Which hotel has an aquarium in Singapore?

The property most directly answering that question is Resorts World Sentosa – Equarius Ocean Suites, a two-storey townhouse-style accommodation on Sentosa Island. The lower level — essentially a bedroom suite — sits alongside a massive aquarium habitat, visible through a floor-to-ceiling glass panel that looks into the water. The tank holds more than 40,000 fish, according to promotional material cited by travel content creators (TikTok). Guests sleep within centimetres of the glass, facing a wall of open water.

Equarius Ocean Suites at Resorts World Sentosa

Each Ocean Suite is a standalone two-storey townhouse. The upper level contains the living area, bathroom and private terrace; the lower level is the bedroom where the aquarium window is located. The suite is part of the larger Resorts World Sentosa complex — a mega-resort that also houses the former S.E.A. Aquarium (now Singapore Oceanarium), Universal Studios Singapore and a casino. The design means guests don’t need to leave the property to reach the aquarium entrance; it is literally on the same campus, about a 5-minute walk (same source).

One TripAdvisor reviewer who paid roughly USD 1,800 per night described waking up to “stingrays, sharks and schools of fish swimming past the window” and called it a bucket-list experience. The same reviewer, however, criticised the included breakfast as closer to a 2-star quality than the 5-star standard expected at that price point (TripAdvisor, July 2021).

Other aquarium-view options on Sentosa

Several hotels on the Resorts World campus offer proximity without the underwater window. Equarius Hotel (the main building, distinct from the Ocean Suites) and Equarius Villas provide standard luxury rooms and villa units on the same grounds. On Agoda, Equarius Villas shows an average nightly price around USD 1,108 and an average rating of 8.6/10 (same source). For comparison, Village Hotel Sentosa, Oasia Resort Sentosa and The Outpost Hotel Sentosa are also walkable to the aquarium and sit in the roughly USD 150–300 per night range (KAYAK). The trade-off is that none of these offer the in-room aquarium view.

Is there an underwater hotel in Singapore?

Strictly speaking, no room in Singapore is submerged underwater. The Equarius Ocean Suites lower level sits at ground level alongside the aquarium, not below it. The effect, however, creates a comparable experience — guests see the same framed view of marine life that the open-water tank provides. Several travel content creators use the phrase “sleep with the fishes,” and promotional materials lean into that imagery (same TikTok source).

What makes Equarius Ocean Suites underwater?

The design mimics an underwater perspective. The glass panel on the lower level is installed at the same depth as the aquarium’s main viewing gallery. Fish, rays and sharks swim past at eye level from the bedroom. The upper level is a conventional townhouse space with no aquarium view. The overall suite functions as a hybrid — part luxury townhouse, part private aquarium gallery.

Differences between a true underwater hotel and a suite with aquarium view

Examples of true underwater hotels exist in other countries — the Muraka at Conrad Maldives Rangali Island, for instance, sits 5 metres below sea level in the ocean. Equarius Ocean Suites is not that. It is a land-based room with a window into a human-made tank. The advantage is reliable sightlines (the tank is maintained and lit), but the experience lacks the ambient pressure, sounds and freedom of an open-ocean location. The distinction matters: one reviewer on Reddit noted that while the service is “hands down best … in Singapore,” the price — SGD 1,000–2,000 per night — “puts it in special occasion territory” (r/askSingapore).

Why is the S.E.A Aquarium in Singapore closed?

The attraction that gave the Equarius Ocean Suites their context — the S.E.A. Aquarium — is no longer operating under that name. The facility underwent a major expansion and rebranding, reopening as the Singapore Oceanarium. The closure, which extended from past renovation work into the expansion period, was reported by local publication Mothership.SG and independent travel blogs.

Renovation timeline

The original S.E.A. Aquarium closed to the public before the expansion that tripled its size. According to a review published in September 2025, the new Singapore Oceanarium now features 22 multi-sensory zones and a footprint roughly three times larger than its predecessor (Traveler Tina blog). The previous closure period affected anyone booking an Equarius Ocean Suite expecting to visit the old aquarium — guests staying at the hotel during the closure could not simply walk to the main attraction. The Oceanarium is now open, with peak-day admission for a family of four (two adults, two children) priced at SGD 196 (same source).

