Why choose a box-welded pond liner?
Flat sheet liners have their place. But for any pond where finish and ease of installation matter, a custom-made box-welded pond liner is the professional choice.
Zero creases. Perfect finish.
A flat sheet always folds and pleats at corners. A box-welded pond liner is shaped to your pond — it lies flat against every surface with no excess material to tuck away.
Drops straight in. Done.
Installation is quick and clean. No wrestling with liner, no repositioning, no folds to manage. Unroll it, drop it in, and it sits exactly where it should.
Made to your drawing.
We produce a technical drawing of your liner before manufacture and send it for your approval. What you sign off is exactly what gets made.

Customer reviews
What our customers say
“We decided on a box weld liner — Jim advised us all the way. The liner fitted like a glove and looks so professional for our koi pond. If you are considering a conventional liner, stop — for the same price you can have a box weld which will look 100% more professional.”
David C.
Koi pond, box weld liner
“Two other companies made heavy weather of my request. Inspired Pond Liners understood what was needed very quickly, quoted sensibly and made the business very easy. I felt well supported with advice, and all the materials arrived very quickly. I can recommend without hesitation.”
Chris W.
Self-install project
“Even though the pond had problems — out of square, sloping sides and shelves — their team pulled it off and it fits. Will definitely use them again for future pond liner builds.”
