You can lower your budget with the use of the cheaper ABS piping instead of PVC. Check with your plumber to see if this is a viable option because it can cut costs dramatically. In addition to plumbing costs for a kitchen or bathroom, there are also costs associated with an electrician. Regardless of the addition, you are going to need electricity. Often, a new breaker must be run from the main panel in addition to the various boxes needed to deliver power to fans, outlets and light fixtures.
A square bale of hay is usually 2 feet wide, 4 feet long, and 2 feet tall. A round bale of hay varies, depending on the baling equipment. The dimensions usually range from 4 ft x 4 ft to 4 ft x 6 ft. Edit: There are three sizes of square bales, small medium and large. Small bales are 2'x2'x4'.
A small square bale weighs from 40 to 100 pounds and large square bales weigh from 140 to 2000 pounds depending on how they were baled. So a 700 pound round bale could contain 17.5 small 40 pound bales or 5 of the 140 lb large squares. A 2000 lb round bale could contain 50 of the small 40 lb bales, 14.3 of the 140 lb bales, or one of the 2000 lb bales. Comparing volumes of hay will give similarly large ranges.
