To estimate the cost of a bathroom remodel, a homeowner needs to consider factors such as the bathroom's shape or layout, square footage, the number of fixture upgrades, labor and supplies, notes Homewyse.com. Additionally, a breakdown of the remodeling costs can also include modification of existing plumbing and electrical systems and the addition of windows, walls or a different ceiling. Typically, as of 2015, remodeling an existing 40-square-foot bathroom to one that is 120 square feet costs on average about $29,950, states Fixr.com.
Remodeling an existing bathroom to encompass a larger space is a complex project that can require the services of a carpenter, electrician, plumber and painter. Additionally, the cost also can include fixture upgrades, new faucets, relocation and replacement of the shower stall and toilet, installation of ceramic tiles and lighting, adding a window, repairing a ceiling or wall and adding cabinetry, according to Fixr.com. Although $29,950 is about the average cost of a remodel for this project type, another factor that can either decrease or increase this estimated cost is the region of the country where the home is located.
As of 2015, to make improvements to basic essentials in a small- or medium-sized bathroom, the average cost is approximately $9,250, as noted by HomeAdvisor.com. This website has a chart showing the cost breakdown of adding different options to a bathroom. The chart provides price ranges from low to high for different options such as tubs, flooring and lighting.
The general rule is that the budget for the project should be no more than 5 to 10 percent of the home's value. Once the budget is determined, the National Kitchen & Bath Association recommends the following breakdown for the project.
- Labor: 20 percent
- Cabinetry and hardware: 16 percent
- Fixtures: 15 percent
- Faucets and plumbing: 14 percent
- Countertop: seven percent
- Floor: nine percent
- Doors and windows: four percent
- Walls and ceiling: five percent
- Lighting and ventilation: five percent
- Design fees: four percent
- Other: one percent
The prices of the fixtures themselves can make estimating the cost of remodeling a home a bit tricky, as the cost can vary greatly depending on the model. For example, the cost of installing a bathtub alone can cost around $400 to $1,500 with low-end brands, $2,600 to $4,100 for mid-range brands and $6,000 to $8,000 for high-end brands.
