This one piece toilet has the clean lines that will make it perfect for a modern bathroom makeover. The siphon flush means it can use minimal water while still maintaining high performance. And the ADA (American Disabilities Act) compliant height means that all members of your family will be able to comfortably use it. See below for more information about ADA compliance.

BEST VALUE: Swiss Madison SM-1T112

Swiss Madison SM-1T112
  • Dual Tornado flush with high-performance gravity 0.8 / 1.28 gallon per flush (gpf).
  • Fully skirted design for sleek look and easy cleaning
  • Environment Friendly WaterSense toilets, meet strict EPA flushing guidelines.
  • Elongated & Comfort height bowl offers added room and comfort.
  • Soft Seat to close slowly and quietly.

Things to Like:

  • Skirted design for easy cleaning
  • Dual flush with low flow water conservation
  • Tornado flush for high performance
  • Soft Close seat

This is one good looking, great performing toilet, at an amazing price!

Dual flush is such a great, environmental choice too; one button for low flow liquid waste flush, and another for still-compliant solid waste flush – but the tornado action flush ensures that whichever you choose you can be sure that it’s gone.

We love the soft close seat (no more slamming toilet seats!), and the skirted bottom for easy cleaning (no more worrying about nooks and crannies!). Seriously, whether you need to replace a toilet or are doing a renovation, this toilet is worth looking at.

RUNNER UP: American Standard Fairfield

American Standard Fairfield
  • Vitreous china
  • High Efficiency toilet (4.8 Lpf/1.28 gpf)
  • Meets EPA WaterSense criteria
  • Low-profile, one-piece toilet
  • Elongated siphon action bowl

Things to Like:

  • Included seat
  • Powerful, low flow flushing action
  • ADA compliant height
  • Flushes quietly and fills quickly

This low profile toilet is designed to fit where perhaps others will not – under existing countertops when renovation is not the plan. There is no reduction in either style or performance though; this American Standard model is a top performer.

One thing to note when comparing this toilet to others is that the seat is included. Remember to consider this especially when doing price comparisons.

ADA Compliant Toilet Height

The Americans With Disabilities Act came into effect in 1990. Summarily it “…prohibits discrimination and guarantees that people with disabilities have the same opportunities as everyone else to participate in the mainstream of American life..”- a notion that just makes sense. The Act has a number of rules, regulations, guidelines, and standards that must be followed in public spaces to ensure that those who need assistance are afforded the same opportunities and conveniences available to everyone.

While the ADA doesn’t apply to private homes and residences, it can be helpful to know of some of the guidelines if there is someone in your family who may need assistance, or may be less mobile due to age or injury.

One of the simplest ways to help those with limited mobility is to install an ADA compliant toilet (another is to upgrade the toilet seat to a bidet toilet seat). Often referred to as ‘comfort height’ or ‘tall toilets’, an ADA compliant toilet must be between 17″ and 19″ tall when measured from the floor to the top of the toilet seat. This is the typical dimension of a standard chair, meaning that a person doesn’t have to squat in order to sit on the toilet; making it that much easier to get up from also.

You’ll notice that many manufacturers note their ADA-compliance in the feature list of their toilets. Be sure to look for this when choosing a fixture for your bathroom to ensure that your family will be comfortable, and safe, while using the toilet. It really can make a difference.
