Get about an extra inch of water depth out of your tub with this handy plate. Strom Plumbing makes this attractive porcelain overflow plate which also stores the rubber stopper when not in use (keeps the rubber stopper out of the way when you want the tub to drain). It measures 3 1/4'' in diameter. When ordered, this overflow plate replaces the plate that comes with the P0007 and P0007E waste and overflow units. If you have any questions or concerns feel free to contact us toll free. There is free shipping on all our vintage bath tub products.
