What to Look for When Buying CBD Bath Bombs Online

With so many CBD bath bombs floating around the internet, it’s easy to feel like you’re just picking your favorite scent and hoping for the best. Everyone promises “relaxation in a fizzy little ball,” but let’s be real - not all CBD bath bombs are created equal. And if you're not careful, that “soothing soak” might turn out to be nothing more than glitter soup with a side of disappointment.

Before you toss just any CBD bath bomb into your cart, here’s what you really need to look for, and why Tub Therapy is the one that gets it right.

1. Check the Type of CBD (It’s Not All the Same)

This one’s huge. A lot of CBD bath bombs on the market use something called CBD Isolate, sometimes labeled as “Pure CBD.” And while “pure” might sound impressive, it’s really just one single molecule - CBD on its own, with all the other helpful compounds stripped away. No terpenes. No minor cannabinoids. No hempy teamwork.

And when CBD flies solo? It doesn’t hit the same. You’re missing out on what’s known as the entourage effect - that magical synergy where CBD, THC (under 0.3%, totally legal), and other plant compounds work together to help your body truly relax, restore, and recover.

Here's an easier way to picture the difference: CBD isolate is grape juice. Full-spectrum is champagne. One’s fine. The other’s a celebration.

It’s giving entourage effect: Tub Therapy's Soakshow CBD Bath Bomb in Vanilla Rose is made with full-spectrum CBD, which means you’re soaking in the complete hemp experience - everything the plant has to offer, all working in harmony for a soak that actually delivers.

2. Check the Dose (100mg is the Sweet Spot)

Don’t be fooled by tiny 25mg bombs. If you’re trying to soak away stress, sore muscles, or the existential dread of having 97 tabs open, you’ll want at least 100mg of CBD to actually feel the difference.

But more doesn’t always mean better, either. Some bath bombs boast 300–400mg of CBD or more, but here’s the catch: it’s often pure CBD isolate. So while the number sounds impressive, you’re still missing the full entourage of plant compounds that help your body truly relax.

And with such a high dose of isolate, there’s often not much room left for the ingredients that make a bath bomb feel like self-care: Epsom salt, cocoa butter, or moisturizing oils. You end up with a bomb that’s all hype and no hug.

Goldilocks would pick this one: Tub Therapy's Soakshow CBD Bath Bomb in Milk & Chamomile hits the sweet spot with 100mg of full-spectrum CBD in every soak. That’s enough to deliver real results, especially when combined with skin-loving oils and muscle-soothing salts. Because it’s not just about the number, it’s about what works.

3. Read the Ingredients (Not Just the CBD)

Let’s zoom out for a second, because while CBD is the star of the show, it’s not doing all the work alone. A good bath bomb is a team effort, and the supporting cast matters a lot.

Most bath bombs start with the usual suspects: citric acid and baking soda. These are the fizz-makers, responsible for that satisfying sizzle when your bomb hits the water. Totally normal. But beyond that? You’ll want to take a closer look.

Keep an eye out for:

• Epsom salt is great for post-workout recovery, sore muscles, and giving your body that “ahhhh” feeling.
  

• Moisturizing butters like cocoa butter or shea butter melt into the water to deeply hydrate your skin.
  

• Plant-based oils – Think olive fruit oil, sunflower oil, or almond oil to lock in moisture without clogging pores.
  

And here’s the golden rule: if you can’t pronounce half the ingredient list, your skin probably doesn’t want to soak in it.

Good for you and plumbing: Tub Therapy's Soakshow CBD Bath Bomb in Jasmine & Charcoal is made with plant-based, skin-loving ingredients and zero parabens, sulfates, or phthalates. That means they’re safe for sensitive skin, septic systems, and anyone who just wants a little peace of mind while they marinate.

 

4. What About Color and Scent? (AKA The Addictive Part)

Let’s be honest: color and scent are what make bath bombs ridiculously addictive. The swirling hues, the dreamy scent cloud that hits the second you drop one in - that’s the magic. But that magic shouldn’t come at the cost of stained tubs or angry skin.  Because bath bombs should be relaxing, not a gamble between joy and a mess.

Here’s how to enjoy all the fun without the drama:

• Color’s totally okay, as long as it’s non-staining. Look for bath bombs made with Polysorbate 80, an emulsifier that helps oils and colorants mix evenly with water. Without it, those oils and dyes can cling to your tub (and your skin), leaving behind rings, streaks, or worse - you, looking like a tie-dye experiment. Polysorbate 80 solves that by breaking the oil into tiny particles that rinse clean. Science, but make it spa.

•  Scent-wise, skip anything that smells like a perfume counter exploded. Instead, choose bath bombs scented with essential oils or labeled phthalate-free. Why? Phthalates are synthetic chemicals often used to make fragrances last longer, but they’re known endocrine disruptors, meaning they can mess with your hormones. Not ideal for a chill soak.

Color, scent, zero side effects: At Tub Therapy, every Soakshow CBD bath bomb is crafted to give you the full sensory experience: rich, mood-boosting color (that won’t stain your tub), and light, clean scents that are either phthalate-free or from essential oils - never overpowering, always skin-friendly.

5. Look for Real Reviews (and Other Quality Indicators)

Gorgeous product shots? Great. But let’s be real: anyone can photograph a fizzy ball in a spotless bathtub and make it look like magic. If a product page is all polished imagery and zero real feedback, that’s a red flag. 

The real proof is in the post-soak glow... and what actual people have to say about it. You want to hear from people who’ve actually used the bath bomb - how it felt, how their skin reacted, whether the scent was too strong or just right. Because when regular soakers and bathologists agree, you know you’re not just getting hype. You’re getting results.

But don’t stop at reviews. Look for other forms of social proof too, like industry awards, press mentions, or expert recommendations. These third-party nods show that the product isn’t just popular - it’s been recognized for quality, performance, or innovation by people who know their stuff.

So before you hit “Add to Cart,” scroll past the pretty pictures and check for the receipts—real reviews, relevant recognition, and public praise that back up the claims. Because while beautiful photos are nice, proof and public love? That’s the soak-solid truth.

Best in soak: Award-winning CBD bath bombs, no less. Tub Therapy has been named Best CBD Bath Bomb not once, but twice - a nod to quality, care, and the kind of soak that actually delivers.

6. Check for COAs (Because Compliance ≠ Optional)

Here’s one a lot of people overlook: every legit CBD brand should have a COA - that’s a Certificate of Analysis, aka the lab report that proves what’s actually in the bath bomb you’re about to soak in. A COA means the brand has nothing to hide and everything to celebrate.

By law, CBD products must contain less than 0.3% THC, and the COA verifies that. If a brand can’t (or won’t) show this, run - because selling a product without proof of THC levels isn’t just sketchy, it’s non-compliant.

But beyond legal stuff, COAs can also show the good stuff:
✅ That your CBD is really full-spectrum (not mislabeled isolate)
✅ That it contains minor cannabinoids and terpenes
 ✅ That it’s been tested for heavy metals, pesticides, and solvents

Lab-tested, legal, and fully chill: Tub Therapy CBD bath bombs are third-party lab tested, so you’re soaking in true full-spectrum CBD with THC levels that are safe, legal, and worry-free.
