Ever Wondered About Deck 1? Here’s Why It’s Not What You Think
When checking out a cruise ship deck plan, you’ll probably notice that many start at Deck 2 or higher—so, where exactly is Deck 1?
It’s a bit of a mystery for most cruise-goers, especially when passengers are assigned cabins on Deck 1 but have no idea what to expect.
Let’s uncover the truth behind Deck 1 and why many cruise lines tend to keep it a bit out of sight.
The Location of Deck 1: A Hidden Gem or Operational Hub?

Deck 1 is typically the lowest deck on a cruise ship, but its location and function can vary depending on the ship.
On some vessels, Deck 1 is located below the waterline, housing crew accommodations and operational spaces like kitchens and laundry facilities.
This is why many cruise lines skip over Deck 1 in their public deck plans, starting their layout at Deck 2 or higher.
But just because Deck 1 is sometimes hidden doesn’t mean it’s completely off-limits. Some cruise lines, like Carnival and Cunard, offer Deck 1 as a cabin location for passengers, though its accessibility might be limited or vary from ship to ship.
For larger ships, Deck 1 is often used as a crew-only area, with rooms, storage, and essential machinery that passengers typically never see.
When Deck 1 is Below the Waterline
On certain cruise ships, Deck 1 can be positioned beneath the waterline. While this may sound a bit intimidating, it’s not necessarily a bad thing.
The decks below the waterline are often reserved for crew quarters, as well as vital facilities like engine rooms and water treatment systems. In these cases, Deck 1 may be just above the waterline but still lower than the decks where passengers typically stay.
When Deck 1 houses passenger cabins, they’re usually inside staterooms with no windows. This is due to the rough, murky underwater conditions, which make providing a scenic view from the cabin a little impractical and potentially unsafe.
These Inside cabins on Deck 1 are often the most affordable option, making them a good choice for budget-conscious cruisers.
What Lies Beneath Deck 1?
If you’re curious about the hidden areas below Deck 1, there’s a whole world of activity that keeps the ship running smoothly.
From crew accommodations to essential facilities like laundry rooms, kitchens, and even the ship’s engines, the area beneath Deck 1 is a busy operational hub. The laundry facilities work non-stop to keep linens fresh, while kitchens prepare thousands of meals each day for passengers.
Engines and machinery critical to the ship’s movement and functionality are also housed below Deck 1. These areas are carefully maintained by the engineering team, ensuring that everything runs seamlessly throughout your cruise.

The Upsides of Staying on Deck 1
While Deck 1 may seem like an afterthought for some, it does have some unexpected advantages. For one, cabins on Deck 1 are typically more affordable than those on higher decks, making them a solid choice for travelers on a budget.
The lower deck location also tends to be quieter, as fewer people are usually moving in and out, which could make it easier to catch a peaceful elevator ride.
Additionally, Deck 1 is closer to the waterline, so if you’re prone to seasickness, staying on this deck might help you feel less of the ship’s motion compared to higher decks. The location makes the deck a popular choice for those who want to minimize rocking sensations.
The Trade-Offs: Is Deck 1 Right for You?
While Deck 1 offers benefits like lower prices and a quieter atmosphere, there are some potential drawbacks to consider.
Because many cabins on Deck 1 are Inside staterooms with no windows, you’ll miss out on natural light and any ocean views. If your priority is a stunning view, you might want to explore options on higher decks.
Noise levels can also be an issue. Engine sounds and vibrations are more pronounced on lower decks, so those sensitive to noise might find it distracting. Crew activity, particularly early in the morning, can also contribute to a less-than-peaceful environment, especially in the corridors near crew-only areas.
Deck 1 and Access: Not Always Open to Passengers
Another factor to consider is that Deck 1 isn’t always accessible to passengers. Depending on the cruise line and ship, this deck might be reserved for crew use or contain operational spaces like storage and maintenance rooms.
For ships with large crews or extensive operational needs, Deck 1 may be off-limits to guests entirely.
Why Midship Decks Are the Sweet Spot
If you’re not sure whether Deck 1 is right for you, midship decks (usually between Decks 6 and 8) might offer a happy medium.
These decks are more centrally located, balancing convenience with peace and quiet. You’ll have easy access to pools, dining, and entertainment areas, without the noise and motion experienced on lower or upper decks.
Conclusion
Deck 1 may not always be the most glamorous location on a cruise ship, but it’s far from being the bottom of the barrel.
With a prime location for battling seasickness and budget-friendly pricing, it’s a solid option for many passengers.
While noise and the lack of natural light might be drawbacks, Deck 1 can be a great choice for those who value affordability and a quieter cruise experience.
The next time you board a cruise, don’t overlook Deck 1—it might just be the hidden gem you’ve been looking for.
