American Bath Factory Sistine Stone Double Corner-Hdm User manual

Congratulations on the purchase of your new shower system.
This guide will give you the instructions on the installation of your new shower.
Natural Travertine Stone Appearance
All of our stone products are custom made and hand-crafted to look and feel like authentic
travertine. As you may know, travertine is a form of limestone that has been under pressure for
thousands of years. The product of long-ago hot and cold springs and waterfalls, travertine is a
beautifully banded and colored stone with a unique character. Among its most appealing
characteristics are the interesting craters and depressions, created by streams of water that
flowed through the stone.We have taken great care in reproducing the appearance of genuine
travertine stone, giving you a beautiful and authentic shower.
Installation time may vary depending on your experience, complexity of shower,
and “Pre Installation Preparation Work” which may include: plumbing relocation,
drain location and bathroom demolition.
Prior to demolition, scheduling a contractor or building your shower, double check that you
have all the parts from the factory. Some applications may require a licensed plumber or
contractor. Do not use any product spec sheets to begin installation before receiving product.
These spec sheets are for reference only. Use actual product measurements only.
The diagrams throughout this guide illustrate a 36” x 36” shower. Depending on the size of the
shower purchased, actual parts may vary in size from the diagrams shown.
Our goal is to help you achieve a quick and successful shower installation.
See the clock in each section for estimated installation time.
Missing or damaged hardware and tiles should be reported within 24 hours
of receiving this shipment - If you need assistance call 1.800.454.2284,

This shower system is designed to be installed on a bare floor. It is necessary for any existing shower to be completely removed.
Tear out and remove all old material to expose the 2 x 4 wall studs. Clean up the shower area, removing all dust and old material from the area.
4DRY-FITTING THE PAN TIME REQUIRED
½ to 1 HR
It is easier to check alignment of studs and pan without the drain installed into the pan. Place the pan in the planned position. Check to see that the spacing
between the pan and 2 x 4 studs are flush. Some shims may be required to plumb walls with the pan. By screwing in the 1/4” cement board the metal flange
will pull fast to the studs, and will secure the metal pan in place. (diagram 1)
With the pan in position, check to make sure the 2” drain pipe is in the center of the pan drain hole. (diagram 2) Use the drain collar #5 by itself; remove the
rubber seal, nut and gaskets from the drain assembly. (diagram 3, next page) Push the drain collar #5 into the drain hole between the pan and the 2” pipe.
With the drain collar pushed flush to the pan surface, the 2” drain pipe should not extend past the inside threads of the drain collar #5.

8CEMENT BOARD INSTALLATION TIME REQUIRED
1-2 HRS
Use 1/4” thick cement board as your shower backer. Using this backer will comply with almost all city codes. A cement-based product like Wonderboard or
Hardibacker may also be used if it meets your local codes. Some codes require a vapor barrier to be installed as well. We recommend a water/vapor barrier of
6 mil. plastic be installed before installing the cement board. To do this, staple plastic so that it hangs 1” above the floor. Roofing nails may be used to attach
the cement board instead of screws, this prevents the plastic from wrapping around the screws.
diagram 5
apply silicone
1. When installing pan, use high quality thinset or silicone.
2. Due to the nature of fiberglass, slight bowing or uneveness can occur in storage, installation of
the pan will address this issue.
For best cutting results for wall panels and cement
board, use a Makita grinder with a 4” tile blade.
set cement board inside of pan here.
1. IMPORTANT: Use your cement board as an indicator of squareness. The cement board comes in
square sheets. If you see gaps or areas where the cement board is not fitting flush, fix
the problem by removing the cement board and shimming the board until it’s square and
flush. If the seams of the cement board are not flush and square, your wall panels will not
be square and flush.
2. Place a bead of silicone on the front inside face of the shower pan flange. The bead should be in
a zig-zag pattern.
3. Place the cement board against the studs and rest it INSIDE the shower pan against the back
flange. Attach the cement board to the studs with screws or nails. Do not screw or nail into
the shower pan flange.
4. Continue installing the remaining cement board.

