Q: Why do some old houses have a toilet in the basement?

• <div><p>Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.</p><p>Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.</p></div>

Q: Does a finished basement need ventilation?

• <div><p>Although it&rsquo;s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try <a href="https://www.angi.com/articles/how-improve-ventilation-basement-remodeling-project.htm">basement ventilation methods</a> like installing vents or a dehumidifier for best results.</p></div>

Q: Should you refinish your basement?

• <div><p>Finishing a basement can provide a great return on investment, by increasing the market price of your home when you want to sell. Beyond that, there are many reasons to finish your basement. Doing so expands the usable square footage of your home, so you can enjoy it more, even as your family grows. Renovating your basement costs less in terms of time, energy, and money than having to search for and buy a new home.</p></div>

Q: How hard is it to put a bathroom in a basement?

• <div><p>Installing a bathroom in a basement isn&rsquo;t a project for most homeowners. Many parts&mdash;plumbing, electricity, and carpentry&mdash;go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner&rsquo;s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. </p></div>

Q: Is it worth it to renovate a basement?

• <div><p>Yes. Renovating your basement has a <a href="https://www.angi.com/articles/remodeling-projects-highest-roi.htm">return on investment (ROI)</a> of 75%, meaning your remodel investment will significantly increase the value of your home. Besides the ROI, your family can enjoy a larger, more usable space while you live there. </p></div>
