That’s why we’ve discussed multiple options in every aspect of the bathroom. There’s a lot to consider after all. 

Addition of a Bathroom In the Basement: Complete Analysis

Building a bathroom in a space that already exists is nothing new. For growing families, adding a bathroom becomes a necessity. Other than that, it’s occasionally done to increase house value. 

But remember that, you will not be recovering what you invest. At least not completely. You’ll likely recover 70% to 80% of your investment during the time you sell the house. 

Remember this as you start making plans for your house. If you want to stay for a long time, go ahead. Otherwise, you have to be really smart when making the budget.

Fortunately, this project is similar to planning the cost to remodel a kitchen. If you have remodeled a kitchen before, this is going to be easy. If not, just go through the details explained below along with us.

Rough-In Plumbing

Every project requires a sketch to make sure everything goes accordingly. This sketching also has a separate that must be paid to the plumbers. 

Rough-in plumbing involves all the layouts, fixtures, and everything else that’ll be installed. You can compare this with a blueprint. 

When it’s done, you won’t be able to make other changes. If you do, it’ll cost you more. Note that this rough-in often may require a permit from local authorities.

For this, you’ll need a professional plumber to do it. Most services do them when they inspect your house. Because it helps them estimate a total price for you.

You’re likely to spend about $320 to $600 for rough-in plumbing. A useful advice will be to check the local safety codes. That way you can avoid unwanted situations.

Piping 

After making a thoroughly laid-out plan, it’s time to place the pipes. This is actually the very first step of making the bathroom. 

Depending on the types of pipe, the pricing of this section will vary. There are many options to use. For example, you could use PEX pipes instead of copper pipes. You can also use lead pipes and polybutylene pipes as well. 

The average cost to pipe a single bathroom is around $1,500 to $2,500. But material-wise, the final price will vary. 

Piping material costs are counted by linear foot. They will mostly cost about $1500. 

For your convenience, we’ve listed all the possible prices of different materials-

Pipe MaterialEstimated Price (Per Linear Foot)
PEX$0.40 to $0.50 
Copper$3 to $8
CPVC$0.60 to $0.80

As you can see, PEX or CPVC pipes cost way less than traditional copper pipes. Because of that most households use PEX and CPVC pipes instead. 

PEX Pipes

PEX pipes are the most used pipes nowadays. They’re flexible, easy to work, and super versatile. All of these qualities make this the first choice of many homeowners. 

To install PEX pipes you’re likely to pay $0.40 to $0.80 per linear foot. This is without any installation cost. With installation involved, the pricing will be around $1 to $4 per linear foot. 

Copper Pipes

The most traditional pipes of all homes; modern and old. Copper pipes are loved by homeowners due to their long-lasting durability. 

However, these pipes are priced super high and take a lot of money. Copper pipes cost 4X or 5X more than PEX pipes. Because of that, a good amount of people may not choose copper pipes. 

For copper pipes, expect to spend between $2 to $8 per linear foot. They may cost a lot but a good investment is a good investment, right? 

CPVC Pipes

These pipes are made of chlorinated polyvinyl chloride; hence the name. They are also made of plastic as PEX pipes. But they aren’t that flexible. 

Using these pipes in your bathroom will cost you about $0.60 to $0.80 per linear foot. These pipes will last for about 25 years without any problem. 

Toilets

Before installing a toilet, you have to choose a toilet. There are mainly two shapes of toilets; round and elongated. But there are many available options to pick from these two toilet shapes. 

If you’re trying to get a typical toilet, it’ll cost you around $200 to $500. But smart toilets can cost up to $8,000. 

There are many brands of toilets. They differ from brand to brand which can be hard to keep track of. But you can easily guess the price by flush type instead. 

Based on toilet flush types, here’s the picture you’re looking at-

Toilet TypeBudgetAverageTop-range
Upflush$600$900$1,300
Dual Flush$200$350$500
Compost Unit$600$800$1,200
Incinerating Toilet$3,200$6,000$9,000
Stainless Steel$1,100$1,500$2,500
Smart Toilets$2,000$5,000$8,000
Vacuum Flush$300$500$800
Wall-hung$150$600$1,200

From the chart, you can see the price range of these toilets. They differ a lot when it comes to prices. We’ve included everything from top to bottom. 

Upflush Toilet

These toilets can sit on any plumbing. They are cheap and are quite common in the USA. But they are quite pricey compared to regular toilets. 

To get the Upflush toilets, expect to pay between $600 to $1,300. 

Dual Flush Toilet

These are the most energy-efficient toilets. As the name suggests, there are two different flush modes. 

For liquid waste, it only flushes halfway instead of a complete flush. That’s how it can save water. These toilets can be managed for around $200 to $500.

Stainless Steel Toilets

These toilets are the entry point to premium toilets. They may not be too common for residential uses. But they’re still favorites of many homeowners.

Being extremely reliable and highly durable, they cost a lot of money. You can get stainless steel toilets for $1,100 to $2,500.  

