Tower B of this hotel, which is the other guestroom tower farther away from the canal and facing the neighborhood of Business Bay, actually opened one year later than its twin Tower A due to some guestrooms not having been fitted out at the time of Tower A's opening; however, its elevators and infrastructure had been installed around the same time as Tower A. Tower B also followed a similar layout of having restaurants and function rooms on the first few floors, guest rooms on most of the floors above, and another set of food and beverage outlets towards the very top. Its ground floor was home to a café and patisserie named La Farine, and the first floor was an extension of Kitchen6, the hotel's all-day buffet. The second floor had an Italian restaurant named Positano, while the third floor housed a hair salon connected to the spa and wellness area within the podium. Floors 4 had a Thai restaurant called Tong Thai, while floor 5 featured a Japanese restaurant aptly named Izakaya, which shared an outdoor terrace with the Peruvian restaurant inside Tower A. Floor 6 had an events-only restaurant named Business Bay after the hotel's location; having an entire restaurant reserved strictly for banquets seemed to exemplify how the hotel was geared towards conventioneers. As was the case with Tower A, the mezzanine level above floor 6 (also called floor "S1"), as well as the floor immediately above that (called "TF") were dedicated mechanical floors, except the mezzanine-level hallways leading to the pool deck on the roof of the podium. Again, guestrooms were on floors 7-35, 37-67, and 69-70, with floors 69 and 70 only consisting of duplex penthouse suites, while 36 housed administration offices and a refuge area and floor 37 had a second executive lounge. As was the case with Tower A, there were two additional mechanical floors between floors 35 and 36, as well as one another between 70 and 71 and four above 72, which were under a separate numbering system as floors S2, S3, etc. Unlike Tower A, the top-of-house dining venues in this tower were all third-party (i.e., not overseen by the hotel's F&B team); floor 68 had an American-style gastropub called Weslodge Saloon, a brand originating from Toronto, while the duplex space on floors 71 and 72 housed a Latin American restaurant and bar named Hotel Cartagena (upon hearing the name one may be reminded of Hotel Beaux Arts Miami, a boutique hotel on the top few floors of another JW Marriott Marquis property in Miami, but this one is strictly a restaurant not a second hotel), apparently run by the same team behind the former.

With the core plans of Tower B being nearly a mirror image of Tower A, this tower also had 14 elevators, consisting of four low-rise cars, four high-rise cars, four service cars, one top of house passenger car, and one elevator serving the top of house kitchen. This video features the bank of four low-rise passenger elevators among them, consisting of three panoramic cars and one passenger car. The scenic cars ran along the tower's southern wall, giving a good view of the Dubai Water Canal as well as the motor bridge laid across it. In terms of fixtures, these were basically identical their counterparts within Tower A. Again, while their speed was not slow, they could have been made faster considering the hotel's massive size and room count.
