Sigma21A simple classic

Sigma21 flush plate in black black walnut with red gold color accent

Sigma21 flush plates are based on the look of our popular Sigma20 Series, with upgraded finishes and options.

Sigma21 is available in glass and faux-look finishes, plus a unique slate finish, the first of its kind anywhere. Whichever you choose, Sigma21 upgrades the look of any bathroom.