Smart Toilets

Smart toilets have been getting recognition due to their useful features. They often come with bidets, sensors, and self-cleaning features. 

Getting one of these can make your experience premium for sure. These smart toilets start from the $2,000 range. Their prices gradually go up and reach up to $8,000 depending on features. 

Toilet Sink

Sinks are another essential that you need to install. Without this, your toilet will be incomplete. 

Average toilet sinks can be bought for about $300 to $600. But there are a lot of options to choose from as usual. Luxury sinks will cost you about $1,000 to $2,000.

Sink Material 

The price differences of sinks mainly depend on the material. The higher the material quality, the costlier it’ll be. 

For an acrylic sink, you’ll need to spend around $250 to $450. But a quartz sink will cost you between $400 to $700. 

For your convenience, we’ve listed the materials and their price range- 

Sink MaterialBudgetAverageLuxury
Acrylic$250$320$400
Stainless Steel$375$430$575
Solid$300$370$500
Cast Iron$400$550$700
Composite$400$500$700
Quartz$400$600$700
Fireclay$600$900$1,200
Granite$400$600$700
Copper $800$1,000$1,200

These are the prices it’ll likely cost you. Fireclay and copper sinks are considered top of the class. 

Unless you’re making something fancy, there’s no need to get them. A classic acrylic or granite sink should do the job. 

Toilet Faucets

Like toilet sinks, faucets can also enhance the overall look of your toilet. As usual, there are many options to choose from. 

The single-handle faucets cost significantly less. They cost around $150 to $250. But widespread faucets can cost around $300 to $1,050

Here, we’ve listed some faucet types and their price range for you-

Faucet TypeBudgetAverageLuxury
Widespread$300$700$1,050
Single-handle$150$200$250
Pull-down$250$350$550
Monoblock$150$200$250
Side-spray$150$200$350
Wall-mounted$300$800$1,050

For a good-looking bathroom, clean faucets are an absolute necessity. Even if you can’t manage a high-end faucet, you can still keep it pristine. 

Doing so will positively affect your bathroom. 

To save you some time, here we’ve listed some of our top picks-

Faucet 1
Faucet 2

It’s now super easy to choose from and instantly get started! 

Backsplash

Backsplashes are necessary to prevent the wall from being damaged. That’s why it’s only natural to want a backsplash in a washroom. 

But this option can be skipped if you want to. Because it’s not cheap to install a backsplash. Rather, the cost is pretty high. 

Like sinks and faucets, this also depends on the material. Based on that, the price range differs a lot. 

For your convenience, we’ve included some of the best materials used for the backsplash. Compare them all you want – 

Backsplash Material BudgetAverageHigh-end 
Wallpaper$110$150$250
Porcelain Tile$600$800$1,200
Mirror$540$600$700
Ceramic Tile$600$850$1,200
Glass $900$1,000$1,200
Aluminium $900$1,200$1,500
Stainless Steel$900$1,200$1,500
Marble$600$1,300$2,000

From the table, you can see that it involves a lot of money. But for the protection that it provides, it’s worth installing it. 

Bathtubs

If you’re installing a full-sized bathroom, you have to consider adding a bathtub. Without a bathtub, your bathroom is incomplete. 

Bathtubs have their own installation cost. They are usually included in the total labor cost. For now, we’ll only talk about the cost of getting a bathtub. 

Like sinks and faucets, bathtubs also have a lot of variants. But one thing that you need to remember particularly. It’s the size of the bathtub. Depending on size, the price will go higher or lower. 

The average bathtub can cost you around $650 to $5,000. But some fancy bathtubs will cost you around $10,000 and more. 

But material-wise, these are what you’re looking at- 

Bathtub MaterialBudgetAverageTop-range
Soaking $600$3,000$10,000
Free Standing$750$4,000$12,000
Walk-In$2,000$4,500$8,000
Clawfoot$600$5,000$10,000
Jet $1,000$5,000$13,000

As you can see the prices of the top range are really high. But there are good entry range bathtubs that can last for a long time. 

Don’t feel pressured and settle for a bathtub you can afford. But if you’re building anything fancy, choose the one that goes with the scheme. 

Showerheads

A good-looking bathroom requires a good-looking shower. That’s why we’ve included this particularly. 

Showerheads come in different types and sizes. Based on that, the price varies from model to model. But a typical showerhead can be managed for a mere $20

But if you’re looking for something fancy, expect to spend around $200 to $300. 

Fortunately, installing showerhead necks is super easy when the lines are installed. Because of that, this part doesn’t require any labor. 

Sewage Ejector System

You may not be familiar with this system. But that’s absolutely fine. This particular device is important for basement bathrooms. 

It’s because the basement is already below the ground. They can also be far from other pipes. Because of that, bathrooms require an ejector system. They push the waste out of your system. 

An average sewage ejector system can cost you around $450 to $1,500. 

