IMPORTANT! Before installation begins:
NOTICE: Please inspect the unit thoroughly before installation to make sure it has not been damaged during transportation.
If you have any questions please call Aquatic’s Technical Services department at 800-945-2726.
a. READ ALL INSTALLATION INSTRUCTIONS COMPLETELY. IMPROPER INSTALLATION WILL VOID THE WARRANTY.
b. Make sure that walls and floors meet fire safety requirements of local building code and/or FHA/HUD Minimum Property Standards.
c. The blocks and/or legs attached underneath the bottom of the bath fixture are an integral part of the support system and should not be removed.
Although these blocks and/or legs need not touch for an acceptable install, this may be an indication that the unit and/or sub-floor are out of level.
NOTE: No foundation materials are required on Aquatic bathtubs.
d. For three wall alcove installations, use only integral molded three-sided tiling flange bathtubs.
e. Aquatic does not recommend utilizing bathtubs without an integral tiling flange in an alcove installation where a shower
head would be installed above the unit and utilized as a shower.
Tools Needed:
Drill, 3/16” drill bit, screw driver bit, 3 1/2” drill bit, 1” drill bit, #8 x 1” pan head screws, tape measure, hammer, 100% mildew resistant
silicone sealant, level.
Pre Installation Requirements:
a. In remodeling, if necessary, add studs at each end to provide a vertical nailing surface for the side nailing flanges of bath fixture product.
b. To avoid obstruction during installation make sure that supply lines, spout pipe and valve plumbing do not project into alcove.
c. Tubs require a 6” x 12” (150mm x 305mm) floor opening for the 1fi” (40mm) drain, waste and overflow (DWO) kit. [See Diagram 1]
NOTE: Be sure floor opening location matches bath fixture drain location.
Installation
If mounting fittings on tubs, from stable reference points (back wall studs, floor) measure the locations of spout and valves.
Note measurements here:
Tub Filler: ____________________________ Valve: ______________________________
n Make sure framed-in alcove is of proper size per Aquatic dimensions, square, and plumb; check floor for levelness.
n Place the tub in the alcove with the front skirt firmly on the floor. The bathtub should be set level. To check, use a level on
top of the ledges on both ends of tub and on top of dam. [See Diagram 2]
n After leveling tub, mark each stud (or concrete or block wall) immediately above the back horizontal flange. Remove tub
from alcove.
n Measure the distance between the top of the back horizontal flange and the bottom of the tub ledge (approximately 1¹⁄2” (40mm)). Carefully
mark this dimension on the back studs (or wall), below the first mark. [See Diagram 3: Detail A]
n Ledger Strip: Aquatic 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” or “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.
NOTE: Fasteners: To wood framing - 1” (25mm) galvanized roofing nails or 1” (25mm) pan head screws; to steel studs - drill
flanges and studs with ³⁄16” (5mm) carbide bit and fasten with #10 x 1” (25mm) sheet metal screws with washers; to concrete/block walls
use 1” (25mm)concrete nails with nailing tool or impacter. NOTE: Pre drilling nailing flanges is recommended to avoid cracking the unit.
n Replace unit into alcove with front skirt firmly on floor. Make certain that back ledge of tub rests firmly on ledger supports [See Diagram 3:
Detail A]. Level unit, shim ledger, if necessary. The bathtub should be set level.
n a. Spot-fasten the two bottom corners and the two top corners of the vertical side nailing flanges.
b. Fasten at each stud through the topside flanges; through the back flange, at each stud (concrete; 16” (405mm) on center),
working from both ends toward back center.
c. Complete the fastening through vertical side flange, approximately 8” (205mm) on center.
n When other than cementitious backer board plaster is to be used, furring strips as thick as nailing flanges are recommended for installation
on studs above the installed AQUATIC unit to assure walls will be flush. 100% silicone sealant with mildew resistant properties should be
applied between the backer board and horizontal surface of unit. Then finished wall materials can be applied [See Diagram 4: Detail A].
Finishing of other trades should be done in conformance with applicable codes and generally accepted building practices.
