There are shower facilities in the Admirals Club lounge in the same terminal that you arrive. It's right before you exit the gate area on the left hand side. Look for the signs.

note that you must visit flight connections first, before going to the AC or any other lounge since BAA decrees that they are for departing passengers only, not arrivers...
since you have 11 hrs, you might well wish clear to landside and use the AA Arrivals Lounge and then pop into the city..
