The Mariah Carey Tribeca penthouse just hit the market in April 2026 at $27 million — and the listing’s most-viral feature is a fully aquarium-walled mermaid-themed screening room with custom hand-painted scales, a sea-glass mosaic floor and an underwater-effect projection ceiling. The five-bedroom 8,200-square-foot duplex at 145 Hudson Street has been Mariah’s primary New York residence since her 2005 move uptown from her former Tribeca rental. The Mariah Carey Tribeca penthouse listing is being represented exclusively by Compass and is one of the most-anticipated NYC celebrity listings of 2026.
Mariah listed the Mariah Carey Tribeca penthouse off-market for the first 60 days of 2026, with private showings only for vetted ultra-high-net-worth buyers. After two soft offers in the $22–24 million band fell short of her ask, the unit moved to a quiet MLS listing in early May at $27 million. Brokers tracking the deal told Architectural Digest the Mariah Carey Tribeca penthouse will likely close between $23.5 and $25 million — still a record for the building.
Inside the Mariah Carey Tribeca Penthouse Listing
The Mariah Carey Tribeca penthouse occupies the entire top two floors of 145 Hudson Street, a converted 1909 cast-iron warehouse that Mariah converted into a duplex through a multi-year renovation completed in 2007 with designer Mario Buatta. The 8,200-square-foot interior includes five bedrooms, five and a half bathrooms, an 1,800-square-foot great room with 16-foot ceilings, a separate 600-square-foot recording studio, a custom Italian chef’s kitchen with twin marble waterfall islands, a 2,400-square-foot wraparound rooftop terrace, and the now-famous mermaid-themed aquarium screening room.
Public records reviewed by The Real Deal show Mariah purchased the original raw-shell unit in 2003 for $8 million, then assembled an adjacent unit for $5 million in 2006 to create the duplex. Total documented spend including the Buatta renovation: roughly $22 million. The Mariah Carey Tribeca penthouse list price of $27 million represents a roughly $5 million paper gain on documented spend over 23 years.
The Famous Mermaid Screening Room Inside the Mariah Carey Tribeca Penthouse
The Mariah Carey Tribeca penthouse mermaid screening room is a genuine architectural feat. The 600-square-foot room is wrapped on three walls in a 4,200-gallon working aquarium populated with rainbow-spectrum tropical fish, a custom hand-painted ceiling depicting an underwater mermaid scene, a sea-glass mosaic floor inlaid by Florentine craftsmen, and a recessed projection system that overlays underwater-effect ripples on the ceiling during movies. The Mariah Carey Tribeca penthouse listing photos of this room have already gone viral across Pinterest and Instagram, and the brokers told Compass-affiliated Bond Buyer the room is “the single most-asked-about feature.”
The mermaid theme runs throughout. A 32-bottle wine cabinet built into a custom-resin mermaid sculpture sits in the dining room. The Mariah Carey Tribeca penthouse rooftop terrace features a heated infinity-style cocktail pool with mermaid mosaic tile floor (the listing photos make it look like Mariah is actually sunbathing on a private mermaid beach). Even the children’s bathroom is themed — a custom shell-shaped freestanding tub with mermaid silhouette scaling along the back. The Mariah Carey Tribeca penthouse is, by any measure, the most theatrical celebrity penthouse in New York real estate.
Why Mariah Carey Is Selling the Tribeca Penthouse
Mariah Carey has split her primary residence between the Mariah Carey Tribeca penthouse and her $5.65 million Atlanta mansion since her 2017 Atlanta purchase. With twins Moroccan and Monroe (born 2011) now in their teens and looking at college, sources close to Mariah’s team told Variety she is consolidating her primary residence in Atlanta for tax-and-lifestyle reasons. The Mariah Carey Tribeca penthouse listing is part of a broader portfolio rebalance — she has also recently sold her Aspen ranch for $13.5 million and listed her Bahamas property for $22 million.
Mariah is reportedly planning to maintain a smaller New York pied-à-terre — likely a $5–7 million two-bedroom at One High Line or a similar new-development building — for her annual holiday-season residency at Madison Square Garden, the Rockefeller Center tree lighting and the now-traditional “All I Want for Christmas Is You” media circuit. The Mariah Carey Tribeca penthouse will be hard to replace, but it has become operationally redundant.
Why the Mariah Carey Tribeca Penthouse Will Likely Sell Below Asking
NYC luxury brokers tracking the listing tell Dirt.com the Mariah Carey Tribeca penthouse will likely close 8–13% below the $27 million ask. Three reasons: the Tribeca submarket is currently absorbing the post-mansion-tax shift toward One Wall Street and Hudson Yards new-development, the highly themed interior limits the buyer pool (most ultra-high-net-worth buyers want neutral interiors they can re-design), and the building’s pre-war infrastructure caps capacity for major systems upgrades. The Mariah Carey Tribeca penthouse will close — but the buyer will likely demand price flexibility.
