is about 20% less than the amount of water flushed by using traditional toilets.

The TOTO Ultramax has a must-have soft closing seat that takes care of the bothersome toilet slam every time someone puts down the toilet seat. Its unique mechanism makes sure that the lid closes slowly and quietly – a real nerves’ saver in small apartments. The shape of the seat is designed to support the contours of the body, so you can sit for as long as you like without getting uncomfortable.

Instead of flushing away human waste, composting toilets use the natural processes of decomposition and evaporation to recycle it. The waste that enters the toilet is more than 90% water that gets evaporated and is returned to the atmosphere. The remaining solid materials gets converted to fertilizing soil through natural decomposition.

As such, a compact composting toilet must be able to do a number of things efficiently. For starters, it should compost the waste without odor. Then it should make sure that the compost is safe to handle. And finally, it should evaporate its liquid component.

The Nature’s Head model seems to do all this pretty effectively and without the smell of any compost byproduct either. The mechanism is that of dry composting where the toilet separates liquid waste into a different container.

The maintenance is quite easy – you just empty container with liquids once in two days, and it takes about 80 uses before you dispose of the solids. This toilet is surprisingly easy to clean with the usual toilet brush and some water.

This sturdily built unit requires easy assembly. Yet it is easy to transport and handle. But it would take some time before you learn to open the side latches smoothly.

Why did it make our list?

  • Big compost capacity
  • Easy disassembly
  • Portable
  • Eco friendly
  • Has a built-in fan
  • 5 year warranty

There are two height profiles available, and you can go for either the high or low based on you preference. The Aqua Magic V also comes with a foot flush or hand flush model and once again, you can choose which one you like better.

This recreational vehicle’s hand flush is user-friendly – when you activate it halfway, it adds water to the bowl, when you push it all the way, the flush gives complete coverage of the bowl.

Things to Consider

Tips on saving bathroom space for your house

Limited bathroom space may present a problem. Yet, you don’t have to compromise on either functionality or style of this living space as there are several ways to maximize it. To use every inch of you bathroom to its most try some of these tips:

  • Install a corner sink if that suits the layout better;
  • A narrow, wall-mounted trough sink gives more room for foot traffic;
  • You can connect sink right to your toilet, like Saniflo 023 SANICOMPACT;
  • Float the vanity to free up floor space underneath;
  • Accessorize the space over the toilet tank with a freestanding organizer shelf;
  • Don’t forget the space above your door – hang a shelf there for more storage space.

Compact and portable – toilet for your RV

Choosing a toilet for your RV as opposed to your home will obviously need some different considerations.

For the RV use, you can choose from different types based on what suits you best. Some options offer you a permanent fixture with a removable holding tank such as standard gravity flush toilet. Or you could go for a macerating flush where power-motored blades macerate waste before it goes into a holding tank.

Other options include a vacuum flush where contents get powerfully pulled from the toilet through a stored vacuum vessel and macerating pump into a holding tank. Another type engineered for recreational vehicles is the cassette toilet which provides a compact toilet bowl permanently attached over a small, removable waste tank.

The choice that’s right for you will depend on the size of your RV and the space available. Take a look at our Best for Travelling Aqua Magic V compact toilet to see how well it fits into your RV.

Need a tank?

It’s not that common, but not all toilets come with a tank. In fact, there is a tankless variety where the toilet receives its water directly from a supply line. The flushing mechanism for such models comes from the force of the water entering from the supply line.

So if you’re looking to save space and have the plumbing in place, the tankless toilet may be your perfect solution. We have one on our list, which is the TOTO 418F Aquia.

Choose wisely – important features of a compact toilet

All toilets share the same basic features but when you have limited space, you may need to be a little more vigilant in your choice of the best compact toilet. We have a detailed description of everything you need to consider.


In most cases, the width and height won’t cause issues and it’s the length, or front to back distance, that will be a deciding factor.

Because there are space clearance considerations in front of the toilet set, your best bet is to go with a shorter toilet. Shaving off those few inches to save more floor space is what you’re looking for. So go for a model that stays within the limit of 25 inches or less, length-wise, to choose from the most compact products available.

All those on our list today, save one, meet this requirement which gives you plenty of choices.

Type you need

Essentially, there are two types of constructions for toilets. The first is a two-piece toilet, which is also the most common type. With this construction, you get a product with a separate tank and bowl. Should any of the two parts need replacing, you can replace just the one that needs to go without touching the other.

In a one-piece toilet, the bowl and the tank are fused together. The benefits include a clean finish, and easier cleanup with no visible seams harboring any dust or grime.

On the space saving front, the one-piece comes out the clear winner as there is no need to make any provision to support the tank. However, the one downside to these models is that they do boast a bigger price tag than the two-piece toilets.

Space-saving shape

Toilets typically come with either compact or elongated bowls. While the width remains the same for both types, the length is what basically makes a toilet more compact. Compact sizes tend to be 2 inches shorter on average than those with elongated bowls.

