What Are Macerating Toilets and Why Choose Them?

A macerating toilet is a self-contained unit that grinds waste and toilet paper into a fine slurry, then pumps it upward through a small-diameter discharge line. This technology revolutionizes basement bathroom installation by eliminating the need for below-floor plumbing or extensive excavation. Simple Project's macerating toilet systems combine durability with user-friendly design, making them ideal for basement spaces where traditional toilets aren't practical.

The advantages are significant: you can install a basement toilet virtually anywhere, even above the main sewer line. The system works quietly, requires minimal maintenance, and integrates seamlessly with your bathroom renovation plans. Simple Project offers models that range from basic units to smart toilets with advanced features, ensuring you find the perfect fixture for your needs and budget.

Step-by-Step Installation Guide for Macerating Toilets

Before you begin, gather your tools: a wrench set, adjustable wrench, screwdriver, measuring tape, and plumber's tape. First, identify your discharge location—the point where the pump line will connect to your main drain stack or existing plumbing. Most Simple Project macerating units can discharge vertically up to 20 feet or horizontally up to 100 feet, giving you exceptional flexibility in placement.

Start by positioning your macerating toilet in the desired location and securing it to the floor using the provided bolts. Next, connect the inlet to your drain line and attach the discharge hose to the pump outlet. Simple Project fixtures come with clear, color-coded connections to prevent mistakes. Secure all hose clamps firmly, then connect your electrical outlet—macerating toilets require standard 110V power. Finally, run a pressure test using water before putting your new basement toilet into regular use.

Choosing the Right Simple Project Fixture for Your Basement

Simple Project's bathroom fixture lineup includes traditional macerating toilets, one-piece smart toilets with integrated bidet functions, and upflush systems designed for complete basement bathrooms. Consider your space, budget, and desired features when selecting your unit. Their smart toilet options offer heated seats, automatic flushing, and water-saving technology—perfect for modern bathroom renovations.

Installation difficulty varies slightly between models, but Simple Project designs every fixture with the DIY homeowner in mind. Customer support is readily available if you encounter challenges, and their detailed manuals make troubleshooting straightforward. Investing in a quality Simple Project system ensures your basement toilet will perform reliably for years to come.
