Overview
A genuine Kohler replacement flapper with a built-in float, 2-inch size, made for 1.6 GPF two-piece toilets across a specific list of Kohler model numbers, plus Kallista toilets that share the same valve.
This is a model-specific OEM part rather than a universal flapper. Kohler lists it against a long run of two-piece toilet series, including Wellworth, Revival, Iron Works, Kathryn, Portrait, Epernay, Alouette, English Trellis, Devonshire, Memoirs, Crimson Topaz, Close Reach, Folio, Wellington, Loon Lite, Fleur and Confidante, each with its own model numbers.
- Genuine Kohler part with float
- 2-inch size
- Fits listed Kohler two-piece models
- Also used in Kallista toilets
Who it's for
Owners of one of the listed Kohler two-piece toilet models, or a matching Kallista toilet, who need a factory-spec flapper replacement. Not for other brands or Kohler models outside this list.
Pros and cons
- Genuine Kohler OEM part
- Float design matches original flush tuning
- Long list of compatible two-piece models
- Not universal, must match your exact model number
- No adjustable dial like aftermarket universal flappers
Performance notes
The built-in float is designed to hold buoyancy through the flush cycle so the flapper seats consistently, matching how Kohler tuned flush volume on these two-piece toilets at the factory rather than leaving it to a generic adjustable design.
