The main aim is practicality and comfort when you're staying at a spa hotel, so loose-fitting, casual clothing is recommended. While you'll likely spend much of your time in little more than a fluffy robe, these are often given to guests when they arrive. If you want to make the most of the fitness facilities, pack your sportswear and trainers. Hoping to kick back and unwind in the hot tub or steam room? Don't forget to pack your swimming suit. In addition to toiletries and other essentials, bring a change of clothes with you too. It's nice to have something clean and dry to put on after a massage or swim.
