Good old father in law has the tools
I have a craftsman father and father in-law. I'm lucky like that. I get free advice, sometimes free help, and can borrow pretty much any tool I could need. Including a tractor and jacks for a house, hah!
Anyways, yeah I'm concerned about scratches and water dripping because my dog drinks half a bowl of water then walks around while it drips everywhere. I'm kind of resigning myself to the fact that I'll just have to do regular maintenance on them to keep them looking nice.
I know all about tools, I have so many tools that I'm seriously going to build a shed to hold more, because my garage is overloaded. I'm one of those guys that will buy every top name tool that comes out just in case I ever need it, because I've got a problem
Honestly, the tools for hardwood were tools I never knew existed, which is why I didn't have them. But you need a chainlink fence built, cut apart, redone? I have the tools for that. And I've never used any of them lol.
As far as the water concerns, you won't have to worry about water that's actually on the surface of the wood, because it's so heavily treated, sealed and glazed over that the water will never get through to the wood, and if it does it's harmless. The only thing that might make it dicey is the connection seams. But they sell wood putty type stuff to seal those, and it comes in every color and texture, so water is seriously not the concern you would think it could be. Unless you buy bargain basement laminate flooring, then it's screwed no matter what.
As far as the scratching goes, that's just unavoidable unless you go with a composite material, which costs significantly more. Some I saw were $20 per sq ft, and that's just crazy insane. If you haven't made your purchase yet, check out Lumber Liquidators: Hardwood Floors For Less!
they have crazy good deals, some to the point you wonder if it's stolen it's so cheap.
You want a really good deal? Tell 'em Large Marge sent ya
