There are several types of spas:

• day spa;
• salon/spa;
• destination spa;
• resort spa;
• hotel spa;
• club and medispa.

The day spa offers spa treatments, such as massages, facials and body treatments, on a day-use basis. Most offer manicures and pedicures as well. Many hair salons have added day spas, which allow you to combine spa and beauty services in one day.

Facilities will vary at day spas, but most have treatment rooms, a mediation or waiting room, and a locker room with showers. A "wet room" is a tiled room with special shower facilities for more elaborate body treatments. Hydrotherapy tubs are not that common at day spas, but desirable.

The Destination Spa offers a complete spa experience in an overnight setting (most require a two or three-night minimum stay.) Its sole purpose is to provide mind and body fitness, healthy eating, spa treatments and relaxation.

There is a great range in terms of size, style and luxury, but the facilities should be more elaborate and extensive than the average days spa.

Ideally it will have hydrotherapy tubs, wet rooms, steambaths, saunas and some unusual treatments. Expect a wide selection of exercise and stress reduction classes, as well as outdoor activities. It should have gyms for working out, swimming pools, tennis courts, and sometimes Pilates studios. Classes and lectures are part of the programming. Healthy spa cuisine is generally included in the price. While some treatments are included, you will probably want additional services. Some destination spas allow non-guests to book services on a day use basis. Others are limited to guests.

The Resort Spa is a facility that is just one of the many guest amenities at the resort, not the sole or primary attraction. This can be a good choice when one person loves spas and the other loves golf. Check your package: treatments and exercise classes may not be included. Meals are almost certainly a la carte. While there will be some spa cuisine, you can wash down your steak with a bottle of wine. (Some destination spas forbid alcohol.)

The Club spa is attached to a fitness club, and the Hotel Spa is generally a luxury facility attached to an upscale urban hotel. Finally, the medispa has been popping up in large cities. It offers treatments that require a doctor's supervision, such as laser resurfacing and Botox injections, in addition to traditional spa services.

What Is A Spa, Anyway?

The word spa conjures up images of mud baths and meditation classes, spa cuisine in a serene desert setting.

But spas, lately, seem to be popping up everywhere: office buildings, strip malls, village storefronts. Salons and Korean nail places throw the word around. How can they all be spas?

First, there are different kinds of spas. At a destination spa, the whole environment is geared toward the four cornerstones of a spa experience: mind and body fitness, healthy eating, relaxation and treatments. You generally go there for at least two or three nights and immerse yourself in the spa atmosphere. Some people go to help them make lifstyle chnages. The destination spa is sometimes confused with a resort spa, which is one of the many amenities at a resort, along with golf, tennis and as much fatty food as you feel like eating.

But no one is regulating use of the word spa. That's why some salons promote spa services when all they have is one massage table, or use names like "spa pedicure." If you have any doubt, check out the facilities yourself before booking an appointment. Just drop in and ask for a quick tour.

At a minimum, a day spa should offer professionally administered massages, facials and body treatments in a quiet, serene atmosphere. At its most elaborate, a destination spa like Canyon Ranch has a staff of physicians, psychologists, nutritionists and physical therapists. It offers so many classes, lectures and services that and so many things going on that you could spend months there and still not experience them all.

What does it mean? It's up to you, the spa-goer to figure out what kind of service and experience you want, and find the place that suits you.
