I'm not clear if you've replaced the vanities, which do need replacing if you're going to the expense of new granite, sink, and faucet. I don't see why you'd want to make those permanent, expensive changes based around a design scheme of outdated peach wallpaper.

^^^ This. I saw many that were similar. You could add “flocked” to the search, too. I’m certain this particular picture is a computerized stock photo, advertising something in the room, and the wallpaper (fake) is just edited in. A digital image. I saw this same picture with a yellow wall instead of the wallpaper. Other digital images with various backgrounds:

“The post does have a website attached to it, but they do not reference anything about the wallpaper 😕; it’s just a picture they posted... I also emailed, but no response.” It sounds like you didn’t contact the designer (I couldn’t tell from what you’ve written whether it was “Design Chic” that you contacted). The designer they say is Jenkins Interiors. That pic is on the Jenkins Interiors website under their bathrooms pics. Here is another pic from their website using that wallpaper. You can contact the designer using their website’s Contact Us page—unless that is what you already did: https://jenkinsinteriors.com/contact

I haven’t seen it in wallpaper form, just fabric (discontinued): https://www.kovifabrics.com/search/product-detail/6485 This similar one came up in wallpaper, but it’s peel and stick: https://www.decoratorsbest.com/products/waverly-wailea-coast-peel-stick-black-green-wallpaper?gclid=Cj0KCQjwj_ajBhCqARIsAA37s0y51_xHQWdr6j4YlCLD9lDanJltEvl0MZ6pr132YF3Bx_81RZFZQQEaAu5YEALw_wcB I hope someone else can find the one you’re looking for, good luck!
