The Verdict
Most bath color tablets are either overpriced for what they deliver or so packed with synthetic dyes and fragrance that they defeat the purpose of a relaxing soak. The Tub Works Bath Color Fizzies sit in a sweeter spot: 150 nontoxic, fragrance-free fizzies that turn your tub into a kaleidoscope without turning your skin into a science experiment. At a 4.4-star average across 220 ratings, they’ve clearly earned their keep — but they’re not for everyone.
What you actually get
The 8-ounce jar (roughly 5.5 inches tall) arrives packed with 150 individually wrapped fizzies. Each one is about the size of a large marble — enough to tint a standard tub a soft pastel, or drop in three or four for a deep, saturated color. The packaging is straightforward and child-resistant, which matters if you’ve got curious little hands around. No scoop, no mess, no measuring.
How they perform in the real world
Drop a fizzy in running warm water and it immediately starts effervescing — full dissolve takes about 2-3 minutes. Color payoff is genuinely impressive. The reds are cherry-bright, the blues are ocean-deep, and the purples actually read as purple rather than grayish-mauve. I tested them in a white acrylic tub and let the water sit for 20 minutes after draining: zero staining on the tub surface, and no lingering tint on skin. That’s the critical test for any bath colorant, and these pass cleanly.
The formula is simple — sodium bicarbonate, citric acid, and a nontoxic colorant. No fragrance, no essential oils, no moisturizers. That’s a double-edged sword. On one hand, it means you can layer these under your own bath oils or bubble bath without competing scents. On the other, if you’re expecting a moisturizing soak, you’ll be disappointed. These are purely visual fun.
What buyers consistently say
The overwhelming sentiment in the reviews is that these deliver exactly what’s promised. One reviewer wrote, “My kids beg for bath time now. The colors are so vibrant and they don’t stain the tub at all.” Another long-term user noted, “I’ve bought these three times now. They last forever — a single fizzy is plenty for a nice pastel color, and my sensitive skin has never reacted.” The durability of the 150-count jar is a recurring theme; most buyers report months of use before running out.
Where they fall short
The lack of any skin-conditioning ingredients is the biggest gap. If you’re used to bath bombs from Lush or similar brands that leave your skin soft and lightly scented, these will feel bare-bones. Also, the fizz is short-lived. One fizzy colors the water but stops fizzing within a couple minutes. For a longer soak, you’re either dropping in more or accepting the color as a static backdrop. A few reviewers also mentioned the jar lid can be stubborn to open initially — a minor gripe but worth noting if you have arthritis or grip issues.
Who should buy these
- Parents of young kids: The fragrance-free, nontoxic formula is ideal for children’s baths, and the visual appeal turns a chore into an event.
- Sensitive-skin bathers: If you love colored bath water but react to essential oils or synthetic fragrances, these are a safe bet.
- Cost-conscious color lovers: At roughly 150 uses per container, the per-bath cost is pennies compared to single-use bath bombs.
Skip these if you want a moisturizing, aromatherapy-style soak. These are color toys, not spa treatments.
FAQ
Will these stain my bathtub? No — in our tests and across dozens of reviews, the color rinses away cleanly from acrylic, porcelain, and fiberglass tubs. Just drain promptly and wipe down as you normally would.
How many fizzies should I use per bath? One gives a light pastel tint. Two to three produce a vivid, Instagram-worthy color. Four or more will make the water deeply saturated — arguably too dark for some tastes.
Are they safe for kids? Yes. The ingredients are food-grade and nontoxic. They’re fragrance-free, so no respiratory irritation concerns. Just supervise toddlers so they don’t eat them — they’re not candy.
The Verdict
Buy it if you want affordable, fragrance-free bath color that actually delivers vibrant hues without staining — especially for kids or sensitive skin.
Skip it if you’re seeking a moisturizing, scented spa experience; these are purely about color and fizz.
Rating: 4.2/5 — Great value, honest performance, and zero gimmicks. Just don’t expect skin benefits beyond the fun.
