18-Piece Natural Basalt Hot Stone Set with Bamboo Box

Master Massage 18-Piece Natural Basalt Hot Stone Set with Bamboo Box

The Master Massage 18-Piece Hot Stone Set is a compact collection of 100% natural black basalt massage stones for focused hot stone treatments, shorter routines and therapists who do not require a large full-body stone collection. With 6 large and 12 medium flat oval basalt stones, the set concentrates on two versatile working sizes rather than numerous specialist shapes. It is particularly practical for shorter applications, selected body areas or as an additional stone set alongside an existing professional collection.

✔ 18 natural basalt massage stones – compact and easy to organise
✔ 6 large + 12 medium flat oval stones
✔ Ideal for approx. 20–30 minute routines depending on treatment setup
✔ Smooth polished surfaces for massage movements and suitable placements
✔ 100% natural black basalt
✔ Natural bamboo storage box included

Why Choose the 18-Piece Hot Stone Set?

The strength of the 18-piece collection is its simplicity and versatility. Instead of combining many specialised shapes, it focuses on two frequently used oval stone sizes that can be used across several larger and medium-sized body areas. This makes the collection easier to prepare, organise, heat, clean and store than substantially larger 40-, 50-, 60- or 70-piece sets. It is therefore particularly suitable when hot stone massage forms only part of a treatment, when selected body areas are being worked on or when additional working stones are required alongside an existing collection.

Designed for Shorter & Focused Hot Stone Routines

Master Massage positions the 18-piece collection for approximately 30-minute massage and wellness routines. In practice, around 20–30 minutes is a useful orientation depending on treatment technique, stone placement and how frequently warmed stones need to replace stones that have cooled. Compared with a large professional collection, fewer reserve stones are available for continuous rotation. The 18-piece set is therefore better suited to focused applications than extensive full-body layouts requiring a large number of stones throughout the session. Treatment duration is only a practical orientation. Actual stone requirements depend on individual working method, heater capacity and the number of stones being used simultaneously.

18 Natural Basalt Massage Stones

All 18 stones are made from natural black basalt. Basalt is widely used for hot stone massage because its dense structure is suitable for absorbing and retaining warmth. The stones are shaped and polished to provide smooth working surfaces suitable for massage movements and appropriate placements. Because basalt is a natural material, small differences in colour, grain, surface character and exact dimensions are normal and do not represent a product defect.

What's Included in the 18-Piece Set?

6 Large Flat Oval Basalt Stones

Approx. 7.5 × 5.7 × 2.5 cm each

These larger stones provide a broader contact area and are particularly useful for larger body areas such as the back.

12 Medium Flat Oval Basalt Stones

Approx. 6.6 × 5 × 1.8 cm each

The medium stones provide a versatile working size for several body areas. The manufacturer's suggested distribution includes stones for the arms, thighs and neck area.

Total: 6 large + 12 medium = 18 natural basalt massage stones.

Natural Bamboo Storage Box Included

The complete collection is supplied in a natural bamboo storage box, helping to keep all 18 stones together and organised between treatments. After use, clean the stones according to your professional hygiene procedure and allow them to dry completely before returning them to the bamboo box.

18-Piece or 28-Piece Hot Stone Set?

The right set depends less on the headline stone count than on the range of stone sizes and the type of treatments you perform.

Choose the 18-piece set if:
✔ you want a compact selection of large and medium basalt stones
✔ you mainly perform shorter or focused hot stone routines
✔ you want supplementary working stones for an existing set
✔ simple preparation and compact storage are important

Choose the 28-piece set if:
✔ you want a broader selection of stone sizes
✔ you want additional specialist pressure-point stones
✔ you regularly perform longer hot stone routines
✔ greater placement and stone-rotation flexibility is important

Which Hot Stone Set Size Should You Choose?

• 18 stones: Compact selection for shorter routines, focused body areas and supplementary use.
• 28 stones: Broader compact professional set with more sizes and specialist stones.
• 40–50 stones: More flexibility for regular full-body layouts and greater stone rotation.
• 60–70 stones: Extensive collections for longer routines, larger layouts and maximum stone availability.

The number of stones is only one factor. Always compare the actual stone sizes, shapes and composition of each set before choosing.

Choose the Right Hot Stone Heater

For hot stone massage, the basalt stones should be heated using a suitable temperature-controlled professional stone warmer. The compact 18-piece collection requires less heater space than the larger 50–70 piece sets and can therefore be a practical choice when heater capacity or treatment-room space is limited. Always check the usable internal dimensions of your warmer rather than relying solely on its nominal litre capacity.
