The easiest way to install a Whirlpool tub is to select a unit the same size as the existing bathtub. Choosing a tub that differs in size requires moving the drain to match the new tub and sometimes requires enlarging the alcove in which the tub sits. These units are heavy, and some require a bed of wet mortar that conforms to the tub and dries to provide support while others sit directly on the floor.Continue Reading
Consult the new tub's installation kit and determine the location of the centerlines for any new drains or antiscald faucets it requires. Mark these on the floor and walls and install the plumbing to accommodate the tub. If the plumbing in the home consists of galvanized pipe, it is acceptable for use as long as the flow is not restricted; however, it requires appropriate valves or connectors to prevent corrosion where it connects to the copper fittings of the new fixtures. Replace galvanized pipe with another material if it cannot provide sufficient water flow.
The Whirlpool tub combines electricity and water. Install ground fault interrupter outlets to supply power if they are not already in place. Most tubs require a dedicated 15-amp circuit to provide sufficient power for the unit.Learn more about Plumbing
