Yes it does, I wasn't sure at first so I looked it up on the Homedepot app. It says instalation hardware is included.
It depends what kind of toilet you have. You either have a round toilet or oblong. If your toilet is oblong than this one does not fit into it.
I have NO IDEA what you are talking about! All I know is that I had NO problems installing this seat on my STANDARD Size toilet!
Product specs says seat length is 17.5, product depth 16.65 and width 14.57 It's a standard round (verses oval) seat and fits perfectly on my existing commode. Screws line up, seat is flush with bowl. No problems.
No. It is a medium to dark oak.
Absolutely not. The wood came apart within a week of installation.
