Bathroom Addition

Updated: Mar 2

What You Need to Know About Bathroom Additions

Are you tired of sharing a small bathroom with your whole family? If so, adding a new bathroom might be the solution you need!

Modern homeowners often prefer to have more than one or two bathrooms, so it is quite common for a family to add an extra bathroom to their home. Doing so will add the benefits of comfort and functionality. Plus, it will add value to your home if you decide to sell.

Believe it or not, adding another bathroom isn’t quite as difficult or expensive as it sounds. We’ll go over everything you need to know if you’re considering a bathroom addition.

How Much Does a Bathroom Addition Cost?

There are several different factors that come into play when determining the final price of a bathroom addition. The biggest factor is the location of the new bathroom. You can have a new bathroom installed inside the current floorplan, as a part of the garage or basement, or as a new structure to add square footage to your home.

  • When converting existing floor space into a bathroom the price can be $8000-$1200 depending on size, ease of access, existing plumbing, and the quality of the fixtures. If you’re looking to add a luxury master bath addition, then you can expect it to run you $9000-$35,000. This, however, is your most budget-friendly option.

  • Adding a bathroom to your garage is a bit more expensive coming in at an average cost of $10000-$45,000. Garages are a great place to add a bathroom because you have more options for design and space. A great way to save money is to add a builder grade bathroom to your garage instead of building something luxurious. A builder grade bathroom is a bathroom that has the most simple fixtures with exposed materials but is still fully functional.

  • If you build a brand new bathroom, it will cost you between $50,000-$100,000. We know that seems like a steep price but this is the option with the most design and space choices. The possibilities are endless with a brand new bathroom. You can make the bathroom function the best to suit your specific needs. Because of the customizability with this option, the price will depend heavily on the size and amenities, like building a half bath instead of a full bathroom. This build option will add square footage to your home and by doing that, the value of your home will go up.

How Much Value Does a Bathroom Addition Add to Your Home?

According to Badeloft, a bathroom addition can increase your home’s value from 10-40%, depending on the quality of the bathroom. Of course, the size and type of bathroom you add also plays a role with determining the added home value, so be sure to keep that in mind.

See below for a list of different types of bathrooms:

Half bath, also known as a powder room, is a bathroom that only has a sink and toilet. If you are looking for an option that is compact and fits in a small space, this is the best option for you. A half bath is a great addition to the home for guests to use. If you have a closet you aren’t getting any use out of, then it is possible to convert it into a half bath.

Full bath, also known as a ¾ bath, is a bathroom that has a shower/tub combo, a sink, and a toilet. This is an ideal option for a home that needs more space for its residents. The average size of a full bath is 40 square feet, but it can be larger if the homeowner wants a double vanity or linen closets.

Master bath is a bathroom that contains double sinks, a toilet, and a separate shower and tub. It may also include a walk-in closet or a linen closet. A master bath can range in sizes from 40 square feet up to 200 square feet, depending on what you as the homeowner want to include. This type of bathroom is normally adjacent to the master bedroom.

What Other Factors Influence the Cost of a Bathroom Addition?

When planning a bathroom addition, you might not think about the cost that you can’t control because they aren’t optional. These things could include drywall, foundation, plumbing, insulation, roof, and wall framing. These are building materials that can’t be changed no matter your budget. However, there are some things you can control such as whether or not you add a window or what kind of shower tile you install.

Take a look at the examples below of items that can affect the cost of a bathroom addition based on your choices:

Windows – By adding a window, it will make the bathroom addition feel brighter and bigger. Windows vary in price depending on what you choose with average cost from $500-$1000 including installation. You could save by buying used or refurbishing an old window to help with your budget. Most people try to buy windows that match the other existing windows. But, the choice is all yours!

Flooring – There are several different options for flooring in a bathroom. The most budget friendly options are ceramic tile or vinyl plank. Some of the more expensive options are marble and stone flooring. Flooring comes in many different colors, prints, and shapes and can be matched with any design.

Lighting – Just like with flooring, there are many options when it comes to the lighting of your bathroom. The lighting options vary from the most inexpensive like recessed lighting to more expensive light like a beautiful, upscale chandelier.

Shower tile – Tile can be expensive, but there are several options that can help keep costs down. For example, if you get a tile that has larger pieces and is made out of porcelain, then it can be cheaper than tile that is small and made of glass or marble. The labor cost for installation depends on how tedious the labor is.

Bathroom Fixtures – Fixtures for a bathroom like faucets and hardware, are generally a reasonable price. They come in different but basic styles and finishes like chrome and brushed nickel. Some styles are more expensive with a higher end look including finishes like gold and matte.

Cabinets and Vanities – Cabinets and vanities are great accents to any bathroom. They add storage and counter space to any size bathroom. You can find vanities and bathroom cabinetry at any home improvement store from a range of prices starting at $150 and going up to $2000, depending on size and quality.
