*solid surface counter top that didn't need upkeep but didn't break the bank. I think I'd lean toward under-mount sinks, unless there's a drawback I'm not aware of. Simple stainless steel and porcelain. And probably a farm sink; the divided deal drives me nuts.
*toilets with reputations for efficiency and longevity (no crappy parts in the tank)
*smooth tile for wet/messy areas. I think I'd be tempted to go for that wood grain stuff, but things get stuck in grain.
*nice thick laminate everywhere else. OR real wood floors; like planks. With a really great finishing job.
*splurge on whoever I'm hiring to do it, so nothing is done sloppily.
*cabinets: honestly, at least in the kitchen, I'd probably stick with melamine. I like the idea of real wood, but water is monstrously bad for the finish. Unless you can get your guys to finish with spar varnish. But then it's a custom job and more $$.
ETA: the wood issue with cabinets is mainly under sinks, though, fwiw. If the finish job is good, it should hold up for a long time, but wood needs periodic refinishing, and if it's veneer and isn't kept in good condition, it can sustain irreversible water damage. All you can do then is paint or replace. Because that didn't happen to me, or anything. ;)
