Cheapest way to make an economy hearth

[JPapiPE]

I have an Englander 13NC on order and need to make an economy hearth ( specs say a 48"X48" hearth is required)
What is the cheapest way to go? I have seen the prefab hearths on sale but $400 is not in my budget.

As Be Green once said:

"If no alternative, metal studs + dead air space + 2 layers of durock should get you there. DonCT made his hearth this way.
