The Spa at The Newt in Somerset

The one thing

Before the Spa Garden Signature Massage begins, a therapist hands over a wicker basket and walks out with each guest into the spa's own Medieval Herb Garden to cut whatever looks best that morning, mint and calendula, fennel and lemon verbena among them, and those same stems come back indoors to be worked into the massage, steeped into the footbath and poured afterwards as tea in the lounge. No other British spa grows its treatments outside the door like this, and it turns ninety minutes on a table into something closer to a harvest.

The verdict

The Newt is what happened when Koos Bekker and Karen Roos, the couple behind Babylonstoren in the Cape winelands, bought the old Hadspen estate near Bruton and spent six years rebuilding it around a single idea, that growing things and eating things and resting well are all one subject. The gardens came first, reimagined by Patrice Taravella around the Parabola, a walled garden planted as a maze of four hundred and sixty trained apple trees, and everything else follows their lead: a cyder press fed by the orchards, a working farm feeding the restaurants, a museum of gardening, a recreated Roman villa complete with its own working Roman baths, and a bee house with its own architecture award. It is less a hotel with grounds than an estate that happens to sleep forty.

The spa sits in a seventeenth century farm building in the Stable Yard, and the conversion is quietly beautiful, exposed beams and textured stone, herringbone brick underfoot, and a vaulted hall holding the hydrotherapy pool, which slips through glass doors to a second pool outside facing the herb garden. The scale is deliberately intimate. This is not a thermal palace, and it does not want to be one; it is a farm building that bathes people, sitting inside one of the most complete estates in England.

What a night here folds in is the real story. A stay comes with the spa, breakfast, a cream tea and a daily programme of yoga, Pilates, breathwork and sound healing, so it becomes a loose wellness retreat without anything being sold as one. The wider estate does the rest, being gardens to walk until the legs give out, a museum to stand in when it rains, and cyder to taste at the end of it. The World Spa Awards named this the world's best country house hotel spa in 2025, the same year the hotel took its third Michelin Key, and the claim survives contact with the place.

The catch, and it is a real one, is the door. The spa belongs to hotel guests and, on weekdays, to Newt members on booked spa day packages. There is no public spa day at all, so the way in is a night's stay or a garden membership and a little planning.

The water

The pool hall is the heart of it, a vaulted space where the hydrotherapy pool sits under old beams and then continues through glass doors into the open air, so a swim starts in candlelit calm and ends looking at rows of medieval herbs. Around it the circuit stays small and warm: a sauna with a garden view, a marble steam room, a halotherapy room lined with salt, and below, a traditional Turkish style hammam where scrubs and soap rituals are taken on the hot stone. A private Rasul chamber takes couples for mud rituals, rosemary scented in a nod to the Romans who bathed on this land two thousand years ago. In summer the water grows wilder, with guided swims in the estate lake and a weekly cold water dip on the class schedule, and that is the cold offer here, the lake rather than an ice fountain. Families get the pool to themselves for an hour three times a day, and the Farmyard keeps a second indoor pool where children are welcome all day.

Treatments

The treatment menu is built with Seed to Skin, the Tuscan skincare house from the Borgo Santo Pietro estate, which is a natural marriage, one farm's botanical laboratory serving another farm's spa. The signature is the Spa Garden pair, a massage or a body and face treatment of a full ninety minutes, each starting with that walk through the herb garden. The hammam carries its own menu of Moroccan and Turkish rituals, rising to a two hour top to toe scrub, soap and massage, and the private Rasul chamber takes couples for their mud ritual side by side. Beyond the signatures the range runs from herbal poultice, Swedish and deep tissue massage through reflexology, facials and a jetlag remedy, with therapists trained across Ayurvedic practice, Indian head massage and Reiki, and mothers to be are looked after from the second trimester. Booking is charmingly analogue, by email or by dialling zero from a room.

Getting in

Hotel guests have the spa from eight in the morning until eight at night, with treatments bookable until close. Everyone else comes through membership: Newt members can book one of three weekday spa day packages, from a gentle half day to the full Signature day, each including breakfast at the Garden Cafe and a two course lunch in the Botanical Rooms, and each member may bring one guest onto a package. Membership itself is the estate's garden membership rather than anything grander, so a determined spa lover within reach of Bruton has a genuine route in. Spa days run by enquiry rather than instant booking, so plan ahead. Castle Cary station is under ten minutes away with direct trains from London Paddington, Bristol Airport is about an hour by road, and the estate keeps two helipads for those arriving from above, with a day's notice.

What to know before you fall in love

• There is no public spa day, so the way in is a night's stay, or a garden membership plus a weekday package booked by enquiry.
• Member spa days run Monday to Friday only, and weekends at the spa belong to hotel guests.
• This is not an adults only spa. Families have the pool from nine to ten, one to two and four to five each day, and the Farmyard pool all day, so anyone chasing total silence should swim around those windows.
• The thermal circuit is intimate by design, one sauna, one steam room, the hammam and the salt room, so a lover of vast thermal mazes should size expectations to a beautiful farm building.
• Dogs stay at home, assistance dogs aside, because this is a working farm with deer and fowl.

Best for

Garden lovers above all, because nowhere else in Britain does the spa and the landscape belong to each other so completely. Couples building a slow weekend around eating, walking and bathing rather than a treatment marathon. And Somerset members with a weekday free, who reach one of the finest spas in Britain through nothing more than a garden membership.
