Solidly built from melamine laminated plywood. The drawer hardware has the soft-close feature, so that was an added bonus (we didn't see this in the product description). Due to the height of cabinet bottom, interfering with my drain pipe, I had to make some adjustments to make it work (see attached photo, before top was attached): I had to notch the trim at the bottom of the cabinet at the wall (the horizontal wall tub sits 1/8" above the cabinet bottom) and cut two 2" holes to accommodate the p-trap, which now sits below the cabinet bottom. Fortunately, the latter is not visible unless one crouches real low. This six drawer pulls came with only five mounting screws so installation involved an extra trip to hardware store. Also delivery took seven weeks so project completion was delayed. But we sure like the look.
