Adding a bathroom to a house can be due to several reasons; traffic in the home or having a place to unwind from a busy day. A bathroom addition is, however, an investment, especially for a house on resell.
The total cost of adding a bathroom ranges from $3000 to $25000, depending on the features the bathroom will have. The average bathroom addition cost is $15000, but costs can go as high $70000 for a bathroom with luxurious features. The costs include materials and labor. Some of the labor will consist of plumbers, electricians, architects, and general contractors. An architect costs $90 per hour on average while a contractor, who oversees the bathroom addition, is paid averagely 7% of the total budget. Total labor costs for adding a bathroom will range from $1200 to $5,500, depending on the amount of work needed. For example, adding a bathroom when plumbing is in place relieves the homeowner of plumbing charges, thus reducing the overall addition costs.
Items to be included in the bathroom addition costs include bathroom tiles, a sink, bathtub, shower, bathroom cabinets, pipes, toilet, faucet, and countertops. The total bathroom addition costs also include the installation of each of the materials.
There are several determinants to the total cost a person can incur in adding a bathroom. Adding a bathroom to an already existing space is cheaper compared to adding the bathroom in a new space. Building a new bathroom is more expensive due to additional costs such as building permits which averagely costs $900. A bathroom added to a new space costs around $22000 to $35000, while one added to an already existing space costs $15000 on average. A bathroom can also be added in the basement in case the space in the house is not enough. The cost of adding a bathroom to the basement ranges from $10000 to $15000.
The type of material of items used in bathroom addition, as well as the installation cost of each item, largely contributes to the total bathroom addition costs.
1. Installation costs of pipes
Pipes are the first additions made since water is essential in the bathroom. Pipe installation costs will depend on the bathroom size and piping materials. The costs can be from $800 for smaller bathrooms to $4000 for larger ones. Piping costs can be minimized by adding a bathroom adjacent to an already existing bathroom in the house. Since piping occurs behind walls, pipes in the wall can serve the two bathrooms sharing the wall.
The type of floor in a bathroom needs a keen selection because it can cause accidents when it gets wet. Prices of floor materials vary. Tiles are the most popular bathroom floor costing $7 per square foot. On average, tiles for the entire bathroom cost $1600. Marble floors are the most expensive, costing $17 per square feet. Linoleum is the cheapest costing $4 per square feet, but it is not long-lasting. Ceramic, vinyl, and porcelain are relatively affordable, ranging from $5 to $15 and also durable. Installation costs of a bathroom floor can be as low as $1500 to as high as $4000.
3. Installation of bathtubs
Although not essential, bathtubs are an addition many homeowners want when adding a bathroom. Installation of the tub can range from $1000 to $5000. The price of a bathtub varies depending on the material of the tub. Bathtubs made of fiberglass and steel are the most affordable, with the price ranging from $300 to $500. The most expensive bathtubs are made of marble costing $1700 to $2500. Acrylic bathtubs are relatively affordable, with prices of $600 to $900. The fixtures and installation costs can be as high as $15000 for a jetted tub. The installation of a bathtub combined with a shower usually costs less than having the two installed separately.
4. Installation of the shower
Installing showers costs roughly the same amount as installing a bathtub. The installation cost is between $500 for regular showers and $10,000 for showers with glass or frameless doors. The costs of adding the shower will depend on the cost of shower inserts, pans, showerheads, type of door, and tiling. A shower with frameless doors is the most expensive addition, while one with stall doors or shower curtains the most affordable. Total addition costs of a small and simple shower with showerheads, a shower curtain and rod, walls, a shower valve, and safety railing can be as low as $290.
5. Sink installation
Installation costs of a sink are among the smaller costs that a homeowner can incur during bathroom addition. The highest installation cost is $600 but can be as low as $250, without the costs of sinks included. Luxurious sinks such as carved stone can, however, cause the installation costs to be as high as $5000. The cost of a sink also depends on its material. The most expensive is the fireclay sink, while the acrylic sink is cheapest.
6. Installation of the toilet
Toilets are essential in every bathroom. The cost of buying a toilet ranges from $100 to $200, while the cost of installing the toilet ranges from $125 to $230.
7. Installation of cabinets
The cost of adding cabinets to a bathroom will depend on the number and cost of the cabinets. A store cabinet costs $500 on average. Depending on the number of cabinets a homeowner needs, the total cost of cabinets can be as high as $3000, without installation cost. Installation costs of cabinets can be $4000 depending on the number of cabinets installed.
8. Installation of countertops
Countertops cost $2000 to $5000 to install. The exact price is determined by the type of material of the countertop. Stone, granite, and quartz are the most common countertop materials.
9. Installation of towel racks and mirrors
The cheapest addition to a bathroom is a towel rack. Towel racks cost averagely $60 to install. Mirrors can be installed as part of the cabinet or on their own. If installed as part of the cabinet, no costs are incurred. However, installing mirrors separately ranges from $60 to $300.
10. Lighting and fans
Installing lights in a new bathroom cost $500 on average. Each light is fixed at $150 to $500, implying that the total installation cost will depend on the number of lights the homeowner needs. Installing exhaust fans costs $250 to $500.
11. Faucet installation
Faucet installation ranges from $150 to $300.
There are two questions that homeowners may face related to bathroom addition and the costs incurred.
1. What are the factors to consider when adding a bathroom to an existing space?
There are three main factors that a homeowner needs to consider when adding a bathroom: location, ventilation, plumbing, and electricity. All these factors will also determine the total cost of adding a bathroom.
Plumbing and electricity can either increase or lower bathroom addition costs to a homeowner. When connected to an existing plumbing or electrical system, plumbing and electricity in the new bathroom will cost less. A strategic place for the new bathroom would be near the existing plumbing so that pipes can be directly attached to the plumbing system. Adding a bathroom in a room far from the existing electrical and plumbing system will include revamping the landscape of the home, which adds to the total costs incurred.
The location to add a new bathroom can be anywhere; the basement, an expandable closet, a spare bedroom, or anywhere accessible from the house that is attached to the garage. For homeowners that can spend more on bathroom addition, the bathroom can be built in a new space by demolishing a house wall.
Ventilation is also an important factor when adding a bathroom. Building codes require that every bathroom has a ventilation system such as a window or exhaust fan. Windows are enough for a bathroom on upper levels; lower level bathrooms may need both windows and exhaust fans.
2. Is remodeling a bathroom cheaper than adding a bathroom?
Remodeling a bathroom is, in most cases, the most affordable option for a homeowner looking to save. Bathroom remodels cost $8000 on average while bathroom addition costs $15000. However, for a homeowner intending to sell the house, adding a bathroom is the most economical option. Full bathrooms add the value of a home by about 20%, while half bathrooms add the value of the house by 10%. Once the house sells, there is a guarantee the homeowner will return money invested in the added bathroom.
Remodeling a bathroom is cheaper because no plumbing, electrical connections, and ventilating systems are required. Additionally, remodels aim at fixing or changing particular things in the bathroom. A homeowner may, for instance, decide to change the handles to faucets and sinks instead of replacing the entire sink or faucet. During remodeling, few items need to be purchased. Items like cabinets can be painted or refaced instead of buying new ones. Bathtubs, too, can be refinished, dismissing the need for purchasing others. In most cases, only floors require complete renovation because some floor materials like linoleum are not long-lasting.
Remodeling also has a better impact on the environment compared to adding a bathroom. Remodeling can involve updating the plumbing system to minimize water wastage; the use of less water is generally good for the environment.
