This is what we call a moisture trap. To remedy this you need a good extractor. The best sort is one directly over the cooker which can extract externally. Next best is a condenser type extractor unit. These have a charcoal filter to extract the moisture.
Permanent ventilation is always necessary in a kitchen, especially where gas appliances are fitted.
Floors It is common for people to choose cushion floors in the kitchen, but remember that kitchens get well trodden and it is preferable to have tiled floors which are much more hard wearing, but they do tend to be very cold to walk on. A timber floor would give a hardwearing surface and be slightly warmer underfoot. This is something that people find very intimidating, but don t worry, it's much easier to remedy than you might imagine. This will usually be under the sink, under the stairs or somewhere near the front door. After turning this to off you can remove the washer from the tap.
