Loved by families with sensitive skin.
Real routines, real bathrooms and honest experiences with KindFlow.
Bath time feels much calmer
My son's skin used to look dry and red after his bath. Since changing the bath water, it feels noticeably calmer afterwards and we are not reaching for moisturiser quite as frantically.
So glad I found this
We had changed the wash, detergent and creams but never thought about the water. Her skin seems less itchy after bath time now and the whole routine feels gentler.
Less tight and dry afterwards
I bought KindFlow for my own sensitive skin. The biggest difference for me is how much less stripped and tight my skin feels when I get out of the bath.
Her hair feels softer too
I originally bought it for my daughter's dry skin, but I have also noticed her hair feels softer and much easier to brush after bath night instead of feeling so straw-like.
The refill plan makes sense
The three-month refill option suits us because we use the bath constantly. I like that I do not have to remember to reorder and the refill discount makes the ongoing cost feel reasonable.
A simple change that actually fits our routine
I was sceptical because we have tried a lot for dry, reactive skin. It took seconds to hang under the tap and has been one of the easiest changes we have made to bath time.
Easy to fit and the bath still fills quickly
I expected a filter to slow the tap right down, but the flow is still strong. It is simple enough that we use it every bath without thinking about it - and it has definitely helped the kids' skin.
Worth it for one less thing to worry about
For us it is less about adding another product and more about improving the water the kids are already sitting in. I am really pleased we found it.

Questions, answered
Everything to know before your first bath.
Clear answers about compatibility, cartridges, delivery and the 60-day guarantee.
Who is the KindFlow Bath Filter designed for?
KindFlow is designed for families dealing with sensitive, dry and eczema-prone skin. In our customer research, over 85% of families reported improvements in areas including post-bath dryness, redness and itchiness after changing their bath water with KindFlow.
How do I install it?
There is no plumbing or screw fitting. Loop the strap over the bath tap so KindFlow sits securely beneath the outlet, then run the water through it as you fill the bath.
Will it work with my bath tap?
KindFlow is designed to hang over the majority of standard UK household bath taps, with no plumbing or adapters required. Taps with a significant curve, unusual shape or insufficient space to support the loop may not be suitable.
What does the filter reduce?
The replaceable eight-layer cartridge filters the water as it leaves your tap and the bath fills. Its combination of filtration materials is designed to reduce chlorine, odours, sediment, selected dissolved metals and other common tap-water impurities before the water reaches your family’s skin. See the "How it Works" section for more detail.
How often should I replace the cartridge?
Choose the refill schedule that best matches your household. We recommend a three-month rhythm for heavier bath use and a four-month rhythm for lighter use.
Can I change or cancel my refill subscription?
Yes. You can change your refill timing, skip a delivery or cancel the subscription if your household's needs change.
Will KindFlow slow down my bath tap?
KindFlow is designed to maintain a strong, practical bath-filling flow. Water runs into the top of the filter and through the cartridge into the bath without needing a sealed connection.
What does the 60-day guarantee cover?
Try KindFlow at home. If it is not right for your family, contact us within 60 days and we will arrange the return under our money-back guarantee. See the returns policy for the full terms.
