A standard bath salt recipe is roughly 97–98% salt base with 1–2% essential oil and optional colorant. The salt base itself can be a single type or a blend of Epsom, Dead Sea, and Himalayan salts.
Use 0.5–2% essential oil by total weight. For an 8 oz jar, that is 8–16 drops for light scent or 25–30 drops for strong scent. Always blend with dendritic salt or carrier oil first to distribute evenly.
DIY bath salts cost $0.40–$1.50 per 8 oz jar depending on salt type and essential oil choice. Epsom salt is cheapest at ~$0.04/oz; Dead Sea salt runs ~$0.12/oz. Essential oils are the biggest cost driver.
| Salt Type | Cost per oz | 8 oz Jar Cost | Retail Price |
|---|---|---|---|
| Epsom | $0.04 | $0.40–$0.60 | $6–$8 |
| Himalayan | $0.08 | $0.70–$1.00 | $8–$12 |
| Dead Sea | $0.12 | $1.00–$1.50 | $10–$15 |
Epsom salt is the most popular base for muscle-soothing baths, while Dead Sea salt offers the most minerals for skin care. Many crafters blend 70% Epsom with 20% Himalayan and 10% dendritic for color and scent retention.
