The Netflix series “How to Build a Sex Room” is more than just a fantasy. It’s not just a way to indulge fantasies. Mx. said that the best thing about growing older is not caring what other people think. Danger, 31, was strongly advised by his mother, a real-estate agent, to avoid such a specialized project. “You’re the ones who are living in it now.”Mx. Mx. They hosted a Thanksgiving party for 10 people there. The guests were impressed that they could eat dinner in a room decorated like naked women’s doors. Mx. Danger said.ImageMs. Rose with Mike Shayler, the general contractor who helps bring her sex-room visions to life on the show.Credit…NetflixThere was at least some curiosity. Ms. Belladonna is a hospitality worker and recalls guests “fondling the sexual toys on the wall.” “How to Build a Sex Room” follows twelve couples as they transform their bedrooms, basements, and spare rooms into places where they can indulge in sexual fantasies and rediscover intimacy. Melanie Rose, a British designer with white hair, entertains her clients with a handbag stuffed full of toys and floggers. She encourages them to imagine their own “Fifty Shades of Grey playroom.” Rose, who lives in Los Angeles has earned a reputation for being the Mary Poppins of sex room. Rose is a Netflix addition. With shows like “Get Organized With the Home Edit” (a show that focuses on personal problems and offers practical solutions), the streaming network is trying to capture the self-care segment of the home-improvement market. The next iteration of this concept is “How to Build A Sex Room.” Ms. Rose asks homeowners about their most intimate fantasies and encourages them to make design changes that will please everyone. Ms. Rose is challenged by guests and sets out to solve them. There are plenty of plumbing and Sheetrock problems, as well as sledgehammers. Vision boards are stuffed with graphics, renderings, and detailed descriptions of shower tiles and textured wallpaper. Mike, a plaid-clad contractor, is available to test the new leg restraints for a bed. It all ends with a big reveal and tears as the happy couple relish the transformation.”We’re going to make great use of this room,” said one guest, after she explored her new leather and neon retreat with a spanking bench and bondage cross, accessible by a ladder hidden beneath floorboards emblazoned with the warning, “Caution: adults at play.”At the center of the home renovation genre lies a mantra: Improvements should not just improve your life, but your property value. Kitchens and bathrooms should be designed with a future homeowner in mind, one who would be willing to pay a hefty sum for the Instagrammable space.ImageA basement sex room, hidden behind a moveable bookcase, designed by Ms. Rose.Credit…Netflix”How to Build a Sex Room” challenges the dogma. This is not about what happens behind closed doors. Instead of ending up in a farmhouse sink with Edison bulbs, you will find couples lounging on a tufted couch, their legs crossed over each other, and giggling about their new love life. There are rooms with mirrors that reach the ceilings and chains hanging from the ceilings. These rooms are not like the anonymous, interchangeable couples that you see on home-improvement shows. They have mirrors from floor to ceiling and chains hanging from the ceilings. Ms. Rose estimates that the cost of renovations for the show was between $30,000 and $70,000, though the homeowners didn’t pay the bill. The work was paid for by High Noon Entertainment, the production company. Ms. Rose has completed private renovations that cost upwards of $200,000. Rose said that the bedroom is a good place to start renovations. “Because it’s the area where we, as partners, sleep together, that is where we have sex. It’s also where we start our families. Why not make it more romantic? Matthew Carter and Shenika Carter saw their renovation project a way to save their marriage, which is a huge task for a home-improvement program. Ms. Carter, 41 years old, is the chief executive of Urban League of Metropolitan Denver. “We couldn’t figure out why there wasn’t intimacy.” The couple bought the five-bedroom home in 2019 and had made significant improvements to the basement, deck, and backyard. Ms. Carter stated that they were creating all the stuff for the children.

Their 5-year-old daughter slept in the bedroom, while Ms. Carter fell asleep in their living room. Rose took down the bedroom and the bathroom adjoining it, and changed the layout so that Mr. Carter, 38, who runs a truck-driving school with his wife, can now see her shower from the bed. They also added a stripper pole in the middle of the bedroom. Ms. Carter stated, “I’m originally from Atlanta, the home of the strip clubs.” She dances on the pole because she is from Atlanta. The family bed is gone. “That was a reckoning,” Ms. Carter said. Now, the bedroom is the couple’s favorite place. After family dinner, homework and bedtime routines, the couple retreats to their retreat each night, enjoying the improvements that they made to make sure they were satisfied with everyone else.
