I am making a small bench for a recently remodeled bathroom . I have designed
it to use two left over porcelain floor (11 3/8" x 11 3/8") tiles on the top.

The top is rabbited to accept the tiles and provide direct support from the
frame. I have attached a backer board to the bottom to give full support to the
tiles.

The question is: what adhesive should I consider using. I have a lot of regular
tile adhesive left over from the walls. Would that be the right thing to float
into the prepared cavity, or should I be looking at something else?

I plan on using clear silicone to seal around the edges. The tiles do not
directly abut each other.

As always, TIA.
