Thermae Bath Spa Review: Is It Worth It?

I’ve been to Bath three times and I’ve now been to Thermae Bath Spa twice.

On my first trip to Bath, I knew I wanted to visit the Roman Baths. But after spending hours learning about people coming to Bath for centuries because of its natural thermal waters, there was something especially appealing about getting into those waters myself.

Not at the Roman Baths, obviously. (You definitely can’t swim there anymore.)

Instead, modern visitors can experience Bath’s naturally warm, mineral-rich water at Thermae Bath Spa, a contemporary spa complex right in the center of the city.

On both visits, I splurged on a spa package with treatments and cream tea—the first time because I deserved it after walking the Cotswold Way and the second time because I wanted it.

So is Thermae Bath Spa worth it?

For me, yes. I would absolutely go again.

But I’d go primarily for the thermal pools, rooftop views and Wellness Suite rather than the treatments. I enjoyed my treatments both times, but the thermal-water experience is what makes Thermae Bath Spa special.

And there are definitely a few things I wish I’d known before my first visit.

Here’s what it’s actually like.

[Ultimate Guide to Bath for Book & Movie Lovers] (COMING SOON!)

What Is Thermae Bath Spa?

Bath has been attracting people to its thermal waters for centuries.

The Romans built an enormous bathing and temple complex here. Later generations continued to believe in the healing qualities of Bath’s waters, and by the Georgian era, “taking the waters” had helped transform Bath into one of England’s most fashionable destinations.

Today, you can see that history at the Roman Baths. (Find out more: Visiting the Roman Baths: What to Know Before You Go)

But you can’t actually get into the water there (at least not anymore).

That’s what makes Thermae Bath Spa different.

This is a modern spa where you can bathe in Bath’s naturally warm, mineral-rich thermal water while looking out over the historic city.

What Does a Regular Thermae Bath Spa Visit Include?

A standard Thermae Welcome spa session currently gives you two hours to use the main spa facilities.

Those include:

• the open-air Rooftop Pool
• the indoor Minerva Bath
• the multi-sensory Wellness Suite

A robe and towel are provided.

You need to bring your own swimsuit and footwear, such as flip-flops or sliders.

That last part is important. (Don’t be the person standing in a Bath hotel room realizing you packed for England but somehow forgot that your trip includes a swimming pool…that was me.)

The Rooftop Pool Is the Star

Let’s start with the reason you’ve probably seen Thermae Bath Spa on Instagram.

The rooftop pool…it’s pretty fantastic.

You’re floating in warm thermal water while looking across the rooftops of Bath, with the city’s honey-colored buildings and surrounding hills stretching around you.

And because the pool is outside, the experience changes with the weather and time of day.

I loved simply floating there and looking around.

Don’t Skip the Wellness Suite

The Wellness Suite was one of the areas I didn’t fully appreciate on my first visit.

There are several different “thermal and sensory spaces”, including Roman and Georgian steam rooms, an infrared room, an ice chamber, experience showers and the Celestial Relaxation Room.

On my second visit, I discovered the Celestial Relaxation Room. (How did I miss this the first time?)

The room has a space-inspired atmosphere that made it feel like you were relaxing beneath the stars, and I found it incredibly peaceful.

Admittedly, I am a sucker for anything involving stars and it ended up being one of my favorite spaces in the spa.

My only complaint about the Wellness Suite is that some of the rooms feel fairly small for the number of people using the spa. At busy times, you may need to wait or come back later.

I was generally able to experience everything I wanted, but don’t expect acres of empty spa space.

Don’t Forget the Indoor Minerva Bath

The Minerva Bath is the main indoor thermal pool.

It’s a good alternative when you want a break from the rooftop, particularly if the weather isn’t cooperating.

I personally preferred the rooftop pool because the views are what make Thermae Bath Spa feel uniquely Bath to me.

But having both an indoor and outdoor option makes the experience work regardless of England’s opinions about the weather that day. (And the rooftop spa can get crowded.)

Is a Thermae Bath Spa Treatment Package Worth It?

I booked the Thermae Indulgence package on both visits and chose the Back to Nature treatment, which includes a full-body massage followed by treatments for your hands and feet, a facial and a scalp massage.

The package also includes two hours of spa access and cream tea in the Springs Café.

The therapists themselves were excellent, and I enjoyed the treatments.

But the treatment experience felt somewhat routinized: Several guests began at the same time. There were multiple treatment rooms that looked very similar, and the whole process felt efficient rather than especially intimate or luxurious.

There’s nothing inherently wrong with that. I had good treatments and left relaxed.

But if you’re picturing a highly personalized boutique spa experience where someone knows your name, brings you herbal tea and gives you an entire peaceful room to yourself for half a day, this isn’t quite that.

Thermae Bath Spa handles a lot of people.

You can feel that.

My package also included cream tea at the Springs Café. I could choose a glass of Prosecco, tea or coffee along with a scone served with jam and clotted cream.

Naturally, I chose the Prosecco.

The café also serves cakes, sandwiches, snacks and drinks, and one helpful detail was that time spent in the café wasn’t deducted from my spa session.

You don’t have to carry cash around either. Purchases can be charged to the wristband you’re given when you arrive, which also serves as your locker key.

So, would I pay extra for the treatment package again?

Possibly—but I don’t think you need one to get the best part of Thermae Bath Spa.

For me, the thermal water, rooftop pool and Wellness Suite are the distinctive experience. The treatments were an enjoyable extra rather than the thing that made the spa special.

If your budget only stretches to regular spa access, I wouldn’t feel as though you’re settling for an inferior experience. You’re still getting the part I’d most want to return for.

