Scott,

Most have a plastic cap that nicely covers the bolt and washer. To me
that looks nicer than a bolt head and washer, stainless or otherwise. YMMV

I would just replace the nuts and washers with stainless steel, but the
toilet rocks, so presumably at least the one that fell into the hole
needs a new washer and nut. I figure as long as I'm buying parts I can
get enough for both sides so that they both look nice.

Can I even get toilet bolts in stainless steel or will I have to use
regular stainless steel bolt if I replace the bolts. I know toilet
bolts look different...
