The Best Toilet for Your Home

Measure Your Space

Before you shop for a new toilet, 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 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.

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

Round bowls require less room.

The Right Height for Your Toilet Seat

Toilet height is measured from the floor to the top of the rim. The best toilet for you should have a rim height that makes it easy for you to sit down and stand up. Standard-height rims are 14 to 15 inches from the floor and should work well if you’re 5'5" or shorter. If you’re taller, consider looking into chair height models that have a toilet seat height of 17 inches or more. 

Tip:  An ADA (American Disabilities Act) approved toilet will have a rim height of 15 - 19 inches.

Two-Piece Toilets

Two-piece toilets:

  • Have a separate tank and bowl

Wall-Hung Toilets

Wall-hung toilets:

  • Mount to the wall and eliminate the need for a toilet foot or base 
  • May cost more to purchase and install  
  • Are ideal for transfers from a wheelchair or walker  
  • Require a thicker, sturdy wall for mounting  
  • Require a wall drain rather than a floor drain

Types of Flushing Systems
Water Saving Toilets

The hallmark of a quality toilet is having enough flushing power for solid waste and toilet paper. You may want to base the type of flushing system you choose on how many people will be using your new toilet. Here are some popular types of toilet flushing systems:

Standard Gravity Toilet 

  • Uses the force of gravity to create a strong siphon during flushing
  • Easy to repair
  • Most common model, often costs less

Pressure-Assist Toilet 

  • A special mechanism within the tank creates a siphon-jet action 
  • Produces more forceful flushes than standard gravity toilets
  • Less likely to clog
  • Good choice for families

Dual-Flush Toilet 

  • Uses a larger diameter trapway that doesn't clog as often as others
  • Needs less water to flush efficiently 
  • May require more frequent cleaning 
Rating Flush Power

The Home Depot has a flush performance rating system. Each toilet is rated low to high based on its ability to remove waste and resist clogging. Look for these scores displayed on product packaging and signs in the toilet aisle of your local store.  

  • Higher ratings mean better waste removal and clog resistance.
Water-Saving Toilets
symbols to look for when shopping for water-saving or eco-friendly toilets

Toilets account for nearly 30 percent of an average home's indoor water use.  The Home Depot has developed its own Eco Options program to encourage earth-friendly living and is a proud partner of the Environmental Protection Agency's WaterSense® program. A WaterSense® toilet uses up to 60% less water than other toilets and can save you up to $90 per year on your water and sewage bill. 

Use our Local Utility Rebate Finder to help you find out if your toilet purchase qualifies 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.

Easier-to-Clean Toilets

Several toilet brands now make it simpler to keep your toilet clean and sanitary by offering everything from built-in automatic cleansing systems to easier-to-clean surfaces. For example, American Standard offers a wide range of toilets with its EverClean® surface. This ultra-smooth glaze repels soil and inhibits the growth of stain and odor-causing bacteria. 

Smart Toilets

Smart technology makes living easier throughout the home, including the bathroom. Features like automatic flushes, built-in sensors that signal leaks, overflow protection and more make smart toilets worth a look. While they are relatively more expensive initially, smart toilets can save money over the long run by sensing how much water is needed and flushing only as much as necessary. 

Toilet Installation

The Home Depot offers full-service professional toilet installation and sells complete toilet kits if you choose to self-install.   

Toilet installation kits include everything you need in one box – tank, bowl, toilet seat and wax ring. (Supply lines are sold separately.) These "all-in-one" kits ensure that you have the correct toilet parts the first time, saving you from return visits to the store to buy or exchange parts.