In general, many people feel more comfortable on an elongated-style toilet bowl as there is more thigh support on the longer seat. So if you like the comfort of an elongated toilet bowl, but are short on space, then you can consider a hybrid known as the compact-elongated toilet.

This one-piece fits into the same space as the round front toilet, but with an elongated bowl. The GALBA MU133 model is a perfect example with well-rounded features.


In terms of materials, there is a choice between porcelain/ceramic and vitreous china for the bowl.

Of these, porcelain/ceramic is a very durable and reliable material and is cheap to manufacture. It is water-proof, easy to clean, and will support even the heaviest of users without giving way.

Vitreous china is a glazing technique added to the porcelain which makes it denser and shinier.

Water consumption for better economy

Toilet water use can vary quite a bit. So much so that older toilets may be using up to 3, 5, or even 7 gallons of water with every flush.

Water economy

Nevertheless, newer, high efficiency toilets only use up to a max of 1.28 gpf (gallons per flush) of water like TOTO MS853113E Eco Ultramax. This helps conserve water and all of the models listed as our recommendations fall in this category. Low flow models use only up to 1.6 gpf.

Flush type

There are quite a few different types of flushing systems. Among popular choices, you will find the gravity flush system that uses water to create flushing pressure. This, in turn, forces everything from the tank and bowl through the trapway. A siphoning action completes the flush and cleanses the bowl.

A more contemporary take on flushing systems is the pressure assisted system that uses pressurized air to force the water down. This system will get the water down faster than the traditional gravity system, but will also be louder.

For the environmentally conscious consumer, taking it a step further is the dual flushing system.  This gives you the choice to either go for a partial flush or a full flush. Saniflo 023 SANICOMPACT is a prime example of an efficient flushing system that doesn’t waste any water.


Standard two-piece toilets weighs around 55 pounds, whereas their one-piece counterparts can go up to 88 pounds. This is because the one-piece toilet holds the ceramic tanks and will definitely weigh more. If you are not looking for a portable unit, its weight won’t be an issue. However, Nature’s Head Self Contained Composting Toilet weighs about 28 pounds but is easy to disassemble for a convenient transportation.

Installation method

Even though one-piece toilets are much heavier to move around, their installation is much easier. There is no hassle of connecting the tank to the bowl and once you get the unit in position, the installation is almost done.

Installation for the two-piece toilet, on the other hand, is easier in the sense that you can deal with the tank and bowl separately. This allows you to split up the total weight between the two parts. The job is easier for a single person to handle as it eliminates the need to wrestle with a lot of weight.

That said, you need to be extremely accurate when mounting the tank to the wall to avoid leaks later on. So if you’re not too sure of your DIY skills, then just get some professional help instead.


As you’ve seen earlier, pressure assisted toilets to have a lot of efficient features but all that high octane power comes with a lot of noise. These models have noisy flushers, so if you want something quieter, then you could go with the more traditional gravity flushing system instead, like in TOTO MS853113E Eco Ultramax.

Another minor, yet somewhat bothersome consideration regarding noise is a slamming toilet lid. If you want to avoid the inconvenience of hearing a brick fall every time someone puts down the toilet lid, then look for a model with a slow-drop seat that closes gradually. Some toilets also feature slow-close seats that are removable, which can make cleaning a cinch.


Reputable brands will offer some kind of a warranty ranging from one year to a lifetime one. It could be a manufacturer’s warranty, a limited warranty on mechanical parts, a limited warranty on chinaware, or even a guarantee period for flushing systems, accessories and toilet seats. This will vary from one brand to the next, but you should always look for a warranty when you invest in a compact toilet.


It’s not surprising to find mold behind the toilet given its dark, damp location. To prevent this from happening, some common measures include regularly checking for leaks, having good ventilation and keeping humidity levels inside to a minimum. Regular cleaning of the area will also help this problem from worsening.

The functioning features of both types are very similar with size, with the length being the main difference. You can get all the functions of a standard sized toilet in its compact counterpart.

No they are not. You use the same cleaning techniques as you would with a standard toilet and as long as you do so on a regular basis, you should not have any problems.

Our Verdict

We think that our take on compact toilets has something for everyone.

The TOTO MS853113E Eco Ultramax can give you everything that you could wish for in a compact version of the standard toilet to give your small bathroom a stylish and functional touch. The only downside may be its price factor, so if you don’t like that then move on over to the Swiss Madison model.

The Swiss Madison SM-1T112, our budget pick, is also an absolute favorite as you can get the most out of the best toilet for small bathroom at a very reasonable price.

Ranking high among the best compact toilets, Saniflo 023 SANICOMPACT delivers well on looks and performance and won’t give you a lot to complain about. We really like that this model does not compromise anything given its significantly smaller size but adds to your bathroom’s appeal instead.
