Hi,

We have a 3 sided 5.5 ft gas fireplace and we are created a boxed hearth on three sides to sit on etc. We picked a 1/4" porcelian slab that is 127" x 64".

The hearth (box) is 10'1" long and 30" deep and the height of the watterfall on the three sides is about 18"

I was asking for a no seam box - he says that, that will be heavy and brittle to transport so they have to miter the 3 watterfall sides on-site and not in the shop.

He suggests a seam so they can mitter the waterfall at the shop and just glue the seam on site which will be on the top and front waterfall.

The fabricator says that a mittered edge finished at the shop will look better than one finished onsite.

Not sure how bad a mittered edge will be if done on site vs at the shop.

So do I seam or no seam and have him miter on-site?

Thanks
