New Zealand brand Kereru also sells bath salts. They are available in Body Revive (Pine, Lemon, Majoram and Rosemary), Pamper (Rose Geranium), Passion (Orange, Patchouli and Ylang Ylang), Sweet Dreams (Lavender and Mandarin), and Vitalise (Lemon and Lime). They cost $4.50 for 125g, and $8 for 300g. Kereru products are available at Commonsense Organics.
If you prefer a bath milk, you could try one of Weleda's. There is Citrus Bath Milk, Lavender Relaxing Bath Milk, Pine Reviving Bath Milk, and Rosemary Invigorating Bath Milk, all $26.90 for 200ml. Weleda also has a Wild Rose Cream Bath, $31.40 for 100ml.
If you want a bubble bath, there's Bod for Bubs Bubble and Squeakie Clean. Yes, it's intended for babies, but there's no reason why adults can't use it, I guess! Another baby bath product is Ecostore Sleepytime Bath, $10.95 for 200ml, available at Commonsense Organics, Health 2000, Woolworths, Foodtown, Pak N Save, New World, Homestead Health, and Hardy's.
For bath oils, you could try one of Living Nature's body oils. These can be used for moisturising or massage, but can be also added to a bath. They have Body Form Oil, Energy Body Oil, and Tranquility Body Oil, all $23 for 100ml.
If you're after a moisturising bath treatment in solid form, you could try one of Lush's Luxury Bath Melts, like Ceridwen's Cauldron, $10.90.
