Whirlpools, also known as jetted tubs, are bathtubs with jets of water that massage you as you bathe. The overall plumbing of a jetted tub is the same as a conventional tub, although there are a few additional considerations, such as for the electrical needs of the whirlpool motor. Proper installation will ensure that your tub lasts for years to come and increases the value of your home at the same time.
You have two choices when installing a jetted tub. The first is for tubs that have flanges meant to be attached to the wall studs. The frames for these tubs are generally just large enough to provide a base for the tub to rest upon, as well as a frame for the face of the tub.
Tile or other material is usually installed here. The second type is a top-setting tub, which rests on top of a platform that sits on top of a custom tub frame. The dimensions of your tub platform are entirely up to you, so long as the basic rules of framing are followed for the supports. A template is included by the manufacturer, or you can measure the lip of the tub and cut the hole so that the tub is resting on top of the platform.
Jetted tubs require a motor to run the jets, so there needs to be an electrical outlet inside of the tub framing. The best place to mount this is by the motor, as high up on the tub frame as you can without getting in the way of the motor or the tub itself.
This will allow thickness for top and bottom plates. If there is a variation in floor height, you can add an extra 5mm. Finally, nail the studs between the top and bottom plates and assemble two sides of the frame.
Position one side of the frame against the wall, and the other side paralleled to it. The distance between both sides should be by the width of your tub, minus 30mm. That means excluding 15mm on each side. But why is that? Well, when you place the tub onto the frame, it needs something to sit on.
Once the position of the frames seems accurate, nail them with a nail gun into place. Once you have placed the sides in their places, you will be able to measure the distance between the sides at the ends. Cut the top and bottom plates of both sides and three vertical studs for each end. Then nail the studs between the top and bottom plates. Use a spirit level if the vertical edges are in the proper position. And finally, place your drop-in tub to make sure it sits properly on all four edges.

If you know how to build a frame for a drop-in bathtub, you must have some carpentry skills. But it does require precision. Place the tub where you want it to be. If you are going to install it against the wall, make sure it is at least inches apart from the wall. Usually, the manufacturers provide the instructions. The measure and cut the timbers to build a frame much like the steady drop-in bathtub frame.
The studs should be 16 inches apart. Now position the frame where you want to set and mark around the existing wall. Remove the frame and then remove the existing wall with a drywall knife. It will expose the structure behind the wall. Again place the frame in the right place and use a spirit level to check if it is leveled correctly. If everything looks accurate, screw the frame on the floor and to the wall studs. Then cut the plywood with a circular saw.
A cut-out template of the tub comes with the packaging. Place it on the plywood sheet and trace the outline with a pencil. Then using a jigsaw cut along the line.
But what if there is no template in the package? In that case, try the following:. The instructions will tell you what measurements you must follow to cut to insert the lines for the faucet and drainage lines. Once you have done those, set the tub onto the platform. After everything is done, screw the plywood on the frame. Then clean out the area and fill the tub to overflow level to check if it is placed correctly.
Let the water sit for some time to make sure it is watertight. Then empty the tub. If you see it drained utterly, that means it is leveled. Now that your platform is complete, you can decorate it with your chosen material or tiles.
The best way to support a drop-in tub is to use a mortar base or mud. Some people use spray foam , but I do not recommend it.
Because the foam expands unevenly, and it does not create a strong base. Lay a plastic sheet on the subfloor. It will prevent moisture from damaging the floorboards. Lay a few shovelfuls of mortar where you have marked the tub area. It has to be enough to create a inches thick base. Cover the mortar with another plastic sheet to prevent it from sticking to the tub. Place the tub on top of the base support.
You can use a spirit level to check the balance. And then fill it with water. Let the water sit on the tub for at least 72 hours. After the mortar support base is thoroughly dried, you can drain the water and start using your bathtub. Since you are trying to find out everything about drop-in tubs, you are definitely looking forward to installing one at your home. Move it down as low as possible but only to where it lays flat.
Mark a spot with a pencil at the top of the suction cover. Remove cover and measure 2 inches straight down. Determine where the jets will be placed. This is a matter of personal preference. We advise placing them at your ankles, knee and hips. This control is located on the top of the tub deck, close to the pump, and within easy reach of the access panel. Mark with pencil.
Starting from the inside, drill all the jet holes. Drill slowly and deliberately. Maintain a tight grip on the drill. Take all measurements carefully. Measure the distance between the jet holes on one side of the tub. Measure from the right side of the hole to the left side of the next hole. Under no circumstances should you use center to center. Tape measure should remain on the surface of the tub at all times so that the measurement is accurate.
Adjust as needed. Repeat for the other side if needed. See Diagram. Prime both ends of the hose you just cut. Align the Venturis before the glue sets. Position the assembly as it will conform to the tub either on the right side or left side — — remember that the large opening in the VENTURI is where the jets will enter.
Use the adhesive contacts and zip ties to hold each check valve in place. The long end of the hose should be toward the pump. Now retrieve the strings form inside the walls through the jet holes. A hanger or handle of a paint can or bucket will work great. There is no such thing as applying too much caulk here.
