Spec-by-Spec Comparison
Detailed Comparison
Kohler Tresham ($440-510) and Devonshire ($420-490) are both AquaPiston-flush two-piece comfort-height Kohler toilets in the same price bracket. Both 1.28 GPF, both elongated, both 12" rough-in. The differences are in detailing style.
Detailing comparison
The Tresham has cleaner, flatter detailing — reads more transitional than purely traditional. Tank profile is simpler with restrained molding. Suits bathrooms that mix traditional and contemporary elements.
The Devonshire has more visible period detailing with raised molded tank features. More overtly traditional in styling. Suits bathrooms committed to traditional design language.
Functional identity
Same Kohler AquaPiston canister flush — 10+ year canister lifespan with no flapper. Same 1.28 GPF. Same elongated bowl. Same comfort-height seat (16.5 inches). Both ship White, Biscuit, Almond. MaP 1,000g on both. From a daily-use perspective they're indistinguishable.
Bathroom matching guidance
The Tresham works in: transitional bathrooms (Shaker-style cabinets with brushed-nickel fixtures, mid-century-modern bathrooms with traditional touches), contemporary bathrooms with hints of traditional warmth.
The Devonshire works in: purely traditional bathrooms (Victorian, Edwardian, Colonial), classical-design bathrooms with pedestal sinks and claw-foot tubs.
Pricing parity
Both are within $20-30 of each other at most retailers. Price is rarely the deciding factor between them.
Suite-matching
If your Kohler bathroom suite includes Tresham fixtures (sink, tub), match the Tresham toilet. If your Kohler suite is Devonshire, match the Devonshire. For non-suite bathrooms, pick by which detailing style fits the surrounding fixtures.
Final Verdict
We recommend the Kohler Tresham for transitional bathrooms blending traditional and modern elements. Choose the Devonshire for purely traditional design with classical references. Both are functionally identical — match by surrounding fixture aesthetic.
