Question

"a" L-shaped room or "an" L-shaped room
L has a vowel sound,so i think probably is "an"    which is correct

Answer

An L-shaped room is correct.

"L-shaped" sounds like "elle-shaped".

Answer

Yes, use "an".  The 'n' is added to make the transit between vowels smooth.  This reflects the spoken convention, not the written convention.
