Underframe installation systems

    Ferroplast underframe installation systems are an ideal installation method for renovation and refurbishment. They offer considerable possibilities, especially where extremely little space is available under the bath or shower tray. 

    Used in conjunction with Poresta plinth panels the result is a ready to tile surface.
