The answer is generally yes, tiles can increase the value of a house. Tile floors, especially those made of high-quality materials and installed professionally, can enhance the overall aesthetic appeal and durability of a home. They are also typically easier to clean and maintain than other flooring materials, which can be attractive to potential buyers. Additionally, tile backsplashes in kitchens and bathrooms can add a touch of elegance and functionality, further increasing the perceived value of a home.
