BEST PRACTICE: To achieve the best results, we

2 feet outside of the showering area.

On top of existing subfloor and walls install cement
backerboard in preparation for tiling. Make sure
that the top of the backerboard is roughly 1/8”
higher than the Fusion pan. Start with a bed of
thinset using a 1/4” notched trowel. Next, attach
the first layer of 1/2” backerboard with 1 1/4” cement
board screws 8” on center. Then, making sure to
stagger the joints, attach the second
layer of 1/2”
backerboard with 1 5/8” cement board screws 8” on
center. Finally, finish the joints with alkali-resistant
mesh tape.

Check that the Fusion Pan is level on all four sides.
Fill in any gaps around the perimeter of the pan over
1/8” with latex or acrylic caulk.
