Here are highly recommended luxury hotels in Singapore whose suites feature bathtubs and (or) offer champagne/butler arrival service — good options if you want an in-room bathtub plus champagne service on arrival or during your stay.

Top picks (what makes them good)

• Four Seasons Singapore — Presidential, Royal and one-bedroom suites have spa-style bathrooms (large bathtubs) and Executive/club benefits that include all-day champagne or evening cocktails and personalized arrival services. Good for refined service and club lounge perks. (fourseasons.com)

• Marina Bay Sands — Sands Premier and other suites have marble, spa-like bathrooms with two-person bathtubs; suites also include welcome amenities and bespoke minibar/cocktail service (ask concierge for champagne on arrival). Ideal for dramatic Marina Bay views and large-suite layouts. (marinabaysands.com)

• The St. Regis Singapore — St. Regis suites feature marble bathrooms with freestanding bathtubs and include St. Regis Butler Service (butlers provide beverage/arrival service and can arrange champagne on arrival or during turndown). Great if you want classic butler-led champagne service. (marriott.com)

• Raffles Hotel Singapore — Heritage suites with luxurious bathrooms and 24/7 dedicated butler service; butlers routinely arrange turn-down touches, bubble baths and welcome drinks — request champagne on arrival or as part of in-room amenities. Excellent for a historic, highly personalized experience. (news.com.au)

• Pan Pacific Singapore — Premier/Pan Pacific suites list deep Kaldewei bathtubs and Pacific Club privileges (champagne breakfast/afternoon tea/evening cocktails in the club lounge); arrival/limousine and welcome amenities available for suite bookings. Good balance of modern rooms and club service. (panpacific.com)

Other good options to consider

• The Fullerton Hotel — many suites have separate bathtub + shower and in-room dining/24-hour service; the Straits Club/club benefits include lounge offerings and can arrange champagne on request. (fullertonhotels.com)
• Capella Singapore and Four Seasons specialty suites — (if you prefer villas or ultra-lux suites) both brands typically provide large soaking tubs and can arrange in-room champagne or butler service — check the property pages or contact concierge for specifics. (See Four Seasons citations above; contact Capella for latest suite inclusions.)

Booking tips and how to guarantee champagne on arrival

• When booking, select a suite category (Presidential / Premier / One-Bedroom / Royal / Loft, etc.) — those listings usually show “bathtub” or “marble bathroom” in the amenities.
• Add a special request (or call the hotel concierge) to confirm “champagne on arrival” or “bottle of chilled champagne in-room on arrival” — many hotels will charge for the bottle or include it as a suite benefit if noted in the package.
• Ask about butler service (Raffles, St. Regis, Four Seasons) if you want the staff to present champagne personally and arrange turndown service/bath preparation.
• For guaranteed inclusions (complimentary champagne, limousine transfer, club access), check suite-specific pages or the hotel’s “suite exclusives” section and confirm by phone or email before arrival. (fourseasons.com)

Estimated price guidance

• Expect premium pricing for suites with these amenities — from high three-figures USD per night for some suites to well over USD 1,000+ per night for top specialty/presidential suites, depending on season and view. Exact rates change frequently; confirm availability and price on the hotel site or with a booking agent.

Would you like me to

• check specific dates and return exact availability/rates for any of these suites, or
• reserve a suite package that includes a champagne arrival (I can draft an email/script you can send to the hotel)?
