Thank you Mr. Allison, and sorry about the typo. All sizes given
should have been in INCHES and not feet.

The old medicine cabinet was about 14 inches tall. The new cabinet is
24 inches tall, so part of the wall stud must be removed or trimmed.

From what I understand, you are saying that I should be O.K.
notching-out part of the 2x6 wall stud and framing-in for the new
medicine cabinet with 2x4's... correct?

Thanks,
Dave
