Buying Guide
Key purchase considerations
- Height and accessibility: Choose standard-height or ADA-height (around 17 inches) for easier seating and standing, especially for seniors or those with limited mobility.
- Flushing performance and water efficiency: Look for larger flush valves or dual-flush options to balance power and water usage (0.8–1.6 GPF ranges are common among standard-height models).
- Toilet type: One-piece toilets offer fewer crevices and easier cleaning; two-piece models can be more affordable and simpler to repair.
- Bowl shape and comfort: Elongated bowls provide more seating area; chair-height design adds comfort without increasing space needs significantly.
- Rough-in compatibility: Most toilets use a 12-inch rough-in, but check your bathroom’s plumbing before purchasing.
- Cleaning and maintenance: Skirted or smooth finishes reduce cleaning effort; consider models with glaze-coated trapways for smoother performance.
- Durability and warranty: Review warranty terms and the reputation of the brand for parts availability and service.
