I am looking for a 5' to 6' white integrated counter sink with rectangular sink or square. Kohler only makes up to 48" and it is a porcelain one piece counter sink.

I've seen them made out of porcelain, acrylic resin, solid surface material.

i can find a 5 ft but it has 2 sinks and I do not need 2 sinks i need more counter. Where can I find or special order. I really like the "no grout" appeal and looks sleek.

thank you.
