Swimming ponds
A swimming pond is the wilder relation of the natural pool: a lined pond with sloping, planted edges and a deep, open area for swimming in the middle or at one end. Where a natural pool often has a defined swimming box and a separate plant zone, a swimming pond blends the two, and is designed to look as if it has always been part of the land.
Because ponds are usually larger and less built-up, the price per square foot tends toward the lower half of the $50 to $100 national range, though big earthworks and stone edges push it up. A 1,000 sq ft pond is commonly $50,000 to $100,000.
A swimming pond makes sense if
- You have a large yard or acreage and want water to be a landscape feature.
- You like the idea of wildlife, from frogs to dragonflies, sharing the water.
- The ground slopes or has a natural low point that suits a pond.
- You care more about a cool swim than about laps in a straight line.
- You want the lowest-equipment option of all the natural systems.

Earthmoving on clay or rock, and long runs of natural stone, add the most. The cost guide shows a range for your size.
Design points that matter
Depth
A swimming area of at least 6 to 7 ft keeps water cooler at the bottom and gives room to swim. Shallow water warms fast and grows algae.
Gentle edges
Shelves step down from the bank so plants sit at the right depth and swimmers have a clear way in and out, usually by a deck, steps or a ladder.
Liner and protection
A rubber liner with fleece under and over it, often with gravel on the shelves. Exposed liner degrades in sunlight.
Gentle circulation
A skimmer and a small pump keep water moving, or in some designs a stream or waterfall that doubles as a feature.
Keeping runoff out
The edge is raised slightly so lawn fertilizer and soil do not wash in after rain. Runoff is the commonest cause of green ponds.
Safety
A pond deep enough to swim in counts as a pool under most local codes, so plan where the barrier and gates go from the start.

Survey the ground
Levels, soil and drainage are checked, and the pond is placed away from runoff and overhanging trees.
Earthworks
The basin is dug and shaped, shelves are formed, and spoil is often reused to shape banks.
Line and plant
Fleece, liner and gravel go in, then the plants, ideally in late spring.
Fill and wait
The pond is filled slowly. Most look their best from the second summer.
Common questions
How deep should a swimming pond be?
Most designers make the swimming area at least 6 ft deep, often 7 or 8, with planted shelves of 6 to 18 in around it. Depth keeps water cool and gives algae less light at the bottom.
Do I need permission for a swimming pond?
Usually a building permit, and a barrier. Codes based on the ISPSC treat water over 24 in deep as a pool. Grading permits, wetland rules or setbacks from wells and septic fields can also apply; your county will tell you.
Will fish live in it?
Builders generally advise against fish in a swimming pond. They add nutrients, stir up sediment and eat the creatures that keep the pond balanced.
Can a swimming pond freeze?
Yes, and that is fine. It stays full through winter; the pump is usually turned down or off and plants are cut back in fall.
Is a swimming pond cheaper than a natural pool?
Per square foot often yes, because there are fewer walls and less hard finish. But ponds are usually bigger, so totals are similar.

We are an introduction service, not a natural pool builder. You hear the builder's name from us first; we hold your details back until you say they can go.
Thank you. We have your details.
- By the next working day you should hear from us, by phone or email, with a natural pool builder who builds near you.
- If you are happy with that builder, say so and we pass your notes on. If not, nothing is shared.
- The builder visits the yard and prices the design with you. We will not send you newsletters or offers.
