A Natural Full-Sand Swimming Lagoon, Explained
A full-sand lagoon is a private freshwater beach: a 100% sand basin you enter on a gentle slope, with no steps, no ladders, and no concrete underfoot. The sand is not a decorative layer over concrete, it is the actual floor of the basin, and the water stays clear through freshwater UV disinfection and a closed-loop filtration system, with no chemicals added. It is not a pool, and it is not a pond. It is a real freshwater beach, built on your own property by CLAIR LAGON®.
Three Models, Scaled to Your Land
Our lagoons come in three sizes, from an intimate garden cove to a generous space built for gathering. Find the one that fits your property and how you want to live around the water.

Anse
The intimate scale. A private cove tucked into your garden, sized for a family who wants their own quiet stretch of water.
From roughly 30 m²+
Note the Anse on my consultation
Crique
The mid scale. Room enough for family and friends to gather around the water, with a longer shoreline to design against.
From roughly 80 m²+

What It Feels Like to Own One
Warm sand shifts underfoot as you wade in. There is no ledge to find with your foot, no chemical sting in your eyes, just clear freshwater and a slope that lets you walk in at your own pace, the way a real beach does.
The safest way for a child to enter water
There are no steps and no ladders. Your lagoon opens with a gentle beach slope, so a young child wades in the way they would at a real beach, with no ledge and no sudden drop underfoot.
Real fine sand underfoot
This is a 100% sand basin, not a concrete floor with sand dressed on top. Every step you take across the bottom of your lagoon is on real, fine sand.
Freshwater your kids can swim in all day
No chlorine, no red eyes, no chemical smell on your skin or your swimsuit. The water is kept clear by UV disinfection and a closed loop, not by additives.
Less to keep up than a chlorinated pool
Without chemical dosing to manage, your lagoon asks less of you week to week than a traditional pool. See how the upkeep works on our How It’s Built page.
How It Stays Clear, Without Chemicals
Freshwater moves through a closed loop and past a UV disinfection stage, so your 100% sand basin stays clear without chemicals and asks less of you than a chlorinated pool.
Make It Yours
You choose the sand tone, the rock, and how the planting frames the water. The lagoon is yours, down to the shoreline.

Choose the tone of your beach, from pale and bright to warm and golden, so the shoreline reads the way you want it to against your home.

Natural rock sets the character of your cove, from soft boulders tucked into the planting to a bolder Mediterranean edge along the water.

The planting around your lagoon can be lush and garden-fed, dry and Mediterranean, or kept minimal and quiet. You decide how the water is framed.
Not a Pool. Not a Pond.
Not a pool with sand added
A concrete pool with a sand ledge is still a concrete pool. Your lagoon is a 100% fine-sand basin with no concrete floor underneath it, from the shoreline to the deepest point.
Not a pond that needs garden upkeep
A planted pond relies on its own ecosystem to stay balanced. Your lagoon is freshwater, kept clear by UV disinfection and a closed-loop system, so it swims clean without that upkeep.
What it actually is: a 100% fine-sand basin you walk into on a gentle beach slope, kept clear by UV disinfection and a closed loop, a real freshwater beach on your own property.
