The Average Cost
To renovation an existing space and convert it into a bathroom, you could spend as little as $2,500. However, a new addition is going to run you a minimum of $22,000. It doesn’t particularly matter where you plan to add the bathroom, the cost is going to depend mostly on whether you’re adding to your home or converting an existing space.
- Existing Space
On average, homeowners spend just over $9,000 to convert an existing space into a bathroom (roughly 100 sq ft). If you were to invest $35,000 on an upscale bathroom renovation of an existing space, it could boost your home value by as much as $21,000.
- Total Addition
A midrange addition could run as much as $50,000 while adding over $25,000 to your home’s resale value. If you want to go big with an upscale addition, then you’re edging closer to $100,000 with a $50,000 home value boost.
Let’s break it down further!
- Installing a bathtub and shower combination can run you anywhere from just under $1,000 to as much as $3,000. You have to also figure in the plumber’s rate. A shower, however, can be as cheap as just $300 (excluding labor costs).
- As far as tiling goes, you’re likely looking at $15 per square foot to tackle the flooring and $10 (per sq ft) for the walls. This will, of course, depend on the tile you choose and you will still need to factor in the cost of labor.
- Generally, the installation and cost of the toilet will run around $400 or thereabouts. There are a few factors to consider when dealing with sink installation. An under-mount can be as cheap as $40 (and as much as over $2,000). A pedestal can run anywhere from $70 to $350 and. The most expensive sink options are the vessel and corner sinks, and even they fluctuate wildly in price depending on what you choose.
- The vanity can be complicated, with labor as much as $45 hourly. Then there’s the size, a smaller option may be as little as $70, while a large luxury item could cost as much as $4,5000.
- Now, you have to consider the electrical work. There’s a need for adequate lighting, fans, and outlets. An electrician can charge anywhere from $90 an hour to $150, and that’s just for labor.
- Finally, there is the matter of regulations and permits. If you are adding extra space and building new walls, then you need a permit. Electrical work may need to be updated to ensure it’s up to code and will likely require a permit. If there are new pipes, plumbing, and waste ducts being brought to a new location, then a permit is likely necessary. Permits can run anywhere from $200.
Factors To Consider
If the addition is located near existing plumbing, then the job will be much cheaper as there will be no need to bring vents, waste lines, and plumbing to the addition.
Are you adding a practical bathroom? Or, are you more interested in a luxurious master suite addition? The scale of the job and the materials you choose will have a big influence on how much a bathroom addition costs.
What is the size of the job? Will walls be knocked down to create space? The majority of bathroom additions see an unused closet or excess space being converted, which means there is no need for an additional foundation or a roof. That makes the job much cheaper than a brand new addition. The size of the job (and the size of the bathroom itself) matters).
- Home Age
The age of your home matters. The older your home, the more likely there is electrical and plumbing work necessary to update it or bring it up to code. This is often a hidden cost that most people don’t consider until work has begun. You’re going to want to have a contingency fund to deal with issues like this if you live in an older home.
As noted above, there is always an element of the unknown when it comes to home renovations and additions. As you start to open walls and whatnot, you might run into unexpected issues, whether it’s water damage, mold, pests, or otherwise. It’s always wise to have an emergency fund to deal with any unexpected issues that may arise during the process.
