Complete buying guide for Best Water Efficient Toilets

Understanding Gallons Per Flush (GPF)

The primary metric for water efficiency in toilets is Gallons Per Flush (GPF). Traditional toilets often used 3.5 to 5 gallons per flush, while modern high-efficiency toilets (HETs) typically use 1.28 GPF or less. Dual-flush models offer even more control, with a lower flush (e.g., 0.8 GPF or 1.1 GPF) for liquid waste and a higher flush (e.g., 1.28 GPF or 1.6 GPF) for solid waste, maximizing water savings. Look for WaterSense certification, which guarantees the toilet uses 1.28 GPF or less and meets strict performance criteria.

One-Piece vs. Two-Piece Design

Water-efficient toilets come in both one-piece and two-piece designs. One-piece toilets integrate the tank and bowl into a single, seamless unit, offering a sleek, modern aesthetic and easier cleaning due to fewer crevices where dirt can accumulate. Two-piece toilets, with separate tank and bowl components, are generally more affordable and easier to transport and install, as the parts are lighter. Your choice often comes down to budget, style preference, and ease of installation.

Flushing Technology and Performance

Beyond GPF, the flushing technology plays a crucial role. Siphon jet and gravity-fed systems are common. Tornado flushes, like those seen in some of our reviewed products, create a powerful swirling action for superior bowl cleaning. A high MaP (Maximum Performance) rating indicates a toilet’s ability to clear solid waste effectively. Aim for a MaP rating of 1000g for excellent performance. A fully-glazed trapway also contributes to efficient waste removal and helps prevent clogs.

Comfort and Accessibility Features

Consider factors like bowl shape (round vs. elongated) and seat height. Elongated bowls are generally considered more comfortable for adults, while round bowls are better for smaller bathrooms. “Comfort height” or “chair height” toilets (typically 17 inches or more from floor to seat) are ADA compliant and make sitting and standing easier, especially for the elderly or those with limited mobility. Features like soft-closing seats and quick-release hinges also add convenience and quietness.

Ease of Installation and Maintenance

Some toilets are designed with easier installation in mind, such as those with larger side openings for bolts or complete installation kits. Skirted designs not only look cleaner but also simplify external cleaning. Internally, features like fully-glazed trapways and anti-microbial surfaces can reduce the need for frequent scrubbing. Reviewing user feedback on installation difficulty can be particularly helpful.

Frequently Asked Questions

What makes a toilet “water efficient”?

A toilet is considered water-efficient if it uses 1.28 gallons per flush (GPF) or less. These models are often labeled as High-Efficiency Toilets (HETs) and many are WaterSense certified, meaning they meet EPA’s criteria for both efficiency and performance. Older toilets can use 3.5 GPF or more, so upgrading can lead to significant water savings.

What is the difference between a single flush and a dual flush toilet?

Single flush toilets use the same amount of water for every flush, typically 1.28 GPF for water-efficient models. Dual flush toilets offer two options: a lower volume flush (e.g., 0.8 or 1.1 GPF) for liquid waste and a full volume flush (e.g., 1.28 or 1.6 GPF) for solid waste. This allows for even greater water savings by tailoring water usage to the specific need.

Are water-efficient toilets less powerful?

Not at all! Modern water-efficient toilets use advanced flushing technologies, like pressure-assisted or gravity-fed systems with optimized bowl designs and larger trapways, to ensure powerful and effective waste removal with less water. Look for models with a high MaP (Maximum Performance) rating (e.g., 1000g) for assurance of strong flushing capabilities.

What is a “comfort height” toilet?

A comfort height (or “chair height”) toilet has a seat rim height of around 17 to 19 inches from the floor, compared to standard toilets which are typically 14 to 15 inches. This taller height is more comfortable for many adults, especially taller individuals, the elderly, or those with mobility issues, as it makes sitting down and standing up easier. They are often ADA compliant.

Can I install a water-efficient toilet myself?

While many manufacturers design their toilets for DIY installation, it depends on your comfort level with plumbing tasks. Most toilets come with detailed instructions, and some even provide installation videos. However, if you’re unsure or prefer not to tackle it, hiring a professional plumber ensures correct installation and avoids potential leaks or issues.

Conclusion

Choosing the best water-efficient toilet is a significant step towards creating a more sustainable home while enjoying reduced water bills. From sleek one-piece designs with powerful tornado flushes to ADA-compliant comfort height models, the market offers a wide array of options that combine efficiency with modern aesthetics and user comfort.
