A day spa is a business which provides a variety of services for the purpose of improving health, beauty and relaxation through personal care treatments such as massages and facials. A day spa is different from a beauty salon in that it contains facilities such as a sauna, pool, steam room, or whirlpool that guests may use in addition to their treatment. A day spa is different from a destination spa as no overnight accommodation is provided. In contrast, a destination spa offers similar services integrated into packages which include diet, exercise programs, instruction on wellness, life coaching, yoga, Tai Chi and accommodations where participants reside for the duration of their stay. A resort-spa may also function as a day spa, if they allow access to patrons who are not guests of the hotel.
