I suppose the choice is up to you, but there are some issues that you should be aware of. First of all, you will have your steam oven door opening and closing all the time, so you need to be careful not to burn yourself when reaching into the oven. Secondly, if you need some access to the back of the oven and the fridge (such as to clean or replace the filters or light bulbs), you will need to move and remove both the oven and the fridge. If you decide to do it, you will also have to decide whether you want the refrigerator to be on the left or right, and you also need to remember to leave enough space for the doors to open. The design of your kitchen will be affected by the size of your kitchen, so you need to make sure that you leave enough space for the refrigerator. Good luck!
