How To Buy a New Toilet

When finding a new toilet for your home, you should first consider the available size in your bathroom then determine your style preferences and budget. This guide will walk you through the different variety of options available so that you can easily find the best toilet for your home.


Before purchasing a new toilet, measure the amount of bathroom space you have available and consider your bowl shape preferences.

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 10 or 14 inches are occasionally found in older homes. Determine the rough-in in your bathroom by measuring from the wall behind the toilet to the middle of the bolts on the base, and compare to your desired toilet’s dimensions.

The Home Depot’s flush performance rating system assigns each toilet a numerical score based on the toilet’s ability to remove waste and resist clogging. You will see 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.
