A day at the spa starts with the room. Let’s Relax Spa Sukhumvit 39 (Phromphong) has been fully renovated after 12 years, with a Colonial-style look, pastel light, and a perforated design inspired by the era of Rama V and VI. I love that it feels designed for calm, not just functional massages.

Two big wins for me: the full-service spa menu (Thai Massage, Aromatherapy Oil Massage, Foot Massage, plus the signature Hot Stone Massage) and the added nail care section for manicure, pedicure, gel nails, and paraffin. The main consideration is practical: this is an e-voucher, so you must call the spa to lock in your appointment time.

Key Points to Know Before You Go

• Renovated after 12 years of serving customers, so the space is updated
• Colonial style + Rama V/VI-era perforated detailing creates a softer, warm ambiance
• Full-service massage options include Thai, aromatherapy oil, foot massage, and hot stone
• Nail care section added: manicure, pedicure, gel polish, and paraffin
• Close to BTS Phrom Phong, minutes away for easy scheduling around your day

Why Let’s Relax Spa Sukhumvit 39 Feels Like a Reset Button

If you’re in Bangkok with a few too many stops on your list, this kind of spa day can be the best “plan” you make. Let’s Relax Spa Sukhumvit 39 (Phromphong) is built as a one-stop place for relaxation and beauty, so you can go in for a massage and, if you want, add nail care too. The setup matters because you’re not spending your time hopping between locations.

What I like most is that the new look isn’t just cosmetic. The spa was fully renovated after 12 years, and the design blends Colonial-style elements with perforated detailing derived from the Rama V and VI era. That translates into a warm, day-spa vibe using light and pastel coloring. In plain terms: it’s the kind of environment that helps your shoulders drop without you having to work at it.

There’s also a clear menu path. The spa offers the kinds of services people actually come to Bangkok for—Thai Massage, aromatherapy oil massage, foot massage—and then adds a signature Hot Stone Massage. You get enough variety that you can choose based on what your body needs that day, not what you think you should try.

Sukhumvit 39 by BTS Phrom Phong: The Location Advantage

This is one of those practical Bangkok choices: it’s minutes from BTS Phrom Phong. That matters if you’re doing sightseeing most of the day and want a spa appointment that doesn’t turn into a transit headache.

Because this is a one-day experience, timing is everything. You’ll want to check availability to see starting times, then match it to your schedule. If you’re staying in Sukhumvit, being near the BTS typically makes it easier to arrive on time and avoid rushing.

Also, you won’t need a language hurdle from a guide perspective. The host or greeter is Thai, and the activity itself is a direct spa appointment process rather than a guided cultural tour. The focus stays where it should: getting you relaxed and cared for.

The Renovation: Colonial-Style Calm With Rama V and VI Details

The renovation after 12 years is a big part of why this spa feels current. Let’s Relax Spa Sukhumvit 39 was fully renovated and redesigned with a Colonial style approach. The spa also uses a perforated design detail derived from Rama V and VI’s era, plus light and pastel colors to create a warm ambiance.

Why should you care about any of this? Because the atmosphere affects how you feel during the session. A lot of Thai spas can be perfectly fine, but if the lighting and layout feel harsh or outdated, the “rest” part doesn’t fully land. Here, you’re walking into a space aimed at comfort, with design cues that feel distinctly Bangkok rather than generic.

If you’re picky about cleanliness and comfort, this renovation timing helps. It signals the facility has been updated, not just kept running. And since this is meant to be a day spa experience, the overall feel matters more than it would in a quick, no-frills stop.

Massage Choices That Actually Fit What Your Body Needs

This is a full-service menu, so you’re not locked into one option. You can choose among:

• Thai Massage
• Aromatherapy Oil Massage
• Foot Massage
• Hot Stone Massage, listed as the signature

The best value here is flexibility. If your legs are tired from walking, foot massage can be a smart, less time-committing choice (and easier to pair with other plans). If you want a full-body reset, Thai massage and aromatherapy oil massage are the usual go-tos. Hot stone is the standout if you like warmth and a slower, melting sort of relief.

One important note: what’s included depends on which option you select. That means your purchase needs to match your plan. If you’re buying an e-voucher expecting massage + nails and your option only covers one category, you’ll be disappointed. It’s worth taking a minute to confirm what your specific selection covers before you call to book.

Small practical tip

When you call the spa to book, be ready to describe what you want: massage type, and whether you also want nail care. Since nail services exist as an added section, asking up front helps you avoid time gaps.

Nail Care Added: Manicure, Pedicure, Gel, and Paraffin

One of the most praised highlights is that they added a nail care section. If you’re the type who likes to leave Bangkok with one or two “visible” upgrades, this matters. You can pair a massage day with nail care without taking extra transport time.

