17 L Hot Stone Heater – XL Digital Stone Warmer

Master Massage 17 L Hot Stone Heater – XL Professional Stone Warmer

The Master Massage 17 L Hot Stone Heater is the large-capacity choice for professional therapists, massage practices, spas and wellness treatment rooms that work with larger hot stone sets and need more stones ready at the same time. With an approximately 17 L / 18 qt removable reservoir, digital temperature control and a current-and-target temperature display, this XL stone warmer is designed for full hot stone routines and professional treatment workflows where a compact heater may provide too little capacity.

✔ 17 L / 18 qt XL capacity – for larger professional hot stone sets
✔ Approx. 100 massage stones – exact quantity depends on size, shape and mix
✔ Digital current + target temperature display
✔ Adjustable up to approx. 70 °C / 160 °F
✔ Removable inner reservoir – easier filling, emptying and cleaning
✔ Stone ladle included

Why Choose the 17 L Hot Stone Heater?

The main advantage of the 17 L model is capacity. Professional hot stone routines often use a mixture of large placement stones, medium massage stones and smaller specialist stones. A larger reservoir gives you more space to prepare a comprehensive working set without packing the heater as tightly as a compact unit.

This can be especially useful during longer treatments or when you want additional stones available during the session. The 17 L heater is therefore particularly suitable for massage practices, spas, wellness centres and fixed treatment rooms where hot stone massage is offered regularly.

Digital Temperature Control with Current & Target Display

The digital control panel displays both the current temperature and the selected target temperature, making the heating process easier to monitor during preparation and professional use.

The current manufacturer specification states an adjustable maximum temperature of approximately 70 °C / 160 °F. The display can be switched between Celsius and Fahrenheit.

Important: the displayed water temperature does not automatically represent the exact temperature of every individual massage stone. Always check each stone carefully before placing it on or using it against the client's skin.

How Many Hot Stones Fit in the 17 L Heater?

Master Massage specifies a capacity of approximately 100 massage stones. Depending on the size, shape and combination of the stones being used, the manufacturer also describes the 18 qt reservoir as suitable for approximately 100–120 stones.

The exact number is therefore not fixed. Large body and placement stones occupy substantially more space than smaller treatment, toe or specialist stones.

Removable Reservoir for Easier Daily Handling

The inner water reservoir can be removed from the electrical base, making it easier to fill, empty and clean after use. The outer housing is made from stainless steel and the lid from aluminium, giving the heater a clean professional appearance suitable for treatment rooms and spa environments.

A stone ladle is included to help remove heated stones from the water without reaching directly into the reservoir.

17 L or 6 L Hot Stone Heater?

Neither size is automatically better. The correct choice depends mainly on the number of stones you normally need ready at the same time.

Choose the 17 L heater if:
✔ you use a larger professional hot stone set
✔ you regularly perform full-body hot stone treatments
✔ you want more reserve stones available during a session
✔ treatment-room space is less important than capacity

Choose the 6 L heater if:
✔ you use a smaller working stone set
✔ your treatment-room space is limited
✔ you prefer a more compact heating setup
✔ you do not regularly need a large number of stones ready

17 L Heater or MultiStation?

The 17 L heater and the Master Massage MultiStation serve different professional workflows.

• Choose the 17 L heater when your priority is maximum stone capacity in one dedicated warmer.
• Choose the MultiStation when you regularly use both hot stones and warmed massage oils or lotions and want several separately controlled heating zones in one treatment-room station.
