Key Aspects:
- Crew members are performing important maintenance on Oasis of the Seas’ plumbing system.
- While the repairs are completed, the toilets onboard will be unusable.
- Work is being completed in two-hour increments, with the majority of the maintenance being finished while the ship is docked in Nassau.
If the up to 5,602 guests currently onboard Oasis of the Seas have to go to the bathroom, they better be prepared to hold it.
On Wednesday, July 29, 2026, crew members were forced to take the ship’s vacuum system offline to complete important plumbing repairs. The vacuum system is needed to flush waste, meaning that the toilets onboard are temporarily unusable.
“To ensure our plumbing system continues to operate at the highest standard, our team will be performing essential maintenance that requires temporarily shutting off the ship’s vacuum system,” Royal Caribbean wrote in a letter to passengers, which was shared on Facebook.
“This work is scheduled to take place on July 29, from 10:00 am to Noon and 1:00 pm to 3:00 pm. During this time, toilets will not be operational,” the cruise line continued.
The work is being completed in two hour increments, with an hour break in between to allow guests to relieve themselves. All toilets should be functional again by 3:00 p.m. assuming there are no delays or complications.
On the bright side, the Oasis-class flagship will remain docked in Nassau, Bahamas, while the majority of the work is completed and there are plenty of working bathrooms on shore. The ship will be in the capital of the Bahamas from 10:30 a.m. until 5:30 p.m. EDT.
The current sailing embarked in Cape Liberty, New Jersey, on July 26 and already visited Port Canaveral, Florida, on July 28. One more port call is scheduled in CocoCay on July 30 before the ship returns to New Jersey on August 2.
Are Plumbing Issues Common?
Plumbing issues are not necessarily a daily occurrence onboard Oasis of the Seas, but isolated malfunctions like slow drains and temporary vacuum clogs do happen occasionally.
Though this has not been specifically confirmed by the cruise line, one passenger said that the 226,838-gross ton ship experienced a similar plumbing issue last week.
This would have been during the previous sailing, which was a 7-night Eastern Caribbean voyage that embarked on July 19.
“Last week Oasis of the Seas experienced an emergency shut down of all water resulting in not just water but no operating toilets for several hours. Today they appear to still have issues with that same problem,” the cruiser wrote.
Another passenger also noticed issues onboard the 2009-launched ship during their sailing in November of 2025.
“Someone posted in here last week about the plumbing backups and shutoffs and got absolutely destroyed for daring to mention that the ship was having plumbing issues. They were right,” the guest shared on Facebook.
“Not sure what the issue is, but there’s been issues all week on some floors and in public bathrooms. The promenade smells like a port-o-potty at the moment. Won’t stop me from coming back on her but it’s clearly a problem,” they observed.
Royal Caribbean works hard to maintain its ships, but sometimes things inevitably go wrong with thousands of people onboard at all times.
In some situations, guests are actually responsible for causing plumbing issues by putting things down the toilets that don’t belong there.
For example, Cruise Hive reported that one guest’s mistake shut down the flushing system onboard MSC Cruises’ MSC Meraviglia in March.
Carnival has also had to remind guests on more than one occasion that only the toilet paper provided by the cruise line should be flushed. Even different brands of toilet paper or wet wipes could spell disaster.
