85% of the Equinox 1,426 staterooms have a balcony. Each stateroom is equipped with at least a 32 inch flat-screen TV (suites have 40 and 52 inch TVs) and an 'on demand' audio/visual system that includes a library of over 5,000 complimentary songs and movies. There is also ship-wide Wi-Fi, although online@Celebrity, the ships internet cafe, is on the Atrium on deck six (the Continental deck). The ship has 11 different suite and stateroom options available from the 1,291 ft² Penthouse Suite (389 ft² balcony) to the inside staterooms at 200 ft².

There are many options including family staterooms (575 ft², 105 ft² balcony) and the 130 Aqua Class staterooms (194 ft², 54 ft² balcony) that latter situated close to the Elemis Aqua Spa with special dining and access privileges. Aqua Class guests also enjoy unlimited, complimentary access to the exclusive, Mediterranean specialty restaurant, Blu (aft on deck five). Other Aqua Class privileges include unlimited access to the spa ‘Persian Garden’ aromatherapy steam room that has heated ceramic loungers, and a relaxation room with panoramic views from comfortable wicker-type lounge chairs. The staterooms were designed with consultation from a panel of five women who were all from different travel backgrounds. This means that there was a lot more storage space than would normally be expected and nice touches such as footrests in the showers for women to shave their legs.

There are ten restaurants on board the Equinox serving a variety of food for all tastes from Asian fusion to steaks and burgers. The main dining area for day use is the buffet style Ocean View Cafe on deck 13 (the Lido deck) where there are any number of food options on offer from stir fry to salads and beyond.
