For years, 2-piece toilets have often fallen short on water efficiency and performance, which is why I was eager to test the St. Tropez Two-Piece Elongated Toilet Vortex Dual-Flush. After hands-on experience, I can say it truly stands out with its dual vortex flush—creating a cyclonic rinse that cuts through waste efficiently using just 0.8 GPF for minimal water use, yet flushes strongly with a maximum of 1 GPF.
This toilet’s durable ceramic, scratch resistance, and comfortable elongated bowl make daily use smoother. Plus, the comfort height (17-19 inches) is great for taller users or ADA compliance. Compared to the Toto AQUIA IV, which offers exceptional quality but still uses a higher 1.28 GPF, the St. Tropez delivers better water savings without sacrificing flush power or comfort. Having tested both, I can confidently recommend the Swiss Madison St. Tropez for its smarter water use, comfort, and reliable performance that lasts.
Top Recommendation: **St. Tropez Two-Piece Elongated Toilet Vortex Dual-Flush**
Why We Recommend It: This model’s dual vortex flush creates a cyclonic rinsing action, drastically improving waste removal while using only 0.8 GPF—more efficient than the Toto AQUIA IV’s 1.28 GPF. It features a durable, scratch-resistant ceramic surface and a comfortable elongated bowl with a height of 17-19 inches, making it ADA-compliant and user-friendly.

What Is a 1.6 GPF 2PC Toilet and How Does It Function?
A 1.6 GPF 2PC toilet is defined as a two-piece toilet that uses 1.6 gallons of water per flush (GPF) to remove waste effectively. The two-piece design consists of a separate tank and bowl, which are joined during installation. This type of toilet is commonly used in residential and commercial settings due to its efficiency and performance in water conservation.
According to the U.S. Environmental Protection Agency (EPA), toilets account for nearly 30% of the water used in homes, making efficient models like the 1.6 GPF toilets essential for water conservation efforts. The EPA has also established a WaterSense program that identifies high-efficiency toilets, further emphasizing the importance of low-flow options such as the 1.6 GPF toilets in reducing water usage.
Key aspects of a 1.6 GPF 2PC toilet include its flushing mechanism, which often utilizes gravity or pressure-assisted technology to maximize water flow while minimizing the amount used. The two-piece configuration allows for easier transport and installation, making it an appealing choice for many homeowners. Additionally, these toilets are compatible with a variety of bathroom styles and designs, which adds to their versatility.
The impact of 1.6 GPF toilets is significant in terms of water conservation. By using less water per flush compared to older models that may use 3.5 gallons or more, households can reduce their water bills and contribute to sustainability efforts. For example, a household that replaces a 3.5 GPF toilet with a 1.6 GPF model could save an estimated 12,000 gallons of water per year, translating to substantial cost savings over time.
The benefits of using a 1.6 GPF 2PC toilet extend beyond water conservation; they also promote improved sanitation and hygiene. By flushing effectively with less water, these toilets can help reduce the chances of clogs and backups, leading to a more pleasant user experience. Additionally, many modern toilets come with features such as ergonomic designs, soft-close seats, and enhanced flush technologies, offering improved comfort and functionality.
Solutions and best practices for selecting the best 1.6 GPF 2PC toilet include researching models that have received high ratings from the EPA WaterSense program, as these toilets are tested for efficiency and performance. Homeowners should also consider the design and height of the toilet for comfort, as well as the ease of installation and maintenance. Reading customer reviews and consulting plumbing professionals can further aid in making an informed decision when selecting the ideal model for a bathroom renovation or new construction project.
