Installation Procedures
Make sure framed-in alcove is of proper size per Jacuzzi
1
dimensions, square, and plumb; check floor for levelness
(Figure 3). Rough-in should be kept to a minimum until the
unit is on the job site. Measurements may vary +0 or -¼"
from original specifications.
Sufficient clearance must be provided for access to service
2
connections (pump/motor, controls, heater plumbing and
electrical hook ups).
NOTE
Bottom support materials: Casting plaster/plaster of paris (herein
referred as foundation materials) are not necessary but its use is
highly recommended for a firmer bottom support.
In a bucket, mix foundation material. Place a large mound of
3
plaster on the subfloor, in the approximate location of the tub
bottom center. The mounds should be placed high enough so
that when the tub is set, it will cause the plaster to displace
and spread. Replace unit into alcove with front skirt firmly on
floor. Make certain that back ledge of tub rests firmly on
ledger supports. Level unit and shim ledger if necessary. The
bathtub must be level.
A. Drop In Installation
1. Place a piece of scrap lumber on each of the ends of
the cutout – this will be used as a temporary support
prior to lowering the bathtub fully into the opening
(Figure 4).
2. Install the unit, inserting the motor/pump end first,
lowering the bathtub into the opening as shown in
the illustration.
3. The bathtub must be set level. To check, use a level
on top of the ledges on both ends of tub and on top
of threshold (Figure 5).
4. Caulk around the perimeter of bathtub to seal the
space between the rim and the finished deck
B. 3-Wall Alcove Installation
1. Place the tub in the alcove with the front skirt firmly
on the floor. The bathtub must be set level. To check,
use a level on top of the ledges on both ends of tub
and on top of dam (Figure 6).
2. After leveling tub, mark each stud (concrete or block
wall) immediately above the back horizontal flange.
Remove tub from alcove. Measure the distance
between the top of the back horizontal flange and the
bottom of the tub ledge approximately 1½" (40mm).
Carefully mark this dimension on the back studs (or
wall), below the first mark (Figure 6 inset).
3. Install a Ledger Strip: Jacuzzi mandates the use of
supports under the rear ledges of bathtubs to prevent
shifting. Use horizontal ledger strip along the entire
rear ledge or "I", "T" supports in at least two places in
vertical position. Nail a 1" x 3" x 60"
(25mm x 75mm x 1525mm) ledger strip immediately
below the lower marks made on framing
(Figure 6 - inset).
