Permit Requirements and Building Codes: What to Know Before Your Tub to Shower Conversion

Don’t Get Caught Off Guard: The Essential Permit and Building Code Guide for Your Tub to Shower Conversion

Converting your bathtub to a shower can transform your bathroom into a more functional and modern space, but before you start demolition, understanding permit requirements and building codes is crucial for a successful project. When you make changes to plumbing, electrical, or structural components of your home, you need a permit from the Department of Buildings, and failing to obtain proper permits can lead to costly delays, fines, and safety issues down the road.

When Do You Need a Permit for Tub to Shower Conversion?

A permit is necessary to make any alterations to the existing plumbing system, which includes most tub to shower conversions. Changing from a bathtub to a tub/shower or to a walk-in shower becomes slightly more complex, but not substantially, yet it still typically requires permits due to plumbing modifications.

Specifically, you’ll need permits when your conversion involves:

Essential Building Code Requirements

Understanding current building codes ensures your conversion meets safety standards and passes inspection. Key requirements include:

Plumbing and Water Safety

Shower and tub/shower control valves shall be pressure balancing set at a maximum 120 degrees F, and individual shower valves shall be balanced-pressure, thermostatic or combination balanced-pressure/thermostatic valves that conform to specific requirements and shall be equipped with a means to limit the maximum setting of the valve to 120°F (49°C).

Shower Dimensions and Safety

Minimum shower size is 1024 square inches (30″ circle), and shower without threshold shall be considered a wet location and shall comply with California Building, Residential, and Electrical Codes. Additionally, shower compartments shall be not less than 30 inches (762 mm) in minimum dimension measured from the finished interior dimension, and the minimum required area and dimension shall be continued to a height of not less than 70 inches (1778 mm) above the shower drain outlet.

Electrical Requirements

Provide a 20 AMP GFCI protected electrical outlet within 36″ of the outside edge of each bathroom sink basin, and luminaries located within the actual outside dimensions of the tub, shower, and ceiling suspended paddle fans, up to 8 feet vertically from the top of the bathtub rim or shower threshold, shall be marked as suitable for damp locations.

The Permit Process: What to Expect

Only a licensed professional can prepare and submit your bathroom remodel permit application, including licensed professionals who can submit applications for NYC home renovations. Many permits, such as LAA (Limited Alteration Application) or electrical permits, can be approved within a few weeks, while alteration permits can take up to a few months to get approved.

If you need a permit for your bathroom remodel, the costs can be calculated as a flat rate for specific scopes of work or as a percentage of the cost of the project, and in some areas remodeling permit costs might be as high as 10%, but it’s usually less.

Working with Professional Contractors

For homeowners considering a tub to shower conversion Nassau County residents should work with experienced professionals who understand local requirements. Companies like OMG Shower Doors, proudly serving Nassau and Suffolk counties for over 20 years, bring decades of experience in glass design and installation as a family-owned business with unwavering commitment to quality and customer satisfaction.

As a local Nassau County company, they maintain relationships with customers long after installation, having served the area for over 20 years as a family-owned business that measures, fabricates, and installs everything themselves—no subcontractors or middlemen.

What Doesn’t Require a Permit

Not all bathroom updates require permits. Simple repairs or direct replacement of existing faucets or fixtures such as toilets, shower fixtures, and sinks are considered cosmetic work and do not require a permit, and a direct bathroom vanity swap with no plumbing being relocated will not require a permit.

The replacement of the towel bars, mirrors, paint, and floor coverings where no other work is included is considered a maintenance item and no permit is required for these items.

Consequences of Skipping Permits

You can choose to ignore the permits, but that is highly inadvisable as your city can be a nightmare down the road. Skipping permits can result in stop-work orders, fines, and costly fixes later.

Regional Considerations

Requirements vary between cities and counties across the country, and permit requirements vary between states and local municipalities, so be sure to check your local requirements. For Long Island residents, areas like Old Brookville follow Nassau County building codes, with the Town of Oyster Bay building department reviewing plans and conducting inspections during the project, with permit costs typically ranging from $200-500 depending on project scope.

Planning Your Project

With any remodeling project, you should create a plan where you decide who to hire for your renovation team, and for a project with any layout changes, whether they’re plumbing or electrical changes or not, you’ll need to work with a registered architect or a professional engineer.

Permitting is not just a bureaucratic hurdle; it plays a pivotal role in ensuring quality, safety, and legal compliance throughout your remodel, guaranteeing that your remodel adheres to local building codes and regulations, ensuring structural integrity and safety.

Before starting your tub to shower conversion, consult with local building authorities and experienced contractors who understand your area’s specific requirements. Proper planning and permit compliance will ensure your project proceeds smoothly and results in a safe, code-compliant bathroom that adds value to your home.
