Remove the questionable tiles from the wall. Scrape out any loose grout, broken tiles or other foreign objects with your putty knife. You may need a grout scraper on some parts..
Make sure the area is dry before continuing. If it's damp, avoid using the bathtub for a few days beforehand. Use a hair dryer on the area to help expedite the drying process.
Apply tile adhesive to the back of the tiles. Position them in place, and hold firmly for sixty seconds. Make sure all the tiles are properly seated.
Grout around the tiles. Use a pre-mix type for ease, which is available at virtually any hardware store. Make sure all cracks are filled using a putty knife to press the grout deep into the cracks. Once the grout is in place, wipe the excess with a damp sponge and smooth down the grout lines.
Allow 48 hours for the grout to dry thoroughly before using the bath or the shower.
