Trugard Direct – TruLine Linear Shower Drain Installation

By Grover Koelpin 3 comments


Step one . Choose shower drain placement.
Placement of the Trugard TruLine linear shower drain is ideally at an end
wall, the threshold of a doorway or somewhere in the middle of the shower or
steam room. Step 2. Locate the inside edge of the drain trough. Relocate rough-in
pipe work, if necessary, to align with desired placement of linear drain. Fhe
center of the waste drain line is often located two and a quarter inches from
the wall sill plate, more precisely, locate placement by adding the thickness
of the wall substrate, plus 1/8 inch for the waterproof polyethylene membrane and
thin set assembly, plus the thickness of the tile or stone. Step 3. Cut waste drain
pipe the height. Place the linear drain on the slab next to the waste pipe. Now,
mark and cut the waste pipe a quarter inch below bottom edge of the drain
waste water outlet pipe. Step 4. Pre fit the linear drain, Next, prefit the
linear drain to the plumbing waste line to ensure correct placement and
connection of the drain. Step 5. Protect the cutoff waste pipe. Place a sleeve
coupling or temporary pipe extension to protect the debris from going into the
shortened cut off waste drain pipe. Step 6.
Fill in the block out area. Use sand mix mortar or concrete mix to fill in the
block out area under the linear drain. Step 7. Protect the drain body and flange.
Apply quality painters masking tape and cardboard to the top of the drain
flanges and body to protect and keep the inside drain putty trough and flange
clean from mortar and debris. Step 8. Build the drain body support. Now
prepare a slightly wetter than normal mortar bed sand mix and build a support
base under the linear drain trough and the bonding flanges of the two ends and
back flange closest to the wall. Note: For concrete slab installation, wet the slab
prior to applying the mortar mix directly onto the slab. This will bond
the slab and mud bed together. Step 9. Install and connect the drain
body. Install the TruLine drain body by connecting the drain outlet to the
plumbing waste line. Using a flexible or non hub coupling and by squishing the
drain body down into the wetter than normal mortar bed mix. Step 10. Level the
drain. Next level the drain and pack mortar under the remaining drain flange.
Step 11. Establish mortar bed grade height. Now, establish the grade height,
including a 2% or quarter inch per foot slope toward the drain. Use a chalk line
or pencil in straightedge to create the lines on the walls. Step 12. Build a
mortar bed perimeter guide. Build a mortar perimeter around the floor edges
to the height of the grade lines. Step 13. Complete mortar bed. Use the perimeter
mortar as guides filling in and compacting in the entire mortar bed floor
area, maintaining the quarter inch per one foot slope toward the drain. Step 14.
Install the wall substrate. Install the wall substrate in accordance with local
code requirements, which generally require cement chess backer board or
gypsum drywall board. Note: Trugard vapor shield works on standard green or purple
types of drywall. Step 15. Install a polyethylene waterproof membrane. Now,
install the truguard bonded polyethylene waterproof membrane in accordance with
Trugard systems approved installation instructions notes. Now, remove tape from
the drain before applying thin set to the floor area. Step 15.1. Apply thin set to
the floor area. Apply modified or unmodified thinset mortar to the floor
area from the outer edge of the drain bonding flange outward. For wall
placement, six inches up the wall adjacent to the drain. Note: Do not apply
thin set to the stainless steel drain flange. Step 15. 2. Apply TruSeal
sealant to drain flange. Apply one quarter inch bead of TruSeal sealant
around the drain flange and install the vapor shield membrane. Step 15.3. Place and embed membrane into
sealant. Place membrane onto the floor area, now press down on the vapor shield
membrane, squeezing the sealant sideways, along the drain flange, to completely
cover the stainless steel flange and then embed the membrane into the thin
set mortar in an outward direction, towards the perimeter of the shower floor.
Step 16. Install the tile. Install the tile using best industry practices,
starting on the wall adjacent to the drain. After completing the first row of
wall tile, temporarily install the drain grate to ensure that the drain grate can
be inserted and removed freely with approximately 1/16 to 1/8 inch of
clearance. Step 17. Grout the tile after 24 hours of drying
or curing of the thinset mortar. Grouting of the tile may be completed using
industry best practices. Step 17.1. Use flexible tile grout caulk to grout the
tile and grate tiles. Step 17.2. Use flexible tile grout caulk to growl all
wall to wall and floor wall intersections. Step 18. Caulk around the
tile perimeter to give your tile job a professional-looking installation.
Use painters masking tape as a straight edge around the perimeter of the tile
job and apply the flexible grout caulk, then remove the tape. Congratulations on
completing your single slope watertight and leak proof shower with the elegant
TruLine drain.

Great video. I’ve watch over and over during my diy install. Should there be a STEP 15.4 at 4:25? The video shows sealing the drain with membrane, but not cutting it out before title?
Also, do the floor inside corners get done between floor and wall membrane? Do you have any other pictures/videos of this completed shower? The tile I selected is almost exactly the same and I’d like to see the tile pattern. [email protected]

What a ridiculously confusing installation method.
