A firefighter spent $3,000 turning a broken swimming pool into a sunken man cave with a full-service bar. See inside.

• Ethan Richards turned his in-ground pool in North Carolina into a sunken man cave for just $3,000.
• The 18-by-20-foot structure includes a working television, a refrigerator, and a full-service bar. 
• Admirers flocked to open houses to get a peek at the man cave, Richards' listing agent said.

When Ethan Richards discovered his High Point, North Carolina swimming pool would need major repairs, he dove headfirst into a new idea.

Instead of filling his pool with water, he'd fill it with a man cave.
