Installation Instructions
Goof Proof Shower Seat
®
Mark E Industries offers the choice of either of 2 sizes integrated into the same
seat. Simply choose the existing standard full-size 30” or 24” seat which can be
cut from within by cutting along the guidelines shown on the seat surface. Use a
diamond wheel grinder or circular saw and nish the cut with a hacksaw blade.
New Installation Instructions Using Wood Backing
(Structural integrity is greatly enhanced with the use of blocking)
Preparation
• Before installing wall boards, determine desired height and position of seat. (We
recommend a height of approximately 19 inches above the anticipated nished
shower oor tile in a corner opposite or
farthest from the shower head). Height of the
seat should be coordinated or considered, if
possible, with wall tile layout in order for the
seat to rest on top of a full tile course for ease
of installation and appearance.
• Install 2x4 or 2x6 blocking between the
vertical wall studs, at least 24 inches (18
inches for the 24” seat) out from the corner of
adjoining walls, for the attaching screws.
• The horizontal top edge of the blocking
should be 1 inch above seat position for 2x4, 2 inches above for 2x6. This is to en-
sure that the attaching screws strike the optimal point in the blocking.
Shower Seat Installation
• After wall boards are installed,
locate and mark the position of the
blocking. Remember the top edge of
the seat should be 1 inch below this
mark. (This guarantees the screws are
properly placed for strength into the
blocking). Layout and begin wall tile
installation.

• A continuous bead of an adhesive
caulk is to be applied on the back
sides of the seat, where the seat
contacts the wallboard.

• With the seat situated on top of the tile,
level the seat by the incorporated bubble
vials and screw seat through wall board
and into the blocking (Use supplied
shims if wall is not square). The seat surface has been pre-sloped to ensure wa-
ter run-off. The bubble vials have accounted for this and should read level after
installation.

(Be sure to break or cut off shims
ush with top of seat after secured)
• Using latex modied thin set mortar, skim
coat the top and front of the seat before setting
the seat tile with the same mortar.
• Tile the seat, then continue the wall tile
installation. (The seat tiles should be under
and behind the wall tiles according to proper
tile installation procedures).
• Grout after mortar has set.
First determine in which corner the seat will be installed
and its height above the oor. (approximately 19 inches)