9SIDE THRESHOLD PLUMB LINE TIME REQUIRED
½ HR
6
To help with the wall installation, use a level and draw a plumb line from the inside of the floor
threshold up to the top of the shower. Do this on both sides. This line will be where the side threshold
and the wall panels meet, this will give you a visual reference point when dry-fitting your wall panels.
WALL PANEL/LINER INSTALLATION TIME REQUIRED
3-4 HR
A - Inspecting Wall Panels/Liners
Inspecting panels at this point will give you confidence that the wall panels are straight and square from the factory. When installing wall panels, you may need to
make adjustments to the panels to accommodate for unevenness of your existing walls. During the inspection process and/or dry-fitting process, if you have any
concerns about the alignment or fit of the wall panels, please call 1-800-454-2284 for customer service, and we will gladly assist you with your installation.
1. Find a large empty area to layout and inspect all panels.
2. Align all panels and liners to check for straightness. Make sure grout lines are straight and square
to each other.
3. Sistine Stone wall panels are made to be flexible. (Warning - Store on a flat area.) If wall panels
have been stored improperly or seemingly have become extensively bowed, they can be easily
flattened before installation (See troubleshooting section on last page for details).
B - Test Alignment by Dry-fitting Wall Panels/Liners
1. Place your first bottom panel 2B into position. (diagram 7). Rest 2B panel onto the pan floor;
use spacers between the floor and the panel to make the top of the panel level.
2. Place the second bottom panel 1B into position, push the two panels together. Make sure the
grout lines are aligned, use spacers to make the top of the panel level. Inspect the spacing
between the wall panels and the side threshold plumb line.
3. Depending on your cement board alignment, some sanding of the wall panel edges may be
required for a tight fit.
4. Place liners 1L and 2L in position check for level and length.
5. Place 2T into position. (diagram 8)
6. Place 1T into position. Depending on your faucet selection, you may need to mark and cut out
holes for your faucet to fit through before you can place the panel into position. Remember
“measure twice, cut once”, you can cut our walls with most cutting tools. (See installation
video at www.americanbathfactory.com). Now you can check for level, grout line alignment and
spacing between walls and plumb line.
7. Check that 1LT & 2LT (top liners) fit properly on top.

SILICONE RECOMMENDATIONS
We recommend using GE Silicone II Window and Door 100% Silicone throughout this installation as well as for your wall panel silicone.
During our tests we have found that using this silicone gives the best results. Use this silicone whenever the installation guide refers to the use of “silicone”.
Depending on the size and threshold type of your shower, you will need from 10 - 20, 9.8 oz. tubes of silicone to complete your shower installation.
DO NOT USE any Mastic, Mortar based Thin Sets or “Liquid Nails”. These will not cure properly between the two non-porous surfaces of the shower.
The use of a Water Barrier will also adversly affect the bond between the wall panels and the cement board.
Warranty coverage only extends to the brand and type of silicone we recommend and applied
per the manufacturer’s directions and recommendations.
Recommendations for applying GE Silicone II Window and Door 100% Silicone to Wall Panels
1. Apply a 1/4” thick continuous bead of silicone along the perimeter of the wall panel, 1/2” in from the edge.
2. Use a zig-zag pattern to cover the rest of the backside of the wall panels, leaving 3”- 4” between each 1/4” bead.(diagram 9)
3. Also apply silicone to the cement board. Apply in the same manner as steps 1 & 2.
It is very important to ensure complete coverage of silicone to achieve the best bond. The steps listed above are only recommendations and are meant to
supplement the specific manufacturer’s directions.You may need to brace the wall panels in place while the silicone dries. Refer to the manufacturer’s
recommendations for coverage of the silicone to determine the proper amount you will need for the project based on your shower size.
Depending on the size and threshold type of your shower, you will need from 10 - 20, 9.8 oz. tubes of silicone to complete your shower installation.
Tips for bracing Wall Panels
If you use the recommended silicone, and apply it correctly, the wall panels will stick to the walls without any bracing required. If the studs or cement board
surfaces are not perfectly even or square, the edges of the wall panels may not stay flush. If this happens, we recommend using a brace to hold the wall panels in
place until the silicone dries. Your bathroom layout and shower style will determine the method you use to brace the wall panels.
1. Always protect the wall panel tiles and shower pan floor from damage. Make sure the braces will not scratch the wall tiles. Use a piece of plywood or
a 2 x 4 to distribute the force across the largest surface area.
2. Brace the wall panels using a horizontal brace from one wall to the opposite wall.(diagram 10) Measure and cut a 2 x 4 or use an expandable curtain rod
or telescoping painter’s pole. Cut the 2 x 4 larger, so it has to be pushed into position or use shims to apply pressure on the wall panels.
3. Brace the wall panel from the shower pan threshold to the wall panel. Measure and cut a 2 x 4 to fit between the shower pan threshold and the wall panel.
Apply weight downward on the wall panel side or place a 2 x 4 vertically between the ceiling and the top of the brace. Push down on the angle brace and
Measure and cut a 2 x 4 screw it to the vertical 2 x 4 that is pushing on the ceiling. (diagram 11)
4. Leave the braces in place until the silicone has completely dried. Refer to silicone manufacturer recommendations for drying time.

