Inside 'RHOC' Star Heather Dubrow's 20,000 Square Foot, 14-Bathroom Mansion

The house has a private movie theater and an infinity pool.

Those infamously wild Real Housewives cat fights will have a lot more room to play out.

ET's special correspondent, Antonio Sabato Jr., was given an exclusive tour inside The Real Housewives of Orange County star Heather Dubrow's massive residence, which is still under construction.

Kicking things off, the 46-year-old reality star revealed that the 20,000 square foot mansion has a whopping 14 bathrooms.

Why so many? According to Dubrow, "The key to a successful marriage is separate bathrooms."

Construction on the enormous mansion was supposed to be completed next month, but it looks like things might take a little longer -- which isn't surprising when you realize that the home also includes a private beauty salon, a vast underground garage, an infinity pool and an 18-seat movie theater.

The home is perfect for Dubrow and her husband of 16 years, plastic surgeon Terry Dubrow -- who stars on the E! medical docu-series Botched -- as well as their four children.

Dubrow is also gearing up to host a launch party for her upcoming book, which she co-wrote with her husband, and invited ET back to see her finished home in the spring.
