We're not all lucky enough to have those sprawling, spacious bathrooms, but finding the best toilets for small bathrooms or your powder room can be just as challenging. But don’t you despair! An in-depth review of the best compact toilets for a small space and buying guide with ingenious solutions is just what you need.

A smaller bathroom is exactly where the best small toilets fit the bill. Here we look at the best compact toilets for small bathrooms, ranging from convenient heights to slow-close toilet lid designs that are meant to increase the comfort of the one who's using the toilet. Of course, as you're planning for a toilet upgrade or installation, the first thing you should do is to talk to your local authority and get a building code for the area you live in.

There's standardization in many of these requirements; however, some regions may vary. General guidelines on the minimum space required for composting toilets:

  • A minimum of 30 inches distance from the left to right
  • A minimum of 21 inches distance from front to back, which includes the length of your toilet. However, 24 inches is more preferrable

Other considerations to keep in mind for the best compact toilet include where the door is and how it opens and closes, where the sink is in relation to the toilet, and how large it is. These are the clear zones. Small space configuration with tight corners take real skill and a keen eye.

Galba ranks high as the best compact toilet. A durable toilet with clean lines and a simple design that works equally well with modern and traditional bathrooms. It comes in one color, white, and has a concealed trapway for both style and hygiene.

At 24.5 inches deep, it gives you an extra half an inch of space, which may not sound like much, but as you're working with a tiny room, every little inch counts. That half-inch could very well be the difference between having your knees jammed or free against your bathroom door.

It is a shallow toilet with a shallow depth that is achieved using a very narrow toilet tank to make sure there’s no compromise on the bowl size. Comparably, it has a more substantial seat and seat cover and is made of UF plastic that is easy to disconnect if you do decide that you prefer something different.

Its Vortex Vormax flushing system produces plenty of power for a power flush to leave your bowl clean, while its dual flushing options help save water. A heavy flush uses 1.6 gallons per flush, while a half flush uses roughly just half of that. In addition, its glazed surface is self-cleaning, won’t stain, fade and is scratch resistant.

There are some things you need to be aware of, though. The major difference between this toilet and the others, however, is its price. Additionally, some users point out instances where the spring mechanism for its flush popped out, which is easy to pop back in, but it's not something you'd expect from such an expensive toilet.

Also, make sure to have at least a 12-inch rough-in space, or this toilet won’t fit. But, overall, it is a pretty great toilet if you’re willing and able to pay its price.


  • It is a one-piece design
  • It has a self-cleaning glazed surface that doesn't scratch, discolor, rust, or fade
  • It uses a dual Siphonic flush with a cUPC and MaP flush score of 300
  • It has a height of 16.5" as a Comfort Height toilet and an ADA compliant toilet
  • It has a slow closing seat that is included in the package
  • It is an excellent space saver with a depth of 24.5 inches for a very shallow profile
  • It is highly efficient in its dual flush, which helps save water
  • It uses a Vortex Vormax flushing power that enables it to function efficiently even while using a slimline tank


  • Its spring mechanism is prone to popping out
  • You’ll need hefty deep pockets for the Galba toilet
  • It comes with 12-inch rough-ins, so if you get it wrong, you'll not only have to pay for the return fee but also a 10% restocking fee

The Kohler Santa Rosa has such outstanding features making it one of the best toilets for a small bathroom, saving plenty of space. An elongated bowl that complements its compact build as a narrow bowl toilet seat remains quite comfortable.

Thanks to its quiet close technology, the toilet seat goes down slowly and quietly, with easy installation. Moreover, unlike other compact toilets, the Kohler K-3999-0 can be both assembled and set up in only 2 hours.


  • It has a comfort height elongated toilet bowl that makes sitting down and standing up much easier for older adults or people with mobility issues

  • It is a water conservation toilet that meets the strict EPA flushing guidelines, such as using at least 20% less water than the regular 1.6-gallon toilets

Its installation process is pretty simple and needs a 12-inch rough-in from your wall to the outlet.

Factors to Consider When Buying The Best Toilets for Small Bathrooms

 A) Your Space

Yes, you need a compact toilet, but again just how compact do you need it to be? Or maybe you have a shallow room, and you're trying to avoid knees from pressing against the door as you use the washrooms. Alternatively, you may be trying to fit in a toilet alongside your bathtub and probably need a narrow unit so it won’t seem all cramped up.

A compact toilet doesn’t come as one standard-sized toilet. You'll need to measure your floor space to help you decide what toilet will fit. Also consider, marking out the dimensions of the preferred toilet using tape on your floor. This will give a much better idea of how your small toilet will look when it’s finally in place since you don’t want just to save space; you also want it to look good.

B) Work Within Your Budget

Like other items, you want to set a budget that gives you the parameters you ought to work within. Unfortunately, most compact toilets will vary in price, so you can easily get carried away and blow up your money.

C) Conservation

Toilets can vary to a surprising degree in the amount of water they will use to flash. So choose a water-efficient toilet will save you both on your water bills and in saving the environment.

A dual flush system is particularly good because it allows you to use different amounts of water depending on whether you want to dispose of solid waste or a light flush for liquid waste.

D) Style and Functionality

As much as the toilet needs to be functional, the toilet also needs to look good. It's going to be a permanent fitting in your everyday life and something you will have to look at every day. So even toilets should come with good aesthetics and sleek designs.

A traditional small bathroom will do well in a two-piece compact toilet, whereas if you're going more for the modern look, a one-piece toilet will better complement your bathroom. A wall-mounted toilet also suits up-to-date styling too.

Frequently Asked Questions on The Best Toilets for Small Bathrooms

1. Why should I get a comfort height toilet?

A comfort height toilet is raised to make it more comfortable for the user. It is particularly helpful for the elderly and people living with mobility issues. It is much easier to get on and off, thanks to its 17 to 19-inch height.

2. One-piece Vs. two-piece toilet?

Getting a one-piece or two-piece toilet is really up to personal preference. A one-piece compact toilet has a more modern look and has less height but may be slightly wider than the two-piece. On the other hand, a two-piece comes with a greater height but may actually be suited better to narrow spaces.

If you want a more traditional/conventional look in your bathroom space, then you should consider choosing a two-piece toilet and vice versa if you want a more modern look.