Remember that, a lot of basement bathrooms require this. That’s why make sure to have it within your budget. 

Counter Replacement

Countertops are one of the most important parts of the washroom. Having a great countertop adds a very sleek finish. 

The average size of a bathroom countertop is 30 square feet. But if your counter is bigger or smaller, the cost will be higher or lower.

To save you some time, we’ve picked 30 as the standard size. Based on that, we’ve made you a small table- 

CountertopBudgetAverageHigh-end
Laminate$600$1,200$1,800
Stainless Steel$1,500$4,000$7,500
Quartz$1,200$1,800$3,000
Porcelain$1,650$2,200$3,600
Slate $1,500$3,500$6,000
Marble$2,100$4,000$6,900
Concrete$1,650$3,000$5,250
Soapstone $2,100$2,600$3,600
Granite$2,100$4,500$6,900

These are the costs that you’re looking at for a 30 square feet of counter. If you’re building a regular counter, it should cost you less. 

Doors

For a door you don’t need to spend much. Unless you’re building something fancy.

An average door can cost you around $100 to $500. For a door, be sure to pick solid wood to ensure better sound absorption. 

For the most sound absorption, you have to pick the solid core doors. These doors also have glue and foam which makes them the best for bathrooms. 

For a clearer picture, we’ve included this chart- 

Door TypeBudgetAverageTop-range
Hollow Core$30$200$400
Solid Core$100$300$500

The pricing will also differ based on size. But for now, these are the most accurate prices you can get. 

Speaking of doors, we’ve listed our favorite picks- 

Door 1
Door 2

You can now choose whichever you like and get started! 

Cabinets 

Cabinet installation costs can be hefty sometimes. But fortunately, bathroom cabinets are small compared to kitchen cabinets. 

The cost differs from material to material as expected. Wooden cabinets are the most used in a bathroom. Wooden cabinets can cost around $100 to $300 per linear foot. 

But for steel cabinets, it’ll be $1,000 to $1,500 per linear foot. 

To make it easier for you, we’ve made a small table for you- 

Cabinet MaterialEstimated Price (per linear foot)
Plywood $100 – $300
Hardwood $150 – $600
Steel$1,000 – $1,500
Acrylic$5,000 – $20,000 (per cabinet) 

Basic two-door cabinets will cost you around $100 to $200. But the mid-range cabinets can cost around $1,000

On the other hand, high-end luxury cabinets are priced at around $4,000

Electricity

If the basement doesn’t have any circuit boards or outlets, you have to wire it. Wiring costs are usually half of the total cost to rewire. 

Basic electrification costs around $450. Under that budget, you’ll be able to install the outlets and all sorts of appliances. On the contrary, high-end wiring may cost up to $850.

For this job, you’ll need to hire a skilled electrician. 

Painting

To finish a bathroom, you’ll need to paint it. If you’re tiling, the cost will be less. 

Painting a bathroom doesn’t cost that much. Rather, it only takes 1-2 hours to finish a bathroom. Painting cost is usually counted by total hours. 

A skilled painter can often charge around $40 to $100 per hour. But some services can ask you around $3 to $5 per square foot for painting. 

For your convenience, we’ve added a model cost for painting-

Coverage AreaPainting Cost ($2 per sq. ft.)Painting Cost  ($3 per sq. ft.)Painting Cost ($5 per sq. ft.)
100 sq. ft. $200$300$500
200 sq. ft.$400$600$1,000
400 sq. ft.$800$1,200$2,000

The painters will check the total coverage area first. This means the total area that will be painted. After that, they’ll give you the estimate. 

Flooring

Like painting, flooring is also important to have a clean finish. Bathroom floors can be made of different materials. Based on that, the final prices may vary. 

Average flooring will cost you around $300 to $3,200. There are mainly 4 types of flooring that you can install. They are vinyl, tiles, cork, and hardwood. 

To save you time, we’ve made you a small list-

Floor MaterialBudgetAverageLuxury
Vinyl$300$600$1,000
Plywood$1,400$2,000$3,200
Cork $900$1,200$1,500
Tile$500$1,500$2,500

Ensuring good flooring is super important. Make sure to have a good budget option for flooring.

Wall Tiles

Tiling the wall is also an option to ensure a great look. It can reduce the painting cost. But the overall cost will be higher. 

For tiling the wall, you’ll need to spend around $250 to $400. Within this price, you can tile all 4 walls of your bathroom. 

Bathroom Fans

Since it’s a basement bathroom, there won’t be any windows. This hampers the overall ventilation of the bathroom.

That’s why you’ll need to install a ventilation fan for the washroom. The average cost to install a ventilation fan is about $250 to $500. 

Mirrors

Bathroom mirrors are fairly cheaper to install. But there are fancy options available. 

The prices of the mirrors depend on whether they are attached or not. Some cabinets can let you attach them. Some don’t. For mirrors, you’ll have to spend between $50 to $250.
