Should you tip your massage therapist? And if so, how much? Tipping is a personal choice, but understanding factors like whether your therapist is self-employed or working for a spa can help guide you. While 15–20% of the service cost is a common benchmark, there are many ways to show appreciation—like leaving a positive review or referring friends. Ultimately, the best tip is recognizing their dedication to your wellness, whether through a monetary gesture or heartfelt thanks.
