What brand? Whose the hinge manufacturer originally? Whose replacement hinges did you buy? Pictures?

Thanks for follow up.. The brand from 2006 was a Wave: Rhett Style Single Door 24x36-SRY2436. The original hinges were Grass Impresso. We dont have that hinge any longer to know model number. The hinges we tried to replace were Grass Impresso Soft Close 160 degree Hinge Straight Arm 701368.

Picture of other bathroom cabinet that has same model except it was 15 x 36 to show original type hinge on door. Another pic shows remaining original hardware in cabinet on the problem medicine cabinet. Unfortunately, the picture of our mirrored door shows modifications

The replacement hinges did not need screw holes because it was a different design hinge mounting. The

replacement hinge had a lever to make it expand inside the hole in the door. This required modifying the mounting hole in the door.
