Much like at restaurants and hair salons, the industry standard for tipping at the nail salon ranges around 15 to 20 percent, and it is generally recommended that if you've received extra services or specialty designs, a minimum of 20 percent is appreciated.

Spa manicures provide not just a longer-lasting result, but also an enjoyable experience that can help promote health and well-being. Although there may be some additional cost associated with the extra products and services used during a spa manicure, the overall benefits can outweigh the extra expense.
