What are the best methods for filling the gap between a tub and tile to prevent water damage and maintain a clean appearance?

One effective method for filling the gap between a tub and tile to prevent water damage and maintain a clean appearance is to use silicone caulk. Silicone caulk is waterproof and flexible, making it ideal for sealing gaps in wet areas like bathrooms. Before applying the caulk, ensure the area is clean and dry to promote adhesion. Apply a bead of caulk along the gap, smoothing it out with a caulk tool or your finger for a neat finish. Regularly inspect and replace the caulk as needed to prevent water seepage and maintain a clean look.
