Truly hidden in plain sight, Madarin Oriental’s Mayfair outpost sits on the corner of Hanover Square – just mere steps away from the hubbub of Oxford Street. You wouldn’t be able to tell once inside though; the hotel’s subterranean spa cocoons guests from the street-level bustle. Here, it’s easy to get lost in the quiet bubbling of the pool, the pleasant thrum of music and the vast assortment of spa amenities – designed by Tokyo based studio Curiosity, visitors can expect all the luxurious modcons – but for a real ‘switch off’ moment, you’ll want to book one of the high tech treatments on offer.

Facilities:

Indoor 25-metre heated swimming pool
Sauna
Vitality pools
Experience showers
Steam rooms
Treatment rooms
State-of-the-art gym

Treatments To Book: On the treatment menu, bespoke rules the day, as do the highest quality brands specialising in science and sustainability – including Swiss Perfection, Seed to Seed Tuscany and OTO.

Best For: A holistic urban retreat

This Roman-inspired wellness hotspot is famous for a reason. The spa at Four Seasons Hotel London at Tower Bridge offers a much-needed refuge in the heart of the adrenaline-fuelled city. Every wall and corner of this spa is smooth and ‘round’ so you don’t feel ‘boxed in’ but are instead curious see what lies around the corner, and the columns around the pool and glistening mosaics are reminiscent of Roman Bath’s and a nod to the building’s grand history. There’s no awkward Jacuzzi sharing with strangers here – it’s huge.

Indoor lap pool
Vitality pool
Sauna
Steam room
Treatment rooms
SAVA Sound Pod
Fitness Centre

The oils will calm you and the therapist will soothe and relax you, talking through your ‘tight areas’ after in a bid to pin down the cause.

And it does what it says on the tin (and some), with a combination of skilful facial massage, cleansing, exfoliating and intense hydrating (where needed) resulting in a quasi-supernatural glow that lasts for days. The 75 minutes whizz by in unadulterated bliss, with a final light head, neck and shoulder massage providing that extra spring in your step as you regretfully re-emerge into the real world.

What To Know Before You Go

When Do Spas Open In London?

This depends on the spa itself. Most spas in the UK capital are not open 24 hours a day, but they’ll usually have daytime (usually from 8am to 5pm) and nighttime hours (usually from 5pm until late) during which you can visit.

Do You Tip?

As a general rule, you are not expected to tip spa therapists in the UK, but you can always double check with the hotel if they have a policy.

Is There An Age Limit?

Generally speaking, no, there isn’t an age limit for guests visiting spas in London. Check policy on child access to a spa if you want to take any little ones with you.

Do You Need To Bring Anything With You?

Most spas will be well-equipped when it comes to facilities, including towels, robes, slippers, shower products and hairdryers. If you’re unsure of what’s included in your spa package, you can always ask your spa for details.

Do You Wear Clothes At The Spa?

Unless stated otherwise, guests are typically expected to wear some kind of clothing while at the spa. A bathing costume and robes are the most common attire, although if you don’t plan to use a pool then comfortable indoor clothing should be fine. You might be required to take some clothing off for treatments.

What Is The Spa Etiquette In London?

Spa guests are typically required to wear bathing costumes or relaxed indoor clothing at all times, as well as robes and footwear in public spaces. This is unless otherwise stated, or receiving a treatment that requires you to disrobe. It’s also advised that guests drink plenty of fluids to stay hydrated, especially if taking part in a thermal spa experience, and not go overboard on the alcohol.

What Is The Difference Between A Day Spa And A Night Spa?

It’s all in the name: day spas operate from morning to afternoon, and night spas operate in the evening. Day spas are the most common type of spa, and will likely stick to daytime hours if they aren’t part of a hotel, while night spas will employ later hours and, if part of a hotel, may also offer packages with an overnight stay.
