Box welded liners for natural swimming pools
A natural swim pond deserves a liner that looks as good as the water above it. No creases, no folded corners — made to your exact specifications.
Why choose a box welded liner for your natural swimming pool?
No visible folds in the swimming zone
In a natural swimming pool, the liner is on display. Box welding eliminates the bunched corners and creased walls that detract from the appearance of the finished pool.
Large-format capability
Natural swimming pools tend to be large. We can manufacture liners to any size — there is no practical upper limit on the dimensions we can produce.
Regeneration zone integration
Many natural pools include a separate regeneration zone. We can manufacture the liner to accommodate this, including the separation wall and any steps between zones.
Shapes we manufacture
What to measure
For a natural swimming pool, provide:
- Overall length and width (m)
- Depth of swimming zone (m)
- Depth of regeneration zone if separate (m)
- Position of any steps or planting shelves
- Desired lip overhang (m)

Frequently asked questions
We recommend 1.0mm heavy-duty pond liner for natural swimming pools. The additional thickness provides greater resistance to UV exposure and the mechanical stress of regular swimmer contact.
