As Niveko swimming pools are not restricted by shape, the possibilities to create a feature that is unique to your project and your requirements are endless. The Overflow Advance is a one piece swimming pool with a difference; a concrete ring beam, fixed with an overflow stone located in the waterline, ensures the water spreads over the surface, creating a mirror like effect. Furthermore, a slatted yet inconspicuous cover can be added to ensure a cost effective yet pleasing solution to protecting your swimming pool.
