Retrofit –Existing Shower Replacement
NOTE—In a remodel in which you are not replacing the finished wall surface (tile, or backing material) it is advisable to purchase a PULSE
ShowerSpa model that covers the location of your existing valve assembly—either single handle or two-handle type. If your PULSE
ShowerSpa model does not cover this area, you will need to either choose another PULSE ShowerSpa model that does or make necessary
repairs with appropriate materials (i.e. wallboard, tile, fiberglass, etc).
1. TURN OFF WATER SUPPLY TO SHOWER. Typically there is a gate
valve where the water main enters the house. Turning the water
valve off at hot water tank does not turn off cold water supply
line.
2. Make certain water is completely turned off to both hot & cold
supply lines of shower. Turn shower valve on, both hot and cold,
to VERIFY WATER SUPPLY IS OFF. Open a sink faucet in the
bathroom in which you are installing ShowerSpa to relieve any
pressure and help adequately drain shower supply lines.
3. Remove handle(s) and trim cover(s) of your existing shower valve,
exposing valve body in wall.
4. Locate hot and cold supply lines entering valve. Using a
reciprocating saw with sharp metal saw blade, cut existing
valve out, preserving threads of supply lines entering valve. You
should also cut riser within wall supplying existing shower head.
Carefully twist and remove valve.
5. Unscrew old shower head from shower arm, then unscrew
shower arm from wall.
6. Water lines must be extended to outside of wall cavity, 4" on
center. For best results, attach 90° fittings (available at most
hardware stores) to the stub-outs maintaining ¼" – ½" of space
between fitting and finished wall. The open end of 90° fittings
should point down so supply lines attach parallel to wall.

7a. Mark location of holes for top mount, making sure holes are
level. For a person 5'8" – 6'2", we recommend placing holes of
upper mount at approx. 70¼" above finished floor. 2
7b. To determine location for lower mount measure distance
between indents on bottom edge of horizontal mounting bars
on back of ShowerSpa (approx. 345⁄8
"). Using this distance,
measure down from holes in upper mount to obtain location of
holes in lower mount making certain mounts are plumb.
7c. Use mounts to mark location of holes in each mount.
8. Before drilling holes, make certain connecting to stub-outs DOES
NOT INTERFERE with backside of ShowerSpa and it is flush with
finished wall at desired mounting height.

9. Drill ¼" holes through wall surface using masonry bit. Drill slowly
through wall surface to avoid cracking and chipping. Insert
anchors and securely screw brackets to wall. Before connecting
hot and cold supply lines, hang ShowerSpa on wall, check height
and make sure ShowerSpa is flush against wall with a secure fit.
10. Connect hot and cold water supply lines to stub-outs—DO NOT
OVERTIGHTEN. Before mounting ShowerSpa, check fittings to
make sure they are secure. Turn on water and check for leaks.
When fittings are leak-free, mount ShowerSpa on wall.
11. OPTIONAL—Seal around body of ShowerSpa with a bead of
silicone. DO NOT SEAL BOTTOM.
1Additional fittings or longer supply lines may be necessary depending on your specific situation.
2 The mounting height can vary depending on several factors (i.e. location of supply lines, interference from ShowerSpa plumbing, old valve access area,
personal preference, etc.)
3The desired mounting height of ShowerSpa determines, or is determined by location of the ½" stub-outs.
