6 worst home fixes for the money
Unless you're a hermit who never entertains, you've probably wished for an extra bathroom now and then.
But bathroom additions require serious coin. For a moderately outfitted addition with synthetic stone or plastic laminate surfaces, figure parting with about $21,695, according to the Remodeling report. Go upscale, with finishes like premium marble or fine tile, and you can easily spend in the neighborhood of $40,710.
Either way, you get about the same return: 53 cents on the dollar. "In the buyer's mind, the additional bathroom isn't worth that additional $20,000 to $40,000," Keim says.
Investigate a less-expensive way to get the same result without flushing quite as much cash. While additions usually cost more, pros might be able to reconfigure your existing space to add a bathroom for less, Alfano says.
