Square Modular Floating Island Models

This easy-to-plant square floating island can be customized for your floating habitat solution, or pond restoration project. BioHaven® modular floating islands for habitat & water quality are the perfect bio-remediation tool for ponds.  If you are looking for the best modular island floating solution, we can help.

The BioHaven® brand is a leader in Floating Treatment Wetland Technology, with over 5,000 islands launched worldwide.  Each BioHaven floating island is made using 100% RECYCLED PET Plastic, BioHaven floating island is the perfect biological solution for a healthy pond.  Studies have shown positive results to water quality where BioHaven floating islands have been used.  Our islands are handmade in California and are meant to last.  If you are looking for a natural solution for a healthy pond, go with a trusted brand – BioHaven floating islands clear water naturally by removing excess nutrients.

Create a lush floating garden while providing habitat above and below the waterline.  BioHaven® floating treatment wetlands act as living biofilters that promote microbial activity.  Like natural wetlands, which offer both surface area and circulation, BioHavens offer “augmented surface area.” The Matrix serves as a housing unit for all of these microbes…they live in the matrix and feed off of many of the nutrients in the water. Biodiversity at its best!

About the floating island standard square models

While we can custom create any shape or size, we offer 3 standard square models for clients looking to start small and add on as time allows.  Our modular floating islands make it easy to transport and launch. These modular floating islands are readily available in the following 3 sizes.

3 x 3 foot (approximately 9 square ft)

4 x 4 foot (approximately 16 square ft)

5 x 5 foot (approximately 25 square ft) 

*Don’t see what you are looking for?  At Floating Islands West, we are able to customize just about any shape or size for the perfect floating island.  Just let us know.

Each of our floating island models are manufactured with individual planting pockets and can be planted with your choice of aquatic or terrestrial plants.  If you are searching for a nesting island for ducks, or even a swan habitat island, these floating islands will allow you the flexibility that you need.  The square or modular island design allows you to buy now and add on later, creating a bigger island as time and budget allow.


From the moment your BioHaven® is placed into the water, even prior to adding plants, our bio matrix (proprietary design) kick starts the water treatment process through microbial activity.  This is not your regular swan nesting island, or a simple basking platform for a pond turtle, we offer a genuine floating treatment island backed by years of research.  We recognize the need for clean & clear pond water; by using the islands in our own pond, we enjoy zero pond odor while keeping the pond water clear, the natural way.  A healthy pond = a happy ecosystem & BioHaven floating islands are the perfect pond product to control algae, while providing shade and cover for your fish.


Remember, we can customize any island to meet the needs of your pond or lake.  Let us know what you want.
