The ‘Lavender Rain’ water treatment (£98) at this hotel is simply exceptional. Exfoliation is followed by being smothered in oils, wrapped in warm towels… and then a powerful deluge of scented rain pours over you. It feels as if every care and crinkle is being smoothed away. Kohler are water specialists, and this enterprise (their only one outside the States) is worth a detour, or persuading your other half that you’ll be fine entertaining yourself (with a wide choice of water-based and/or sumptuous facial treatments) while they play a round of golf on the famous attached course.
