How We Rate Toilets

Environmental Impact

Our Environmental Impact Rating for Toilets is based on a product's Consumption Rating (see below), manufacturing location and manufacturer's commitment(s) to environmental stewardship.

The higher the Environmental Impact Rating, the lesser the environmental impact of the toilet relative to others within the category.

Consumption

Our Consumption Rating for Toilets is based on a product’s gallons per flush (GPF) rating relative to other products within the category. The lower the GPF rating, the more water-efficient the toilet.

The higher the Consumption Rating, the more water-efficient the toilet.

Lifecycle Cost

Our Lifecycle Cost Rating for Toilets is based on a product’s cost of ownership, including its purchase price and cost of operation (water costs), relative to others within the category. A product’s return on investment potential is revealed in its Lifecycle Cost Rating since this rating uses the product's lifetime water cost in relation to its purchase price. In many instances, products that have higher purchase prices but also have higher efficiency ratings bring a quick return on investment through reduced utility expenses.

The higher the Lifecycle Cost Rating, the more cost-effective the product.

Price

Our Price Rating for Toilets is based on a product’s purchase price relative to that of others within the category. The higher the Price Rating, the better (lower) the price of the product.
