Ok, so I decided to clean the outside of the kitchen windows. They look great. Not so great, (in fact vomit material as I have been dry retching trying to deal with the situation) is that some water got into the inside track of one of the windows (the one that doesn't open). I didn't think anything of it figuring the water will evaporate. What I hadn't taken into account was the smell. There has been a faint smell and I couldn't work out what it was - until I discovered the water in the track. OMG does it stink. I have been trying to mop it up with kitchen towelling and nearly vomiting in the process. I have tried blow drying it - just spreads smell even worse. Any ideas as I am gagging? The smell is now spreading......

apart from heat issues (check with manufacturers for a definite answer ) i prefer to have the appliances separated for ease of access and to have a set down space nearby

I want to do the same to free up a ‘stretch’ of bench space, rather than having only small work areas in the corner and ends of our small L shape. I am talking stove top only as oven will be in a tower with microwave. That means the cupboard underneath can utilise the whole space, albeit with relatively small door (430mm). We would have to offset the range hood on the adjacent wall due to window position but have been advised the modern hoods are powerful enough to extract steam without necessarily being positioned absolutely over the hot plates.

If there is nothing wrong with the carcasses/inside of cupboards, then only replace the door fronts. You can contact a kitchen specialist, they can do everything for you. But if handy, you can remove benchtop, being careful with sink and plumbing, yourself. If you are not changing the set out of the kitchen, then it is a straight forward job. Just making sure you get the trades in the correct order. Get an electrician to disconnect appliances before removing benchtop and reconnect new appliances when ready. Get a plumber to disconnect water and reconnect sink and dishwasher when ready.
