I am referring to knobs on my doors. Cabinets are bronze downstairs and nickel upstairs. I don't want to have to change doorknobs to sell, which might be in a year or two. So, is it weird to do nickel upstairs and bronze down? Or is is better to do the whole house the same?

Hi, Kethy have something similar to the handles that they used. Only in black and brass though I believe https://www.kethy.com.au/product/l4370-brass Riley

I did a cavity door to my small bathroom. I reused the existing door and left the existing door handle. It was a beautiful door and that way stayed within the look of the rest of the house.

1. Go for it, prep is essential make sure everything is clean and holes ect have been filled in. Don't forget to number your doors so you know where they belong when you go to put them back. Use an undercoat. Don't skip steps. 2. Easily done and look for some online they can work out cheaper i.e facebook marketplace. If you keep the handle holes in existing cupboards make sure new ones fit or fill the holes before painting. 3. Don't paint it, that looks cheap and your going to touch it. They say "ready to use in 48 hours" No, no its not and its always dependant on the temp of your room. Replace it, should cost under $1000 for diy. If you want a trade add another $700 - $1800. They measure and order and cut and replace. It will take them less than an hour. It will take you maybe all day unless your pretty good already. 4. If you get a new benchtop (highly recommend) just get a new sink and make sure it will be suited for your sink cabinet. If you decide to keep the bench, you will have to get a sink in similar size. Make sure the tap sits over the sink and it is possible to do all this yourself. 5. Get stick on tiles as they can just sit on top and they aren't that thick. 6. Same with this, use stick on tiles for now. This is all quick fix and budget ways to update, how long it lasts is dependant on your use, your maintenance and the materials you use . i.e don't use cheap paint and follow after care instructions for all materials.
