Custom shower layouts requiring trimming or shaping

How to use

Base Installation

Surface Requirements: Must be installed over a fully supported, structured floor
Steps:

Ensure substrate is level and clean
Fix the shower base using approved adhesive
Waterproof over the surface before tiling

Tip: Trim to fit with a handsaw or blade—works for circular or angled cuts too.

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.

Frequently Asked Questions

1. What is the fall on the CASA shower base?
Each base has a pre-formed slope of at least 2% to ensure water drains efficiently toward the outlet.

2. Can I cut the base to fit a custom shower layout?
Yes. The CASA base can be trimmed with a handsaw or utility blade to suit angled, curved, or tight spaces.

3. Is it suitable for use over timber floors?
Yes, as long as the timber floor is fully supported and structurally sound. Use an appropriate adhesive and follow waterproofing best practices.

4. What type of waterproofing should I use over it?
The base is compatible with most cementitious or sheet membrane waterproofing systems. Always check compatibility with your chosen system.

5. Can I use this in accessible or barrier-free showers?
Absolutely. The low-profile design makes it ideal for floor-level installs in accessible or step-free bathrooms.
