I had solid sheets of granite installed for shower. Looks good except for the adjoining areas.
First shower does not run width of room - so there is a support wall for the right hand side of shower that run three feet. Problem with this is the that the granite and hardieboard backing goes from running exactly even at the bottom to about 1/4 inch over at the top of the wall cap.
On the other side (wall side) they shimmed out the HB to make it plumb. And the granite goes almost all the way to the edge of HB. So I am wondering how to make a smooth transition from HB/granite to drywall without much wiggle room.
Please do not advise to call granite contractors... They basically said oops... and gave a major discount. So they are done.
