Trying to cut down your water bill without dealing with weak flushes or clogs? Dual flush toilets are a smart way to go. They give you two flushing options—one for liquids, one for solids—so you only use the water you need. Less waste, more savings.
But not all dual flush toilets are created equal. Some models look sleek but leave you flushing twice. Others balance style, efficiency, and real-world performance. We’ve rounded up the best dual flush toilets that actually work—without sounding like a jet engine or leaving you with surprises in the bowl.

How to Choose a Dual Flush Toilet
Here are a few tips to help you pick the right one for your bathroom:
- Measure your rough-in: Most are 12″, but some older homes may be 10″ or 14″
- Check seat height: Comfort height (17-19″) is easier for most adults, especially seniors
- One-piece vs. two-piece: One-piece toilets are sleeker and easier to clean; two-piece toilets are easier to install
- Flush button position: Top-mounted buttons are the standard, but some offer side levers or wall-remote options
- Water savings: Look for WaterSense certification for proven efficiency
