Key Aspects:
- A suspected broken line aboard Harmony of the Seas sent water pooling through a passenger corridor shortly before 7:00 a.m. on September 29.
- One passenger who filmed the incident believes only two staterooms were actually flooded and praised Royal Caribbean crew members for responding quickly.
- Less than two hours later, affected carpeting had been removed and drying equipment was already being used as cleanup continued.
On a cruise, many guests enjoy soaking their feet, but for guests aboard Royal Caribbean’s Harmony of the Seas, this activity happened not at the pool, but in the hallway. Following a suspected broken line, water began pooling through a carpeted hallway on the 226,963-gross-ton ship.
One guest shared a video of the incident on Facebook, saying the incident occurred shortly before 7:00 a.m. on September 29, 2026. The video shows water flowing like a river down a section of the carpeted hallway, past some staterooms, including hers.
“That’s a first for me in 92 cruises!” said the passenger. “There’s a busted line on Harmony of the Seas. This isn’t a common occurrence, and the crew is handling it really well.”
According to the guest, the water was hot enough to steam up her phone as she recorded the flooding. However, the passenger did not report any burns or injuries as a result.
The guest believes that only two staterooms were flooded during the incident. She further commended the ship’s crew for their quick handling of the situation.
In a follow-up, shared around two hours after the initial video, the guest posted an image of the now water-free hallway, looking into a stateroom, where a crew member can be seen at work. The carpet inside the stateroom had already been pulled up, while crew members had deployed drying fans.
“Less than two hours after the flooding on Harmony of the Seas, the carpet has already been pulled up in the affected room,” said the guest.
It is not yet clear what caused the line to fail or exactly what type of line was affected. Royal Caribbean has not publicly commented on the incident, and no alteration to the ship’s itinerary has been announced.
Incident Occurred Ahead of Cozumel Call
The incident occurred on the fourth day of a five-night Western Caribbean cruise. The 5,697-guest ship departed Port Canaveral on September 26, 2026, and called at the cruise line’s private island, Perfect Day CocoCay, on the 27th.
Based on the ship’s itinerary, the incident occurred shortly before the ship’s scheduled arrival in Cozumel, Mexico, for the final call of the cruise. Harmony of the Seas is scheduled to return to Port Canaveral on October 1, 2026.
Burst Pipes Are a Recurring Problem at Sea
In spite of the guest’s assertion that such incidents are uncommon, this is far from the first time a burst pipe has caused problems on Royal Caribbean sailings. In July 2026, Cruise Hive reported on another viral video showing a room flooded by an apparent burst pipe on another Oasis-class vessel, Allure of the Seas.
A month later, in August, video surfaced of yet another water leak situation that had developed aboard Quantum of the Seas. As a result of another suspected burst pipe, water flooded down a stairwell near the Royal Esplanade, creating an impromptu waterfall.
These issues are not exclusive to Royal Caribbean, however. Cruise Hive has also reported similar incidents on other cruise lines, including Princess Cruises, MSC Cruises, and P&O Cruises.
In May 2026, Princess Cruises’ Enchanted Princess got its own unexpected water feature on Decks 4 and 5, following a burst pipe. Additionally, MSC Cruises’ MSC Seaview experienced a burst pipe in January 2026, and guests on P&O Cruises’ Azura found their cabin flooded in January 2025.
