As per vaasthu, it is not advisable to have a pooja room in the kitchen.
Try to keep in the hall or some other room. i.e South side or NORTH WEST ROOM.If it is not possible,
If you really wanted to have in the kitchen due to space constrain, make a small wooden shelf for pooja and keep it on the west side wall of kitchen facing towards NORTH.
After performing the pooja in the morning or evening you close the shelf shutters.
