Thanks Tim for your info.

In my case, this is to be the bathroom's 24 inch wide entry door. Next
time I am at HD, I will inquire about availability and sizes, etc.

I cannot go to the left due to existing electrical, and to the right,
means subdividing the master bedroom closet, which is small to begin
with. The depth of the closet is approximately 28 inches between
finished drywall walls.

I will Google for pocket door.
