Building a basement bathroom will not only increase your usable space, but it will also increase the resale value of your home if you ever decide to sell or refinance. This job may seem like a task best left to professional, and some steps will have to be, but the majority of the project can be done by any homeowner, which will save you a ton of money at the end of the remodel.
Allowing for Drainage
One mistake that inexperienced people often make when building a bathroom in the basement is allowing for drainage. The drainage in the basement does not have the aid of centrifugal force as the rest of the house, so a sump pump must be installed underneath the concrete floor. This obviously requires some excavation work, but if you rent or purchase a jackhammer, this step is easily accomplished. Just keep in mind that the older the house is, the more set the concrete is, so the older the house, the harder the concrete will be.
After you have excavated the area for the sump pump, install it along with the rest of the plumbing. This step in the remodeling process is best left to a plumber unless you have extensive knowledge in it. After the plumbing is done, fill the hole with new concrete, making a trap door so that you can access the pump if needed.
Another mistake that is made often when building a basement bathroom is basic venting. In order to keep the moisture build up to a minimum, some type of venting needs to be installed. Depending on the location of the new bathroom, you can tie into an existing vent for an upstairs bathroom, or you can install a vent that goes through an outside wall or roof. No matter which way you choose to install one, this step cannot be skipped if you want the bathroom to last a long time without having moisture build up, which can cause mold formations.
The final step that is most commonly made is not mandatory, but it does add to the usability and comfort of the new bathroom. Since the basement has a concrete floor, many people choose not to add more flooring to it. As we all know, though, concrete floors are cold and very uncomfortable. In order to increase the comfort and usability of the basement bathroom be sure to add some type of subflooring and flooring into it. Since the concrete naturally attracts moisture, always lay some type of plastic barrier between the floor and the concrete, otherwise wetness will occur within a matter of a couple of months.
Installing a basement bathroom has numerous positive effects upon the house, and except for the plumbing and wiring that may be needed, can be done by the homeowner in their spare time. When adding in the new sump pump, some extensive labor is required in order to accomplish the job, but the use of a jackhammer will make the task simple and fast.
