Water Efficiency

New flushing technology across various toilets has enabled water conservation without sacrificing flush performance. Most provinces require a maximum single flush capacity of 6 litres. The Home Depot is proud to only offer toilets that meet this efficiency requirement. In addition to adding comfort and style, replacing old, inefficient toilets will save a significant amount of water over time.

Flush Performance

A vital indicator of a quality toilet is the overall flush performance. A toilet with a higher flush performance will ensure that all waste is cleared within one single flush and mitigate the chance of clogging. Maximum Performance (MaP) scores measure that the toilet will perform as expected, and remove the waste levels indicated. What you choose should suit your needs based on the grams of waste expelled by the typical user. From 350 to 1000 grams of waste per flush, the rating system will ensure the toilet you choose is right for you and your family.


The distance between the floor drain and the wall, called the rough-in, is one factor to consider when selecting your toilet. The standard distance is 12”, and 10” or 14” are occasionally found in older homes. You can determine the rough-in on an existing toilet by measuring from the wall behind the toilet to the middle of the bolts on the base.
