To redeem a Tattva Spa gift card for a birthday gift for your husband, begin by checking the validity and balance of the voucher. Then, visit the Tattva Spa website or contact their customer service to locate the nearest spa location. Once you’ve chosen the spa, book an appointment for your husband’s desired service, whether it’s a relaxing massage, rejuvenating facial, or any other spa treatment. During the booking process, enter the gift card code for payment. On the day of the appointment, ensure your husband brings along the physical or digital copy of the spa gift voucher. At the spa, he can enjoy a pampering experience, courtesy of your thoughtful birthday gift. It’s a wonderful way to show your husband how much you care about his well-being on his special day.
