Can I ask for a gentle scrub?
Yes. Ask before the scrub begins and again if the pressure feels too strong. Buying a package does not mean agreeing to uncomfortable pressure.

What is a kese scrub?
A kese is a textured mitt used to exfoliate the skin during the bath. Ask for lighter pressure if needed; discomfort is not something you have to endure.
Can I stop a hamam treatment halfway through?
Yes. Say “stop” clearly and ask the attendant to pause. You do not need to finish a treatment that makes you uncomfortable.
How do I explain my boundaries to the attendant?
State your preferred coverage, pressure and any areas you do not want treated before starting. You can change your mind or ask to pause at any time.
