Drawer depth for base cabinet for sink

I am still planning my new kitchen. You have already helped me here many times and I would like to thank you in advance for your further answers. If I take a sink cabinet with drawers, how deep are the drawers then? I have the supply and drain pipes for the sink water and the dishwasher under the sink. Since the nearest Ikea is 180 km away, dropping by quickly to have a look is not really convenient, so I am hoping for your answer. Anita

The bottom one is 45 deep, the tall Maximera (suitable for the waste systems), the one above is only 37 deep and low or medium.