Rebranding to Singapore Oceanarium

The name change from S.E.A. Aquarium to Singapore Oceanarium reflects the expanded scope. The new facility includes additional tanks, a dedicated dolphin habitat and paid interactive experiences, including a dolphin petting programme. One 2025 review criticises the dolphin enclosure as “a very small space” and questions the ethics of allowing paid petting (same source). This may matter to travellers deciding whether to book a hotel that is directly tied to the attraction.

“If I had to pick one reason to skip the Oceanarium, it would be this: they keep six dolphins in a very small space and — for a fee — allow visitors to pet them.”

— Traveler Tina, independent travel blogger, September 2025

Equarius Hotel underwater room price and booking tips

Prices for Equarius Ocean Suites fluctuate significantly by season, day of week and how far in advance you book. The following table summarises what verified sources report.

Where to book: official site vs OTAs

The official Resorts World Sentosa website often includes packages that bundle breakfast or aquarium tickets, which can offset the very high breakfast surcharge at Equarius properties: SGD 54 per adult and SGD 27 per child for full breakfast (Expedia). Booking aggregators like Booking.com, TripAdvisor and Agoda sometimes show lower rates but rarely include the same perks. For a stay where the aquarium view is the goal, booking directly and confirming the room assignment as an Ocean Suite (not a standard Equarius room) is critical — the naming overlap causes confusion, and a standard room in the main Equarius Hotel will not have the window.

Singapore sea aquarium hotel review: what guests say

Aggregated reviews give Equarius Ocean Suites a 4.5/5 rating on TripAdvisor, but the spread reveals nuance. Below we summarise patterns drawn from multiple reviews (N≥3 per point).

Positive highlights

• The view is the draw. Nearly every reviewer who chose the Ocean Suite mentions the in-room aquarium as the highlight. Multiple guests say they spent hours lying in bed watching the fish.
• Service quality is high. Reddit users call it “hands down best service and hotel in Singapore ever” (same Reddit source). Butler service and personalised check-in are frequently praised.
• Location convenience. Being within walking distance of Universal Studios and the Oceanarium saves time during a Sentosa visit (same Trip.com source).

Common criticisms

• Breakfast quality. Multiple TripAdvisor reviews describe the breakfast as underwhelming for the price point — some call it “2-star quality.” At SGD 54 per adult for the buffet, the gap between expectation and delivery is a recurring pain point.
• Price-value ratio. Reviewers who paid above SGD 1,500 per night for the Ocean Suite often caution that it is a “once-in-a-lifetime” splurge rather than repeatable value. The city’s top-tier properties — Ritz-Carlton Millenia, Capella Singapore — are frequently cited as better overall value for a luxury stay (r/askSingapore).
• Limited inventory. The Ocean Suites are few in number. Peak-season availability is tight, and cancellation policies can be strict.

“Hands down best service and hotel in Singapore ever. However, it is on the pricier side… can range between $1k–2k/night.”

Our pick for different travellers

After weighing the verified price data, guest satisfaction patterns and location trade-offs, we recommend the following approach depending on your trip profile.

How to get to Sentosa and the Equarius properties

Sentosa Island is accessible from mainland Singapore via road (Sentosa Express, taxi, private car) or cable car. The Equarius properties sit within the Resorts World Sentosa complex on the north-east side of the island.

• Sentosa Express monorail: Board at VivoCity (HarbourFront MRT Station, Circle Line / North-East Line). Alight at Resorts World Station. From there, it is a roughly 5-minute walk to the Equarius buildings (same Trip.com source).
• Taxi / ride-hail: From Changi Airport, approximately 25–35 minutes depending on traffic. From Marina Bay, 15–25 minutes. Drop-off point is the Resorts World Sentosa lobby.
• Cable car: The Mount Faber line connects mainland Singapore to Sentosa Station, about a 10-minute walk from Resorts World.
• Parking: Guests of Equarius can use the hotel’s valet service. Self-parking is available at the Resorts World basement carpark for a fee.

The implication: staying on Sentosa works best if your itinerary is built around the island’s attractions (Oceanarium, Universal Studios, beaches, casino). If you plan to spend most of your time in the city centre, a mainland hotel near an MRT station will save you 20–30 minutes of travel each way.
