## Common ground
All options are types of hip or foot baths categorized by their primary material.
## Options at a glance
**3922.10 – Plastic**
- **Defining trait:** Made from synthetic plastic, typically lightweight and moldable.
- **Typical examples:** Disposable foot basins, molded plastic soaking tubs.
- **Best fit when:** Low cost, portability, or single-use is prioritized.
**6810.99 – Cement concrete or artificial stone**
- **Defining trait:** Constructed from rigid, heavy composite materials like concrete or synthetic stone.
- **Typical examples:** Heavy-duty foot baths in spas or industrial settings.
- **Best fit when:** Durability and permanence are key (e.g., commercial use).
**6910 – Ceramic**
- **Defining trait:** Made from fired clay, often glazed for water resistance.
- **Typical examples:** Traditional porcelain foot basins, decorative baths.
- **Best fit when:** Aesthetic appeal, heat retention, or classic design is desired.
**7324.2X – Stainless steel**
- **Defining trait:** Corrosion-resistant, durable metal with a polished finish.
- **Typical examples:** Medical or spa-grade foot baths, hygienic environments.
- **Best fit when:** Hygiene, longevity, and resistance to wear are essential.
**7324.90 – Iron or steel**
- **Defining trait:** Made from uncoated or basic steel, often prone to rust.
- **Typical examples:** Industrial foot baths, older models without protective coating.
- **Best fit when:** Low cost and simple construction are priorities (but not long-term use).
**7418.20 – Copper**
- **Defining trait:** Made from natural copper, known for antimicrobial properties.
- **Typical examples:** Luxury or therapeutic foot baths in wellness centers.
- **Best fit when:** Health benefits (e.g., antibacterial) and premium appearance are valued.
**7615.20 – Aluminium**
- **Defining trait:** Lightweight, non-rusting metal with good heat conductivity.
- **Typical examples:** Portable foot baths for travel or home use.
- **Best fit when:** Light weight and quick heat transfer matter (e.g., hot water use).
**7907.00 – Zinc**
- **Defining trait:** Made from zinc, often used in galvanized coatings but rare as a primary bath material.
- **Typical examples:** Very niche or decorative foot baths; not common.
- **Best fit when:** Unusual design or protective coating (e.g., galvanized finish) is intended.
## Key differences
| Material | Weight | Durability | Heat retention | Common use |
|------------------|----------|------------|----------------|------------------|
| Plastic | Light | Low | Poor | Disposable, home |
| Concrete/stone | Heavy | High | High | Permanent, spa |
| Ceramic | Medium | Medium | High | Decorative, home |
| Stainless steel | Medium | Very high | Medium | Medical, spa |
| Iron/steel | Medium | Medium | Medium | Industrial |
| Copper | Medium | Medium | High | Luxury, therapy |
| Aluminium | Light | Medium | High | Portable, travel |
| Zinc | Medium | Low | Medium | Niche, decorative|
## How to choose
- Is the bath lightweight and portable? → 3922.10 or 7615.20
- Is it meant for permanent installation or heavy use? → 6810.99 or 7324.2X
- Does it have a classic, decorative look? → 6910 or 7418.20
- Is hygiene and corrosion resistance critical? → 7324.2X
## Overlaps & pitfalls
A bath may combine materials (e.g., stainless steel with plastic parts), but the primary material determines classification. Zinc is rare—ensure it's not a galvanized coating. If multiple traits apply, prioritize the **main structural material**
