KOHLER Toilet Guide: Numi Intelligent, Wellworth, Cimarron & Santa Rosa
KOHLER has been manufacturing toilets since the 1880s, and today offers everything from the budget-friendly Wellworth to the Numi intelligent toilet — the most advanced toilet in the world. This guide covers KOHLER's most popular toilet lines and the technology behind them.
One-Piece vs Two-Piece
| Feature | One-Piece | Two-Piece |
|---|---|---|
| Construction | Tank and bowl are fused into one unit | Separate tank bolts onto bowl |
| Cleaning | Easier — no seam between tank and bowl | More crevices to clean |
| Installation | Heavier (60-80 lbs) but one unit to place | Lighter pieces, easier to carry individually |
| Price | Higher ($300-$600+) | Lower ($150-$400) |
| Look | Sleek, low-profile | Traditional, familiar |
Popular KOHLER Toilet Models
Numi — The Intelligent Toilet
KOHLER's flagship intelligent toilet combines Japanese-style bidet functionality with cutting-edge technology. The Numi 2.0 features a heated seat, personal cleansing, warm-air dryer, UV light self-cleaning, ambient lighting, and built-in Bluetooth speakers. It's controlled via touchscreen remote or the KOHLER Konnect app. This is the future of the bathroom.
- Personal bidet cleansing with adjustable temperature and pressure
- Heated seat with multiple temperature settings

- Automatic open/close lid with motion sensor
- Ambient colored lighting and Bluetooth audio

Cimarron — Best Value
The Cimarron is KOHLER's most popular toilet for good reason. Its AquaPiston flush technology delivers a powerful, clean flush using 1.28 GPF (WaterSense certified). Available in both one-piece and two-piece configurations, the Cimarron's comfort height (chair-height) seating and elongated bowl make it comfortable for all users.
Wellworth — Budget Champion
The Wellworth is KOHLER's value line — reliable performance without extras. Class Five flushing technology provides a strong flush at 1.28 GPF. Two-piece construction keeps the price accessible. Available in round and elongated bowl shapes.
Santa Rosa — Compact One-Piece
Santa Rosa packs KOHLER's AquaPiston flush into a compact, one-piece design. Its smaller footprint fits tight bathrooms, and the one-piece construction is easy to clean. Comfort height seating is standard.
KOHLER Flush Technologies
| Technology | How It Works | Found In |
|---|---|---|
| AquaPiston | 360-degree flush valve allows water to flow from all sides — 2x more power than conventional flapper | Cimarron, Santa Rosa, most premium models |
| Class Five | Bulk flushing for reliable performance, canister valve design | Wellworth, Highline |
| Revolution 360 | Jetted bowl design with 360-degree swirl cleans the entire surface | Select premium models |
| CleanCoat | Nano-level surface coating repels water and debris, keeping bowl cleaner | Select models (add-on technology) |
Key Features to Consider
- Bowl shape: Elongated (oval) is more comfortable; round saves space in small bathrooms
- Seat height: Standard (15") vs Comfort Height (17-19"). Comfort height is ADA-compliant and easier for adults
- GPF rating: 1.28 GPF is the WaterSense standard. Dual-flush models offer 1.1/1.6 GPF options
- Rough-in: Measure from wall to center of floor bolts. Standard is 12", but 10" and 14" exist in older homes
Our Recommendation
For most bathrooms, the Cimarron comfort height elongated is the sweet spot — powerful AquaPiston flush, comfortable height, available in one-piece or two-piece. For a luxury master bath, the Numi intelligent toilet transforms the daily routine. As a Kohler Signature Store, we can walk you through every option.
