'Big Brother' 2019 Houseguests to Relive Childhood With Summer Camp House Theme

While we imagine it's absolutely liberating for the 16 new houseguests to enter the Big Brother house for the first time — and of course live in it all season — it's equally as exciting for the slew of superfans around the country watching from their own homes.

That's because, with every season, the theme of the entire house changes, and it's something the Big Brother nation looks forward to each summer. That said, while the layout of the home generally remains the same, each room is newly decorated and cleaned up from the previous crew. And 2019 is no different! Scroll down for a look inside the Big Brother 2019 house for Season 21!

Luckily for fans, the show's longtime host, Julie Chen, gave viewers a sneak peek inside the Big Brother house ahead of the Season 21 premiere on Tuesday, June 25 — and even revealed this year's theme! 

"Summer Camp is in session! The #BB21 House is Here! Double Tap if you’re ready to go camping with us all summer long!" she recently wrote on Instagram.

During the inside look at the house, Julie walked fans around the brand-new abode, better known as "camp B.B." for this season. The kitchen is equipped with wood cupboards, a camouflage palette, and a fun HOH sign above the cabinets.

And just like every season, this year is starting off with a large dining room table to fit all 16 houseguests. But as Big Brother fans know, that table will get smaller and smaller in time.

But for the first time ever, this year's dining room table features a large campfire right in the center to make s'mores. How cool!

The living room features a round birchwood coffee table, three elf sculptures on the walls, and of course, the classic sectional sofa where the houseguests sit for all important game ceremonies and live eviction episodes.

The bedrooms are designed with fun camping colors like yellow, red, blue, and green, as well as a portable camp stove and a vintage camper right inside the room! And in Big Brother fashion, the camper isn't just for show. The door of it leads to another one of this season's bedrooms!

The largest bedroom in the house is a sports-themed room that features fun camp-themed photos and memorabilia on the wall, as well as three double beds.

The famous lounge room, where the houseguests go to whisper and talk smack on each other, is themed as "camp B.B. on a lake," so it includes a big boat to sit on. 

The bathroom is also set up like a lounge this year and it even has three sinks for the houseguests to share!

And in a season of firsts, there is now two ways for the houseguests to get upstairs to the lounge, which is now a treehouse, and of course the highly-popular HOH room. For the first time ever, there are two different staircases in the house!

To finish up the house tour, Julie ended in the HOH room, which is equipped with a full king size bed with a fun, colorful comforter, as well as a private bathroom, another place the houseguests like to go for private talks.

But with the 16 houseguests already in the house, don't expect it to stay in tip-top shape for too long! The Big Brother house — which is located on a parking lot in Los Angeles  —  is known to become a major pigsty just a few weeks into the season. These people are all sharing this house for three months, after all...

"I’d say by Week 2 the house starts becoming very ‘lived-in,'" executive producer Rich Meehan told NY post. "[The houseguests] get very comfortable very quickly and their clothes are piled on the floor, on their beds, on their dressers. There are times when we’ve walked into the house and quickly leave. It’s pretty dirty and doesn’t smell the best."

“It smells like feet,” executive producer Allison Grodner added. “We have a discussion ahead of time about 'production issues' or 'roommate issues' and cleanliness is definitely a roommate issue, like if someone decides to be a complete slob and pile things up in the sink. We’ve had plenty of stories from people watching the show online about contestants coming out of the toilet and not washing their hands." 

That said, the cast usually dictates the status of the house. “It’s up to the houseguests to do their own cleaning, and some casts are real slobs and some are really neat,” Allison noted. “Inevitably there’s a neatnik in the cast. You start to hear, ‘I’m the only one scrubbing and cleaning.’”

But regardless of how messy the house gets, it's always perfectly renovated and cleaned for the next season. “It’s a set, so it gets demolished then rebuilt,” Allison confessed. “Prior to the [new] houseguests entering, we go in with an industrial cleaning crew and make sure the filth from the past season is gone. It’s like a construction site — it has to be vacuumed out and hosed down.”

Welcome home, Season 21 houseguests! Please just keep these campgrounds neat...
