Our Best Flushing Toilets Picks Reviewed
Good flushing depends on design, not on extra water. Modern flushing toilets use 1.6 gallons per flush or less, yet the best models outperform older toilets that used much more water. A wide flush valve, a fully glazed trapway, and an efficient rim or jet design all help waste leave the bowl quickly.
Types of Flushing Systems
- Gravity-fed: the most common type. Water drops from the tank into the bowl. Modern gravity toilets, such as the Gerber Maxwell Crest and TOTO Drake, flush strongly and quietly.
- Pressure-assisted: uses compressed air to push water into the bowl with extra force. These toilets resist clogs well, but they are louder.
- Air-assisted: some models, such as the Casta Diva 17.2-inch toilet, use air pressure to boost a standard flush.
- Dual-flush: offers two buttons, one for liquid waste and one for solids. The HOROW T0338W uses this system to save water.
How to Choose the Best Flushing Toilets
The right choice comes down to flushing performance, water efficiency, comfort height, and cleaning.
- Flush Performance: Look for a high MaP (Maximum Performance) score when it is available. A score of 800 grams or more is very good, and 1,000 grams is the top rating. Reviews of flushing toilets that mention few clogs are also a good sign.
- Water Efficiency: WaterSense-certified flushing toilets use 1.28 gallons per flush or less. The Gerber Maxwell Crest flushes at 1.28 GPF while still delivering strong performance.
- Comfort Height: ADA-compliant flushing toilets are about 17 to 19 inches tall. The HOROW T0338W and both Casta Diva models offer comfort height, which makes sitting and standing easier.
- Cleaning: The TOTO Drake uses CEFIONTECT glaze to prevent buildup, and one-piece designs like the HOROW have fewer seams. A soft-close seat, like the one on the Gerber Maxwell Crest, adds convenience.
- Installation: Tool-free installation saves time. The Gerber Maxwell Crest is designed for easy setup. Always confirm that the toilet matches your rough-in, which is usually 12 inches.
Tips for Better Flushing
- Flush only toilet paper and human waste, and avoid wipes.
- Adjust the tank’s water level to the fill line marked inside the tank.
- Replace a worn flapper, which can reduce flush power.
- Clean the rim holes to remove mineral buildup.

If you want a proven, low-maintenance model, the TOTO Drake uses a Tornado Flush and a stain-resistant glaze. If you want hands-free convenience, the Casta Diva 17.2-inch toilet offers foot-kick activation and an air-assisted flush.
Flushing Toilets FAQs
Common questions from buyers include “Which brand makes the best flushing toilets?”, “Are pressure-assisted toilets worth it?”, and “Why does my toilet flush weakly?”.
Which brand makes the best flushing toilets?
TOTO, Gerber, American Standard, and Kohler are known for strong flushing systems. Value brands such as HOROW and Casta Diva also perform well.
Are pressure-assisted toilets worth it?
They flush very hard and resist clogs, but they are louder and cost more. For most homes, a high-quality gravity toilet is enough.
Why does my toilet flush weakly?
Common causes are a low tank water level, a worn flapper, a partial clog, or blocked rim holes. Check these before you replace the toilet.
Do strong flushing toilets use more water?
No. Most modern flushing toilets use 1.28 to 1.6 gallons per flush. Their power comes from better engineering.
Is dual flush better?
Dual flush saves water by offering a smaller flush for liquids. It is a good choice if water efficiency is important to you.
