The Overall Cost

Installing a basement bathroom, in general, will span somewhere between $3,000 and $25,000

The reasoning behind the considerable variation in price is whether the bathroom is an entirely new development or if you are renovating one already in existence.

Price of Installation

Realistically, the expense of the installment of fixtures and plumbing is between $2,025 and $2,925. This pricing will not include where the toilet placement is.

The number of new installations determines the costs (if you are plumbing a newly installed toilet and own a sink and faucet, the costs are relatively inexpensive). The estimated price for plumbing is around $600 to $1,600 per installation.

Labor Costs

The entire cost of labor for installing a bathroom is $1,200 to $5,500.

Hiring a licensed plumber costs $40 to $75 per hour. In an 8-hour work day, you can anticipate paying approximately $320 and $600.

Fittings and Fixtures

Generally, a bathroom installation comes with various fittings, fixtures, and features you can put in place. For instance, a structure of a sink and toilet can be kept relatively uncomplicated. An entire bathroom, shower, bath, and toilet installation can be more complex. The basement bathroom of your dreams can be completely custom-built.

The price involved in installing fixtures can vary since there is a great deal of variation in bathrooms. The layout of your bathroom can range from the most luxurious and superior materials to the most simple, traditional components.

Rough-In Plumbing

As the name implies, rough-in-plumbing is your plumbing layout depicted in a rough sketch. The project is intricate and may only be possible with a skilled specialist. Therefore, this cost is between $320 to $600. Approval by the municipality may be necessary before the commencement of work.

Inspecting local codes may be required as an initial step. On condition that they are not necessary, having a plumber plan the installation ahead of time can be advantageous, with no additional cost.


Cross-linked polyethylene (PEX) piping is a popular alternative to conventional copper pipes in basement bathroom installations.

PEX piping is a cross-linked polymer used as an alternative to traditional copper piping. Its benefit for a basement bathroom is that it does not require a local branch connection to the main pipe.

Flexible copper tubing connects a water supply to distant fixtures in homes, making it easier and less expensive to install bathroom facilities in remote areas of the house.

It takes about six hours to install PEX water supply lines. You can expect to pay between $1 and $4 per linear foot for PEX materials and installation labor.


The average price of a toilet is between $120 and $375. Pricing can increase by adding features such as a heated seat or a bidet.

Adding a toilet to your basement bathroom varies from $250 to $450, depending on the type of toilet and the amount of labor involved. This price range is unrelated to the piping installation price mentioned above; it will apply if you already have pre-piped plumbing and need to install a new toilet or replace an old one.

Skins and Faucets

You can choose sinks and faucets to add personality to a basement bathroom and express one’s specific style. Since there is a wide range of options available, it is advantageous to plan carefully before making your selections.

Personal preference means that the pricing varies greatly, although generally, you can expect to spend between $300 and $500 for a sink and faucet set.

Pricing for a sink and faucet set is highly variable, but on average, you can expect to spend between $300 and $500.

Sewage Ejector System

Sewage ejector systems, or septic pumps, are often necessary for basement bathroom plumbing since they are below ground level and frequently detach from the rest of the piping. Sewage ejector systems assist in extracting sewage from your system and do not only have relevance to waste products from a toilet but also a shower or laundry room. Approximately 85% of basement plumbing required this apparatus.

The expense of installing a sewage ejector pump can range between $800 and $1,450, depending on the labor and materials used.


Installing doors to your basement bathroom will range between $100 and $300, determined by whether a skilled expert does the installation labor for you.

Attaching a door with standard lockset hardware is relatively simple, but hiring a professional carpenter might be advisable if you need more energy to hang the door while you fit it (or if you have no one to help you).

Shower Heads

Shower heads come in various materials, designs, and prices. The cheapest shower heads are made of plastic, while the most expensive are brass and stone.

Installing a showerhead can cost you approximately $300 or more. The good news is that shower heads are reasonably simple to install, and hiring additional assistance is unnecessary.


The average price of a bathtub can vary greatly depending on whether it is installed or pre-fabricated. You can purchase pre-fabricated models from retailers for between $200 and $2,000, but installation will add significantly to the cost. Seniors who require walk-in tubs may find these considerably more expensive than standard ones.


You may be required to bring electricity down to your basement or install wiring for light fixtures, newly added outlets, and other electrical components. Electricians charge approximately $70-$80 per hour for this type of work, which may require a permit if you live in an area where the law requires special licensing. Ground-fault circuit interrupters (GFCIs) are recommended in all bathrooms to help reduce the risk of electrical shock.

Once your installation of core constituents of a basement bathroom is complete, there is no opportunity to decide whether or not you desire any extras. There is no absolute necessity for additional features, but individuals who have invested in a bathroom may find these accessory features advantageous.

The “extras” listed above have different prices, which is beneficial in measuring how large or small you would like your budget to be.
