Today....that is not going to happen, except with some of the instututional brands like Chicago and T&S. The public's tastes, and the demands of the marketing departments, demand frequent new styles and finishes.
Kohler and AmStd may be the ones if any. Delta, and PP used to have some "old standby" models, but that is not really true anymore. And with all the brands, availability of finishes varies from year to year. White and PB used to be the "fashion" finishes. Good luck trying to find those today.
