How To Plumb A Bathtub: A Comprehensive Guide

Bathtubs are an essential part of any bathroom, providing a place to relax and unwind. Whether you're installing a new bathtub or replacing an old one, plumbing the bathtub is a critical step that needs to be done correctly. In this comprehensive guide, we'll walk you through the steps on how to plumb a bathtub, from gathering the necessary tools and materials to connecting the bathtub to the water supply and drain. ### Tools and Materials Before you begin, gather the following tools and materials: * Adjustable wrench * Basin wrench * Hacksaw * Level * Measuring tape * Pencil * Pipe cutter * Plumber's putty * PVC cement * PVC pipe (3/4-inch and 1-1/2-inch) * Slip-joint nuts * Tub drain kit * Tub spout * Water supply lines ### Step 1: Prepare the Area Begin by removing the old bathtub, if applicable. Clean the area around the bathtub drain and overflow holes. Make sure the area is level and free of any debris. If you're installing a new bathtub, follow the manufacturer's instructions for preparing the area. ### Step 2: Install the Tub Drain Assembly Apply a bead of plumber's putty to the bottom of the tub drain assembly. Press the drain assembly into the bathtub drain hole and tighten the locknut from underneath. Install the overflow plate and overflow tube according to the manufacturer's instructions. ### Step 3: Install the Tub Spout Using the hacksaw, cut the copper water supply lines to the desired length. Connect the water supply lines to the tub spout using slip-joint nuts. Tighten the nuts until they are snug. ### Step 4: Connect the Bathtub to the Drain Cut a section of 1-1/2-inch PVC pipe long enough to connect the bathtub drain to the drainpipe in the floor. Apply PVC cement to the ends of the pipe and fittings, and then connect the pipe to the drain assembly and drainpipe. ### Step 5: Connect the Bathtub to the Water Supply Cut a section of 3/4-inch PVC pipe long enough to connect the tub spout to the water supply lines. Apply PVC cement to the ends of the pipe and fittings, and then connect the pipe to the tub spout and water supply lines. ### Step 6: Test the Bathtub Turn on the water supply and check for leaks. Use a flashlight to inspect the connections for any water seepage. If you find any leaks, tighten the connections until the leak stops. ### Step 7: Finish the Installation Once you're sure there are no leaks, you can finish the installation by caulking around the bathtub and installing the bathtub surround. ### Conclusion Plumbing a bathtub is a relatively straightforward project that can be completed in a few hours. By following these steps, you can ensure that your bathtub is properly installed and connected to the water supply and drain. If you're not comfortable working with plumbing, it's always best to consult a professional plumber.
