Tub boxes that form an access opening around the tub drain in slab floors. The collection includes the LSP Products P-3000 tub box, 14-7/8" x 14-7/8" x 7" deep in a 5 pair pack, and the Oatey 34080 standard tub box in a 12 pair pack.
Set the box before the concrete pour so the tub waste and overflow can be connected later. Check the box size against the tub drain location and the waste and overflow assembly, and confirm the depth suits the drain height. Secure the box so it does not float or shift during the pour.