C - Installing Panels
8. Sand the backside surface of the wall panels with 60 grit sandpaper. This will increase the bond
to the silicone. Remove all dust and dirt with a clean dry cloth.
9. Start with panel 2B, apply a generous amount of silicone to the cement board and to the back
side of the wall panel. Refer to “Silicone Recommendations” on previous page for applying
silicone. Also refer to the manufacturer’s recommendations for application and drying time.
10. Press the wall firmly into position. Be sure to use spacers between the bottom panel and the
shower pan to ensure panel is level. (diagram 12)
11. Install the remaining panels in the following order: 1B, 2L, 1L, 2T, 1T, 1LT & 2LT.
Match the space between the panels with the rest of the grout lines on the panel.
Use spacers if necessary to make the walls square and straight.
THRESHOLD TRIM TIME REQUIRED
1/2 - 1 HR

The threshold trim pieces complete the look of your new shower system. If you purchased a Basic
Package which does not come with glass, your threshold pieces will be solid, without a channel. If
you purchased a Supreme Package which comes with glass, the threshold pieces will have a channel
for the glass panels. No matter what package you ordered there are 2 special cap trim pieces and 2
special notched bottom left and right pieces.
1. Locate all the trim pieces and align them on the floor. (diagram 13)
2. Apply silicone, using a zig-zag pattern, to the cement board along the panel’s edge, approximately
4 inches out: to the far outside of the shower pan. (diagram 14)
Do not install the small cap trim pieces if your package includes glass. These trim pieces are to be
installed after the glass and door have been installed. If you did not purchase a package
with glass, you can install the cap trim pieces as outlined in step 4 below.
3. Starting with the special bottom threshold piece, place the threshold into position making sure to
align the threshold with the vertical plumb line previously drawn on the cement
board. Apply pressure to the trim piece to bond it to the cement board. The trim piece should be
flush with the inside of the shower pan threshold. (diagram 15) Make sure to align the glass
channels in the thresholds with the glass channels in the shower pan. (if glass unit)
4. Place the remaining trim pieces into position. Make sure to use a level and the plumb line
previously drawn on the cement board to align the trim pieces vertically.
Wall thresholds should be flush on the inside and
outside of the pan

4. On the 2 tiles the Shampoo Shelf will be replacing, mark 1”
from the outside of the grout line, the cut-out area will be
10” x 22”. Cut out the hole for the Shelf. The smaller the
hole the better.
5. Dry-fit the Shampoo Shelf for alignment of grout lines.
6. Silicone in-place with a generous bead around the back of the
lip, wipe off excess silicone with tissue.
1. The Shampoo Shelf was designed to match your tile size.
(2) 12” x 12” tiles, the cut-out hole size is 10 x 22”.
2. There is a 1” lip or frame around the Shampoo Shelf, this will
be the water sealed area for the Shampoo Shelf.
3. The best way to cut the hole is with a small 5” round
diamond blade, and with a jigsaw to cut the corners.

A - Handle Installation
1. Set the glass door in a position to enable the assembly of the handle. (diagram 16)
2. Loosen the set screws so you can separate the handles.
3. Unscrew the long bolt from the handle. Keep all rubber pieces attached to the bolt.
4. Remove the first set of flat, clear washers from the bolt.
5. Start with the top hole on the glass door. Place the long bolt through the hole in the door
(keeping the remaining rubber pieces on the bolt). On the other side of the glass place the flat
washers onto the threaded portion of the bolt.
6. Take one side of the handle and screw the long bolt into the end. Just start the bolt until a few
threads catch. Keep loose.
7. Put the second bolt through the lower hole. Place the flat washer onto the bolt. Screw the bolt
into the bottom handle.
8. Align the handle on the door and carefully tighteb the long bolts. Do not over tighten.
9. Place the opposite handle over the long bolts and tighten the set screws to secure the handle.
B - Hinge Installation
1. Locate the top hinge and remove the side plate by loosening the two screws. (diagram 17)
2. Place the hinge into the top cutout on the door so the screws will be facing into the shower
and install the side plate. Tighten the screws until the hinge is secure. Make sure the hinge is
centered in the cutout and that the screws are facing into the shower.
3. Repeat these steps for the bottom hinge.
Be careful not to rest the edges of the door on hard
surfaces. Tempered glass is very strong and impact
resistant but its weakest point is impact on the edges.

