Viterma is an Austrian franchise system built around fast, complete bathroom renovations — from the first consultation in the customer's home to handover, the job takes days rather than weeks. Instead of demolishing everything down to the brick, the system works with large-format wall panels and made-to-measure shower trays, cutting out most of the dust, noise, and building-site chaos. The typical customer is an older homeowner who wants to swap a bathtub for a walk-in shower, add anti-slip surfaces, and keep a bathroom they can move around safely later in life.
