Just heard back from Racetrack. Here is their cost estimate for a 12x24 garage:
Floor plan specs:
FLOOR SIZE: 12' x 24' Rectangle
TILE TOTAL: 288
110 - Royal Blue Diamond Tile(s)
110 - White Diamond Tile(s)
68 - Black Diamond Tile(s)
288 x $3.49 = $1005.12 plus shipping and edges
We recommend installing ramp edges at the opening of your garage door. Do you know the width of your door?
I guestimated it at 10- feet and they gave me the pricing for the edging and shipping as an extra.
In total, the bill will come to $1120.02 including shipping.
