The Caribbean underground lake is built in fiberglass and finished by hand with natural sands of marble and quartz, materials that give it a very natural color and excellent resistance to atmospheric agents, even the most extreme!
One of the features of this pond are the 2 internal steps designed for the positioning of marsh plants.
Once customized with the recommended optionals and inserted some nice goldfish you will have a wonderful pond that will give added value to your garden!
It is not necessary to create any connection to the water system, just place the basin in the ground.
