Reverberant vocal room....

I want to create a vocal booth with a nice reverberant sound, but I also want to keep the clarity. Is this possible? I was thinking of making it rather large, like the size of a bathroom. I was thinking of using tiles on the floor and some of the wall to make it reverberant. Then I was thinking maybe of adding some bass traps in the corner to control the low frequencies so voices will still have clarity. Is this a possibility or will the bass traps eat up all the reflections anyway if i'm gonna have any control over the low frequencies. Any ideas??

you should probably try askin this in the acoustic forum
