Installing a bathroom in a basement costs more than installing a bathroom above ground. Costs can range from $2,500 to $5,000 on average, depending on the number of fixtures and whether the plumbing must be installed from scratch or if it’s roughed in already. Basement plumbing requires special considerations to ensure proper drainage and tie-in with the main sewer line, which may not be deep enough to allow the basement bathroom plumbing to use gravity the way above-ground plumbing does. Virgil Miranda’s Construction subcontracts all plumbing work. Miranda says that sometimes the toilet alone in a basement can cost up to $2,500 because sometimes homeowners need to invest in a toilet that does not use gravity but instead a macerating function to grind waste down to prevent clogging. Miranda estimates that each bathroom fixture in a basement costs $800–$900 on average, so a full, three-piece bath could cost $3,000 for the fixtures alone. Adding a kitchenette or wet bar sink adds more to overall refinishing costs. In addition, some basements require a French drain with one or more sump pumps, which can cost up to $10,000 on average, depending on how much ground the drain covers.
Your stairs are the first thing guests will see when they walk down into your finished basement. Give them something to talk about with a staircase that’s one of a kind. Create suspended steps, light-up steps, or glass side panels. Or make smaller changes by installing patterned carpet, decorative tiles, or a unique railing. Looking for more cool staircase designs?

Visitors can find comfort and refuge in this basement thanks to an added guest suite just off the family room. Two closets offer an unexpected amount of storage in this small space and create a cozy alcove for the bed. A high ledge acts as a headboard and display area, and two space-saving wall scones light the nook. The bed faces French doors that, like the family room, take in backyard views.
Because basements are usually below ground level, water seepage and moisture issues have to be resolved before construction can start. Prior to creating a project bid, most contractors will inspect the area to check the interior floor and walls for dampness and make sure the exterior of the foundation is in good shape. Depending on how watertight the basement and foundation are, it may be necessary to protect the basement from future water damage after it’s finished, often through the installation of sump pumps. This work can cost anywhere from $700-$3,000, depending on what needs to be done. Learn more about basement waterproofing. To help prevent moisture problems, homeowners can clear downspouts and gutters of debris to ensure that they help keep moisture away from the foundation.
Finished basement made use of existing materials and transformed it into an elegant basement living room. Painted concrete floors and concrete hollow blocks walls are painted in classic white and cool gray. Exposed beams are furnished with industrial lights which provide ample lights to the room. Comfy, soft upholstered sofas and accent chair in neutral colors adds coziness, perfect place to sit back and relax. Splash of patterns and colors from the area rug, accent chair and throw pillows gives a warm and welcoming ambiance.
Plumbing - Check locally for required permits and any zoning law regulations about adding in plumbing, or whenever working with septic and sewer lines. Planning your basement bathroom directly below or close to the pipes of an existing bathroom may help reduce the overall labor and costs. Remember that all drainage lines require a downhill slope to sluice away waste water. If this isn't possible, a sewage injection pump must be installed. An approximate cost of these pumps ranges from $150-$3,000.
Your basement will likely need to be fitted with additional wires to support more lights and electronics. You will need to hire a licensed electrician if you plan to install additional overhead light fixtures, outlets and other components that require additional wiring. The cost of electrical installations depends on the exact project, but licensed electricians tend to charge between $50 and $100 per hour.

Pure design genius animated this basement remodel from lifestyle blogger Landeelu. For one, she decided to paint her doors a dark color, giving them a custom look that stands out from the cooler gray walls. Next, she added pops of interest with unique items, like the aged gold ceiling light fixture from Joss & Main. The fireplace not only adds warmth to the room for guests, but provides a welcome focal point. The result is an adorable space that can now rightfully be called an integrated part of the home.

Avoiding Finished Basement Roadblocks This post goes out to all of my fellow d.i.y. basement finishing bosses who are faced with nasty ugly basement obstacles, that are smack in the middle of Basement Progress Avenue.

Basement water leakage can cause serious problems for a homeowner. Standing water can lead to mold growth, which poses health issues. It's also a haven for bugs and other pests. Over time, concrete blocks and foundations can sustain hairline cracks. While they may appear small on the surface, they can be the start of an enormous problem, so early repair is key. The only way to rectify a basement water problem is to remove the water and seal the leaks. This may involve removing existing paint or wall coverings as well as replacing soggy beams.
Search the pro’s contractor’s license to verify they are in good standing with the state board. As an example, in California, search the California State Contractors Board to learn if the license is up to date, if they have any legal action against them and if the contractor is in good standing. Some states only require contractors licenses for residential projects based on price, so research your region to be safe. For more information on smart hiring, check out our safety tips.
But the brilliant trick she employed to disguise the too-low ceiling was to paint the walls and ceiling the same color (Farrow & Ball, Elephant's Breath). Painting the ceiling white and the walls a different color would have created a horizontal line. The eye would use this line to establish the height of the ceiling. Instead, walls and ceiling blur together, making the ceiling look higher than it really is.

There are several types of basement remodeling depending on the outcomes you want. Whether you have nothing but damp concrete walls and floors or you have a finished basement with painted walls, a pool table and a wet bar will determine the scope of work for your basement remodel and the cost. Here are some common basement remodeling projects that homeowners take on and their related costs.
Material Costs - In addition to the cost of framing and installing drywall to a basement bathroom, material costs can include: ceiling, flooring, paint, trim, toilet, sink, vanity, all fixtures, tub/shower surround, lighting, and all finishes like towel racks. Plumbing and electrical supplies also factor in to the final budget. Many material costs depend on type of product selected, the brand, and how high-end it is. Heated ceramic floor tiles cost more than basic vinyl tiles.
Take a basement spare bedroom one step further by turning your downstairs into an apartment suite. Go with a kitchenette with updated appliances and an island, a small space to put a couch for lounging, a half wall to create the boundaries of a bedroom, and a bathroom.

Old homes may suffer from sagging foundation beams as a result of shifting ground or decay and deterioration of the original building materials. Foundation beams can be raised and shored up successfully, but the right tools, like a pneumatic jack, are essential. Depending on how much the foundation beam must be raised, this job may require several days of incremental steps to complete - which means increased labor costs. Hiring professionals is the best option for this job. Expect costs to run about $10,000 for repairs like a shifted foundation.
Before you even consider color, you want to have lighting in the space figured out. If you don’t have any natural light, how are you going to brighten up the space? Will you use pot lights or track lighting, will you supplement with floor and table lamps? Your paint will look worlds different if you change your lighting after you paint, so try to sort out your lighting needs first.

If time is critical, consider a basement finishing kit. A finishing kit has insulated wall panels, and some include a walkable flooring surface and ceiling material for DIY installation. Depending on the size of your basement, these kits can be installed in a weekend. However, the floor won't be carpeted, the walls won't be painted, and there will be no electrical or plumbing. Other features such as doors, trim work, and more also need to be added.
