Because of cohesion and transpiration, water is able to move against the flow of gravity in plants. The attraction of water to other water molecules, or cohesion, allows water to pull other water molecules up through the xylem.
Room addition cost about $210 per sq.foot and if there is a bathroom in addition you should add $5,000 in average and if there is a kitchen in addition you should add $10,000 in average to total price of $210 per sq.foot x sq. footage.
(40sqft). Cost on adding a bathroom depends if you have an existing room or if you will be adding a new roof to cover the new room. The latter is the most expensive as you will have framing costs (and permits and blueprints,etc) and could cost $10-$15k.an anyone give me a cost estimate to add a bathroom and 250-300 sq ft addition... I'm looking for a general cost to add a bathroom and about 250-300 sq ft. The bathroom would be a 3 piece-toilet, stand up shower (tiled w/glass doors) and double vanity.
