Yes — the bathroom system used in Expandify homes is custom-designed and includes dedicated access space behind the plumbing.

While the walls are made from solid SIP (Structural Insulated Panel) systems, the bathroom fit-out is prefabricated with a design that allows for concealed plumbing and future access to pipework if needed.

This eliminates the need for traditional wall cavities while still allowing the required functionality and serviceability. All water-related walls comply with waterproofing and service access requirements.
