I bought the following items when I was going to convert our old builder grade tub/shower bathroom to a walk-in shower. I finished the demo of the old bathroom then had some health issues that led me to hire someone else to do the job who didn't wind up using the Kerdi system. If you were to buy each of these items at Floor and Decor today you would pay a little over $1,000 plus tax. I'm willing to let it all go for $650. I'm located in DFW.

Shower Kit without drain, offset drain location 38" x 60"
Shower Bench 11.5"d x 28"w x 20"h
Shower Niche 12" x 28"
Drain Flange with seals
Brushed Stainless Steel floral drain grate

If in good shape might be able to return some things to Lowes/HD for store credit if they carry the same thing. Even if you didn't buy it there.
