Buying Guide
Flush Performance
Look for advanced flush technologies like Tornado Flush, pressure assist, or air pressure systems to ensure reliable bowl clearing with minimal clogs.
Water Efficiency
Choose models with lower GPF ratings or dual-flush options to reduce water use and save on utility bills.
Comfort Height & Seat Design
ADA or universal height toilets (17″–19″) improve accessibility and comfort, especially for seniors or those with mobility issues. Soft-close seats prevent slamming.
Bowl Shape & Rough-In Compatibility
Elongated bowls offer more seating space but require more floor room. Ensure the toilet’s rough-in dimension (10″, 12″, etc.) matches your plumbing setup.
Additional Features
Consider built-in bidet functions, auto flush, night lights, or easy-clean glazes like CEFIONTECT for enhanced hygiene and convenience.
Installation & Maintenance
One-piece toilets simplify cleaning but can be heavier to install. Two-piece models are easier to transport. Check if an installation kit or wax ring is included.
Frequently Asked Questions
What is the difference between one-piece and two-piece toilets?
One-piece toilets combine the tank and bowl into a single seamless unit, making them easier to clean and often more water-tight. Two-piece toilets separate the tank and bowl, which can simplify shipping and allow for replacement of individual parts.
How do I know which rough-in size to choose?
Measure the distance from the finished wall behind the toilet to the center of the drainpipe. Common rough-in sizes are 10″ and 12″. Choose a toilet that matches this measurement for proper installation.
Are low-flow toilets as effective as traditional models?
Modern low-flow toilets (1.28–1.6 GPF) with advanced flush mechanisms can perform as effectively as older 3.5 GPF models. Technologies like pressure assist and Tornado Flush ensure strong performance with less water.
