Bath by bath

Your first 30 days with Wavvy.

Every home's water and every baby's skin is unique. Here's what many parents notice as the days go on.

  1. Day 1

    The water feels softer and gentler from the very first pour.

  2. Day 7

    Skin feels less dry and more comfortable between baths.

  3. Day 30

    Bath time becomes a calm, dependable part of the evening routine.

Results vary based on local water quality, bath frequency, and skin sensitivity. WavvyBaby is not intended to treat or cure any medical skin condition.

For the whole family

Better for baby's skin — and yours.

You'll feel the difference too, because softer, cleaner-feeling water benefits the whole family.

Wavvy was made with your baby's skin in mind, but the benefits don't stop there. Parents tell us their own skin feels smoother and more hydrated after switching to filtered bath water.

Questions parents ask first

Frequently asked questions

What is the WavvyBaby Bathtub Filter?

The WavvyBaby Bathtub Filter is a soft silicone cover that slips over your bathtub spout and filters bath water through a triple-stage cartridge — Active Coconut Carbon, Calcium Sulfite, and Copper-Zinc media — helping reduce chlorine, heavy metals, and VOCs before the water reaches your baby’s skin. One cartridge lasts about 90 baths.

Will it fit my tub spout?

Yes — WavvyBaby slides onto most standard bathtub spouts. No tools, no plumbing. If your spout looks unusual, email a photo to hello@wavvybaby.com and we'll confirm the fit.

Does all the water go through the filter?

Every drop. Water can't reach the tub without passing through the triple-filter cartridge — no bypass, no gaps.

Will it slow down my bath?

No. WavvyBaby maintains full water flow, so the tub fills just as fast as it did before.

How long does one filter last?

One cartridge lasts about 90 baths — roughly three months for most families. With auto-delivery, a fresh $15 cartridge arrives right on schedule.

What if my baby has eczema or very sensitive skin?

WavvyBaby was designed for sensitive, eczema-prone skin — many parents notice calmer, more comfortable skin within the first week. It isn't a medical treatment, so for a diagnosed condition, check with your pediatrician.

Is it safe and pediatrician-approved?

Yes. WavvyBaby is pediatrician-approved, made from soft, BPA-free silicone with food-grade filter media.

How do I install and replace the filter?

Slide the silicone cover onto your spout — it takes seconds. When it's time to refill, swap the cartridge inside and keep the same cover.

What's your guarantee?

A 30-day guarantee. If you and your baby aren't feeling the difference, return it for a full refund — free return shipping included.

Is this for newborns or older babies too?

Both. WavvyBaby is gentle enough for a newborn's first bath and useful all the way through the toddler years.

How does the filter work?

Three stages: Active Coconut Carbon absorbs chlorine and odors, Calcium Sulfite removes up to 99% of chlorine, and Copper-Zinc media targets heavy metals. Every drop passes through all three.

Customers said this bathtub filter "stays centered" and reduces chlorine smell while maintaining normal water pressure. Many noted softer skin and "less drying" effects. "The silicone rinses clean" and provides faucet cushioning. Some found the fit loose on older spouts or noticed minimal difference. Installation takes "seconds" without tools.

A better fit than the hanging kind

The ball-style filter we tried kept sliding off and missing half the stream. WavvyBaby stays centered and all the water appears to go through it. Huge practical improvement.

Wish the refill came in the box

For a daily-use product, including one spare cartridge would have made the purchase feel more complete. Performance is good, and we have noticed less chlorine smell.

S
Shelly H.
No change in fill time

Our tub fills at the usual speed with normal pressure.

L
Lila D.
Gentler water on my hands

I notice less tightness on my own hands while washing the baby.

A
Alyssa C.
Helpful for our dry winter skin

Between the heat running and our city water, bath nights were leaving both kids ashy. Since adding this, their skin feels less irritated. It also covers the hard faucet nicely.

S
Sonya A.
Made bedtime baths easier

Once installed, it adds no extra step to our evening routine.

A
Alexis L.
Easy to clean after bubble baths

My toddler uses way too many bubbles, and I expected residue to build up. The silicone rinses clean under the faucet and the cartridge area drains quickly.

