The well-disguised hiding spot flies under the radar and is impossible to see from the outside.
The cat was let out of the bag by TikToker @illegallyblondez, who shared a video revealing the secret with her 21,000 followers.
The clip opened with a shot of a blue rug on a kitchen floor.
The video’s audio, a popular choice on the app, said: “Everyone has that one thing in their house that everybody thinks is so cool.
“It could be a hidden cabinet, a little movie room, a gadget, but ours is this.”
A hand pulled the rug aside, revealing ordinary-looking wooden floorboards.
Next, a woman removed one of the floorboards and then lifted up a hatch hidden seamlessly in the floor.
A ladder led down from the open hatch into a basement.
The video then showed the influencer clambering down the ladder, lifting aside a curtain, and entering a secret low-ceilinged den.
The basement floor was covered with a white rug and cushions and pillows lined the walls.
Curtains hung all around the space lent a cozy sense of privacy to the room.
The final shot of the video showed a large television in one corner of the room.
This secret basement movie room went viral on TikTok, receiving 1.7 million likes and almost 8,000 comments.
The reaction from viewers was positive, with many expressing disbelief and jealousy that the poster had such access to such an intriguing space.
One person said: “I definitely need a house with this, or I need to learn how to build my own.”
Another commenter wrote: “I know where I’m hiding during hide and seek.”
