I am sorry I do not have your answer. Indeed I have a similar question. I
want to match a Toto Sedona Beige toilet and there is a perfect size
sink at Signature that comes in Biscuit. Kohler Biscuit matches
Toto Sedona Beige but Signature could not tell me what color their
biscuit matches. In American Standard the match is called Linen. Anyone
had any luck matching Signature Biscuit with Toto, Kohler or America
Standard?
Thanks!

Cheepchinese products are not even guaranteed to match each other much less a third party quality manufacturer.

Toto wasn't cheap. I am starting to gather that if theres a nonwhite option, like biscuit, it tends to be closer to white just warmer, rather than tan or beige which are not so much in style. But I'm not a "Pro"!

Toto is not Chinese.

If Signature Hardware cannot
guarantee a color match, I'd stay away from it. We have had a lot of
trouble with Signature Hardware sinks, including sinks that do not drain
properly, and sinks that do not actually fit in the template cut out provided
with the sink

And, Sophie Wheeler is right
about color matching. It's not true of all Chinese sinks. Some are
very good. But we don't know where Signature Hardware buys any particular
sink -- and, they they won't tell you. We have often seen products from some
Chinese manufacturers made at different times that do not color match. It
takes great skill to get the color exactly the same time after time.

Are you sure Toto or Kohler
does not have a sink that will work?

thank you for your well written comment.I need a sink that is 19 inches long to fit between a built-in and a toilet.I just double checked and neither kohler or toto has one that size. I have been looking for awhile. The signature victorian mini is right size. But color as well as quality may be an issue as you have described. The current sink is not working right now so really need one!

No, Toto isn't chinese. Signature Hardware though, is nothing but. Really iffy quality, with unlevel rims on sinks with two different bowl colors and faucets that go kerblooey.

Thanks for info. Will be leary of Signature.
