This 600W macerating toilet system is designed mainly for situations where traditional plumbing is difficult, such as basements or garages. It features an elongated, oval-shaped bowl with an ADA comfort height of about 18 inches, making it easier for most people to sit and stand. The toilet uses a rimless design and a single flush with 1.28 gallons per flush, which balances effective cleaning with water efficiency. Its standout feature is the macerator pump that can lift waste up to 30 feet vertically and 260 feet horizontally, ideal for remote plumbing.

The toilet includes three water inlets, allowing you to connect additional fixtures like sinks or showers, which is a plus for space-saving bathrooms. Installation is relatively straightforward without needing to break the floor, and extension pipes come with the package to help with different setups.
