The answer to 'which is better grout or' is that both grout and caulk have their own advantages and are better suited for different applications. Grout is a durable, water-resistant material used to fill the spaces between tiles, while caulk is a more flexible sealant used to fill gaps and joints.
Grout is typically the better choice for areas that need to be waterproof, such as bathrooms and kitchens. It provides a sturdy, long-lasting seal between tiles and helps prevent water damage. Caulk, on the other hand, is better for areas that need to expand and contract, like around windows, doors, and fixtures. It can create a more flexible seal that is less prone to cracking over time.
