Window casing and conversion from inch thick drywall to half inch

trimwindows

I'm renovating the bathroom. I used to have 1" thick drywall and I'm lowering it to 1/2" thick drywall (so the window sticks out of the wall 1" now).

What are my options for trimming the window? Inch thick trim seems really thick. Is that normal?

Here are pictures of my attempted explanation…

Your options are:

  1. Use a second layer of 1/2" drywall to bring the wall flush to the window;
  2. Trim the window casing down by 1/2"; or
  3. Use inch thick trim on the window casing.

Personally I recommend #2 and would use what's called a Japanese saw:

or a multi-tool with a wood blade

to trim the casing down to be flush with the wall.
