Costco’s New Rain Chain Turns Downpours Into a Stylish Garden Feature That Lets You Water Plants for Free
A simple garden upgrade that turns rainwater into a free, sustainable way to water your plants
I’ve been into rain chains for years now, and we’ve written about them on Homes & Gardens quite a bit because they sit in that nice middle ground between something practical and something that also genuinely improves how a garden feels when it rains.
They’ve been having a bit of a moment in outdoor design lately, but they’re actually far from new. Rain chains originate from ancient Japan, where they were used to guide and harvest rainwater, and you still see them used in traditional Japanese homes and gardens today.
I’ve got the Lotus Rain Chain from Amazon in my own garden, and one thing I’ve noticed over time is how useful it is from a practical point of view. The water doesn’t just disappear into drainage – it can be collected and directed into a water butt or container and reused for plants.
That feels especially relevant right now, with the hotter, drier spells we’ve been seeing across both the US and Europe, followed by sudden, heavy downpours. When the weather swings like that, being able to capture and reuse rainwater properly starts to feel less like a nice extra and more like a simple habit worth keeping.
Why Rain Chains Work So Well
Costco’s Copper Rain Chain works in the same way, replacing a standard downpipe with something that slows the water down and makes collection more practical. Instead of rain disappearing instantly, it’s guided cup by cup, which makes it easier to channel into watering systems or barrels. And because it’s copper, it also develops that softer, weathered finish over time that blends into the planting rather than sitting as something new and shiny against the house.
There’s also a quieter benefit you only really notice after a while. The sound of rain changes – it’s softer, more broken up, almost rhythmic, rather than the harsh rush you get from guttering. On heavier days, the sound is rather calming and mesmerizing, especially if you’re by a window or outside under cover.
‘Rain chains work because they help you make better use of something that’s often wasted,' says Rachel Bull, Head of Gardens at Homes & Gardens. 'They guide water in a way that makes it easier to collect and reuse for watering plants, which is a simple but meaningful step towards a more sustainable garden. And just as importantly, they change the sound of rain in the garden. Instead of a harsh rush, you get a softer, more layered noise that adds a sense of calm, especially during heavier weather.’
When it comes to placement, the best places for a rain chain are the ones where you can actually make the most of the water. Ideally, that means somewhere it can feed straight into a barrel or another collection point, so the rain isn’t just disappearing into drainage. They also work really well where runoff naturally moves into planting beds, especially gravel areas or established garden borders that can help soak it up rather than lose it.
What I like most is that you almost forget they're there. Then it starts raining, and suddenly they're quietly doing their thing – guiding water you can reuse in the garden and creating this lovely, gentle trickling sound in the background. It’s such a small detail, but it makes rainy days feel a bit more special.
Shop Alternative Rain Chains
Costco’s copper rain chain is one of those seasonal garden buys that tends to sell out quickly when it’s in stock, especially at this time of year when people are looking for easy outdoor upgrades. If you’re not already a member, a digital Costco membership gives you access to its rotating range of in-demand garden finds.
That said, you don’t need a membership to get the same look or effect. Amazon has plenty of rain chains that do the same job, helping you guide rainwater more gently while adding a more considered feel to heavy downpours.
I’ve rounded up a few good alternatives below that work well in simple, low-maintenance outdoor spaces.
I really like the design of this one – it feels like such a thoughtful take on something usually so functional. This Terrain-exclusive copper and brass rain chain, shaped like little forest mushrooms, turns a basic downspout into something far more decorative, with a soft, organic look that fits beautifully into a planted garden.
This metal hanging butterfly rain chain is such a pretty way to replace a standard downpipe. I really like the butterfly detail – it softens the flow of rain and turns it into something a bit more decorative and gentle to watch. Made from sturdy iron, it’s built for outdoor use, but it’s the movement and detailing that really make it stand out, especially when it’s running in the rain.
This lotus cup rain chain is a really elegant alternative to a traditional gutter. I like the way the repeated vintage-style cups catch and guide the rainwater as it moves down the chain – it gives the garden a softer, more considered feel when it rains. As the water trickles through, it creates a gentle visual rhythm and a subtle sound that suits a quiet outdoor space.
