A swingin' bachelor pad's bathroom? The lavatory in a villain's hideout? Actually the ultracool restrooms at the museum of things made between 1885 and 1945 look more like the facilities in the Batcave, so don't be surprised if at any moment crime-fighting superheroes Batman and Robin roll up in the Batmobile for a pit stop. Gleaming black-glass walls, stainless-steel sinks and fixtures, tiny halogen pendant lights brightening the way to relief. As gleaming clean as Alfred would keep it. Holy modern conveniences, Batman, this is the perfect place to adjust your tights!
