Bathroom plumbing may look daunting but some tasks related to it like installing a bathtub drain are not that difficult to pull off.

A bathtub drain is designed in such a way that water flows to the lowest point in the pipe which is known as a trap. At this point, the heavy sediments will settle while the rest of the water will travel further down the pipe. For some time, this will help your drain from getting clogged. If this is the case, you need to replace the bath drain. Use two pipe wrenches in case it is made of metal.

Turn the wrench on the pipe that will be removed while also holding the other wrench still. Connect a PVC tub drain kit to the tub. Both the upper cover overflow plate and drain assembly retrofits over the original. Spread silicon on the gasket then use a screwdriver to tighten the plate. Use a pair of screwdrivers to screw the tub drain basket.

Apply silicon on the gasket where the pipe links to the basket and use tongue and groove pliers to tighten the fitting. The tee-fitting will then be connected to the overflow pipe and the tub basket drain pipe. Use pliers to tighten the connecting nuts. Some tubs may have a strainer grid that first needs to be removed before you can assess the drain fitting. First, determine which end of the wrench will fit inside the drain opening and around the drain fitting's crosshairs.

Insert the wrench into the tub drain and align it with the crosshairs, then use channel-type pliers or an adjustable wrench to rotate the drain fitting counterclockwise and loosen the fitting. It will unthread from the tub shoe below the tub. Keep turning until the fitting comes free. It is best to have a clean surface to work with, so be sure to remove as much of the putty as possible.

Use the old fitting to determine the size of your drain. A bathtub drain converter kit often provides drain threads in two sizes to accommodate different tub drains. Select the appropriate thread attachment.

Remove the tub stopper from the new drain fitting—often this is a matter of simply unscrewing it. Insert the fitting into the bathtub drain opening, making sure to center it. Make sure to thread the fitting into the shoe carefully. A good way to avoid cross-threading is to start tightening by hand first. When it looks like the fitting's threads are screwing properly into the drain shoe, you can continue tightening by using the tub drain wrench.