S
Sarah O.
Nice product, not a miracle cure

My son's eczema-prone skin is still eczema-prone, but it does not look as angry right after a bath. I like the filter and will keep using it alongside his normal skin routine.

E
Emma D.
Good filter, color was different

The filter itself works well and our bath water has much less of that pool smell. I ordered the blue shade and it reads more baby blue in person, so I took off one star.

C
Caroline S.
Nice results after a slow start

I did not notice anything the first few baths and almost returned it. Around week two, my baby's dry patches were less noticeable after bathing. Give it a little time.

G
Gabriela W.
Too loose on our old spout

It tilts under full flow, so we have to keep the pressure low.

S
Skylar V.
Pretty enough to leave on

The light grey color looks clean and does not scream baby gear.

E
Eliza B.
Stays put when grabbed

My toddler pulls on it, and it has not slipped once.

N
Nora R.
Helpful in the bath I supervise

I am a nanny and use this at my employer's home. It is easier than the hanging filter they had before, and the baby does not reach for the metal spout anymore.

N
Natalie S.
Clean-looking and easy to rinse

We have used it almost every night for three weeks. Soap splashes rinse off quickly, there is no musty smell, and the silicone still looks new. Very low maintenance.

K
Kaitlyn T.
Works as described

The packaging was neat, setup took less than two minutes, and the cover has not leaked. I am giving four stars because it is too early to judge long-term filter results.

L
Lily Q.
Soft cover saved one little forehead

My toddler stood up too fast and bumped the faucet yesterday. He was startled but not hurt because the silicone has real cushion. The filtration is why I bought it, but this mattered.

M
Melanie J.
Works in our rental

We cannot install a whole-house system in our apartment, so this is a good compromise. The chlorine smell is lower and there was no plumbing or landlord approval involved.

O
Owen E.
Softer stream

The filtered stream is gentler at low pressure. The build feels solid; I am undecided about keeping it.

D
Devon Q.
Works fine, instructions feel vague

The diagrams did not clearly show which side of the cartridge faces up. I guessed, then watched the online video to confirm. Once installed correctly, it worked as advertised.

C
Claire Y.
Our water feels less drying

After a week of daily baths, I noticed I was not immediately reaching for extra lotion on my baby's arms. The difference is modest but consistent, which feels believable to me.

M
Monica H.
Baby's skin does not feel stripped

We bathe every night because it helps our routine, but daily baths were drying. Since using this filter, her skin feels softer when I towel her off, even before lotion.

R
Raquel Z.
Soft cover is handy

The filter is the main win, but the padded spout helps too.

A
Autumn G.
Soft cover is a bonus

Bought it for filtering, but the padded faucet is handy too.

M
Madison G.
Helpful after moving to the city

Our new apartment water smelled much stronger than the well water we were used to. This toned down the odor and my baby's cheeks are not as dry after bath night.

P
Patricia V.
Bought one for each grandchild

I first purchased it for the baby with very dry skin, then ordered another for his cousin. Both parents say the water feels softer, and I like giving something they actually use.

N
Naomi G.
A calm newborn upgrade

Simple to use and reassuring for those first baths at home.

S
Simone B.
No slowdown at our faucet

The tub takes the same time to fill, which surprised me.

P
Paige R.
Still impressed

We have used it for roughly 25 baths. The silicone is not slimy, the filter stays seated, and my son's skin feels less rough. I rinse it once a week and let it air dry.

F
Felicia U.
Nice gift once I explained it

I gave this at a baby shower and the mom first thought it was only a faucet bumper. Once she saw the filter, she loved the idea. Better front-of-box explanation would help.

P
Priya K.
Finally fits our modern tub spout

We returned another filter because it tipped forward on our single-lever faucet. The WavvyBaby grips securely, handles full flow, and does not make the tub take forever to fill.

E
Erin U.
Works with our strong city pressure

I was prepared to turn the faucet down, but there was no need. The water runs through at normal pressure without overflowing, and the tub is ready just as quickly.

C
Camille R.
Thoughtful design for real life

It drains instead of holding a puddle, fits under the diverter, and has not shifted when my toddler grabs at it. Those little details are why I am happier with it than expected.

Ready when you are

Softer baths your baby will love.
