Buying Guide

When choosing a high-efficiency toilet, there are a few key features to consider to ensure you get the best product for your needs. Here are some factors to keep in mind:

Water Efficiency

One of the main reasons to switch to a high-efficiency toilet is to save water. Look for products with a WaterSense label, which means they meet the Environmental Protection Agency’s criteria for water efficiency. These toilets use no more than 1.28 gallons per flush, compared to older models that can use up to 5 gallons per flush. This can save you up to 16,500 gallons of water per year.

Flushing Power

While water efficiency is important, you also want a toilet that can effectively remove waste with one flush. Look for products with a MaP score of at least 600, which means they can flush at least 600 grams of waste in one go. This ensures that you won’t have to flush multiple times, which can negate the water savings.

Comfort and Style

Don’t forget about comfort and style when choosing a high-efficiency toilet. Look for products with a comfortable seat height and shape, and consider the design and color options to ensure it fits in with your bathroom decor.

Installation

Finally, consider the installation process. Some high-efficiency toilets require a specific type of plumbing or installation method, so make sure you have the right setup before making a purchase. Additionally, some toilets may require professional installation, which can add to the overall cost.
