Tub liners

INSTA-BLOC PU rigid foam tub liners are connected directly to the shower base or bathtub at the factory and are suited to all popular brands and models. INSTA-BLOC tub liners are functional, sophisticated, and due to their minimal weight they are also easy to transport and install. INSTA-BLOC tub liners have outstanding heat and sound insulation characteristics.


Accessories such as adapters for niche filling pieces, borders or steps for bathtubs are available. 

In order to make installation easier, all tub liners are manufactured with a prefabricated installation slot for bath sets, tillers and overflow fittings – cutting bits out on site is no longer required. 

Recesses for connection cables and inspection openings can easily be installed.
