Rank #5 in Best Bottle Sterilisers 2026: 10 Ranked, and the Numbers That Don't Add Up
Grownsy Electric Baby Bottle Steriliser and Dryer
Price and rating as shown on Amazon when we collected them. Both change.
The Grownsy Electric Baby Bottle Steriliser and Dryer is number 5 in this guide. It is a steam steriliser with a drying phase, sold with two stackable baskets that can be used on their own or together, and the listing puts the capacity at 5 standard bottles or 4 wide-neck bottles. The price is £59.99 and the listing carries a 4.4 rating from 4,019 ratings.
The numbers on this page are the ones worth looking at twice. The "8-minute" figure in the product name covers the sterilising stage only — steam sterilisation is one of five programmes, and the listing never states how long the sterilise + dry programme takes. The 99.9% bacteria figure is the highest claim in this guide, shared with Tommee Tippee, Philips Avent and Dr. Brown's, where Milton goes the other way and claims 99%. On the ratings, the listing shows 4,019 ratings and gives 23 July 2025 as the date first available: a large number of ratings in a short window, 78% of them at five stars and 7% at one star. Everything here comes from the Amazon listing for this model — we have not run the steriliser through a lab test, and the ratings quoted are the ones the listing displays.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I bought this steriliser in March of this year, and was very happy with it until it stopped working last week, just 3 months later. I contacted the seller, and they asked me to send a video and describe the problem, which I did. The seller got straight back to me, and within 2 days I had a replacement at my door, things can, and do go wrong, but customer service like that deserves 5 stars”

The listing says it holds up to 5 standard bottles or 4 wide-neck bottles, plus teats and smaller accessories, using the lower basket, the upper basket or both together.
Which bottles are compatible?
The listing names Tommee Tippee, Philips Avent and MAM as popular brands that fit, and says it also takes breast-pump parts, teats, dummies and teethers, suiting most standard and wide-neck bottles.

Five: Sterilise, Dry, Sterilise + Dry, Sterilise + Intensive Dry, and Hygienic Storage. The listing says a combination programme moves from sterilising to drying and storage without changing settings.
