Shaq Selling Massive 'Shaq- Apulco' Estate For $ 28million

Shaquille O 'Neal is ready to move out of his incredible 3- acre Orlando mega - mansion .. . and it could all be yours if you' ve got $28 MILLION floating around.

Shaq' s pad is famous and awesome ... 31 , 000 square feet with 12 bedrooms and a buttload of bathrooms.

Not to mention .. . a legendary " Shaq Center " athletic facility that is made up of a custom 6 , 000 square foot basketball court (with bleachers ) .. . where the NBA star once put Harvey Levin on his ass !!

The estate also boasts the " Shaq-apulco " outdoor area ... complete with a 95 -foot long swimming pool and a rock waterfall, according to The Wall Street Journal . Obviously, he' s got a hot tub , swim -up bar, walk-in humidor and wine cellar too .

Our sources say these days Shaq's spending most of his time in Atlanta and L . A . - - where he also has Shaq-sized mansions - - so it just didn' t make sense to keep the massive Orlando mansion. We 're told he plans to buy a smaller place in Tampa , where his mom lives, because that's become home base for the family .

The Orlando crib famously appeared on an episode of " Tanked" -- where Shaq got a custom Shaq Diesel fish tank installed in the home .

No word if that stays with buyer or not .
Shaq bought the property in 1993 for $ 3.95 mil -- but he' s done millions of dollars in custom upgrades and expansion .
