If you paint the room yourself, you will spend from about £16 to £65 on paint, according to Cost Helper. Other supplies such as paint brushes, rollers, primer and drop clothes will cost from £6 to £32. The total cost of painting a room will range from £22 to £97, depending on paint quality and supplies needed.
Hire a Painter
If you hire a painter, you will pay more to paint an 11 foot by 13 foot room. The Cost Helper website estimates that the cost to have one room painted will range from £130 to £260.
Painting an 11 foot by 13 foot room will require two gallons of paint. Painting yourself will be cheaper, but hiring a professional may lead to a better end result. If your budget allows, you may want to hire a painter for peace of mind.
