Regardless of the material chosen, ensuring that the bathtub is adequately supported is crucial for its longevity and functionality.

                                                                How do you secure a freestanding fiberglass tub?

                                                                Securing a freestanding fiberglass tub involves a slightly different approach than traditional alcove tubs. Begin by ensuring the tub is placed on a level surface. If necessary, use shims to achieve a level position. For stability, it is essential to anchor the tub to the floor if it has a base that allows for this. You can use screws or brackets designed for freestanding tubs, ensuring they are well hidden and do not detract from the aesthetic. Additionally, applying silicone caulk around the base will help keep the tub secure and prevent water from seeping underneath, which could lead to damage over time. Regularly checking the stability of the tub and resealing as necessary will help maintain its position and integrity.
