What is the best tub and tile caulk?

Similarly, it is asked, what caulk should I use in shower?

Tubs and showers require a special caulk that contains mold and mildew prevention additives. The tubes are usually labeled “for kitchen and bath use.” Most are 100 percent silicone, but you can also find some latex versions. Latex caulk is easier to tool and cleans up with soap and water.

Furthermore, should you use grout or caulk around a bathtub? Since you are joining two different materials together, you should use caulk in the space where the floor tile and tub meet. Grout is not flexible, so it's not the best material for the job, while caulk allows for movement and also provides a better sealant.
