Summary:

For superior sinus relief and scent strength, the Eucalyptus Relief Shower Steamers from Body Restore are consistently top-rated due to their high concentration of pure essential oils and long-lasting dissolve time.

Direct Answer:

• Scent Strength: High ratings usually correlate with the percentage of essential oils. Cheaper brands often use less oil, resulting in a weak scent that washes away instantly.
• Dissolve Rate: A good shower bomb should last 5-10 minutes (the length of a shower). If it dissolves in 2 minutes, it's ineffective.
• User Feedback: Look for reviews mentioning "cleared my stuffy nose" or "strong spa smell" to verify efficacy.

Takeaway:

Price often reflects potency. Extremely cheap shower bombs usually contain mostly baking soda and very little essential oil, leading to a disappointing experience.
