40-Piece Hot Stone Massage Set with Basalt, Marble & Bamboo Box

Master Massage 40-Piece Hot Stone Set – Basalt, Marble & Bamboo Box

The Master Massage 40-Piece Hot Stone Set is a versatile professional stone collection for regular full-body hot stone treatments where a compact 18- or 28-piece set no longer provides enough placement and rotation flexibility. The collection combines 38 natural black basalt stones in several sizes and shapes with 2 white marble stones for suitable cool-stone and contrast applications. Large, medium, small, facial and pressure-point stones provide a broader working selection for professional massage practices, spas and wellness treatment rooms.

✔ 40-piece professional stone collection – for regular full-body routines
✔ 38 natural basalt stones + 2 white marble stones
✔ Large, medium, small, facial & pressure-point stones
✔ Useful orientation for approx. 45–60 minute treatments
✔ Smooth shaped and polished working surfaces
✔ Natural bamboo storage box included

Why Choose the 40-Piece Hot Stone Set?

The 40-piece collection represents an important step up from compact hot stone sets because it provides both greater stone quantity and greater stone variety. More large and medium working stones mean more stones can remain available while others are being used for massage or placement. Smaller stones, facial stones and pressure-point stones add additional options for more detailed work. This makes the 40-piece set particularly suitable for therapists who offer hot stone massage as a regular professional treatment rather than only as a short add-on.

Designed for Regular Full-Body Hot Stone Treatments

A practical orientation for this collection is approximately 45–60 minutes, depending on your massage technique, placement pattern, heater capacity and how frequently cooled stones are replaced. The advantage over smaller sets is not simply a longer possible treatment. The additional stones also allow a calmer workflow because some stones can remain warm and ready while others are already in use. Treatment duration should always be treated as a guide rather than a fixed specification. Extensive layouts and frequent stone replacement may require a larger 50-, 60- or 70-piece collection.

38 Natural Basalt Stones + 2 White Marble Stones

The set contains 38 natural black basalt stones. Basalt is commonly used for hot stone massage because its dense volcanic structure absorbs and retains warmth effectively. The collection also includes 2 white marble stones. These are intended for appropriate cool-stone or contrast applications where a therapist deliberately works with a cooler stone alongside warmed basalt stones. Because basalt and marble are natural materials, small differences in colour, grain, surface character and exact dimensions are normal.

What's Included in the 40-Piece Set?

8 Large Flat Oval Basalt Stones

Approx. 7.5 × 5.7 × 2.5 cm each

Broad working and placement stones for larger body areas such as the back and thighs.

16 Medium Flat Oval Basalt Stones

Approx. 6.6 × 5 × 1.8 cm each

Versatile general-purpose stones suitable for areas including the arms, calves, neck and feet.

6 Small Flat Oval Basalt Stones

Approx. 3.8 × 3 × 1.8 cm each

Smaller stones for more compact placement areas such as the forehead, crown and back of the head.

4 Small Circular Facial Basalt Stones

Approx. 2.2 cm diameter × 0.75 cm

Compact basalt stones for suitable facial and other detailed placement work.

4 Pressure-Point Basalt Stones

Approx. 7.5 × 3 × 1.8 cm each

Narrow specialist stones for more focused and controlled massage work, including suitable techniques around the back and neck.

2 Small Oval White Marble Stones

Approx. 4.2 × 3 × 0.75 cm each

White marble stones for suitable cool-stone and contrast applications.

Total: 8 large + 16 medium + 6 small + 4 facial + 4 pressure-point basalt stones + 2 marble stones = 40 massage stones.

More Stone Rotation During the Treatment

Stone rotation is one of the main reasons to choose a larger hot stone set. Heated stones gradually lose warmth during massage and placement, so having additional stones ready can help maintain a smoother treatment flow. With 40 stones available, several stones can remain in the heater while others are being used. This provides more flexibility than compact 18- or 28-piece sets, particularly during regular full-body treatments. The exact number of stones you need heated at the same time depends on your treatment routine and does not necessarily mean that all 40 stones must be heated for every appointment.

Facial, Pressure-Point & Marble Stones Included

The 40-piece collection introduces several specialist stone types that broaden the set beyond standard body-sized oval basalt stones.

• Facial basalt stones provide compact sizes for suitable detailed placement work.
• Pressure-point basalt stones have a narrower shape for more focused manual techniques.
• White marble stones provide an additional option for appropriate cool-stone and contrast routines.

These additional shapes are one of the main functional differences between the 40-piece set and smaller, simpler basalt collections.

28-Piece or 40-Piece Hot Stone Set?

The 40-piece set is the better choice when full-body flexibility and stone rotation become more important than keeping the collection as compact as possible.

Choose the 28-piece set if:
✔ you want a compact professional basalt-only collection
✔ shorter routines are your main priority
✔ easy heating, cleaning and storage are especially important
✔ you do not need marble or dedicated facial stones

Choose the 40-piece set if:
✔ you offer regular full-body hot stone treatments
✔ you want more warm stones available for rotation
✔ facial and pressure-point stones are useful to your workflow
✔ you want two white marble stones for suitable cool-stone work

40-Piece or 50-Piece Hot Stone Set?

Both collections are designed around regular professional full-body use, but the 50-piece set provides additional stones and greater reserve capacity for longer routines.

Choose the 40-piece set if:
✔ approx. 45–60 minute routines cover your main requirements
✔ you want a balanced professional set without excessive stone quantity
✔ easier heating and organisation remain important

Choose the 50-piece set if:
✔ one-hour hot stone treatments are a regular part of your work
✔ you want more stones available for replacement and rotation
✔ you want a broader professional collection with additional specialist stones

Which Hot Stone Set Size Should You Choose?

• 18 stones: Compact collection for shorter or focused routines.
• 28 stones: Compact professional basalt set with several sizes and pressure-point stones.
• 40 stones: Regular professional full-body collection with more rotation, facial stones and two white marble stones.
• 50 stones: Broader professional set for approximately one-hour routines and greater stone reserve.
• 60–70 stones: Extensive collections for longer treatments, spa-style layouts and maximum stone choice.

Stone count should only be the first filter. Always compare the sizes, shapes, materials and heater capacity required for your own treatment workflow.

Choose the Right Hot Stone Heater

A 40-piece set requires more heater space than the compact 18- and 28-piece collections, particularly because it contains 24 large and medium stones. You may not need to heat every stone at the same time, but your warmer should provide enough usable internal space for the working stones and reserve stones required during your treatment. Compare suitable equipment in our Hot Stone Heaters range.
