Halle Berry's Malibu House Hunt -- $50k Gets You a Bidet

Halle Berry is gonna have to drop $50,000 PER MONTH if she wants to live at that kick ass Malibu beach pad she was scoping out the other day ... TMZ has learned.

It's 3,825 square feet of pure AWESOME -- with 3 bedrooms, 4 baths, hot tub, elevator, white marble floors and a frickin' bidet ... so she can experience a spritz of France before she moves there permanently.

We broke the story ... Halle is in the market for a short-term rental while she fixes up some problems on her mansion in the Hollywood Hills.
