Man caves -- the last bastion of peace for the modern man. A refuge from a domestic empire of throw pillows, stemware and floral arrangements. After a long, hard day’s work, there’s nothing better than crawling down into the cave to flip on the game and throw back a few cold ones.

Of course, man caves aren’t just for regular joes. Rich and famous men also love having a little grotto devoted to manly pursuits. Here are some of the man caves of the rich and famous, and some lessons you can learn to transform your own cave.

Snoop Dogg

Rapper, family man, and man cave lover, Snoop Dogg (who has, of course, just changed his name to the more manly, “Snoop Lion”) has one seriously pimped out room to call his own. Looking to escape the stress of modern celebrity, the Long Beach, Calif., native had the DIY Network build him a custom cave where he could play video games and watch sports in peace. For a comfortable place to kick back, there’s a sheared-off trunk of a vintage Cadillac, which has been repurposed as a couch, giving the room a bit of retro-cool flair.

Windowless and ringed with security cameras, Snoop’s man cave is built to keep celebrity seekers, and uninvited family members, from busting in on his off-time. The cave even has a direct line to Denny’s to satisfy any late night snack cravings without ever having to step outside.

Takeaway for your own man cave: For lovers of classic cars, a couch fashioned from the classic fins of a vintage Caddy is a nice touch. For your own man cave, try heading over to the local junk yard or scouring the Internet for some classic auto parts -- a grill, headlights, or bench seats -- to adorn your walls and furnish the place.

Adam Carolla

Sure you want to impress your friends, but mostly you want them to be comfortable when they come over to knock a few back.

— Adam Verwymeren

Funnyman Adam Carolla co-hosted “The Man Show” for six years, so you’d better believe that he knows a thing or two about man caves. While his epic mansion sports an eight car garage to house his collection of classic race cars, Carolla’s basement man cave is a much more subdued affair. With a bar, a jukebox, bench seating and a pool table, the room looks more like a quaint local pub than an over-the-top celebrity man cave. And, of course, that’s a big part of the appeal of the man cave. Sure you want to impress your friends, but mostly you want them to be comfortable when they come over to knock a few back.

Takeaway for your own man cave:  Playing cards and coasters adorn the ceiling of Carolla’s cave. If you’re looking for a nice, affordable way to decorate the space while declaring your allegiance to your favorite brews, all you need is a bit of glue and a stack of coasters from your local bar.

Jimmie Johnson

NASCAR driver and fantastic son, Jimmie Johnson built a man cave for his dad as a Father’s Day gift. Decked out in racing memorabilia, a custom pool table clad in stainless steel takes center stage in the room. And while it also features a granite-topped bar and 3D television, the cave maintains its credibility as a functioning garage. A hydraulic lift allows the elder Johnson, a motorcycle enthusiast, to tuck away his Victory bike when it’s not in use.

Takeaway for your own man cave: The pit stop inspired cabinets are just repurposed tool chests, the perfect way for race fans to keep things organized in their own man caves. And the cave’s black and white checkered floor recalls a racing flag, a nice way to make you feel like you’re at the track when you’re kicking back at home.
