Introduction

Updating your bathroom or replacing an old toilet? Modern toilets come equipped with advanced water-saving features, making them more efficient and eco-friendly. If your current toilet is a water hog, it’s time for an upgrade. Toilets manufactured before the Energy Policy Act of 1992 typically use 3.5 gallons per flush (GPF) or more, while newer models are capped at 1.6 GPF.

Water Efficiency Standards

Today’s toilets utilize cutting-edge flushing technology to operate at 1.28 GPF or even less, meeting EPA WaterSense criteria for performance and water efficiency. In many regions, replacing old toilets with water-saving models can qualify you for rebates from local utilities or municipalities.

Enhanced Features

Beyond water conservation, modern toilets offer a range of features for added comfort and convenience. From heated seats to night lights and more ergonomic designs, these toilets elevate the bathroom experience.
