A 1,200 square foot basement remodel costs $30,230 on average, or $25 per square foot for materials and installation with most homeowners spending between $19,100 and $36,000.

Ultimately your basement remodeling can cost about 30% less than a refinish. The plumbing and electrical work is already in put, so if you don’t move any major plumbed or wired fixtures or walls and less paid labor is required.

The cost of a little basement remodel—changing flooring and moving one wall—can cost a few thousand, whereas a major remodel of adding another bathroom and bedroom or an entire downstairs apartment can cost tens of thousands.

Cost to Build a Basement

The cost to build a basement foundation and walls, along with installing adequate moisture prevention and drainage, for a 1,200-square-foot basement is about $25,000 to 28,000.

This is before any of the finishing-out work begins.

  1. A poured foundation is $4.63 per square foot or $5,560.
  2. Hot mop the basement walls for thermal and moisture protection for $2.73/SF or $3,280.
  3. Waterproofing system sheeting costs $3.50 – $6.50 per square foot or $6,000.
  4. Concrete walls with steel rebar are poured for $3.30 – $5.52 per square foot or $5,290, or ICF/EPS walls with concrete cost $8.12 per square foot or $9,740.
  5. A foundation investigation will cost an average of $2,280. A soil engineer will assess the soil-bearing worth to determine the drainage and grading needs and wall-bearing needs before pouring the foundation and walls.
  6. Installing interior and interior drain tiles to drain away any water that might pool near the foundation costs $2,500 – $5,000.

Cost to Add a Bathroom to a Basement

The average cost to add a bathroom to a basement is $7,600 or between a range from $2,500 to $12,400.

A basement bathroom addition can add 10% – 20% to the worth of your home. Drainage and plumbing will be your two most significant cost factors. For a little basement, a half-bath with no shower or tub is adequate, while a bedroom suite needs a full bathroom.

Pipes will own to be brought below, and a sewage pump and backwater valve might own to be installed to ensure proper drainage of effluent and bath/shower water if gravity doesn’t work in your favor. Take care to ensure moisture prevention with a dehumidifier and vented fan system. Numerous building codes own minimum dimensions regarding how shut each fixture can be to the next.


  1. Cracks in Walls and Joints – Waterproof the cracks, and cracks and gaps around pipes, by filling with hydraulic cement, which expands as it cures.
  2. Cracks Around Windows – Dig out a larger well space and fill it with gravel, so water drains away from the window. Install a window well cover, $30 – $85 for the cover. Caulk window for $1 – $3.70/SF.
  3. Cracks in the Foundation – Foundation repairs run from $500 to $15,000 if needed.

Shower or Bath Moisture

  1. Install a bathroom vent that sends humid air exterior.

    (Add $50 to $100 if water pipes are needed.)

  2. Adding a dehumidifier is $250.


  1. Light fixtures, shower lighting, sconces, ceiling lights $10–$4,500
  2. Mirror $12–$3,000
  3. Sink faucets $150–$750
  4. Showerheads, shower panels, and faucets $90–$10,000
  5. Towel bars, hooks, etc. $40–$160

Basement Refinishing Kits

Basement refinishing kits cost $50 to $70 per square foot and come with everything you need to finish out the basement—framing, moisture-repellant drywall, insulation, floor joists, and ceiling joists.

Some even include windows and flooring. The wall panels are removable and can lock in put easily.

Basement Waterproofing Cost

Basement waterproofing costs about $1,480 for simple crack filling with an average of $2,000 to $6,000 for drainage improvements. Costs range from a minimum of $250 up to $20,000. Most homeowners waterproof after they discover water in the basement from poor drainage around the foundation and walls. Waterproofing will be a lower cost if it’s included in a larger basement finishing project.

The main reasons for water or damp conditions in a basement, and the cost to repair them are:


  1. Up-flushing toilet – Connects to the upper floor’s sewer line.

    $400 – $1,300

  2. Sewage-ejector system – Has a little tank that holds effluent and wastewater temporarily but pumps waste to the main sewer line. $940 – $4,400 installed
  3. Pressure-assisted toilet – Gets rid of effluent with air pressure. $125 – $450
  4. Composting toilet – Turns effluent in the holding tank into compost for use outdoors.

    $200 – $1,100

Poor Soil Drainage

  • If any ground leveling is required to assist with redirecting water away from the home, that could add
    1. $11 per cubic yard to spread that soil in a diverse part of the yard
    2. A sump pump with the accompanying electrical work costs an average of $480 – $790 A sump pump without the electrical work costs $140 to $205 and $105 for installation.
    3. If the work is to be done by hand with a shovel, between $33 and $67 per cubic yard depending on the density of the soil when removing it
    4. Install a drain tile system to drain away any water that might pool near the foundation at the cost of $2,500 – $5,000.

      This involves digging a 2-foot space for gravel, drain tiles, and a basin so incoming water can be pumped away from the basement.

    5. Another $5.50 per cubic yard of ground to be moved by a backhoe operator with a minimum charge of $500
    6. A water-powered backup pump starts at around $200.


    Take care of some initial insulation in the basement by adding slip foam insulation on your cold-water pipes to prevent condensation from building up and then dripping inside your drywall or ceiling.

    Put slip foam on the hot-water pipes to prevent the loss of any heat. This should be done before boxing in any of the pipes in the basement. Tube pipe foam insulation costs approx. $1.50 – $3.70 per six-foot piece, which can range from ½” – 1” in thickness.