C - Door/Side Glass Installation
1. You need to dry-fit the door to check for alignment. Install the door with a 1/2” gap from
the pan threshold and bottom of the door, the front glass panel will be flush and matches the
door in height. To start, place the front glass panel into the channeled pan threshold. Find some
1/2” spacers, a piece of dry wall or plywood works well, place the spacers onto the pan
threshold where the door is going to be located (2 people are required). Rest the door onto the
spacers. Align the hinges to the side threshold, using a level to check if door is plumb. The front
glass panel will need to be adjusted to be flush with a 1/4” gap between the door and the
glass panel. Using spacers under the side glass panel, align the top of the glass door and the top
of the front glass panel to be the same height.
2. Once the shower doors and the front glass panel are aligned, mark the location of the hinge
holes using a pencil. The marks through the holes onto the side threshold will be used to pre-drill
for the screws that attach the hinges to the threshold. Remove and set aside the door.
3. Pre-drill the holes for the hinge screws, you will drill a hole through the stone side threshold;
making the hole large enough that the screws do not bind in the stone. Drill only through the
stone, your screws are going to anchor into the studs behind the decorative stone threshold.
4. Re-align the door and install screws in hinges.
5. Install the door sweep onto the bottom of the door, with the water flap facing the inside of the
shower. Adjust the door sweep so there is enough friction between the door threshold and the
rubber flaps to keep the door secure when closed, but not too tight as to make the door difficult
to close or open. This is done by pushing the seal up or down onto the glass door.
6. Gently insert the 2 side glass panels into channels in pan and side thresholds. Adjust the side
glass panels so they are level with door and have an even 1/4” gap between the door and
the side glass panels. Adjust height and level if necessary. After dry-fitting the side panels into
the correct alignment, remove the glass, and place a 1/4” silicone bead into the channels.
Re-insert the side glass panel. Install the glass support bracket to the top of the 2 side panels.
(diagram 20) Check alignment again. Wipe off excess silicone. Let dry.
We have provided door seals for water sensitive areas such as wood floors. If glass panels and door
are installed correctly with the proper spacing, outside water spillage will be minimal and the side seals
won’t be necessary. The door sweep is what keeps the door closed. Adjust tension as needed. If you
would like to use these side seals, follow the steps below.
7. The L shaped seal goes along the hinge side of the door on the threshold trim pieces.
(diagram 18)
8. Place the seal along the edge of the glass and cut the seal to the proper length.
9. Remove the backer from the seal exposing the 2 sided tape, only remove a small amount at a
time.
10. Starting from the top, align the seal along the edge of the door and stick the seal to the
threshold.
11. Work your way down the door. Do small sections at a time, slowly peeling the backer off the
seal.
12. Locate the plastic H shaped seal. It goes on the door strike side, opposite the hinge.
(diagram 19) Measure and cut the seal to length.
13. Starting from the top, push the seal onto the door, slowly working your way down the door.

SHOWER SYSTEM TROUBLESHOOTING
DO NOT CLEAN SISTINE STONE WITH PAINT THINNER, ACETONE, LACQUER THINNER, M.E.K., SCRUBBING BUBBLES
or other chemicals that attack the structural integrity of Resin Based Stone. Use of these chemicals will destroy the surface of the stone and void
your warranty. Soapy water, ammonia based cleaners or cleaners like “Formula 409 Natural Stone Cleaner” will remove most dirt and residue from
all types of finishes. For stubborn stains you may use a non-abrasive Scotchbrite pad. “Lightly” scrub the stained area in a circular motion to avoid dis-
coloration. The stone is naturally waterproof and will not absorb spills or soil, simply wipe away with a damp sponge. Periodic cleaning with a sponge
and warm, soapy water will remove any build up of dust or grime.
CARE & MAINTENANCE OF YOUR SHOWER SYSTEM
Your American Bath Factory shower has a non-porous tile surface, which makes it easy to clean. Grout used must contain an ACRYLIC ADDITIVE to
ensure proper bonding to the tiles.
1. Linen Tile & Grout Caulking is available at www.americanbathfactory.com. For Natural Sistine Stone use Snow White Product No. 15302,
for Medium Sistine Stone use Linen Product No. 15303.
2. Follow the grout directions for specific application instructions, a water-based non-sanded grout is recommended.
3. If you desire a powdered grout, use an acrylic additive to ensure bonding.
Note: Grout is not covered by ABF Warranty.
Correcting Bowed Wall Panels Sistine Stone Wall Panels are made to be flexible and may have a slight bow. This condition is normal and the
panels will flatten when properly installed. If the panels have been stored improperly or have become excessively bowed, follow instructions below.
Using a heat gun or propane torch, heat the backside of the panel in the most bowed area. Hold the torch a few inches away and move the torch back
and forth over the area. After the panel becomes malleable, lay panel on a flat surface and apply weight until cool and flat.
(wall thresholds work well, refer to Installation Guide Packing List).
Cracked Tile As with any tile project, a tile can become damaged. We have supplied extra tiles in your package if this happens. Simply cut out the
damaged tile, silicone a replacement tile in place, and grout.
Cracked Wall Panel Seam If your wall panel developes a crack in a grout line, simply grout over the cracked seam when it is installed. The grout
will correct the problem, you will not be able to tell the crack was ever there.
