As billl said, moisture should be addressed with proper ventilation (fan). If you do not have one already, plan to put one in. I don't have personal experience with IKEA cabinets, though I have a disassembled one in my basement waiting to be installed as a utility sink. I read very positive things about the quality:cost ratio. Personally, I generally prefer drawers rather than cabinets. Anything you can do to get extra drawers would be good. Unless the subfloor under the tub is damaged or you damage the tub while removing the flooring, there should be no reason you need to remove the tub. And even if you remove the tub, you could probably still reinstall it. I replaced my tub (it was harvest gold) and there had been a small amount of water damage. I pulled up the underlayment and the subfloor was in good shape. With water damage, you really don't know what to expect until you finish demolition.

Elizabeth, the floors have to go as they look better in photos. In person they scream cheap. It is cheap laminate. I will also have bare spots where the wall will be removed that I have to fix up. I was planning on putting some tile in the kitchen area but may just do hardwood throughout the whole house. I have also heard that the ikea cabinets hold up rather well but it seems that they use quite a bit of MDF with a foil over it. I personally would prefer a wood face as that sees quite a bit of abuse and potential liquid spills (I am just at the beginning with a 3 year old and 1.5 year old).

Great topic crl_ ! I spent a couple years figuring out what I wanted in my new kitchen. I had a pretty good kitchen before my reno, but there were definitely improvements to be made. My best changes: Drawers! Love lifting dinnerware up from drawer rather than down from upper cabinet. Love having my coffee cups in drawer immediately below coffee machine. Love not having to crawl around on the floor to access whatever is at the bottom and back of a cabinet. Induction! Probably the best surprise of my new kitchen, for all the same reasons listed above. Wall ovens! I don't know if I love my ovens because they are at the perfect height for me, or because I finally splurged on good equipment. Probably a combination of the two. I can tell you that my waist line is paying the price though! Big single sink. There's lots of discussion here about this. I grew up with double sinks, thought I'd probably get a low divide (best of both worlds, right?) but bit the bullet and got the single. It was, for me, the right decision.

With the possibility of multiple cooks in the house, and children who will also be learning to cook and help in the kitchen, I'd include a prep sink on the island. Helpers can load or unload the DW, or gather dishes to set the table, without crossing into the prep path. I increased the seating overhang to 15"--the minimum recommended by the NKBA.I, too, live in a multi-generational, multi-cook, household--my daughter, her husband, and their two children live with me. I love my second sink!
