Badeloft's UB-05-M undermount ramp sink sits flush beneath your countertop for a clean look. The ramp basin slopes gently toward the drain, so water flows out completely without pooling. Stone resin is non-porous, meaning it won't stain or absorb moisture over time. An integrated overflow adds protection against accidental spills. Includes mounting hardware for undermount installation. Backed by a 10-year residential warranty.
