Modern toilets come in different shapes, sizes, and levels of complexity with various seat shapes and height options to maximize comfort for a range of people. There are toilets with sleek one-piece designs that are easier to clean as well as high-tech toilets with auto-flushing mechanisms, heated seats, and even built-in deodorizers. Most new toilets feature low-flow designs, using at most 1.6 gallons per flush and in some cases less than a gallon, while composting toilets use no water at all.

In this guide, I used my own experience buying and installing new toilets for several bathroom renovations along with extensive research of more than two dozen models to make my picks for our list of some of the best toilets.

Whether a shopper is in need of a toilet for the home or requires a portable option for camping or RVing, there are many options available; it can be difficult to select the right one for your particular needs. Options for the best toilets overall depend upon type, size and shape, flush type, ease of installation, and other included special features.

The featured list of top picks prioritizes variety with one-piece bathroom toilets, two-piece toilets, bidet-toilet combos, composting toilets, and portable options included with gravity, pressure-assisted, hand-pumped, and dual-flush toilets to suit a user’s specific needs. The one- and two-piece options are favored for their gravity or dual pressure-assisted flush types, while the bidet-toilet combos include heated bidet seats, automatic lift and flush, and built-in deodorizers for those looking for high-end models.

For those who prefer eco-friendly options, the composting and portable models are hand pumped or use waterless flushing to consume little to no water.

A heated seat and an air dryer keep users warm while they sit. When the user has finished, the bidet cleanses with a gentle pulsating spray while the warm air gently dries.

Product Specs 

  • Type: 2-piece toilet
  • Bowl shape: Elongated
  • Flush type: Dual flush

Pros

  • Environmentally friendly for the eco-conscious consumer; dual-flush system helps save water
  • Taller design; ideal for taller individuals or those with limited mobility
  • Soft-close lid design is quiet and safer for homes with children
  • Accredited brand; approved by the Board of Registration of Plumbers

Cons

  • Height may be an issue for some users; recommended specifically for those who are tall or have mobility issues

For those with limited mobility, sitting on a 15-inch-high toilet can be a challenge, requiring users to descend and ascend to and from an uncomfortably low position. This extra-tall toilet raises the seat up to make sitting down more comfortable with a seat height that reaches 21 inches.

While pricier than other toilets, it will save money in the long run thanks to a dual-flush system that flushes at 1.28 gallons per flush for solids and just 0.9 gallons per flush for liquid waste.

A large ergonomic handle makes it easier to flush, while an elongated shape adds comfort and a soft-close lid prevents slamming. With its extra-tall height, this toilet is able to use gravity to a greater degree to create a more powerful flush.

Product Specs

  • Type: 1-piece toilet
  • Bowl shape: Elongated
  • Flush type: Dual pressure-assisted flush

Pros

  • Dual-flush design saves water for the eco-conscious consumer
  • Sleek, square design but with an elongated seat for comfort
  • Design looks great in modern bathrooms and matches most bathroom fixtures

Cons

  • Dark color can make it harder to see dirt and grime; more challenging to clean

This toilet makes quite a statement with its unorthodox shape and look. In addition to its black color, a bold departure from standard white, it also eschews the rounded shape we’ve come to expect from a toilet for a more angular look.

The tank and the bowl feature corners and flat surfaces, giving this model a cube shape. Don’t worry: This doesn’t mean the user’s posterior will have to conform to a square seat. The toilet seat features the traditional rounded interior circle, making it comfortable for the user’s rear end.

This sleek-looking toilet has a dual-flush design for water savings and a siphon for powerful flushes. A higher seat height of 17 inches adds comfort, while a soft-closing seat prevents accidental banging. For shoppers who favor a more traditional look, this toilet also comes in white.

Whether shoppers are living off the grid with no access to plumbing and sewers, or they’re just serious about going green, the Separett Villa 9215 AC/DC toilet is one of the best composting toilets a user can sit upon. The toilet separates solid and liquid waste, catching liquid in a drain that diverts it to a gray water tank. Solids go to a separate holding area with a compostable liner bag, which can be removed once full and taken to a compost area.

The toilet uses a fan that operates off an alternating-current or direct-current electrical connection to vent odors away from the toilet. This toilet mounts to a wall and features a comfortable oblong-shaped seat. With average family use, this composting toilet will generally require emptying every 3 weeks or so.

The waste tank is large enough for two adults to use full-time, which will require emptying every 4 to 6 weeks.

Ideal for camping, RV trips, and boating, this model features a seat and 2.5-gallon flush tank that sits atop a 5.3-gallon plastic basin.

The flush tank holds water used to flush the bowl via a hand pump. A pull handle flushes the waste from the bowl into the basin below, where it remains until users can dispose of it.

What to Consider When Choosing a Toilet

When deciding which new toilet to install in the bathroom, there are several factors savvy shoppers take into account, including what size the bathroom can accommodate, what shape will meet comfort demands, and how much water consumption a budget can tolerate. We tapped Mitch Cameron, general manager of Greensboro, North Carolina–based Go Green Plumbing, Heating, and Air, for guidance.

