CASA Pre-made Shower Bases.

CASA boards are made of high-performance waterproof extruded polystyrene, it has a 1mm coating 
on either side comprising a glass fibre mesh embedded in a polymer-cement mortar. 

The shower base is a floor-level, barrier-free shower panel ready to receive a surface finish, pre-laid to fall at a minimum of 2%. Made of extruded polystyrene core or light solid polymer concrete, it is reinforced with a fibreglass mesh set into a polymer cement finish on each side, making it impact-resistant and compatible with most tile adhesives.

A structured floor must fully support the XPS shower base and is ideal for wet rooms and showers in confined locations. It can be easily cut to fit the shower area or to produce an irregular or circular shower base.
