The more luxurious the materials for a bathroom remodeling project, the higher your budget will be. Using marble for your counters, custom cabinetry or handpainted ceramic tiles for your new shower walls in the master bathroom will look terrific. But it will also raise your material costs considerably more than installing a laminate countertop and low-end or mid-range tiles.
For a small bathroom of roughly 100 square feet, labor costs could run an average of $12,000 or $13,000 on the high end. This would include the labor to completely redo tile, completely install new fixtures, complete any necessary wiring and plumbing, and have everything inspected afterward. Never overlook the importance of having your wiring and plumbing inspected directly after the contractors finish. This can end up saving you a lot of money on repairs in the long run.
The cost of your project will be tied to a number of factors including the room size and the quality of materials including the grade of fixtures, cabinets and finishes. Bathroom vanities often eat up the majority of the materials budget. Whether a change to the floorplan is involved will also determine the ultimate cost of your master bath remodel.
