Use this calculator to work out the number of BlocX that you need for your double walled pond.
Just enter the Length, Width, Height and difference in height between the outer box and the inner box for the pond you
are looking for.
When you receive your BlocX you will also get detailed layer by layer instructions and we will cut the capping to the right sizes for you. Simple and fun!
All Prices include VAT but a delivery
charge will be added to your order.
Please enter Pond dimensions below.
As Large and Koi Pomds are normally larger
projects this calculator will give you a rough estimate of what your pond
will cost. We recommend that you get in touch with us at
as we are able to offer free design and discount on
larger and interesting projects.
