I knew what you meant, LOL. I actually tried to go to Lowe's just now, since I was heading down to the Peninsula anyway... but I couldn't find the darned store! I'll try again tomorrow, and go the one that's easier to locate. Thanks all!

P.S. I found some furniture movers (like coasters you slip under the furniture), and put those under the tub - raised it probably 1/8-1/4 of an inch.
