So a chance to spend the day there relaxing, beautifying and indulging would make one of the most welcome gifts we can think of for any woman, whether friend, sister or mother.
And now you can present that gift for Christmas with the Winter Bliss Limited Edition Spa Gift Voucher, £176.20 (it's now minus the VAT reduction).
With the voucher you can visit the spa any day of the week and enjoy full use of its wonderful facilities, including the Koi Carp lounge where you can relax between treatments, the Atrium Pool with its fun swing, an exercise pool and spa pools, the sleep retreat, and the heat and sauna rooms.
You'll also enjoy a 50-minute treatment, plus champagne lunch and afternoon tea, as well as a Spa Indulgence Gift Collection worth £20 as a reminder of your day.
It's a great last-minute present, in particular, because you buy it online and print out a voucher to pop under the tree while the real one is sent in the post.
For a taster of the Sanctuary experience, there are plenty of other gift ideas on offer this festive season. We like the Overnight Body Renewal Gift, £14.68, which includes Body Wash, 75ml; Body Scrub, 50ml; Body Butter, 150ml; Foaming Bath Soak, 75ml; Salt Scrub, 60g and a Body Brush all presented in a covetable black wash bag.
