Best Compact Toilet – Grand Solution for Small Spaces (Spring 2022)

TOTO is a premier brand in the industry producing one and two-piece compact toilets along with gravity fed to pressure assisted toilets. The MS853113E also known as the Ultramax Toilet, is a one-piece toilet that provides a powerful flush without the noise.

Its highlights are E-max flushing system and WaterSense certification. The E-Max flushing system delivers a powerful and consistent flush using a wide 3 inches valve along with a rather large siphon jet. This gives this toilet an incredibly rapid flush response. 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.

This unit falls in the higher price category but given all its benefits, is totally worth the investment. That is also why it makes our Editor’s Pick.

Its aesthetics are top-class featuring chrome hinges and a sleek design that impresses the eye. It is a one-piece unit that comes with no the external tank and functions with a timed button. This toilet may be tricky to install, but the result is totally worth it.

After an approximate 10-15 seconds, the motor stops and the timer program refills the bowl with fresh water.

This feature gives this model a high efficiency cleaning system which makes maintenance that much easier. Yet it uses a minimal amount of water but with the same efficiency of a standard toilet.

However, it doesn’t mean that this unit scrimps on any of the essential features. If anything, it has quite a few surprises in store for you.

This mechanism is power packed and minimizes waste buildup while keeping the toilet bowl clean.

Its design profile features a one-piece skirted unit that is easy to keep clean – it has flat surfaces and a quick release detachable seat, while its self-cleaning glazed surface prevents skid marks and gives a cleaner flush. The same also prevents the unit from changing color, rusting or scratching. The one downside may be the low level of water in the bowl, which means you may have to clean the unit more often.

The manufacturers have paid special attention to its engineering and created a very durable unit that can bear heavy weight well. This unit is accessorized with a slow closing seat which saves you the trouble of buying one separately.

And today we will talk about their two-piece H2Option which rounded shape saves you those few essential inches of bathroom flooring in a small area. This toilet is WaterSense certified, meaning it yields exceptional low water consumption that translates into a lower water bill. The partial flush feature further economizes your water consumption but doesn’t cut down on efficiency.

This model has a pressurized rim that lets water be sprayed into the toilet automatically. This feature scours the bowl to ensure that it stays fresh. The PowerWash rim and siphon jet push any bacterial residue off the bowl’s surface which is a meaningful function for anyone who wants to enjoy an exceptionally hygienic bathroom without having to put in too much elbow grease themselves. Plus, there is an EverClean surface that keeps the unit cleaned reducing the need for manual cleaning.

Installation is easy for anyone who knows what they are doing with a standard 12 inch rough-in to the waste pipe. While installation requirements are similar to other two-piece toilets this one comes with the grommets and bolts pre-installed. The pre-assembled loose parts are a much appreciated time saving part of the installation process.

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

What is not ideal about it?

• Tight side latches

A compact portable toilet is a great thing to take along on your travels. But when you have an RV you can consider the next best option – a toilet that will hook up to the central water tank of your vehicle with a waste tank located beneath the floor. And the Aqua Magic V fits the bill.

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.

So every time you flush the unit, it cleans all parts of the bowl, targeting even the most difficult spots. The toilet comes with a textured lid that sheds water and resists scruff to keep a clean surface.

Although it is a plastic construction, consumers are satisfied with its reliable performance on their travels.

If you’re trying to save space by wall mounting your unit, then this next product is for you. This modern toilet doesn’t need a water tank to clear the bowl’s contents but is designed to receive water directly from the supply line at a higher pressure.
