After installing hundreds of toilets, I judge them on one thing above all: does it clear the bowl in a single flush? A weak flusher means double-flushing (which wastes the water you were trying to save) and more clogs. The good news is the best modern toilets are both powerful and WaterSense-efficient.
Here are three I’d put in any home, from the flush-performance champ to a great value. All are standard two-piece units that a handy homeowner can install in an afternoon.
Best Overall: TOTO Drake (Tornado/G-Max Flush)
The Drake is the toilet plumbers recommend most. TOTO’s G-Max/Tornado flush uses a powerful swirling action that clears the bowl in one flush and keeps it cleaner, and TOTO’s build quality and glazing are a step above. It is WaterSense-certified, so you get strong performance and efficiency. Hard to go wrong.
Best Flush Power: American Standard Champion 4
If you want maximum flushing muscle, the Champion 4 has the largest flush valve in its class and is famous for never clogging — it clears almost anything on the first try. The trade-off is it uses a bit more water than the most efficient models, but for a high-traffic or problem bathroom, the no-clog reliability is worth it.
Best Value: Kohler Cimarron (AquaPiston)
The Cimarron pairs Kohler’s AquaPiston canister flush (360-degree water flow for a strong, even rinse) with comfortable-height seating and clean styling, usually at a friendlier price than the TOTO. Widely available with easy-to-find parts. A great-looking, reliable toilet for most bathrooms.
How to Choose the Right Toilet
- Measure your rough-in (the distance from the wall to the center of the floor drain bolts) — almost always 12 inches, but check before buying.
- Decide on bowl height: standard or ‘comfort/chair height’ (taller, easier to sit/stand) — most adults prefer comfort height.
- Prioritize flush performance (MaP score) over fancy features — a strong single flush prevents clogs and double-flushing.
- Choose elongated bowl for comfort or round for tight spaces; confirm it is WaterSense-certified for efficiency.
- Budget for a new wax ring and supply line at install — never reuse the old wax ring.
FAQ
What is the best flushing toilet?
For raw flush power, the American Standard Champion 4 is famous for clearing the bowl every time and rarely clogging. For the best all-around combination of strong flush, efficiency, and build quality, the TOTO Drake is the plumber favorite. Both clear waste reliably in a single flush, which is what matters most.
What rough-in size toilet do I need?
Rough-in is the distance from the finished wall to the center of the closet bolts on the floor. The vast majority of homes use a 12-inch rough-in, but older homes sometimes have 10- or 14-inch. Measure before you buy — the wrong rough-in won’t fit.
Can I install a toilet myself?
Yes — it’s a very doable DIY job in an afternoon. Shut off and disconnect the supply, remove the old toilet, scrape off the old wax, set a new wax ring, lower the new toilet onto the bolts, tighten evenly (don’t overtighten or you’ll crack the base), reconnect the supply, and check for leaks. Always use a fresh wax ring.
Bottom Line
For most homes, the TOTO Drake is the toilet to buy — a powerful single flush, great build, and water-efficient. Want unbeatable flush power for a problem bathroom? The American Standard Champion 4. Looking for style and value? The Kohler Cimarron. Whatever you choose, check your rough-in and use a new wax ring at install.
