Grout and caulk are two completely different substances, each with its own use and function. If you live in a home with an older bathroom, you may use one or both to make a repair or install a new bathtub, toilet or fixture.
Do you know when you should use grout or caulk around your tub? Grout is a mixture of water, cement, sand and sometimes fine gravel. This paste can be tinted different colors and is often used between tiles. Grout keeps water out and gives your walls and floors a cleaner look. Years of use can leave grout looking discolored and dirty. Caulk is strong enough and pliable enough to adhere two different types of materials, joints and corners to seal areas where air and water can leak. Homeowners can use caulk in several different ways, including around a bathtub.
You can use caulk to prevent water damage near drains, pipes, bathtubs or bathroom fixtures or for weatherproofing around doors and windows. One question homeowners often have is whether they can apply caulk over areas with grout. Caulk is usually applied around the perimeter of the bathtub where your tiles meet your tub. In those cases, you will likely apply some caulk in places where you also have grout. Over time, your caulk can shrink and dry out, at which point it loses its ability to create a strong seal.
When the material becomes compromised in this way, mold can get behind the caulk and start to grow. If left unchecked, mold can spread behind your walls or on your subfloor.
When this happens, you will have a much bigger problem than just removing caulk or grout. A sign that you should replace your caulk is when it starts to curl up at the corners or turn brown. You can also use clear silicone over existing grout to seal hairline cracks in corners. With practice, you can improve your technique and produce a consistent, clean line of caulk.

Is this a problem, and if so, what should you do about it? Many bathrooms are built with an intentional gap between the wall tiles and the bathtub. This expansion joint allows for natural shifting and movement which can occur in your home over time.
Most of these cracks can be sealed with caulk. Doing so will prevent moisture from accumulating, which can also protect against the growth of mold and mildew. To seal gaps up to a quarter-inch in width, apply sanded caulk that matches your grout. For large gaps, insert a backer rod first before you apply your caulk.
Make sure to purchase a rod which is nonporous and designed for use in wet areas. After you have pushed the backer rod into place, apply caulk on both sides of the rod to secure it in place. In some cases, you may need an L-shaped tub flange to fill in a gap between the wall and your bathtub. On top of this edge, you can install a tile or tub surround to hide the joint.
You can then apply caulk along the top of your flange to seal the surface and to give your bathtub a more finished look. Similar to the gap that can exist between your wall tile and tub, you may have a space between the floor and your bathtub.
This gap may widen over time as your home shifts. Since you are joining two different materials together, you should use caulk in the space where the floor tile and tub meet. If mold gets into that space, it can cause damage to your subfloor. If you see mold forming around where your floor and tub meet, treat it with a mold-killer after removing the existing caulk or grout.
