Two-piece toilets (separate tank and bowl) remain the standard choice for most bathrooms because they’re cheaper to make, easier to ship, and simpler to repair than one-piece units.

The picks, in detail
American Standard Champion 4 Two-Piece
American Standard’s flagship flush-power line, built around a design that clears waste in a single flush — a common recommendation for households wanting to avoid clogs.
- Elongated bowl, chair height
- Soft-close seat
- 1.6 GPF
- Excellent flush power for the price
- Widely available with frequent retailer sales
- Not water-efficient compared to newer dual-flush/1.28 GPF models
Kohler Cimarron Two-Piece (K-31648-0)
Bob Vila and other review outlets consistently rank the Cimarron as Kohler’s best overall two-piece toilet, balancing water efficiency and quiet performance.
- Elongated bowl
- 1.28 GPF Class Five flush technology
- Soft-close seat included
- Strong flush performance at a water-efficient 1.28 GPF
- Widely regarded as Kohler’s best all-around toilet
- Some rough-in/model variants (K-31620 in biscuit or different trim options) run considerably higher
Kohler Wellworth Two-Piece
Kohler’s budget-tier two-piece line, positioned by the brand itself as the affordable alternative to the Cimarron.
- Round-front or elongated bowl options
- Class Five flush technology
- Dual-flush variants available
- Kohler build quality at a lower price point than Cimarron
- Dual-flush trim variants push the price close to the Cimarron

- Tornado Flush siphon jet system
- Cefiontect glazed bowl (resists residue buildup)
- Universal (comfort) height
- Excellent flush performance
- Glaze coating reduces cleaning frequency
- Priced well above the Kohler and American Standard budget options

- Right Height / ADA-compliant seat height option
- FloWise water-efficient engineering
- Strong flush performance for commercial or heavy-use bathrooms

Gerber’s ErgoHeight two-piece line, offered in both standard and ADA-height configurations with a slow-close seat.

- Slow-close seat included
- Solid mid-premium build at a competitive price versus TOTO/American Standard
- Less brand recognition among US buyers than Kohler or TOTO
Swiss Madison Well Made Forever Two-Piece (SM-2T140)
A budget-modern two-piece design that undercuts the major-brand names while still offering a dual-flush, elongated bowl.
- Elongated bowl
- Dual-flush 1.1/1.6 GPF
- Modern styling
- Lower price than comparable Kohler/American Standard dual-flush models
- Newer, less-established brand than Kohler/TOTO/American Standard
Buying tips
- Check your rough-in measurement (distance from the wall to the center of the drain, usually 12″) before ordering — most of these come in 10″, 12″, and 14″ rough-in variants.
- 1.28 GPF (WaterSense-certified) models save water over the older 1.6 GPF standard without sacrificing flush power on any of the picks above.
- Comfort/chair height (about 16.5-17″ bowl height) is easier on the knees than standard height and is now the default on most of these models — check the listing if that matters to you.
