The key aspects to constructing a new bathroom.

Value of Adding a New Bathroom

A new bathroom can do several things for the quality and value of your home. One of the most important reasons to add a new bathroom is the increase in home value. On average, adding a bathroom to your home will increase the value of your home by 10-20%. This is great for when you go to sell your home, but a new bathroom is also a very rewarding investment regardless, especially if you need it. This guide will go over the most important parts of adding a new bathroom to your home design.

Cost of Adding Your Bathroom

The price of adding a new bathroom to your home can range anywhere from $15,000 to $75,000 depending on the size of the bathroom you want to add as well as the fixtures that you plan to include. If you are just reusing space that is already in your house, you will probably be looking at the lower end of the price range, but if you are adding an addition onto your house in order to add your new bathroom, you will be looking at around the $15,000 range or possibly even more than that. One more major thing to consider is city permits. Your city may or may not allow you to add a bathroom depending on the city code, so make sure this is something you look into before you make any major decisions.

Know Where to Add Your Bathroom

The first thing you want to do when adding a new bathroom, is knowing where you want to construct it. If you have an existing bathroom that you want to demolish and start from scratch, that would be the first place to look to for constructing a new bathroom. If you have a long hallway with no rooms, it might be a good idea to consider constructed a bathroom there. If you have any big closets or extra bedroom space that you are not using, consider those areas as well. Wherever you decide to add your bathroom, make sure it is in the perfect location as far as accessibility and comfort go. If your bathroom is in an uncomfortable or hard to access location, the end result might be something you regret.

Fixtures to Include

Essential fixtures to include in any bathroom are sinks, toilets, vanities and mirrors. These are the fixtures that you absolutely need in any bathroom when starting from scratch. Vanities are classic bathroom fixtures can be used in many bathrooms. Vanities are sometimes coupled with mirrors, which is great benefit. Sinks and toilets are two more bathroom fixtures to consider. Pairing and matching your sink and toilet is a common and reliable option. A typical guest bathroom may only need these fixtures. A bathroom for personal use will need a shower, bathtub or a combination of the two in addition to the previously mentioned fixtures.


Knowing your plumbing situation is essential when constructing a new bathroom. Immediately after knowing where you want your bathroom to be, start mapping out where you want your plumbing to be. If you can manage to place fixture in the same area as existing plumbing or water lines, it can help cut down plumbing costs. It is highly recommended that you hire a professional in order to insure that everything is perfectly set up for your construction. You may want to consult a professional to help you with this area, simply because plumbing can be complicated if you don't know all of the ins and outs of your plumbing situation. If you don't foresee any issues with plumbing, check all of your options to ensure you don't run into any potential issues that could effect you in the long run.


Much of this depends on the kind of bathroom that you want. For a personal bathroom or a kids bathroom, you want to make it fairly close to the bedroom, if not attached to the bathroom. If you want a guest bathroom, make sure your planned location is easily accessible and easy to find. You also want to keep it simple. Over designing or including too many fixtures can lead to discomfort for a guest and more to worry about for you. Guest bathrooms are typically smaller so make sure the bathroom is not too cluttered. No matter the size of your bathroom, it is important to keep every fixture accessible in order to promote a comfortable and relaxing environment.

Final Note

Building a new bathroom from the ground up can take time and require many decisions. Take the time to find the necessary resources for your ideal outcome.
