Water also hydrates the skin and helps pores eliminate toxins. Drop-In tubs have a finished rim designed to drop into a deck or custom surround. They can be installed in a variety of ways like corners, peninsulas, islands, recesses or sunk into the floor. A drop in bath is supported from below and has a self rimming edge that is designed to sit over a frame topped with a tile or other water resistant material.
