I need help improving the sound qualities of my ba

I have aall ceramic floors. The room is l shaped, 12 ft by 30 ft and 12 ft by 14 ft. The walls are cedar half way up and stucco to the ceiling. The ceilings are 7 ft. high.
I would recommend lots of area rugs. Also, look into DIY room treatments (wall panels, bass traps). They are fairly inexpensive and easy to build.