    Fan Vented to the Exterior

    1. $80 – 400 for the fan—a building code must-have
    2. $250 – $500 for installation

    Basement Refinishing

    The cost to refinish a basement will range between $22,000 to $46,000 for a 1,200-square-foot home or around $38 per square foot for most homeowners.

    Basement refinishing can be easier for significant changes because no demolition is required and the framing is open, so every electrical and plumbing work can be done first without any need to drill into or cut open drywall.


    1. Fiberglass and tub combination $1,070 – $1,180 installed
    2. Shower stall $823 – $1,720 installed


    1. Install drainage pipes inside the basement walls and own water pumped out by a sump pump. Install a second wall, so this new drainage system is enclosed between the ancient and new walls.
    2. Repair or install gutters with downspouts that direct water at least 10 feet away from the basement and foundation.
    3. Clearing debris from gutters and redirecting flow away from around basement is $300.
    1. Porous concrete walls — Waterproof your walls with masonry sealer, but this can only be painted on bare concrete.

      Any existing paint or efflorescence must be removed first.

      $0.61 – $0.87/SF to own it done. Five hundred gallons covers 500 square feet.

    Basement Demolition Costs

    Basement demolition costs for your existing walls and flooring ranges between $1,900 to $8,700 for 600 sqft, and between $3,400 to $11,900 or more for a 1,200 sqft basement. For a finish demolition of the existing walls, stripping back to the framing, and ripping up the existing flooring, you could be looking at an additional cost of between $2.70 – $10.10 per square foot.

    Depending on the extent of the remodeling to be done and the ease of access for the construction crew, your costs will vary.

    Basement HVAC System Cost

    The average cost to install an HVAC system in the basement is $4,000 to $6,400 with new ductwork costing an additional $1,500 to $3,000. You might not own to install a separate HVAC system for the basement if the existing unit upstairs can handle the additional workload.

    Diy unfinished basement ceiling ideas

    If it can’t, then either upgrade your existing unit or install a second unit downstairs. You’ll own to install new ductwork and ventilation either way, unless you install a mini-split system.

    HVAC Unit MBtu Average Cost
    2 Ton 71 Heating $4,050
    3 Ton 89 Heating $4,600
    5 Ton 107 Heating $6,400
    1. New Ductwork – On average, ductwork costs $24 to $38 per linear foot to install in walls.

      Add $1.90 per square foot of surface for insulation.

    2. New HVAC Unit – One ton of AC is required for every 400 – 600 square feet and homes typically require 30 to 60 BTUs per square foot. Purchase according to how numerous BTUs and tons of AC you need.
    3. Ductless Mini-Split System – If you only need to add freezing air to one room, consider installing a ductless mini-split which is a little heating and cooling system with an outdoor compressor/condenser, and an indoor air-handling unit.

      Depending on the size and model, typical costs are between $660 and $4,500.

    Rather than with a joint AC and heating system – Consider heating the basement with radiant heat—a heating element under the floors—or a vented fireplace.

    1. A prefabricated electric fireplace generally costs about $280 – $1,100 installed.
    2. A vented gas fireplace can cost between $1,600 to $4,200 and $130 for installation.
    3. Radiant heating can cost about $5,000 or $4 – $5 per square foot installed for a plate-type system.
    4. Wood-burning stoves cost between $500 and $2,750 for entry to medium quality and $3,000 – $4,000 for a high-quality stove.

      Installation ranges between $842 and $3,050.

    Basement Foundations

    Basement foundation costs could well account for the biggest expense of the basement refinishing project.

    New Foundation

    The basement foundation cost for 1,200 square feet is approx.

    $17,200. The average price to pour a concrete basement foundation is $11,560 or $9.64/SF for a 1,200-square-foot basement. This cost includes excavation, foundation, concrete, retaining walls, and backfill, but the final cost includes:

    1. A soil engineer’s report for about $2,300
    2. Soil grading for $3,300

    Existing Foundation

    Concrete will always crack eventually, and any existing foundation must be inspected before a basement finish to see if it’s in excellent condition.

    Minor foundation crack repairs cost $620 or more to repair, while major repairs that require hydraulic piers can cost $10,000 to $15,000. If your foundation is sinking, mudjacking costs$3 to $6 per square foot to lift the slab.

    New Foundation Under Existing Home

    The cost can go even higher.

    1. When the basement is to be created under the existing home, it will cost an average of an additional $10,000 to jack up the foundation during the dig.
    2. Difficult soil excavation (rocks, hard clay, sloped ground) or the need for retaining walls can drive costs up an additional $5,000 to $20,000.

    Basement Finishing Permit Cost

    The average basement finishing permit cost is generally a percentage of the entire construction cost at approximately 0.65%.

    Inspections and re-inspections average out at $50 per hour. Permits are typically needed for any electrical or plumbing work, and each bedroom must own an egress window.

    All basements must own at least two exits, one being the stairs. Any work done without permits could delay the project or cause it to come to a halt. Some basement refinishing work has had to be completely demolished and redone according to code because of the lack of permits. Diverse building departments and cities will own diverse ways to calculate your permit fees, and under are two diverse examples of permit fees calculations using a formula based on the entire construction cost:

    1. Permit fee = (Construction cost) X 0.0065 (or some other modifier)


    1. Permit fee = $300 for first $25,000 + (remaining worth / 1,000) x 10 + first $300


    1. Plan Review Fee = (Permit Fee) X 0.65
