1. Flush Efficiency
Look for a toilet with WaterSense certification that uses 1.28 GPF or less. Dual flush systems give users flexibility for solid or liquid waste.

Elongated bowls offer more comfort, while round bowls are better for tight spaces.
3. Seat Height
ADA-compliant “comfort height” toilets make it easier for seniors or people with disabilities.
4. Build Material
Vitreous china or porcelain with a glazed finish resists stains and is easy to clean.
5. Design
Sleek, skirted, or concealed trapway designs enhance the look and make cleaning easier.
6. Installation
Ensure you know the rough-in measurement (typically 12 inches). Some models can be heavy and might need professional installation.

Frequently Asked Questions
1. What is the difference between one-piece and two-piece toilets?
One-piece toilets combine the tank and bowl into a single unit, making them easier to clean and typically more durable. Two-piece toilets have a separate tank and bowl, which can be easier to transport and often cost less.
2. Are one-piece toilets harder to install?
Yes, they can be. One-piece toilets are heavier and bulkier, often requiring two people for installation. Professional installation is recommended if you’re unsure.
3. Do one-piece toilets save space?
Absolutely. One-piece models tend to be more compact in both height and length, making them an excellent option for small or narrow bathrooms.
4. Is a dual flush toilet worth it?
Definitely. Dual flush toilets let you choose between a low-volume flush (often 0.8 GPF) for liquid waste and a higher-volume flush (1.28–1.6 GPF) for solid waste. This helps save water and reduce utility bills over time.
5. How long do one-piece toilets last?
A high-quality one-piece toilet can last anywhere from 20 to 30 years with proper maintenance and occasional replacement of internal components like the flapper or fill valve.
Final Verdict
Choosing the best one-piece toilet in 2025 depends on your bathroom size, budget, and comfort needs. From high-end models like the TOTO Ultramax II to space-saving budget choices like HOROW and DeerValley, there’s something for every homeowner.
If you’re redesigning your bathroom or replacing an old toilet, invest in a high-quality one-piece toilet for better hygiene, aesthetics, and long-term satisfaction.
Whether you prioritize water efficiency, sleek design, or affordability—this guide has helped you make an informed choice.
