Totally LOL@Butthead!!!
Lowman, don't forget rewiring for the recessed lighting and new fart fan...
The new entry door and/or hardware...
The toilet could be updated...does it match the sink?
How 'bout a new toilet paper holder and towel racks???
Oh, and speaking of sink...new vanity and faucets...
Floorboards...
Drywall texture...
Paint and caulking...
Shower curtain vs enclosed or sliding glass doors...hmmm...
Flooring? Manmade vs natural...
Labor, sweat equity, dust, insanity, fights, dust, money, dust...did I mention dust?
You are in for it!
