The Best Toilet for Your Home

Measure Your Space
Toilet rough-in is measured from drain to wall.

Before you shop for the best toilets for your family, determine how much space you have to install it. The most important of these measurements is the distance between the floor drain and the wall, called the rough-in. The standard distance is 12-inches but a distance of 10- or 14-inches is occasionally found in small bathrooms or older homes. 


Determine your bathroom's rough-in by measuring from the wall behind the toilet to the middle of the bolts on the base of the toilet.

Toilet Bowl Shape
A standard round toilet bowl and an elongated toilet bowl.

You can also measure from the rear wall to help determine the best toilet bowl shape for your space. Elongated toilet bowls measure up to 31 inches from the wall behind the toilet to the front of the bowl. Round toilet bowls extend up to 28 inches from the wall.



Toilet seats with features like soft-close are available for either toilet bowl shape.

Toilet Profile
Profiles of toilet bases show a visible trap, a concealed trap and a skirted toilet.

Toilets are part of a bathroom’s overall design, so consider its profile along with other features.


  • A visible trap is the most common style found in homes and shows the outline of the curving trapways on the toilet base.
  • Toilets with a concealed trap have a smooth surface at the base that provide a more modern look and can be easier to clean.
  • Skirted toilets give a contemporary profile with a sleek design that conceals trapways and also eliminates the rounded outline of the bowl.
Toilet Height
Toilet height is measured from the floor to the rim of the bowl.

Toilet height is measured from the floor to the top of the rim. Whether it's marketed as "chair height," "comfort height," or "tall height," the best toilets for you should have a rim height that makes it easy to sit down and stand up.


Standard-height rims are 14 to 15 inches from the floor and should work well for shorter people. If you’re taller, consider chair height toilets that have a toilet seat height of 17 inches or more. 


Tip: ADA compliant toilets meet the standards of the Americans with Disabilities Act and have a rim height of 15 to 17 inches.

Urinals

Urinals are commonplace in public men’s rooms. Residential urinals aren't seen frequently but can be a convenient feature in a man cave, garage workshop or wherever guys spend a lot of time.


Urinals are wall-mounted, so they don’t require much space and they typically use less than a gallon of water per flush. Ultra-low consumption – and even waterless – models are available.

Toilet Color

White is by far the most common color for toilets found in residential bathrooms but the best toilets for your home should match your personal style. Almond toilets can bring a subtle variation from the typical bright white porcelain. Black toilets have a dramatic and contemporary design to fit in chic decor.

Types of Flushing and Flush Ratings

The hallmark of quality toilets is having enough flushing power for waste and toilet paper. A flush performance rating system classifies toilets from low to high based on ability to remove solid waste and resist clogging. Look for these scores displayed on product packaging and on signs in your local store. Higher ratings mean better waste removal and clog resistance.


Here are some types of toilet flushing systems:


Single-Flush Toilets

  • Standard single-flush toilets use the force of gravity to create a strong siphon during flushing
  • Easy to repair
  • Most common model, often costs less


Dual-Flush Toilets 

  • Dual-flush toilets have separate flushes for solid and liquid waste
  • Uses a larger diameter trapway design to resist clogging
  • Needs less water to flush efficiently 
  • May require more frequent cleaning


Pressure-Assist Toilet 

  • Pressure-assisted toilets have a special flushing mechanism within the tank creates a siphon jet action 
  • Produces more forceful flushes than standard gravity toilets
  • Flushing action is boosted by air pressure and is less likely to clog
  • Good choice for families because it uses less water per flush


Power-Assist Toilets

  • Power-assisted toilets can also known as macerating toilets or upflush toilets
  • Ideal for installing in new bathrooms located in basements
  • Pump permits flushing from below the sewer line
  • Macerating pump liquifies waste during flush to reduce clogging and promote flow in lengthy waste lines
  • Some models designed for boats or RV use
Water-Saving Toilets

Toilets account for nearly 30 percent of an average home's indoor water use and an efficient toilet can reduce water bills.


The Home Depot has developed its own Eco Options program to encourage earth-friendly living and is a partner of the Environmental Protection Agency's WaterSense program. WaterSense toilets use up to 60% less water per flush than other toilets and can save you up to $100 per year on your water and sewage bill.


Use our Local Utility Rebate Finder to help you find out if your purchase of water saving eco-friendly toilets qualify for a rebate from your local water district.


Tip: New flushing technology enables water conservation without sacrificing flush power, so it is recommended that you replace any toilets installed before 1994.

Toilets with Technology

Advances in ceramic technology have allowed some manufacturers to use easier-to-clean surfaces like ultra-smooth antibacterial glazing in toilet bowls that is designed to repel soil and inhibit the growth of stain- and odor-causing bacteria.


Smart toilets can add luxurious features to those found in traditional bidets. Often contained to a toilet seat unit, these personal cleansing systems can provide multiple settings for hygenic cleaning with warm water, heated seats and air dryers, reducing the need for toilet paper.
