Ask to view a previous installation. Remember, showroom kitchens have perfect walls and are not connected to electricity, gas or water. Quality equipment will ensure a long-lived kitchen. There is no substitute for knowledge when speaking to potential suppliers. Educate yourself on all aspects of your project before speaking with retailers or installers.     It is essential that you choose good quality when buying a new kitchen. Appliances are the engines on which a good kitchen will run. Neutral elements are the comfortable interior and worktops the tough exterior that provides longevity and resilience.     Equipments should have a solid base construction; it is recommended that metal sided drawers and runners with full extension be used. Shock absorbed drawers are the new standard bearer here.     To ensure a smooth kitchen installation, good preparation is vital. Planning of plumbing, gas, ventilation, air conditioning and electricity services should be carried our prior to the installation wherever possible. Is your supplier capable of doing it?     Ensure you choose an experienced technician/s and fitter/s who will show you their previous work. Make sure you request to see the stock of spare parts available with the supplier. Ask questions about the supplier/consultant from previous clients. Good designers or installers aren't unlike artists and they thrive on good feedback. Liaise with all those you employ regularly throughout the process. That way any misunderstandings or confusion can be rectified whilst work is in progress.     Client, designer, installer and supplier should work as a team aiming to reach a common goal - success and satisfaction.