Brand

Brand can be an important part of selecting a toilet, as it can affect the ease of maintenance and potential repairs. While there are many budget-priced off-brand toilets you can choose from, Cameron suggests going with a known brand, such as American Standard, Kohler, or Glacier Bay. Doing so can make repairs easier when it’s time to replace parts down the road.

“When you go with the Kohlers and American Standards, most of The Home Depots and Lowe’s are going to have parts for it, whereas if you get a deal online on a no-name toilet, you won’t find parts for it when it comes time for repairs,” he says.

Type

When selecting a model, there are many types of toilets to choose from:

  • Two-piece toilets have a tank mounted to the toilet via two large bolts. These toilets are typically the least expensive and may require the lid to be purchased separately.
  • One-piece toilets offer a sleeker look with the toilet and tank consisting of a solitary piece. These are typically designer models and cost more than two-piece toilets. They’re also easier to clean as they don’t have as many creases and crevices as two-piece toilets.
  • Wall-mounted toilets, once found only in public restrooms, are becoming more popular for their minimalist looks. Unlike the models found at local fast food restaurant restrooms, they feature designer aesthetics. They consist of a seat attached to the wall with no visible toilet tank. Keep in mind these toilets require custom plumbing.
  • Bidet-toilet combos offer the flushing power of a toilet with the spray-cleaning function of a bidet. The tank includes a spray jet that emits a gentle stream of water.
  • Smart toilets automatically flush and can sense how much water is needed to perform an effective flush. This feature cuts water usage to as little as 0.6 gallons per flush (compared to the standard 1.6 gallons of a conventional toilet), which can save on utility costs. Smart toilets will also shut off when they sense a potential overflow or alert users via a smart device if it detects a leak. Some will even clean and deodorize themselves.
  • Composting toilets compost human waste using no water for flushing. An organic additive such as peat moss or sawdust is used to promote decomposition in a composting toilet, eventually creating matter that can fertilize soil.
  • Portable toilets are good options for camping, boating, RVing, and other situations where plumbing may not be readily available. Higher-end toilet models include multiple tanks—one for water that is used to clean the bowl via a manual pump and a second lower tank that holds waste until it can be dumped later.

Size

Although toilets range in size, most fit standard dimensions between 27 inches and 32 inches high, about 20 inches wide, and between 28 and 30 inches deep. Keep in mind that toilet height options are important to consider for those who are very tall or have mobility issues.

“Your standard height is going to be with the seat around 15 to 16 inches,” Cameron says. “Your comfort height is 18 inches, so it gives you a little height that makes it easier to sit down and get back up.”

All keep the rough-in distance mind, which is the measurement from the back wall to the center of the toilet drain pipe. Standard rough-in distance for most toilets sold at big box stores is 12 inches. While you can find toilets with smaller 10-inch rough-ins, Cameron says you’ll likely need to special order one.

Bowl and Seat Shape

While toilet bowls come in a wide variety of dimensions, there are three main shapes to consider: elongated, compact elongated, and round front. While all three options function the same, Cameron says it’s important to consider the available space in the bathroom when choosing one. “If I chose an elongated toilet in my bathroom, I’d probably have to step over it to get into my shower,” he says.

  • Elongated toilet bowlshave an oval shape that makes the seat more spacious and comfortable. They also add about 2 inches to the bowl’s length for an average overall length of about 18 inches from the seat hinges to the front of the bowl.
  • A compact elongated bowl shape offers a happy medium with a more oval shape that is about the same overall length as a round toilet, thanks to a narrower tank.
  • Round bowls don’t offer the comfort of an elongated toilet bowl. They are shorter at about 16 inches long, making them good options for smaller bathrooms in which space is at a premium.

If buying a toilet that does not come with a seat, it’s critical to purchase one that matches the toilet’s shape. Toilet seats come in various materials, including plastic, polypropylene, cushioned vinyl, composite wood, and real wood.

Efficiency and Flapper Size

When shopping for a toilet, consider how much water it uses with each flush. Toilets made prior to 1993 used between 3.5 and 7 gallons per flush depending on when they were made. While the current federal standard for flush rates is just 1.6 gallons per flush, you can find high-efficiency toilets that use just 1.28 gallons per flush, offering even more savings on your water bill.

Even though Cameron says these high-efficiency 1.28-gallons-per-flush toilets generally perform well, he suggests purchasing one with a larger 3-inch flapper over a model with a 2-inch flapper to avoid clogs.

Flushing Technology

Most toilets use the time-honored gravity flush to clear their contents. A gravity-flush system creates flushing pressure by releasing the tank water into the bowl, forcing all of the contents through the trapway leading to the drain and ultimately the sewer or septic system. Since these toilets use the natural power of water pressure, there are few mechanical parts to worry about, keeping maintenance relatively low.

Pressure-assisted toilets use the flushing power of siphoned air to create a much stronger flush than a gravity-flushing toilet. In addition to rarely requiring a second flush, they can also be quite loud. Pressure-assisted toilets, commonly found in public bathrooms, have been making their way into homes with the development of quiet-flush technology.

