  1. Peter Stocks

    This water butt is just what I’ve been looking for. Fits neatly against the house wall, and holds a good amount of water. Very pleased.

  2. Julie M

    Quick delivery, excellent quality water butt at a great price.

  3. Amanda Shepherd

    Very stylish looking water butt, looks great at the side of our bungalow. Bought this water butt as it doesn’t stick out like traditional water butts. Item arrived promptly and was well packaged, no scratches or marks. Pleasant delivery driver too. Easy to install. Very pleased, just waiting for some rain now

  4. Ken Pearce

    Excellent service and product. Upgraded to a brass tap and pleased with how it looks. Needed a water butt that would not take up a lot of space and it fits the bill perfectly.

    • Garden Tech

      Thank you for your kind words Ken. We’re thrilled that you are happy with the Slim Stone Tank 🙂

  5. anthonylevett

    The water butt arrived promptly and we are very pleased with it. It fits very nicely alongside the house and down pipe, taking much less space than the old original butt. All in all a great product at a good price and looks good in the garden, combined with good service what more can you ask for?

    • Garden Tech

      Your review made our day! We’re grateful for your kind words and business. Enjoy your new water butt and garden this year Anthony 🙂

  6. Clive

    Looking forward to putting it in place!

    • Garden Tech

      We aim to please! Thanks for the 5-star review Paul.

  7. Allyson McLeod

    I needed a new slim line water butt to go by the garage. It arrived very quickly & well packaged. The delivery driver was exceptional and carried the water butt into the garage for me. I just need to find the time to empty the water from the old butt into an empty one so I can put this slimline one in its place.

    • Garden Tech

      It’s great to hear you’re satisfied with the Dark Grey Slim Stone Wall Tank. Thank you!

  8. Anthony wills

    Brilliant product does exactly what it is supposed to do neat and compact with very good capacity

    • Garden Tech

      We’re grateful for the feedback Anthony. Thanks for the review.

  9. Sarah

    I wanted a slim fitting stylish water butt for the front of my house and this is perfect! The delivery service was excellent and was fuss free. The water butt is lighter than you might expect so not that difficult to move around. I will be back for another one for my back garden…

  10. Mary ELLIS

    Arrived promptly, very well packaged. Thrilled as it fits perfectly on the path at the side of the house.
    Quality and price excellent.

  11. Nigel Blackburn

    Ordered online and from placing the order to actual arrival excellent service, with efficiency, and very speedy delivery. Quality German engineering, excellent instructions and real value for money. Very pleased with both the Water butt and diverter. I will be using Garden Tech again very soon as I need more water storage for our increasingly hot summers.

  12. Andrew

    The stone effect of the Garantia Water Butt looks even better in real-life. Delivery was swift and the van driver went the extra mile and brought the water butt on its pallet right up to my front door. Very easy to setup, just need some rain!

  13. Darren Butler

    Excellent service, delivered very quickly and efficiently, very pleased with the items ordered. Easy purchase and good communication from Garden Tech, would use again.

  14. Mike

    Replaced a small water butt as built a shed so had more rain dispersed. Also wanted a nice looking slim one and this is a fantastic find, and a great price. As others have said the flow of water from the tap is superb – Niagra like :-)……. My only question is how I find a suitable connector to fix a hose to the tap as it doesnt appear to be a standard uk hose adapter size.

  15. Russell Taylor

    The water butt is exactly what I wanted, tall with a small footprint. Ideal for the modern small garden. If only I had found this for my previous 6 butts.
    Unfortunately the tap does not work so I am going to have to contact you to upgrade the tap.

  16. Noel Fowler

    Great design – we wanted something that sat close to our property wall thus taking up little space on the path and this fitted the bill perfectly.

    • Garden Tech

      Thanks Noel – enjoy your garden space this year!

  17. Maureen B

    Really good quality, attractive butt. Perfect for the right space on a patio.

    • Garden Tech

      Thanks for your review Maureen. We hope you enjoy your water butt and garden this year. Thanks, Team Garden Tech

  18. Louise Davis

    Lovely looking water butt. Doesn’t look out of place on our decking.
    Didn’t come with the tap but customer service very quickly rectified the situation. Would highly recommend and will be returning for another one when our funds allow. Great service. Many thanks ?

    • Garden Tech

      Thanks Louise 🙂 We pride ourselves on our products and aftercare so I’m glad the support team rectified things quickly for you. Enjoy your garden!

  19. Alison

    So great to find a functional product that also enhances the look of our deck. It has received many positive comments from friends and family. It will be so easy to water the pots and planters this summer

    • Garden Tech

      Thanks for your review Alison 🙂 We’re so glad you are happy with your new water butt. Enjoy your garden this year!

  20. Tom

    Very good product. Easy to install. Does the job it was designed for and looks attractive. Water pressure when released is amazing. Quick, professional delivery, delivery guy couldn’t get his huge lorry into our Close, so had to park around the corner. He delivered the pallet by hand without any complaint. Very good process all round. Would recommended.

  21. Shaun Womersley

    The water butts are great and very well priced. Both arrived well packaged and the delivery driver was excellent. The only delay I had in fitting was not having a 1 inch cutter tool to fit the tube fitting from the gutter fall pipe but I would definitely order again.

  22. Jude

    Brilliant, the speed of which the water comes out is amazing, it looks really elegant (for a water butt). So easy to assemble and the thinner design will fit in so many places. I might even get another one for the back garden.

    • Garden Tech

      Thanks so much for the kind words 🙂 If you do order another water butt, we’ve set up a 5% off coupon code for use with your email address only. Just use “jude5off” as the coupon code when checking out.

      Best wishes,

  23. Julie

    Very pleased with these water butts (bought 2). Really good flow rate so very quickly fills up watering can. Just need rain now

    • Garden Tech

      Thanks for the kind words Julie. We hope you enjoy your garden this year!

  24. Debra Fox

    I am loving my new water butt. Can I just say I am over the moon with our new water butt which I bought for my garden. It fits perfectly in the space I hoped it would. Great service and over all very happy! Best wishes Debra

Can my water butt be attached to a wall?

Most water butts also known as water tanks are stable structures. Any water butts that, due to their particular shape, could fall down, we supply wall mounting brackets for added stability.

How do I prepare my water butt for winter?

Water butts can freeze if not drained for the winter, depending on their location and local weather conditions. If water freezes in your receptacle, the water butt may crack or deform under the pressure.

Do the water butts need added filtration devices?

All of Garden Tech’s water harvesting products are already equipped with a filtration device. Collected rainwater should only be used for gardening purposes and should not require any extra filtration.

How do the downpipe filters work?

When collecting rainwater, a downpipe will collect water from the roof via a drainpipe connected to your water butt. The downpipe filter works by combining a steel or plastic grid with the walls of the downpipe, to allow heavier bodies to fall through the centre of the pipe.

Can multiple water tanks be joined together?

Our range of water butts can be easily joined together if needed. This can be done with a simple connection kit that contains a small hose, a drill bit, and the fittings needed to connect the water butts together.

Shouldn’t the tap be at the bottom of the water butts?

No. This clever design feature ensures that the water butt always contains enough water to maintain its stability and avoid it getting blown over by the wind.
