- Flush performance and water conservation: Look for dual-flush options, usually 0.8 GPF for light use and 1.6 GPF for full flush, to balance waste removal with water savings.
- Access to plumbing: A removable flush plate or easy-access panel simplifies behind-wall maintenance and potential repairs without dismantling the fixture.