Dual-flush toilets are among the hottest flush technologies on the market. They feature two buttons: a little flush for “number one” and a more powerful flush for “number two.” These dual-flush toilets save water by using 0.8- to 1.1-gallon flushes for liquid waste and 1.28-gallon full flushes for solid waste and toilet paper. While dual-flush toilets offer savings, Cameron says it’s important to be realistic about how much water they’ll really save. “If you’re flushing anything solid, including any toilet paper, you’re going to have to use the 1.28,” he says.

Cutting-edge double-cyclone toilets use nozzles instead of tiny holes in the toilet rim and an innovative system that increases the pressure of each flush, allowing users to get the power of a full 1.6-gallon flush with just 1.28 gallons of water.

Style

Toilets offer a variety of looks, ranging from sleek and curvy modern single-piece toilets to vintage-style two-piece toilets with beveled edges and chrome handles. While white is still the predominant color for most toilets, some designer models feature other colors, such as black.

Though not as common, the minimalist design of wall-mounted toilets is also increasing in popularity. “The main thing here is you want to make sure it matches the other fixtures in your bathroom,” Cameron says.

Additional Features

There are many options to consider when shopping for a toilet. Here are a few of the special additions and considerations that some toilet brands feature:

  • Water usage: The standard modern toilet uses 1.6 gallons of water per flush, a far cry from toilets built in the 1960s and 1970s that used a staggering 5 to 7 gallons of water per flush. While the EPA considers 1.6 gallons to be low flow, some models go even lower, using as little as 1 gallon per flush to limit water usage.
  • Noise level: While pressurized toilets in public restrooms can hit an ear-popping 60 decibels or louder, most home toilets are around the 40-decibel mark. Still, quiet toilets might be around 30 decibels. Quiet toilets are good options for powder rooms adjacent to main living areas and guest rooms.
  • Slow-close options prevent the seat or seat cover from slamming. This is particularly useful in homes with small children.
  • Heated toilet seats eliminate the shock of sitting on a cold seat during chilly months while creating a more pleasant experience overall.
  • Deodorizers help to reduce smells continually. However, some are known to contain harsh chemicals.
  • LED lighting helps those who take late-night trips to the bathroom by providing more visibility.

FAQs 

If you’re wondering how to measure for a new commode or how to complete some basic toilet repairs, read on for answers to some popular toilet questions.

Q. How do you measure a toilet?

The best way to measure for a new toilet is to use its rough-in measurement. Measure from the wall to the center of the toilet’s drain hole. Make sure this matches the toilet rough-in measurement to ensure a proper fit.

You may also want to measure the toilet’s length, which is taken from the back of the tank to the front lip of the bowl, to ensure it will not take up too much space in the bathroom.

Q. How do you unclog a toilet?

You can unclog a toilet using a chemical method or manual method. If you own a plunger, stick the plunger into the bowl so that it covers the drain hole, making as tight a seal as possible around the hole. Make sure there is enough water in the bowl to cover the head of the plunger so that it can create enough suction. Begin slowly plunging until the clog is released.

If you don’t own a plunger, combine 1 cup of baking soda and 1 cup of vinegar and pour it down the toilet drain. The mixture will bubble up, loosening any clog in the toilet.

Q. How do you drain a toilet?

Turn off the water supply valve to the toilet, located near the floor on the wall just below the tank. Flush the toilet multiple times until most of the water in the bowl and tank has drained away. Use a sponge or old towel to remove any remaining water.

Q. How do you remove hard-water stains from a toilet?

Begin by adding 1 cup of vinegar to the toilet bowl. Use a brush to mix it in with the water, then let it sit for a few minutes. Add 1 cup of baking soda and another 2 cups of vinegar, which will cause the water to bubble and fizz.

After 10 minutes, scrub the stains with a brush. Let the mixture sit for another 30 minutes, scrub again to remove the stains completely, and then flush. Some toilet bowl cleaners are also effective at removing water stains.

Q. Why is my toilet not shutting off?

If your toilet continues to run after it’s done filling the tank, you likely need to replace the flapper, which is the rubber piece that covers the drain at the bottom of the toilet tank. The flapper is supposed to create a watertight seal over the drain while the toilet sits idle. If the flapper is faulty, it will not make a good seal, causing water to leak into the bowl continuously.

Q. How do I fix my toilet pump?

If your toilet pump, better known as the fill valve, is making screeching noises or takes an excessive amount of time to fill the toilet, it likely means that the fill valve has become clogged with sediment, which is hindering its ability to refill the tank with fresh water after each flush. You’ll need to replace the fill valve with a new one.

Q. How do I fix a toilet that runs intermittently?

A toilet that runs intermittently suffers from a leaky flapper that is allowing water to continuously run into the bowl through the drain at the bottom of the tank.

The intermittent hissing is the sound of your fill valve trying to keep the tank full as the water leaks out of it and into the bowl. You’ll want to replace the flapper to fix this issue (and halt the flow of money going down the toilet in the form of wasted water!).
