Choosing a Toilet
What Toilet Model is Best?
With all of the different makes and models out on the market, it can be hard to know which toilet to choose. We have made the following independent toilet evaluation studies available to help you make your decision.
Maximum Performance Testing of Popular Toilet Models

This report is an independent study of the performance levels of certain toilets at a particular time. The performance bench mark levels for acceptable solids flushing performance used for this study is 250 grams. The condensed version of the study contains toilets sorted by manufacturer. The data illustrates the maximum loading that each model was able to successfully clear in a single flush at least two of three attempts. Models displayed in blue fail to meet the minimum requirements of 250g per flush.
