Bathroom Expansion: Learn the Basics
From the cost to expand bathrooms to the top considerations, South Land Remodeling explores the fundamentals of expanding the restroom.
How many bathrooms does your home have, and are they big enough for your family? Perhaps when you bought your home one and a half bathrooms were enough for two people. But now, your family (or possessions) are growing and one and a half bathrooms just won’t cut it anymore. Or, maybe you dream of transforming your currently stale restroom into a large spa-like oasis. In either scenario, a bathroom expansion can provide you and your family with the added space and aesthetic you desire.
What is a Bathroom Expansion?
A bathroom expansion takes a bathroom renovation a step farther. The expansion process refurbishes a bathroom while also creating additional square footage. It can involve increasing the overall size of an existing bathroom or turning a half bath into a full bath. When done right, it also adds to the home’s overall real estate value by creating more liveable square feet within the home.
But where do you get the space to expand? When expanding your bathroom, you essentially have two options. First, you can utilize space from within the house, such as an adjacent closet, hallway, bedroom or spare room. Or, you can complete a bump-out.
A bump-out will add additional square footage by tearing down an exterior wall(s) and expanding outward. Bump outs will typically expand the bathroom 12 to 15 feet.
The Cost to Expand a Bathroom
The cost to expand a bathroom depends on a variety of factors including:
Electrical Wire Rerouting
Engineer and Architect Costs
Materials and Labor Costs
Size of Expansion
The average cost of a bathroom expansion, ranges from $50,000-$60,000. As a point of comparison, a standard bathroom remodel costs around $30,000.
Top Bathroom Expansion Considerations
Plumbing & Electrical
Will your contractor need to move or add plumbing and electrical materials?
If you’re interested in adding a jetted tub or additional lighting, for example, plumbing and electrical adjustments will be needed. Or, if you’re interested in rearranging large appliances such as the sink and toilet, there may need to be larger plumbing changes.
Be sure to get detailed quotes on plumbing and electrical so you can accurately craft your overall budget.
Bathroom Sink or Double Vanity
Do you need a simple bathroom sink or a double vanity?
A single bathroom sink may be sufficient for a half or secondary bath, but a double vanity is a perfect addition to a primary bathroom. When deciding between the two vanity types, consider the amount of storage needed and whether you need multiple stations for people to get ready at once.
Another helpful feature could be a seated makeup station!
Flooring Installation & Windows
Starting at the bottom (literally and figuratively!), you’ll have to consider the type of flooring you want.
Once you’ve decided on flooring, move upward to the walls and ceiling. Where will you place the windows? How much natural light do you want? A skylight can soak the room in sunlight while maintaining privacy.
Shower vs. Bathtub (or Both)
Do you want a bathtub, shower or both?
For some, a shower big enough for two people may be the mark of luxury, while others may desire a single shower and separate soaking or clawfoot tub, for example.
If you’re interested in a mid-range bathroom remodel, opt for a combination bathtub and shower.
Walls & Storage
When designing the bathroom of your dreams, don’t forget to consider privacy and storage. Use half walls to create separate areas or full walls to enclose the toilet in its own private space.
And don’t forget to add open or closed storage options, such as closets, cabinets or shelves. The latter is ideal for combining storage and style.
