The order - The challenge

In various stages, and always outside the tourist season, all hotel rooms were renovated and all risers replaced. The new bathrooms were fitted with supply and drainage pipes and the sanitary appliances were also replaced. 


The biggest challenge was the time schedule. This was achieved by the teams from the heating, ventilation and sanitation trades, who worked together professionally and with enthusiasm and motivation. At times, ten technicians were working on the project for up to eleven hours a day.
