10 Best Compact Toilets for Small Spaces

Last Updated: April 03, 2021


Though some people dream of bathrooms with toilets that have an integrated bidet or some other great features, you may not have as much room as those people do. Even if you have a powder room tucked beneath the stairs or a tiny bathroom that you share with one or more other people, you’ll still find a compact model that fits the space and has some good features.

The top model that we found is the San Souci from KOHLER (Check Price on Amazon.com), which has an almost pedestal design. It has a solid base with open spaces on the sides to further reduce the space it needs and a lower profile with a small and rounded bowl on the front. This model features a bowl with a canister design that helps the water reach all areas inside the bowl.

How to Choose the Right One?

How Much Space Do You Have Available?

Not all of these products are as small as the next, which is why you need to look at how much space you have available and pick one that fits in the room. You need to consider both the width the depth of the bowl as well as the height of the bowl. It’s important to factor in the overall height of the tank too.

What Type of Bowl is Best?

The right bowl will save you some extra space and make you feel extra comfortable too. You might like a rounded bowl that sits closer to the tank and extends out less in front. An elongated bowl has more room for you to sit but also takes up more space.

Is a Corner Model a Good Choice?

To save space in a tiny bathroom, a corner model can help. These models have a triangular tank that fits tightly in a corner and sits flush with those two walls. This lets more of the tank remain tucked in an out of the way space and reduces the space that the entire piece needs.

Before choosing a corner product though, you need to find out if your bathroom can accommodate way. The placement and type of plumbing that you have may not work with this model. You may need to more some pipes to support the product.

What Type of Handle Do You Need?

You can choose between models that use one of two handle types. Many come with a classic handle that looks like a lever. This lever connects to the valve inside the tank via a chain, and when you press the handle down, the chain lifts up the valve to let water leave.

Newer and more modern options come with a push button that acts like a handle. Others have two buttons that sit side by side. One button uses a lower flow of water, and the other button uses more water to flush.

Will a Mounted Model Work?

In addition to standard models, you may want to use a mounted product to save even more space. These models work with tanks that you install inside the wall. As the bowl extends out from the wall by just two feet or less, you’ll have more usable floor space in the room.

Top Compact Toilets on the Market

KOHLER San Souci

The San Socui will work in a powder room or any full bathroom where you have less space because it has a low profile that puts it closer to the ground and a smaller bowl that still eliminates waste quickly. It features a canister design that reduces the space inside the bowl. This also allows any water that flows through to rush and circle around the bowl to remove more waste than ever before.

A round bowl on the base is just the right size for sitting down and supporting yourself while using the bathroom. Though this bowl is on the small side, it still offers plenty of room for you and users of different sizes.KOHLER K-4007-0 San Souci

Has a lower profile

Must have a 12-inch rough-in


One of the smallest and most compact models on the market is this one from GALBA, which features both a shorter seat as well as a shorter overall height. It has a soft white finish with a button on the top of the lid that acts like the flushing handles found on other products. This model also uses just one piece to reduce your overall installation time.

A top feature on this model is the glaze that is resistant to scratches. This is also a self-cleaning glaze, which means that it will use the water that comes out when you flush to clean itself and remove bacteria from the bowl.GALBA SMALL 24.5


Has both a shorter overall height and a shorter seat height
Made from one piece for easier installation
Surface glaze is resistant to scratches


Only works with a rough-in of at least 11.5 inches

American Standard 216AD

American Standard makes a number of affordable options for your bathroom like this one, which comes with its patented Power Wash system. That system increases the number of holes around the rim and allows more water to come out with each flush to remove any of the debris stuck to the sides. It still uses just 1.6 gallons though to reduce your water bills.

Designed for use in a bathroom corner, this product has a triangular shaped tank that fits into a tight space, but the base extends out slightly. Though it uses less space, this model provides all the comfort that you need.American Standard 216AD004.020

KOHLER Persuade

The Persuade comes with a dependable warranty from KOHLER that helps you get help with both the original installation and any problems that might come about later. That’s important because this toilet may leak when it does not sit properly on the floor. It features a button that works as part of a dual flushing system to use just as much water as you need.

A trapway located inside is a little larger in size and has a skirt surrounding the sides to prevent clogs. As it uses a separate tank and bowl, this model is easier to repair and to install. This product also works with some of the different seats made by KOHLER.Kohler K-3654-0 Persuade

This lets you use 0.9 gallons or a full 1.6 gallons to remove waste from the bowl, though you may find that the smaller option doesn’t always remove all that waste. The button has a convenient location right on the top of the tank.

A skirt that wraps around the base gives it a more elegant look and hides all the components inside that base. It comes with a base and a tank that each ship in a separate box, which makes it easier to carry the whole thing inside your home and set it up in your bathroom.TOTO CST412MF.01 Aquia

American Standard Cadet-3

Its EverClean system is resistant to both mold and mildew as well as common types of germs and bacteria.

As a right height model, it is safe for use in any ADA bathroom, but it’s also tall enough that you can sit down without feeling any pain. The elongated bowl found on this product has a longer and deeper size but takes up the same amount of space as a round bowl would. It also has WaterSense certification too.American Standard 2403.128.020

Renovator's Supply Round Corner

One of the best ways to save space and make your bathroom look larger is with a product that you can install right in a corner like this one. Renovator’s Supply designed this one to measure just 18.5 inches across the top, which lets it take up even less space when tucked inside a corner. The manufacturer also added a finish to the china that is resistant to both stains and scratches.

This corner model is also one of the dual flush models that has one button for using a low or an ultra low setting. The low setting uses 1.6 gallons and is suitable for more solid waste. Its ultra low setting uses only 0.8 gallons per flush but is strong enough for any type of liquid waste.Renovator's Supply

Though its name makes it sound like something from an action flick, the T-0001 is actually a strong product that is suitable for any home or bathroom. It has a modern design and uses just one piece that you can install easily, though you may have some trouble reaching the mounting flanges in the base. The trapaway in the base has a glaze coating that helps debris move down smoother to keep that debris from causing clogs.

Flush buttons on the side have clear number one and two markings that tell you which ones are suitable for solid and liquid waste types. Each button produces a different amount of water to work on that waste.WoodBridge T-0001 Dual Flush

Built into the base is a trapway that is slightly larger in size to allow more waste and debris to move down the pipe without clogging the base. This model is resistant to scratches caused by paper and other things that you flush. Its finish is also resistant to stains.White Porcelain Round Space

Our Winner Is...

KOHLER K-4007-0 San Souci

Save space and water with the San Souci, which has a round front that takes up much less space than an elongated front would.

It also has a lower profile that you can hide behind a sink or cabinet.

Despite being a smaller model, you’ll still get all the space that you need for sitting. The back of the base is slightly open to further reduce the footprint and to give you space for storing things around the base or using a shelf above.
