How long have you had the white ones?

If they lasted a long time before showing wear, then I would probably replace them with new white ones.

If the white ones started chipping soon after you got them, then I would probably go with stainless this time around.

I have a polished nickel faucet and just chose stainless. It lasts and is easy to keep clean, plus it’s what came with my disposal.

Should I just go with stainless for the replacement drains?

Yes. Maybe a colored Blanco.

Your sink may be acrylic, but it's not Corian. There is no Corian logo and DuPont never made that style. Look underneath and I'm sure you'll find fiberglass reinforcement supporting the 1/8" thick acrylic. Not a bad sink, easily refinishable, but not Corian.

Thanks for the feedback. I think I’ll search for white replacement drains. They did last a reasonable amount of time. Is this a DIY job or worthy of a plumber to insure no leaks? My husband is quite handy but we don’t want to damage the sink in the process.

Easily DIY, particularly for the "quite handy".
