SenSpa Himalayan Bath Salts
We're big fans of SenSpa's spa-inspired products: pampering at pocket-money prices. (Exclusive to Waitrose, FYI, though there is a real SenSpa, at Careys Manor in Brockenhurst.) We're big fans of salt baths, too, which help relax muscles and soothe aches and pains (for instance, from gardening - or in Sarah's case, horse-riding!)
The bonus with these is they smell great, too, thanks to essential oils of rose, cedar wood and lavender. And they're packed with minerals and trace elements - 84, in all, including potassium, magnesium, iron, calcium and more, which are activated when mixed with warm water.
Simply pour into the tub, lie back and wallow. (But can we recommend not taking a book...? These may be inexpensive, but they're so effective we're not sure Jo's copy of Elizabeth Jane Howard's Casting Off will recover from its dunking...)
UK readers find SenSpa Himalayan Bath Salts at Waitrose stores/from £5.95 for 500 g
