What a Clair Lagon Costs, and What Your Property Needs

A Clair Lagon fine-sand lagoon starts at $150,000, as a custom-built, luxury installation rather than a fixed pool package. Your final number depends on the model you choose, your site conditions, and the level of customization you want, all of which we work through together in your consultation.

You will want at least half an acre. The smallest build is 5,000 sq ft total, made up of 3,000 sq ft of swim area plus 2,000 sq ft for the beach and filtration zone. There is no stated maximum: your lagoon's size is set by your land, not by a cap on our end.

No. Upkeep is a weekly filter rinse using reusable filters, and we provide two sets so one is always ready to go back in. That is less hands-on work than a chlorinated pool's ongoing chemical balancing and algae treatment. See /how-it-works for the full picture of how we built it that way.

It is not a chlorinated, lagoon-style concrete pool with a sand ledge along one edge. A Clair Lagon has no concrete floor at all: it is a 100% fine-sand basin from edge to edge. It is also not a plant-zone natural pool or pond that needs ongoing garden upkeep to stay clear. Ours runs on freshwater with UV disinfection, with zero plant zones to manage. See /our-lagoons for the full picture.

Most builds run 3 to 12 weeks from groundbreaking to your first swim, and in as little as 3 weeks for the fastest builds. Timeline depends on your model and site conditions. See /how-it-works for the full 8-step build process.

There are no chemicals. The water is freshwater, kept clear with UV disinfection and zero additives. The beach-entry slope has no steps and no ladders, so a child wades in gradually just as they would on a real beach, which makes it one of the gentlest, safest entry geometries you can build into a home water feature.
