I recently purchased the Grovia ONE all-in-one diaper to use on my toddler for nighttime. I was on the hunt for a new nighttime option because my son had outgrown his fitted, and we were just stuffing lots of inserts into his pockets for nighttime. It works well enough, but I knew we needed to find a reliable solution.

I had heard about the Grovia ONE diaper on Facebook. So many people recommended it for a nighttime diaper. I looked it up, felt the price was reasonable and gave it a whirl.

I created a video showcasing the different parts of the diaper. Hope you find it helpful!

Grovia ONE Diaper Video Review

Video Synopsis

The Grovia ONE is an all-in-one diaper that is extra absorbent for heavy-wetters or nighttime. ONE is an acronym that stands for the following:

O: Outlast closure

The Grovia ONE has a removable hook and loop option that can snap onto the snaps if you prefer velcro closures. If you prefer snaps, you can remove the line of hook & loop. Both the velcro and snap closure are extremely durable. You can see in the video how the velcro can be added and removed.

N: No Prep

This is an all-in-one diaper, which means nothing to stuff, wrap, fold, etc. The only thing you might have to do is snap the insert in, but it’s just one or two snaps depending on how many soakers you use. That’s it!

E: Easy to Use

This diaper is very easy to use. Once you see how the inserts attach to the shell (by snap), you’re good to go. It is a pretty typical all-in-one style diaper as far as putting it on your baby goes.

Diaper Materials

grovia-ONE-diaperAs I already mentioned, this diaper comes with snap closures with the option to convert it to hook & loop.

The outer waterproof layer of this diaper is made from TPU (thermoplastic polyurethane). This is an alternative to PUL (polyurethane laminate). TPU (and PUL) is the thin outer material on modern cloth diapers/covers. The difference between the two materials is in how they are bonded to the fabric–PUL is chemically bonded, and TPU is heat bonded. TPU might be more sensitive to heat in the dryer, so make sure you dry on low.

The soft inner layer of the diaper is made from polyester microfleece. There is a hidden layer of microfiber underneath the microfleece, but the main absorbency comes from the soakers. The soakers are 100{9994046f29331ee04cc0b5e07eb28364315ea03ccc2f01b5a43e8b85b372d1e9} cotton (with a top layer of microfleece for stay-dry protection). The diaper comes with two of them; one small soaker for smaller babies, and a large soaker for older babies. For toddlers, the two soakers can be snapped together and then snapped as a pair into the diaper. The snaps on the soakers are awesome for keeping them in place.

How Well Do They Work?

We have no had a single leak with this diaper! It has been a great fit for us. I will say, though, that it is not as absorbent as a high-end fitted.

I would choose the Grovia ONE over a high-quality fitted (such as Sustainablebabyish) if the following applies to you:

  • Moderate/Moderately Heavy Wetter
  • One-size is important to you
  • You prefer an all-in-one style

I would choose a good fitted diaper over Grovia ONE if:

  • Very heavy wetter
  • You want a trimmer fit

Update 12/13/18: We have now had a few nights where he out-wet them. As I was troubleshooting, I decided to try the velcro closure (we were using just the snaps prior). The velcro made a big difference! It allowed us to get a more precise fit, which trapped liquid better. If you have leaks with this diaper, I recommend trying the velcro if you aren’t already and seeing if that helps.

How Is The Fit?

grovia-one-diaperMy son is older now, so I don’t have many issues with leg gaps anymore. But it was a pretty flexible fit that should fit most babies over 12 pounds without much issue.

My husband commented on how much he loves the snaps on this diaper. They snap very quickly without too much effort, and they are very secure. He said this all on his own without me trying to pry an opinion out of him, so they must be some great snaps! 😉 This diaper was certainly made with quality.

When both of the soaker pads are snapped into the ONE, it is not all that trim. This does not bother me in the slightest, and it’s not so fluffy that it would be uncomfortable for the baby. It’s just fluffier than what you are probably using for the daytime. If you like to use zip up footie PJs, you might notice the fluffiness while trying to zip (at least, that’s when I notice!) If trimness is important to you, I would go the fitted route.

I do want to stress that it’s not a ridiculous amount of fluff, though. You can see in this pic what it looks like on my 18-month-old.


(Note: Prices can change at any time)

I paid about $23 for this diaper. I think that’s a fabulous price for an overnight diaper given the following:

  • All-in-One design–this is a very standard price for an all-in-one
  • High level of absorbency (more than your average all-in-one!)
  • One-size (Can use from the first couple months through potty training)
  • Made with quality

While this may be more than some people want to spend on one diaper, it is a fairly standard price. It’s important that you understand the difference between companies that produce diapers cheaply and companies that operate under more ethical standards. It’s not an apples to apple comparison to compare Grovia to a brand like Alva.

If your primary purpose for purchasing this diaper is to use it for overnights, you can get by with just a few of them. That will save you some money while giving you a good quality overnight diaper.

Would I Buy It Again?

Yes I would, and I plan to! I’m not sure what all the sales are yet, but Grovia usually does great sales periodically! Even at full price, this diaper is worth trying out.
