Drawing or Dimensions of standard Gunite Spa

[markmac]

I'm doing up the cad drawings and I'm sure on the standard spa gunite dimensions. I see standard spa sizes of 7x7, but that is the outside. Does anyone know the standard thickness of the gunite for the spa walls? I assumed the top border was 12", as all the pics I find seem to have a thick top border with tiles. However I have also saw listings for 7x7 gunite spa with area of 40 sqft from PB's. That would suggest the gunite is ~8" in the spa.

If anyone has autocad templates of a standard spa, that would be awesome.

Thanks.

There is no such thing as a standard spa.

An engineer will specify wall thickness but bond beams are usually 12" thick
