    Doing a tile surround with 4X4 tiles. Do I use 1/16 spacers or 1/8 spacers ?

    Thinset or tile mastic ? Over 1/2 inch hardibacker

    1/16, and thinset would be the best route. is a great source of info on tile work.

    Not all tile are created equal...if your tile are not very consistant (gauged), they can vary in size from one to another. A 1/16" spacing is tough to keep the grout lines straight - a larger one may be needed. 1/8" gives a little more leeway. Some wall tile have a built-in nub to set the gap, and no spacers are needed.

    If the tub is also used as a shower, use real thinset - the stuff you mix with water; never use mastic (even if it is labeled thinset!). Mastic, if it stays damp, will turn mushy. Thinset, being cement, gets hard and stays that way. Real thinset is usually cheaper, too, sometimes by a bunch. Caulk wherever there is a change in materials or a plane change (i.e., corners, and at the tub/tile junction), do not grout those junctions. is a great place to get tiling help.
