About
Box-Welded Pond Liners Box-welded pond liners are custom-fabricated to your pond's exact dimensions, with factory-welded corners and seams that create a smooth, fold-free interior. This premium liner option is the top choice for formal koi ponds, raised pond builds, and any installation where a clean, wrinkle-free appearance matters. Play It Koi offers box-welded liners made to your specific measurements. Why Box-Welded? Standard flat-sheet liners create folds and pleats in rectangular or square ponds — these folds trap debris and are difficult to clean. A box-welded liner drops into the excavation like a fitted sheet, with smooth walls and floor. The factory welds are stronger than field seams and guaranteed leak-free. Pro tip: provide exact measurements including any shelf depths and drain locations. Box-welded liners are made to order and cannot be returned, so measure twice. Play It Koi offers free shipping on orders over $99. Questions? Contact our pond experts for a box-welded liner quote.
