After your new bathroom is complete, or you have remodeled an existing space, get it inspected to ensure all plumbing and electrical installation are done correctly. If your bathroom needs to be installed from the ground up, expect to pay somewhere between $6,000 and $15,000 for the entire project. If your basement is already finished but does not yet have the necessary plumbing for a bathroom in the space, you can expect to pay between $200 - $500 to hire a plumber.
An unfinished basement serves as a valuable blank canvas. The finishing process begins with basics such as hanging and painting drywall and installing plywood floors at a relatively low cost. Basement finishing means taking a space that currently is not livable and transforming it into a space you can use and enjoy. In an unfinished space, there may be nothing but a concrete floor, exposed pipes and electrical, and no walls or only the barest of wall framework in place. On average, the cost to refinish will fall anywhere between $6,500 to $18,500, or more for larger spaces.
You can fit a full bathroom with tub/shower combination in a room that measures 40-square feet. However, on average, a smaller bath (with just a stand-up shower) or a half-bath usually needs to be about 30-square feet for comfort and functionality. Depending on the basement space and layout, you may be able to go with a larger 60-square feet or more bathroom space. Creating bathroom with a separate water closet may require 100-square feet or more.

Consider what you can do yourself. Finishing your basement is a full process and is not easy. But if you’re looking to save money and are quite handy, consider waterproofing the basement yourself. Basement waterproofing with SANI-TRED® uses a proven application process that is perfect for the do-it-yourself community. You can (and should) hire contractors for specialized tasks like plumbing or electrical, but many can do the waterproofing yourself for less.
Basement remodeling adds value to your home, increases your useable living space, can protect your foundation from moisture damage, and looks great. Many people remodel a basement to create space for an aging parent or to make room for more children. Another reason for basement remodeling is to create a rentable space that is separate from the rest of your home for a long-term renter or for short-term renting.
Planning is the first stage with any basement bathroom installation. For a basement that's designed as a recreation room, work space, or kids' play area, a half-bath (stool and sink, but no shower or tub) is adequate. A basement with bedroom or en suite needs a full bathroom. Knowing how you plan to use the basement living space typically dictates the functional purpose of its bathroom.

Hardwood, laminate and tile flooring significantly increase the cost to finish a basement. Sebring, who calls carpet “the king of basement flooring,” says many people are scared about the consequences if a carpeted basement floods. But even top-of-the-line vinyl and tile has to be pulled up if there’s serious water damage, he says, and you can replace carpet multiple times for the same cost of installing hard flooring once.

Your foundation should be inspected prior to finishing your basement. You don’t want to cover up any structural damage that would be identified in an inspection by installing framing and drywall. If items such as pipes have rust, the problem may be humidity instead of a leak, but it can be just as damaging. Waterproofing the basement and using a dehumidifier helps reduce dampness and the risk of mold development.
The basement depicted here had unused space underneath the stairs. Why not transform this area into a storage or display area instead? These homeowners found some usable square footage in their home by remodeling their basement into a space-conscious hangout, an inventive and creative strategy that shows you don’t have to substitute style for function.
