It will be nearly impossible to get the same exact tile. I have found that it is impossible to find tile from even 15 years ago.
Now, I am a plumber, not a tile contractor, but I see this issue all the time in bathroom renovations. I recommend you find a similar style or install a "fashion trim" between the two versions.
A good finish carpenter MAY be able to match that. It could get expensive if they have to custom build it. Most people in your situation just try to get something close or they remodel the entire bathroom.
Hey, is this your tile?
