I spent my Saturday afternoon re-caulking my bathtub & shower. It took several hours because I had to scrape off the old caulk & scrub the tub/shower before I could put in the new caulk. I'm rather proud f how it turned out, mainly because it was the first time I've ever caulked anything. It could look better. I could have used tape to get nice straight lines, but I think I did a decent job of it.
