Well it's been about a month since I updated this thread. A lot has changed since then, mainly that now I am a proud father of a little boy! Here's a quick pic of how my life changed dramatically:

Anyways, that definitely slowed me down on my fast paced tub remodel, but I think it is coming to an end now. I finished grouting tonight, so the only thing left is caulking, sealing, and painting the drywall on the outside edge of the tub. Here's the pics:

So far I am really happy with the job, but I fear the caulking part. The outside trim is some type of travertine chair railing from Lowe's as well. Gives it a sort of ancient greek look. I just need to decide on what to use to seal the grout and travertine now, any suggestions???
