Shower Base Installation Video


Before you begin

  • Make sure your subfloor is sound and level.

  • Make sure you install your drain first.

Installing the drain

Install your drain or have it installed by a professional plumber as pictured above

  • A) If the base is going on the wood subfloor, cut a 5” round hole so that the flange of the drain is supported on the floor.
  • B) If the base is going on a concrete floor, where there may be a larger hole in the floor, you must make sure the drain is supported.
Ways of Doing This :-
  • a) Attach the drain to your plumbing, making sure the flange is at floor height. Then fill the hole in the cement with either sand and pack well or fill with cement.

  • b) Fill the hole with framing and plywood allowing the drain flange to sit on the plywood.

  • c) Lay a full sheet of ½” or thicker plywood in the full shower area. Fasten the plywood to the floor using thinset. Then cut the 5” round hole and install the base using the thin-set. Once the base is installed on top of the plywood, you won’t even know that it is there.

4 SIMPLE steps of installing the base

  • Step 1) Trowel a moderate amount of modified thin set into the area using supplied ¾” notched trowel.
  • Step 2) Place supplied gasket on top of drain flange.Before you set the base in place.
  • Step 3) Ensure the shower base is firmly embedded into the thin-set.
  • Step 4) Clamp the drain to the shower base using the drain’s clamping ring.

Installing the SimpleWall

Once the pan is installed, starting with the back wall, put a bead of the sealant along the step joint of the pan.

Stand the first panel in place with the step joints overlapping.

Put 1 screw with a washer at the joint of the pan and wall panel on each stud.

Put 2 more screws with washers up each stud, about 10” apart, leaving the top one for now.

Next, put a bead of sealant along the step joint of the panel you just installed.

Stand the next panel in place and screw to studs the same as the lower panel.

Repeat for the third panel (you will need to cut this panel to the height of ceiling)

You should have 10 screws with washers vertical on each stud.

Once the back is finished, put a big bead of sealant up each corner.

Now you install the side panels in the same manner as the back wall, As you set the side panels in place, you would press the panel into the bead of sealant in the corners.

Once all the wall panels are in place, Cover each screw and washer with sealant.

Smooth out the sealant on the joints and screws with a trowel.

If using other tile backer board, waterproof as below.

Waterproofing the walls

(not necessary when using the SimpleWall tile backer)

Complete your shower system by waterproofing the walls with our Aqua Defense roll on / paint on waterproofing rubberized membrane.

The waterproofing kit comes with 75’ x 6” wide fabric for the corners and joints.

If you are using a waterproof tile backer board, all you really have to coat is the corners, joints, and screw holes.

With non waterproof board, you should paint the complete walls.

It is also good to waterproof the tile backer board to the base to create a second barrier of protection.

Installing a Shower Seat

  • Step 1) Trowel some thin-set on the floor and wall where the seat will go.
  • Step 2) Press the seat firmly into the thinset and allow to cure.

Installing a shampoo Niche

  • A) Before tile backer board
    – Screw niche into wall studs in desired location. Leave niche sticking out of wall by ½” to be flush with tile backer board once finished.
  • B) After tile backer board
    – Determine the best spot to your preference where to put the niche. Keeping in mind where the studs and water lines are. Trace the outside of the niche and cut the hole in the tile backer board. Insert the niche, keeping the front flush with your tile backer board and screw it into the wall studs.
