A bathroom addition in Long Beach can give your household more space without requiring you to move. Whether you're adding a guest bathroom, building a second full bathroom, or expanding your primary suite, the new space should work naturally with your home's existing layout.
Unlike bathroom remodeling, which updates an existing space, a bathroom addition may involve extending the home's footprint, converting available interior space, or incorporating a new bathroom into a larger home addition. If your project requires expanding the home's footprint, learn more about our home addition services in Long Beach.
EMR Builds handles bathroom additions from planning and permitting through plumbing, structural construction, and final finishes.

Ways to Add a Bathroom to Your Home
Depending on your home's layout and available space, there are several ways to build an additional bathroom.
Exterior Bathroom Addition: Extend the home's existing footprint to create space for a new bathroom.
Primary Suite Expansion: Expand an existing bedroom and bathroom area to create a larger, more functional primary suite.
Interior Space Conversion: Convert suitable existing space into a bathroom when the layout and plumbing requirements allow.
Bathroom Within a Larger Addition: Incorporate a bathroom into a new bedroom, guest suite, or larger home extension.
The right approach depends on available space, structural requirements, plumbing access, and local building regulations.
