Floor Conversion System for Swimming Pools

Floor conversion system for swimming pools to expand their potential for multipurpose use

Forefront floor conversion system for swimming pools

Our floor conversion system for swimming pools can freely convert an official competition swimming pool into an arena and ice skating rink by moving the floor vertically with a hydraulic cylinder. This breakthrough system expands the range of swimming pool uses and offers more opportunities for all generations to enjoy.

Examples of other uses for a swimming pool

In addition to adjusting the water depth, the multipurpose pool system can lift the floor to the uppermost level to convert the pool into an arena.
