One Spa Edinburgh

The lowdown

One Spa has won numerous awards since it opened over twenty years ago, and it’s had multiple upgrades since then, keeping up with the latest spa trends and customer wellness wants. It’s no stranger to the title of Best Spa in Scotland and it’s the country’s best known urban spa. As it’s on the top floor, it’s a light and bright space and has a popular rooftop hydro pool – perfect for kicking back in and enjoying some Scottish sunshine. While the spa does have signs designating a ‘quiet zone’, there can be dozens of spa guests using the extensive spa space at any one time, so it’s not your strictly silent type of spa, making it a good option for friends, couples and groups.

You don’t have to be staying at the hotel to visit the spa as it has plenty of day spa packages, including the popular signature Escape at One spa which gives you 3 hours’ access to the pools and Thermal Suite.

If you want to use the wider hotel facilities, there’s a contemporary Scottish restaurant, One Square brasserie, and a lively bar with a particularly impressive gin menu.

There’s also a decent and daylight-filled gym with Technogym equipment and a movement studio.

Spavellous for

Groups, couples, a city spa break, hen parties, corporate spa break or a solo spa day or stay.

Spa info

The spa is large, with a 19m indoor pool and an impressive 12 different thermal and spa experiences where you can relax, sweat, chill and stimulate mind and body. One Spa has 16 treatment rooms too, offering everything from luxurious facials to indulgent top to toe treatments by ESPA and Temple Spa.

Spa guests who’ve booked the signature Escape at One, which allows access to the pools and all the spa facilities including the Thermal Suite, are given a wrist band to wear during their visit. Hotel guests can access the pool area and poolside sauna, but need to pay extra if they want to access the rest of the spa facilities.

The extensive Thermal Suite at One Spa Edinburgh includes:

Rooftop hydropool – bubbly al fresco R&R accessible via the indoor hydropool

Crystal Steam Room – humid and aromatic with an amethyst crystal

Hammam – a hot and steamy refuge with mosaic benches. Good for getting a sweat on

Laconium – a dry heat experience with warm mosaic benches

Bio sauna – a gentle heat with aromatic essences

Rock Sauna – a hotter sauna with twinkly lights

Tepidarium – more cosy than hot, an inviting place to relax on the warm tiled loungers

Deep Relaxation Room – does what it says on the tin, with low lighting and a relaxing fire

Himalayan Dry salt room – with heated recliners and a button that releases a fine saline mist to aid healthy breathing

Quiet Relaxation Room – pretty in pink with plenty of loungers

Ice Fountain – ice flakes to massage into your skin for use in contrast therapy

Experience showers – with tropical rain, storms and cold mist setting

There are helpful instructions by each feature, giving guidance for use and suggestions for combining heat experiences, order of visit, and the optimum time to spend in each one.

The spa is open from 6.30am-10pm Monday to Friday and 7am-9pm Saturday & Sunday.

Children can use the pool weekdays from 8:30-9:30am and 4-5pm. And at weekends between 8:30-9:30pm and 3-5pm.

Treatment highlights

One Spa has a comprehensive spa treatment menu featuring facials, full body massages, head massage, scrubs, wraps, reflexology and pregnancy treatments.

Temple Spa bestsellers include the luxurious Champagne and Truffles Deluxe Treatment, their Rose Quartz and Truffle Body Massage and the All About the Glow Facial.

ESPA favourites include their personalised Inner Calm Full Body Massage, the Hot Stone Therapy Full Body Massage and the hydrating Inner Beauty Facial.

One Spa’s treatment area has a calming feel and offers a relaxing experience from the second you reach the waiting area until the last sip of your Wellbeing Tea in the Relaxation Room. As there are 16 treatment rooms, One Spa’s a great choice for a sophisticated hen activity or birthday celebration and offers packages for groups of five or more, with food and refreshments included.

I was booked in to try the ESPA top-to-toe Signature at One treatment, a 90-minute ESPA treatment which combines an exfoliating scrub with a hot stone massage, an express facial and a head massage. It sounded like a perfect combination.

I was collected from the treatment waiting area and led down the curtained corridor to a candlelit treatment room. A cosy room, with dark wood panelled walls, it has a wide and comfortable-looking massage table in the centre and pretty starburst ceiling lights. It also has its own shower.

Before the treatment started, my therapist gave me two scent tests – one for the facial toner and one for the body oil. I chose the Balancing Herbal Spa-Fresh toner and the Restorative oil, both containing Rose Geranium, with the latter being described by the therapist as ‘a hug in a bottle.’ She also gave me some disposable paper knickers, in case I was worried about getting scrub on my underwear, unaware that rule number one of Spavellous is ‘carry spare knickers and an extra cozzy at all times.’

The treatment started with some soothing, and occasionally mildly tickly, body brushing, and the application of ESPA’s Relaxing Salt Scrub. The therapist worked the scrub down one side of my body at a time, leaving the other covered, waking up my skin as she went. Once she’d completed the scrub part, she carefully manoeuvred a towel around me, to protect my modesty, and left the room while I washed off the scrub in the ensuite shower. Once I’d dried off, I ensconced myself back on the comfy warm bed, face down and ready for the massage.

Next up was a particularly relaxing hot stone massage. It was a slow-paced aromatherapy style massage, designed to soothe and relax rather than target any specific muscle tension. The therapist paid particular attention to my upper back and shoulders as I’d requested. The flowing, sweeping motion was thorough and unhurried and, combined with the warmth, left me on the verge of sleep.

Next came the facial part where my skin was thoroughly cleansed, toned and moisturised. I found the facial particularly pampering and was pleased with my choice of toner, with its fresh and uplifting scent.

Finally, I was treated to a fabulous head massage – a soothing finale that put the icing on the super-relaxing cake.

Once I was back in my robe, the therapist led me in my blissed-out state to the Relaxation Room where I snuggled under a blanked on one of the loungers, sipped apple and berry tea and watched the twinkly ceiling lights.


The 269 bedrooms have a contemporary corporate feel, with the occasional pop of colour and Laird-look linen. Book a Castle-facing room for full Edinburgh vibes.

wining & dining

The Sheraton Grand has its own restaurant, One Square, serving elevated brasserie food with a suave Scottish lilt. If contemporary Scottish dining doesn’t tickle your tastebuds, there are plenty of other restaurants, bars and cafes to try nearby. If you do decide to dine at the hotel, grab yourself one of the coveted tables overlooking Edinburgh Castle and enjoy a G&T with One Square house gin, made by local distillery Pickering’s.

why so spavellous?

One Spa is a decent option if you’re looking for a city spa day or spa break. It offers a varied spa experience making it a good choice for a couples’ break, solo spa escape or group spa experience.

The Thermal Suite has a great range of facilities and there’s a good variety of treatment options too. The Signature treatment I had was top notch. There are spacious changing facilities, and lockers with robes and slippers are provided. Staff are friendly and helpful, and the spa’s in a convenient location if you want to make the most of exploring Edinburgh.

spavellous tips

If you’re staying at the hotel, book a castle view room for maximum Edinburgh vibes.

Head to the hydro pool just before dusk to enjoy the changing city lights.

If you’re looking for peace and quiet, try to avoid peak times in the spa when it can get quite busy.
