A 20yd dumpster is 21’L x 8’W x 4’H. It is roughly the equivalent of (7) full-size pick-up truck loads. Twenty yard dumpsters are great for medium-size clean-outs (4-5 rooms) with a few larger furniture pieces. It will also work for most complete kitchen renovations. The cost for a 20yd dumpster rental generally ranges between $500.00 and $650.00; depending on the county and the waste-type. The rental is normally for up to (10) days.