The nail menu includes:

• manicure
• pedicure
• Gel Nail Polish
• paraffin

Paraffin is often a comfort-focused add-on, usually chosen when you want extra softening for hands or feet. Gel polish is the practical choice if you want longer wear and a more polished look during travel.

The key detail for planning: your inclusion varies depending on the option you select. So, nail care may be included for some e-vouchers and optional for others. You’ll want to match your e-voucher to your expectations, then confirm the appointment details when you call.

This is also a good fit for couples or friends who want different services. One person can go for massage and another can prioritize nail work, as long as the spa can schedule the same general visit window. Just remember the appointment is something you secure directly with the spa.

What to Expect From Your Day Spa Appointment Flow

Since this is a spa e-voucher, your “itinerary” is mostly about selecting and scheduling the right services. Expect a one-day, appointment-based experience at the Sukhumvit 39 location.

Here’s the realistic flow that makes sense with the info you have:

1. Purchase and receive your e-voucher

If you select a future month, your e-voucher gets sent to your email at the start of the month you selected.

1. Call to book the appointment

You must call the spa to secure your appointment. The phone number is +66 02 662 6935.

1. Choose your service from the menu

You can pick Thai Massage, Aromatherapy Oil Massage, Foot Massage, Hot Stone Massage, and you can add nail care from the new section if your plan allows it.

1. Enjoy your session(s)

The visit stays focused on relaxation and beauty—no extra sightseeing stops, no travel between areas.

Because cancellation is non-refundable, you’ll want to only lock it in when your schedule is stable. And since the activity is valid for 1 day, check availability for starting times so you can pick the slot that works.

If you want the day to feel smooth, aim to book at a time when you’re not rushing right before dinner plans. A spa works best when you can let your body cool down afterward.

Price and Value at Around $22 Per Person

The advertised price is about $22 per person for a one-day spa experience. That’s relatively attractive in a city where spa pricing can swing a lot depending on the treatment and location.

The real value comes from what the e-voucher covers and how many categories you want in one stop. If your option includes massage and you use the new nail care section too, you’re getting more “day comfort” out of the visit. If your option only covers one service type, you may still pay extra for nail care later, depending on what you select.

So the best way to judge value is simple:

• If you want massage only, this is a cost-effective reset.
• If you want massage plus nails, make sure your specific e-voucher option matches that plan before you call.
• If you’re unsure, call the spa with your preferences first. Ask what your selection can include during your appointment window.

Booking Reality: The E-Voucher Isn’t the Appointment

This is the big operational piece, and it matters. This is a spa e-voucher, not a guaranteed reservation. You must contact the spa directly to book your appointment using +66 02 662 6935.

If you’re traveling with limited time, this is worth planning early. You don’t want to wait until the day before and discover the appointment times you want are already taken.

Also note:

• the host/greeter is Thai
• the language listed is Thai

That doesn’t mean you’ll be totally stuck, but it does mean you should be ready with the service names you want (Thai Massage, Aromatherapy Oil Massage, Foot Massage, Hot Stone Massage, plus manicure/pedicure/gel/paraffin) when you call. Keep it straightforward.

Who This Spa Day Suits Best

This experience fits you if you want:

• a single location for massage and optional beauty add-ons
• a renovated, comfortable day-spa setting with a distinctive Bangkok design vibe
• an easy commute, thanks to being near BTS Phrom Phong
• a menu with several common massage choices, including Hot Stone Massage

It might be less ideal if you hate phone-based booking. Since the appointment requires you to call the spa, you’ll need to handle that step yourself.

You’ll also appreciate this more if you want control. The menu lets you pick Thai, aromatherapy oil, foot massage, or hot stone—so you can tune your visit to how you feel that day.

Should You Book This Let’s Relax Spa Sukhumvit 39 E-Voucher?

Yes—if you’re ready to do one quick phone call and you like the idea of bundling relaxation with nail care. At around $22 per person, it’s strong value when the option you choose matches the services you actually want.

I’d book if:

• you’re close to BTS Phrom Phong and want minimal commute stress
• you want a renovated spa space with a Colonial-style, Rama V/VI-inspired design
• you’re interested in Hot Stone Massage and possibly the added nail services

I’d hesitate if:

• you need a fixed appointment time already locked in through the voucher alone (you’ll still need to call)
• your schedule is unpredictable, since cancellation is non-refundable
• you’re counting on nail care but your e-voucher option might not include it

If you do book, make your call with a clear list: which massage you want, whether you want manicure/pedicure, and whether you want gel polish or paraffin. That one step saves time and stops guesswork.
