How to Install an American Standard Whirlpool Hot Tub


Whirlpool tubs, such as those available from American Standard, can be installed as new unit or used as a replacement for an existing tub. The whirlpool tub is installed in the same manner as a standard tub, except for the electrical connections for the pump/motor. Once you've determined a place for your American Standard whirlpool tub, you can install it yourself.

Things You'll Need

  • Tape measure
  • 2-by-4 boards
  • Circular saw
  • Nail gun
  • Mortar mix
  • Bucket
  • Trowel
  • Drywall screws
  • Power drill
  • Pencil
  • Level
  • Measure up from the floor 19¾ inches with a tape measure and make a mark on each stud, in the enclosure for the tub, with a pencil. This will indicate the location of the underside of the tub deck.

  • Draw a line to connect each of the marks, using a level.

  • Measure the width and length of the whirlpool tub with the tape measure. Transfer the measurements to the 2-by-4 boards. Cut one piece to match the length and two pieces to match the width with the circular saw.

  • Attach the 2-by-4 boards to the line you drew, using a nail gun.

  • Combine the mortar mix with water in the bucket. The mortar should be the consistency of pancake batter.

  • Pour the mortar mix on the floor for the base of the tub. Smooth out the mortar with the trowel. Allow the mortar to dry for at least four to six hours.

  • Place the whirlpool tub in the enclosure so that the rim of the tub is level with the 2-by-4 boards or stringers. Remove the tub and wait another 12 hours for the mortar to harden.

  • Place the whirlpool tub back into the enclosure. Drive drywall screws into the flange of the tub and into the studs with the power drill.

  • Connect the water supply lines and the drain line to the tub. Plug the pump/motor into the electrical outlet to complete the installation.

Tips & Warnings

  • The electrical wiring for the pump and motor needs to be grounded and should be done by a licensed electrician.
