Is there an underwater hotel in Singapore?
Yes — the Equarius Ocean Suites at Resorts World Sentosa on Sentosa Island is the property that answers that question. The operator describes it as a two-storey townhouse: an upper level with a living area, outdoor patio and private Jacuzzi, and a lower level that provides an underwater view of over 40,000 marine fish (Resorts World Sentosa). There are exactly 11 such suites, and they sit within the Equarius Hotel complex.
What exactly is an underwater hotel room in Singapore?
A better way to understand it: these are not submerged pods or glass domes. They are conventional hotel townhouses with a ground-floor living space that opens to an aquarium — the S.E.A. Aquarium — through a floor-to-ceiling window. The bedroom is on that lower level, meaning you wake up to the view of rays, sharks and hundreds of smaller fish swimming past. A guest review on Lemon8 described it as “the highlight of the room was definitely the huge glass panel with a full view of the SEA Aquarium.” The upper-level living area and second bedroom are above the water line.
“The lower level provides a window to a unique underwater view of over 40,000 marine fishes.”
— Resorts World Sentosa, official property description
The bottom line: Singapore does have an underwater hotel product, but it is an aquarium-facing suite rather than a fully submerged structure. The novelty is in the viewing glass, not in the room being below sea level.
What’s special about Equarius Ocean Suite?
The property’s main differentiator is the two-storey layout. Level 1 — the lower floor — is where the bedroom sits, with the aquarium-facing window. Level 2 has a separate living area, a second toilet, an outdoor patio and a private Jacuzzi (Resorts World Sentosa). The suite capacity is listed at 93 square metres, accommodating two adults and two children or three adults. A Lemon8 guest review confirms the layout with a king bed downstairs and a hidden Jacuzzi on the main floor.
Underwater views of 40,000 marine animals
The marine life visible from the suite includes species from the S.E.A. Aquarium, which holds over 100,000 individual animals. The suite’s glass panel gives a direct view into that environment. A KAYAK reviewer wrote: “The tub right in front of the aquarium was awesome.” The same set of guest reviews on TripAdvisor frequently uses the phrase “private underwater sanctuary.”
Private Jacuzzi and butler service in a two-storey layout
Round-the-clock butler service is standard. The operator lists buggy service on-call, private Jacuzzi access, daily minibar replenishment, and admission to Sentosa attractions as included benefits (Resorts World Sentosa). The suite also comes with a Nespresso coffee machine, Dyson hairdryer, and 50-inch plasma televisions.
What this means: The service model is more intensive than a typical city hotel — buggy and butler support are designed to compensate for the resort’s spread-out layout. A travel blog (Dania Experiences) notes that the property is on the edge of Sentosa away from main attractions, making the free shuttle service essential for dining and activities.
“Our stay at the Ocean Suite in Sentosa was truly unforgettable and felt like stepping into a private underwater sanctuary.”
— TripAdvisor reviewer
How much is the underwater hotel per night?
Published rates from the operator are not fixed in the supplied research, but third-party platforms and guest reviews consistently reference a price point around $1,500 USD per night. A TripAdvisor review describes it as “completely overpriced,” while other guests on Hotels.com call it “huge” and praise the view first.
Current price range for Equarius Ocean Suites
Because rates fluctuate by season and demand, the $1,500 figure should be treated as a common reference point rather than a fixed published rate. The suite sits in the upper bracket of Sentosa accommodation — standard rooms at the Equarius Hotel are typically below $500, making the Ocean Suites a significant jump. One reviewer on KAYAK contrasted it with the broader Beach Villas product, noting the Ocean Suites bring the private pool and aquarium access.
Is the price justified?
The trade-off is about exclusivity versus space. At 93 sqm with two levels, a butler, and direct aquarium access, the suite offers something no other Singapore hotel can. However, the same aquarium is accessible to day visitors for approximately $40 USD, and the hotel does not grant private after-hours access. The value case rests on whether the overnight experience — waking up to fish swimming — justifies the premium.
| Metric | Value |
|---|---|
| Suite size | 93 sqm (RWS) |
| Capacity | 2 adults + 2 children, or 3 adults (RWS) |
| Check-in / Check-out | 3:00 PM / 11:00 AM (RWS) |
| Marine life view | Over 40,000 fish (RWS) |
Why was Underwater World Singapore closed?
The predecessor attraction, Underwater World Singapore, closed on June 26, 2016, due to lease expiration. Resorts World Sentosa now operates the S.E.A. Aquarium on the same resort parcel, and the Equarius Ocean Suites sit adjacent to that aquarium. The closure of the older attraction created the space for the current hotel product — guests cannot swim with the fish, but they can watch them from bed.
Lease expiration and closure date
The closure was driven by a standard lease end, not by visitor numbers or financial distress. The property’s marine-life viewing experience is now provided by the S.E.A. Aquarium, which is open to day visitors and hotel guests alike.
What replaced Underwater World?
The current Equarius Hotel and its Ocean Suites occupy part of the same real estate. The original attraction site is now incorporated into the wider Resorts World network, which includes a casino, Universal Studios Singapore, and multiple hotels.
The catch: The closure of the dedicated oceanarium means that the current “underwater hotel” experience is a room with a window to an existing aquarium rather than a purpose-built underwater structure. That matters for travellers expecting a fully submerged stay.

Our recommendation
For travellers whose priority is the most direct fish-viewing access possible from a hotel room, the Equarius Ocean Suites is the only option in Singapore that delivers that. The price is high by local standards, and the experience is more akin to a luxury aquarium sleepover than a true submerged stay. However, for couples or marine enthusiasts who want a single night of exclusivity, the suite’s service package — butler, buggy, private Jacuzzi — adds enough to make it a reasonable splurge.
