Materials and Tools List


  • A circular saw with three blades: general purpose wood, metal ($5) and diamond masonry ($20). The diamond masonry blade costs more, but last longer and cuts quickly.
  • A hammer
  • 2'-3' level. A long level is worth is it. You can find a long, inexpensive aluminum level at Home Depot if you do not already have one.
  • Grinder (optional). You can use the grinder to cut rebar, wire, and concrete block. You can buy an inexpensive grinder for about $25, which will save you time from not having to change blades on your circular saw.
  • A chalk line ( <$10).
  • A 1/4" x 1/4" notched tile trowel for the
    mortar base.
  • Goggles and a dust mask
  • A mixing tub (<$15)
  • A hoe for mixing ($10 for a cheap one, $20 for a good one)
  • A square edged transfer shovel ($20).
  • A Tamper ($20 or build one from a square of plywood and a 2x4).
  • Concrete mixer (optional). Rent one from Home Depot.
  • Tile saw (optional). You can get by with a diamond blade and a circular saw. If you have complicated tile, brick or stone trim or finish, you can either rent a tile saw, or purchase a small, but functional tile saw from Home Depot for less than $100.
  • Ratchetting cargo straps (optional). About $10 at WalMart. Used to hold the hearth form in place while it is curing.
