I am trying to locate a 30" shower stall to replace and existing ceramic tile shower of the same size. Any idea's?

Have you tried your home stores Home depot,Lowe's .I think both can special order for you. I don't think that size is a stock item.Good luck

I use Swanstone (http://www.theswancorp.com/) exclusively. Great product at a fair price and easy for most home owners to install.

If you are in Canada, Home Hardware carries them.
