## Product: KOHLER Adair Toilet
**Brand:** Kohler

## Pros
- Uses a water-efficient flush system with Aqua Piston technology that aims to deliver strong flushing power.
- Generally more powerful flush compared to older lift-flap models from Kohler.
- Clean, attractive design that fits well in smaller bathrooms due to its compact comfort height.
- Installation is straightforward and can be completed successfully without much hassle.
- Slow-close seat cover helps reduce noise and prevents slamming.
- Reliable performance after the initial break-in period.

## Cons
- Flush performance is inconsistent; many users report needing two flushes to clear the bowl fully.
- Bowl shape is flatter than typical, causing waste and toilet paper to often sit rather than flush away cleanly.
- Considered weaker in flush strength compared to other Kohler models like the Cimarron.
- Some users encountered porcelain cracks on the initial unit, though replacements were handled promptly.
- Slow-close seat cover, while functional, feels somewhat cheap and less durable.

## Bottom Line

The KOHLER K-3946-0 Adair Comfort Height toilet offers a stylish, water-saving design with solid reliability and easy installation, making it a decent choice for smaller bathrooms. However, the compromise on flush power and bowl design means you might find yourself flushing twice more often than you'd like. If effective flushing is your top priority, you may want to consider alternative Kohler models like the Cimarron, which users praise for stronger flush performance and cleaner waste removal.
