The cost of a bathroom remodel varies depending on the size of the bathroom, the scope of the project and your choice of materials. Typically, a small bathroom or a half-bath could be remodeled for $5,000 or less. However, a full 5'x8' bathroom remodel can cost on average around $25,000 for all of the materials and labor. A master bathroom with double vanities, separate shower, tub and toilet areas can start around $30,000 and go up from there.
