TIPS FOR LOCATING A WOOD STUD
• If the drywall is exposed, use a stud sensor to locate a
stud.
• If there is tile on the wall, try a stud sensor to locate a stud.
If no stud is found, measure 16" from a perpendicular wall.
Drill a small hole in the grout to ensure the stud has been
found. If there is no stud at this location, bend a piece of
wire and insert it through the hole. Spin the wire to
determine exactly where the stud is located and mark its
location. Patch all holes with silicone to keep moisture out
of the wall.
• If there is access to the backside of the bathroom wall (i.e.
through a closet), measure the stud location and transfer
the measurements into the bath area.
STRUCTURAL REINFORCEMENT SUGGESTIONS
NOTE: Due to variances in local construction methods
and materials used, details given below are suggestions
only. Consult the appropriate local contractor for specific
advice. For concrete walls, you may be able to install
fasteners (such as a wedge anchor) directly into the
concrete wall without modification.
If there is access to the backside of the bathroom wall (i.e.
through a closet) and structural reinforcement is required,
consider cutting a hole in this backside wall to allow access
to the bathroom wall from behind (without having to remove
/ replace ceramic tiles).
1. Choose optimal mounting location of seat including height
(*H) and side to side location (L) as shown in Figure 1.
NOTE: If accessing the bathroom wall from the backside,
transfer the measurements for the support rail location to
the backside wall as shown in Figure 1b. Mark the height
and location on the wall for future reference.
*NOTE: ADA guideline specifies seat height of 17-19"
above the finished floor.
2. Find wall support studs & cut hole in wall board to expose
wall studs as shown in Figure 1. Suggested hole size is
height (A) of 18-24" (48-61cm) and width (B) corresponding
to wall stud spacing. Expose half width of each stud to
facilitate re-installation of wall board patch. IMPORTANT:
Avoid any utilities located in wall!
3. Fabricate a support frame structure from suitable wood
pieces as shown in Figure 2. Support frame width (D)
should fit snugly within wall studs. Support frame height (E)
should be from 24-32" (61-81cm) high or more, depending
on material and stiffness of wall studs. Locate top cross
member (F) to position in line with top hole on the wall
bracket when seat is at install height (H). Lower cross
member (G) should be spaced at C = 14.125" (37.465cm)
center to center from top cross member (see Page 4 for
dimensions of 2 center cross members). Use a generous
quantity of wood screws and glue to hold the support frame
structure together as shown. See alternative to support
frame as shown in Figure 3.
4. Insert support frame structure through hole in wall and
secure uprights to wall studs using a generous amount of
wood screws.
5. Complete the SerenaSeat™ installation instructions on
Page 2. Then, patch the wall cutout (if backside access to
bathroom, consider making an access panel for future
servicing) to match the surrounding wall as shown in
Figure 4.
