Make final adjustments before driving it home—you only get
one shot at placement. Once the foam tape touches the wall,
On new tile walls, the correct way to install a ceramic
corner shelf is to set it directly into the thin-set mortar
during tile installation. But you can add a corner shelf
(or another soap dish) on existing tile.
Stop by a tile shop and pick up a “flat-back” corner
shelf unit (about $20). Then buy soap scum remover,
double-face foam tape and a tube of silicone caulk. Clean
off all the soap scum or the bond might fail.
Apply a strip of foam tape on each mounting flange,
stopping 1 in. short of the ends. Test-fit the shelf before
you remove the wax liner paper from the tape. Shim any
gaps with additional layers of foam tape. Once the shelf
fits squarely into the corner, apply the silicone caulk
Locate a spot in the middle of a row of tiles (no horizontal
grout lines running through the caulk). Then
remove the liner, square up the shelf and press it against
the tile (Photo 2). Once the tape grabs, let go, wipe off the
excess caulk and then tool the joint with a damp fingertip.
If you blow the placement, you’ll have to muscle off
the shelf, completely clean off the back and reapply fresh tape, so be careful.
