How To Make A Reservation

Cancellation Policy

Spa - We ask guests to guarantee all reservations with a credit card. This card will not be charged unless you cancel or change without giving us adequate notice. For baths and treatments, we require 24 hours notice to cancel or change without a penalty.

Lodging :

  • Cancellations 8 or more days prior to the reservation will not be charged.
  • Cancellations or changes 2-7 days prior will be charged for the first night. 
  • Cancellations or changes after 4pm on the day before check in will be charged for the entire stay. 
  • Those who can provide proof of a positive COVID test are exempt from cancellation fees. The positive test may be for one of your party, a household member, or someone you work closely with that requires your absence from work.

Massage and Spa Services:

On the day of service, you must bring both:

  • a CDC COVID-19 Vaccination Record Card showing complete vaccination at least 14 days prior to date of service AND
  • a photo ID
  • Failing that, 100% of the massage fee will be charged.


Alcohol & Beverages

Heat and high altitude will exacerbate the effect of alcohol (or any form of psychoactive substance, even coffee). Impaired judgment and loss of consciousness can result. Because of this, we strongly discourage the consumption of alcohol before or during activities at the Waves. If you do bring glass containers, please inform us upon check-in so that we can provide a bottle caddy and/or non-breakable cups. Glass, hard floors, and bare feet are a bad combination.

Children & Under 18

At Ten Thousand Waves, we are inclusive, not exclusive. We welcome well-behaved children in our lodging rooms and baths.  There is no charge for children under 4 feet in any private tub (2 kids maximum per adult). Anyone under the age of 18 must have the permission of an adult to use our facilities.  


Food & Drink

Our great Japanese restaurant izanami is open every day. See hours Drinks, but not food, may be taken into hot tub areas. Consumption of alcohol before or during bathing is not advised.

Health Concerns

Hot water and sudden temperature changes can be stressful to your body. If you are pregnant or have chronic health problems, always consult your health care provider before bathing.

If you have recently been exposed to COVID or come from a region where the infection rate is high, we would suggest waiting 14 days before visiting.

Nudity / Bathing Suits

All private spa suites are clothing optional. Swim suit bottoms are required in the Grand Bath. Please feel free to wear suits in any of the facilities. (Suit rentals available at the front desk for $4.00, tax included)

Therapeutic Massage is done without clothing. Our therapists are specially trained to drape discreetly with sheets and towels. Shiatsu massage and Ashi Anma Foot massage are done wearing loose clothing. These treatments may be a better option for the modest.


There is plenty of parking at street level, and limited additional parking at the spa level, approximately 60 vertical feet higher. Those with physical limitations should consider the upper lot. The walk from the lower lot, however, is very pleasant and provides a good transition from your busy day to the tranquility of Ten Thousand Waves. Passengers may be dropped off at the entrance to izanami or the spa. There are two accessible spots very close to the spa front door and two spots near izanami.  


Special Needs

A number of our massage rooms, baths, and lodging rooms can accommodate individuals with mobility issues. Unloading and loading of guests may be done in front of the main entrance to the spa or the restaurant, adjacent to which are accessible parking spaces. We have eight private gender-neutral changing rooms, providing a new level of comfort for those who have been hesitant to use a public locker room.

The spa has 3 levels. An elevator is available if stairs are a challenge

Please mention any mobility issue when making your reservations.

Water Cleanliness

We use a state-of-the-art purification system for all baths, utilizing ultraviolet light, hydrogen peroxide, and ozone. Chlorine is not used in any bath. The entire water content of each tub passes through the sanitation system every twenty minutes. We perform bacterial cultures weekly on all tubs to ensure that all systems work properly. Often the result is drinking water quality. See 'Keeping Our Water Clean' for a description of what we do to assure absolutely clean and sanitary conditions.The source of the highly mineralized water used in the baths is a 900-foot deep well.

What To Bring

Here, as in Japan, we ask you to take a shower prior to entering the baths or treatments. This maintains the quality of our water, makes treatments a good experience for guest and therapist, and allows you to rinse off the cares of your everyday life before your experience at the Waves.

You should bring:

  • Yourself--ready for relaxation
  • Your own facemask

We provide, at no charge:

  • Kimono (if receiving both tub and massage)
  • Sandals
  • Towels
  • Shower gel
  • Shampoo
  • Conditioner
