Cost To Build A Bathroom From Scratch

It is one of the most exciting projects that you can do on your own. The process starts with planning the size and shape of your new bathroom. You should also plan where you want to place the toilet, sink, and shower. You should also consider which wall will be used for storage and what type of materials you may want to use for walls and floors.

After you have made these decisions, it is time for construction. If this is your first time building a bathroom from scratch, then it can be quite intimidating. However, there are many different ways that you can build a bathroom from scratch and all of them are simple enough for anyone who has some DIY skills and knowledge of construction techniques. One way to build your own bathroom from scratch is by using pre-made kits from companies like Home Depot or Lowe’s; however, these kits may not always be available in the size or color that best suits your needs. Another option would be to hire an architect who specializes in designing custom homes; however, this option will cost more money than using pre-made kits available at big box retailers such as Home Depot or Lowe’s (which are usually priced under $100).

When you’re building a new bathroom, there are many things to take into consideration. Not only do you need to hire an experienced contractor or do-it-yourselfer, but the cost of materials is also key. And if you have an existing bathroom that needs work or remodeling, it’s possible that the cost would be even higher than starting from scratch. In this article we’ll go over what makes up a complete bathroom renovation and how much it costs on average.


Framing is a major part of the construction process. It’s also one of the most expensive parts of building a bathroom from scratch, so make sure you know exactly what you’re getting into before investing in framing materials. If you choose to do it yourself, you’ll need access to power tools and other specialized equipment if you want to avoid headaches later on in the project (and who wouldn’t?).

If you don’t have any experience with carpentry or home improvement projects, we recommend hiring a contractor for this step since they’ll be able to handle all aspects of your framing needs. You can expect them

to charge anywhere from $2,000-$5,000 for this service depending on how much space needs framing out as well as whether or not there are any issues with existing walls that need fixing first before installing new ones.


When designing a bathroom, ventilation is a must. The purpose of ventilation is to remove moisture and odors from a room, which can be achieved by using windows, fans, or vents.

The best choice for your new bathroom will depend on the size of your space and what sort of style you’re going for. For example, in small spaces with no windows (or ones that face an unpleasant view), it may be more practical to install an exhaust fan instead of opening up walls to create a window.

Smaller bathrooms usually require less natural light than larger ones do—and this often makes them feel cramped and claustrophobic if they don’t have sufficient indoor lighting options available on their own terms–but this doesn’t mean that they should lack sunlight altogether. In fact there are several ways we can incorporate open air into small spaces like bathrooms without sacrificing functionality or comfortability:


Plumbing is a major expense that can add up quickly. If you’re looking to save money, consider doing some of the plumbing yourself. While this may sound like a lot of work, there are plenty of tutorials online that will walk you through how to install your own pipes and fixtures. And if you don’t want to do it yourself, there are also many affordable plumbers in your area who can help out with smaller projects such as installing sinks or toilets.


Electrical work is more expensive than plumbing and drywall work for a few reasons.

  • Electrical work is more complicated
  • Electrical work requires a permit
  • Electrical work requires specialized tools and training

Drywall and Insulation

While drywall can be installed by a professional or by the homeowner, it is relatively inexpensive and easy to install. However, labor costs may drive up the cost if you choose to hire someone to do it for you.

In addition to drywall, insulation should be installed in your bathroom walls before any other materials are added. This will help keep sound from traveling through your home as well as prevent heat loss in cold climates and heat gain in warm ones.

Painting and Decorating

You will need to decide on the type of paint you want to use, whether it is latex or oil-based. There are different types of primer that you can use; some are meant for oil-based paints while others are designed specifically for latex.

You can also opt for painting the walls and ceiling first, then the trimwork and finally the flooring. You will want to use a roller or brush depending on what has already been done in your bathroom renovation project.

Most people choose not to paint their floors because they think it’s too much work but if you follow these steps below then this task can be quite easy:

Tile Installation

Tile installation can be done by yourself or a professional, but it’s really not worth DIYing unless you have the right tools. If you plan on installing tile in your bathroom, here are some things to consider:

  • Tile installation costs can range from $1.50 to $3 per square foot depending on the material and project size.
  • Tile is easy to install, but it does tend to get messy (you’re working with water). If you’re worried about getting wet when tiling over spare parts of your floor or wall, plan on having some old towels ready when your tile guy arrives at your house.
  • You may want to hire a professional if they don’t have the right tools or experience installing tile in bathrooms—especially if they’ve never done it before.

Vanities, Mirrors, and Lighting

A vanity is the countertop piece that sits underneath your sink. It can be made of a variety of materials and finishes, including stone, wood, glass and metal. The cost of a vanity varies widely depending on its material and style; however, you can expect to pay between $300 and $1,000 for an average-sized white bathroom vanity.

vanity: $300 – $1,000

mirror: $50 – 500

lighting: 200 – 2000

Remodel Vs New

If you’re looking to remodel a bathroom, there are a few reasons why it might be cheaper than building a new one from scratch.

  • Remodels require less demolition: If you’re just replacing the tub or adding more square footage to your bathroom, then you won’t need to tear down any walls or floors. This means less wasted materials and labor costs.
  • Remodel is more efficient and green: Since the structure is already in place, efficiency is maximized when it comes time for remodeling. This can save energy and money on heating/cooling bills during construction. Additionally, using eco-friendly products will make your home even more sustainable after construction has been completed.

Average Bathroom Size

The average size of a bathroom is 8.5×6.5 feet, with a toilet, sink and shower/tub combination taking up the most space. According to Remodeling, the average cost of remodeling an existing bathroom is $6,500 (including appliances). The average cost of building a new one from scratch ranges from $30,000 for a basic design with no upgrades to $225 per square foot for luxurious fixtures and finishes; this would represent a total investment ranging from $28k to over $200k depending on your choice of materials and features. If you want a tub in addition to your shower stall or stand-alone bathtub: add approximately 25% more money than if you don’t need one.

