Lookin' for a place to pee? Try Chris Paul's brand new Houston-area mansion ... 'cause the dude has enough bathrooms to handle a small army!!! TMZ Sports has learned the NBA superstar purchased an 18,717 square foot estate in Spring, Texas -- 30 miles from the Toyota Center where the Houston Rockets play. Paul had been eyeing the mega-mansion for a while but finally closed on the place in October. It was originally listed for $8 MILLION ... but we're told CP3 got a good deal on it.
