A stone resin tub is moulded in one piece, so the only hardware that shows is the drain sitting in the middle of the floor. This one keeps that spot quiet: the lid is 2.76 inches across, painted matte white on both faces, and it drops level with the rim instead of standing proud. Press it once and the seal closes for a soak. Press again and the plug lifts, letting the water go. Under the lid the body is machined from brass, with a threaded shank and a nut that pull the two halves together against the tub shell. Total height is 3.54 inches, so there is room for the thread to pass through a thick resin base. No overflow plate is included, which suits freestanding tubs that have no overflow cut out. The unit weighs 0.6 pounds.