Bathroom Flooring Cost

Bathroom flooring prices vary widely, depending on a number of factors. For example, tile costs more than vinyl and laminate because it’s more durable and beautiful. It’s also difficult to install yourself—but if you’re going for the look, you might want to consider hiring an expert.

Hardwood floors are usually only used as decorative accents in bathrooms. They’re not absorbent enough for use with showers or tubs, which makes them vulnerable to water damage over time. That said, they do make great rugs.

Carpet is another popular choice for bathroom floors because it’s soft underfoot and absorbs sound well. If you have pets or kids who tend to track in dirt when they get home from school or daycare, carpeting may be your best bet since it can be cleaned easily—and again: it’ll keep those feet warm.

Shower Cost

The cost to install a shower will vary based on the size of your bathroom and what type of shower you choose. A basic, standard shower can range from $500 to $1,500; however, an all-inclusive spa-like model could cost more than $3,000.

Tub Cost

Tubs are one of the most expensive parts of a bathroom. Most tubs are made from acrylic, fiberglass, or cast iron and can range in price depending on their size and style. The average cost for a tub is $1,000 to $2,000.

Toilet Cost

If you’re looking to replace the toilet in your home, the cost of a new unit can vary depending on where you live, the type of toilet you choose (e.g., one-piece or two-piece), and whether or not it’s installed by a professional.

If you buy a high-end toilet from Kohler or Toto—you know, those high-end companies that produce things like expensive faucets and toilets?—you’re looking at spending $300 to $500 per unit. If you want something more mid-range from American Standard or Sloan Valve (or “Sloan Valve”), expect to pay between $200 and $400 for each new toilet in your home.

Needless to say, toilets are one of the most expensive parts of any bathroom remodel project because they’re so essential when it comes time for #2 business. But if this isn’t quite feasible right now due to budget constraints—or if there’s no way they’ll fit into any future budget plans either—you’ll have some options available that could save some money while still delivering great performance.

Sink and Vanity Cost

Sinks and vanities vary widely in cost. The most basic sink for a single bathroom is around $50-$75, but if you want something more luxurious or unique, you may have to pay up to $1,000. This cost can be even higher if your vanity has granite countertops or other high-end material. Some of the more expensive vanities are made from marble or quartzite and even feature sinks made out of these materials too.

Depending on what kind of sink or vanity style you choose, the price will vary quite a bit as well. If you want a simple white porcelain sink with no frills (or faucet), it’ll probably cost around $100-$200 depending on where you buy it from; however, if your looking for something more luxurious with fancy features like gold accents then expect to pay hundreds more than this amount.

Electrical and Lighting Cost

Electrical and lighting costs will vary greatly depending on the type of electrical, lighting, and other equipment you choose. Electrical work can include installing new outlets and switches or re-wiring an entire bathroom. Lighting fixtures could be simple task lights, recessed cans, or wall sconces.

Pre-made cabinets are expensive, so many homeowners opt for custom cabinetry that is designed specifically for their bathroom’s layout. The cost of custom cabinetry will vary depending on the materials used to build it, but here’s some general guidance:

  • Solid wood cabinets will cost more than particleboard or MDF (medium density fiberboard) due to higher quality materials and construction techniques required for solid wood construction—but they may last longer too.
  • If you have a small budget but want something durable enough to withstand years of use in a wet environment like a bathroom or kitchen then laminate is probably your best option since it doesn’t require painting or staining; just wipe down regularly with warm water & mild detergent when needed.

You can build a bathroom from scratch for $5,000 to $30,000

Your budget and the size of your bathroom will determine how much it costs to build a bathroom from scratch. The average cost to build a bathroom ranges anywhere from $5,000 to $30,000, though it can vary depending on what you need.

If you’re building a master-sized bathroom with dual sinks and separate vanities, for example, expect to spend between $20K and $25K. You’ll also want to factor in additional costs for materials like tiles or stone countertops if you plan on having them installed into your new space. Smaller bathrooms tend to be cheaper because they require less materials and labor—an entry-level master bath could run about $12K depending on its size and other factors like plumbing fixtures and fixtures such as tubs or showers (which are often included).

Even if money isn’t an issue when building a new home addition—or even if there is one but doesn’t have any impact on the final price tag—there are several things people can do before hiring contractors that help reduce construction costs even further:

At a minimum, you can expect bathroom construction costs to start at $1,100 for the smallest bathrooms, excluding labor.

At a minimum, you can expect bathroom construction costs to start at $1,100 for the smallest bathrooms, excluding labor. Labor is the biggest cost. At $15 an hour with two workers and a helper, you’re looking at roughly $3,000 worth of labor alone in your total budget. So if you plan on doing some of the work yourself (or hiring only one professional), this is where you can save money by making some cuts in other areas.

One way to do this is by buying materials in bulk instead of individually at full price—but this should not be done without careful consideration because it could end up costing more than just paying for everything up front. Another way is by finding used materials (like fixtures or cabinetry) from Craigslist or eBay—but again, this needs careful planning as well since it requires researching what types of materials are available and then determining whether or not they will fit into your design scheme before actually purchasing anything.


With all the different choices and costs that go into building a bathroom from scratch, it can be tough to know where to start. But don’t worry—we’ve got you covered. At this point, we’ve covered everything from framing through drywall installation and painting. The final step is installing tile flooring or carpeting before hanging up mirrors, vanities, and other decor items on your walls.
