How to Prepare for a Productive Visit

Before attending ISH Frankfurt, careful planning can significantly improve the value of your visit:

• Define your strategic priorities: Identify whether your focus is on bathroom solutions, water-bearing systems, installation technology, heat generation, indoor air, building management, software, or sanitary and HVAC production
• Prepare questions about system capability and operational performance: Define the building type, project stage, required output, available installation space and existing infrastructure before comparing systems. Ask suppliers about seasonal efficiency, part-load performance, noise, hydraulic or control integration, commissioning, maintenance access, spare-parts availability and lifecycle cost. For water systems, examine drinking-water hygiene, drainage, rainwater management and treatment. For indoor air, assess filtration, heat recovery, humidity control and cooling capacity
• Review the official event programme: Check for confirmed conferences, stages, guided tours, special areas and product demonstrations relevant to your visit
• Divide the exhibitor landscape by solution fields: Before the event, group exhibitors by the eight official solution fields — bathrooms, water-bearing systems, installation, heat generation, indoor air, building management, software, and production — to structure your visit efficiently. The fair takes place from 15 to 19 March 2027 at Messe Frankfurt
• Plan meetings with potential partners: The event provides an opportunity to coordinate with manufacturers, suppliers, and industry professionals in one location