What I Wish I’d Known Before Visiting Thermae Bath Spa

After two visits, there are a few things I’d particularly want someone to know before booking.

You Won’t Be Taking Pictures Inside

Thermae Bath Spa has a strict no-phone policy. Your phone is placed inside a locking pouch when you enter and stays locked away until you leave.

At first, I was a little disappointed. From a blogging perspective, I would have loved photos.

But it’s also a rule I understand: Nobody was posing for endless photos. Nobody was talking into their phone. Nobody was holding a camera above the water while everyone else tried to stay out of the background.

People were just…at the spa.

It makes the whole experience more relaxing and gives everyone much more privacy.

So while you won’t leave with your own rooftop-pool selfie (and you’ll notice there are few photos in this post), I ultimately think the rule improves the experience.

It Can Get Busy

This is probably the biggest expectation I’d set before you go.

This isn’t a quiet little hotel spa with six guests…Thermae Bath Spa is one of Bath’s major attractions.

There are limits on capacity, and during my visits I saw people having to wait before entering some areas.

The Wellness Suite rooms in particular can feel small when several people want to use them at once.

That didn’t ruin the experience for me. I still found plenty of opportunities to relax.

But expectations matter, so if you go expecting total solitude—especially on a summer weekend—you may be disappointed.

If you go expecting a popular thermal spa in the middle of one of England’s busiest tourist cities, you’ll probably enjoy it much more.

The Layout Isn’t Always Intuitive

This was probably my biggest practical frustration.

For a multi-level spa with several different facilities, I didn’t think the signage was always as clear as it could be.

I spent more time than I would have liked trying to figure out where I was supposed to go, especially in the locker room.

Maybe that’s how I missed the Celestial Relaxation Room the first time.

When you arrive, take a minute to understand the layout instead of doing what I apparently did and assuming I’d figure it out along the way.

Bring a Swimsuit and Pool Shoes

You don’t need much.

Bring a swimsuit, flip-flops or sliders, and whatever you need for showering and getting ready afterward.

A robe and towel are provided.

And while you should obviously bring your phone to Bath, don’t expect to use it once you’re inside the spa.

Book Ahead If Thermae Bath Spa Matters to You

I would.

Standard spa sessions can currently be booked online, and some same-day walk-in spaces may also be released.

But if Thermae Bath Spa is one of the experiences you’re particularly looking forward to, I wouldn’t leave it to chance.

And definitely plan ahead if you want treatments rather than simply spa access–you’ll need to actually call them to book it.

Give It Enough Space in Your Itinerary

Don’t look at a two-hour spa session and assume you only need to block exactly two hours out of your sightseeing day.

You’ll also need to arrive, change, get oriented, shower and get ready again afterward—and you’ll probably want to linger rather than mentally racing toward your next Bath attraction.

This isn’t something I’d squeeze between two other timed admissions.

Give yourself enough space to actually relax.

Thermae also allows additional time for the café and 15 minutes at the end of your session for changing and drying your hair, but I still wouldn’t schedule another timed attraction immediately afterward.

One other thing to know: Thermae Bath Spa is adults only, with a minimum age of 16. You must be at least 18 to book treatments.

Is Thermae Bath Spa Worth the Price?

For me, yes—but I think the strongest value is in the basic thermal-spa experience.

A regular spa session is obviously much less expensive than adding treatments and food, and I’d check current prices directly before your trip because packages and special offers can change.

But you’re not simply paying to sit in a steam room or get into a swimming pool.

You’re bathing in naturally heated thermal water in the center of a city that has built much of its identity around those waters.

That’s what feels special. The treatments are nice, but the setting is what you’re really paying for.

Roman Baths vs. Thermae Bath Spa: Should You Do Both?

Yes. If you have the time and budget, I think they’re better together.

At the Roman Baths, you learn why these waters mattered.

At Thermae Bath Spa, you get to experience them.

The two attractions are completely different, but together they tell part of the same story.

I actually think this is one of the best examples of what I love about Bath. The city doesn’t simply have history—it has a really long history.

Who Will Love Thermae Bath Spa?

I’d particularly recommend it if:

• you enjoy spas and wellness experiences
• you’re interested in Bath’s thermal-water history
• you want something relaxing between days of sightseeing
• you love a rooftop view
• you’re traveling as a couple or on a girls’ trip
• you’ve spent the previous eleven days walking the Cotswold Way and would very much like to sit in warm water

That last one may be a little specific, but I can personally recommend it.

Who Might Want to Skip It?

Thermae Bath Spa may not be for you if you’re looking for an extremely quiet, intimate luxury spa.

It can be busy, some of the Wellness Suite rooms are small, and the overall operation feels more like a major attraction than a secluded spa retreat.

It’s also probably not worth squeezing into an already packed day if you’re only visiting Bath for a few hours.

This is something I’d build into the itinerary rather than rush through.

And if what you really want is an elaborate, highly personalized treatment experience rather than the thermal water itself, I might spend that treatment budget elsewhere.

My Guide: How to Spend Two Days in Bath (COMING SOON!)

So, Is Thermae Bath Spa Worth It?

For me, yes.

I’ve paid to visit twice, and I’d go again.

But I’d go for the thermal water. I’d go for the rooftop pool. I’d go for the Wellness Suite and the opportunity to spend a couple of hours doing almost nothing in the middle of a sightseeing-heavy trip. The treatments were good, but they’re not what makes this place special to me.

What makes it special is the connection to Bath itself.

Bath exists because of these waters.

Romans came here for them. Medieval visitors came here for them. Georgian society built an entire fashionable culture around them.

And now here I was, floating in them too. That’s the experience I’d pay for again.
