No federal, state, or local law in the United States requires you to have a bathtub in your house. Every major building code requires a dwelling to contain a bathtub or a shower, and a working shower by itself fully satisfies that rule. The confusion is common because people hear “bathroom requirements” and assume a tub is specifically mandated. It isn’t. The codes care that you have a functional bathing fixture; the choice between tub and shower is yours.
What the Building Codes Actually Say
Two codes do most of the work here. The International Residential Code (IRC) governs new construction, and the International Property Maintenance Code (IPMC) sets minimum standards for existing buildings. Both are published by the International Code Council and adopted, with local amendments, by most states and municipalities.
The IPMC states it plainly: every dwelling unit must contain its own bathtub or shower, lavatory, water closet, and kitchen sink, all maintained in safe, sanitary working condition.1UpCodes. Chapter 5 Plumbing Facilities and Fixture Requirements – IPMC 2024 The IRC’s plumbing chapter sets the same baseline for new homes: one bathtub or shower, one toilet, one sink, and one kitchen sink per dwelling unit.2ICC Digital Codes. Chapter 27 Plumbing Fixtures – IRC 2021 Notice the “or” in both. A walk-in shower, a stall shower, or any other dedicated bathing fixture counts. Nothing in either code privileges a bathtub.
Local jurisdictions can and do amend the model codes, adding requirements for ventilation, fixture clearances, or drain configurations. The core fixture requirement stays consistent, though: one bathtub or shower per dwelling. Some water-scarce regions actively encourage showers because they use less water. None prohibit bathtubs. Rules do vary by locality, so checking your municipal code before a renovation is still smart.
If You Rent, Your Landlord Still Has to Provide One
If you rent, the legal obligation shifts to the landlord. Nearly every state recognizes an implied warranty of habitability, which means the landlord has to keep the unit livable throughout your tenancy. A working bathing fixture is a core part of that standard.
The IPMC applies to rental units the same way it applies to owner-occupied homes: the unit needs its own bathtub or shower, lavatory, and toilet in safe working condition.1UpCodes. Chapter 5 Plumbing Facilities and Fixture Requirements – IPMC 2024 A landlord who provides only a toilet and sink with no bathing fixture at all would violate habitability standards almost everywhere. A landlord who provides a functional shower and no tub is fully compliant.
If your bathing fixture breaks and the landlord ignores repair requests, most states give you options: withholding rent, repair-and-deduct, or lease termination. The exact remedies depend on your state and local law, but the underlying principle holds. You are entitled to a working place to bathe.
Buying, Selling, or Refinancing Without a Bathtub
Even though the law doesn’t require a tub, mortgage lenders can care about what bathing fixtures a property has. Government-backed loans come with their own property standards, and appraisers check whether a home meets those standards before the loan closes.
FHA Loans
Properties financed through FHA loans must meet HUD’s Minimum Property Standards, which require adequate plumbing facilities and look to local codes on bathroom fixtures.3eCFR. Subpart S Minimum Property Standards The FHA does not require a bathtub specifically. A home with only a shower can pass an FHA appraisal as long as the bathroom is functional and meets local code.
VA Loans
Standard VA loans require adequate bathing facilities, and a shower satisfies the requirement. One narrow exception sits inside the VA’s Specially Adapted Housing program, which actually requires a roll-in shower rather than a bathtub for adapted units, reflecting the program’s accessibility focus.4Veterans Affairs. SAH Builder Lesson 5C – MPRs Primary Bathrooms For ordinary VA purchases, no tub is required.
Resale
Resale is where the bathtub question gets practical rather than legal. Real estate professionals generally recommend keeping at least one tub in a home, particularly in neighborhoods that attract families with young children. Parents of small kids often view a bathtub as a necessity, and removing the only tub in a house can narrow your buyer pool. A high-quality walk-in shower in a well-designed bathroom won’t necessarily hurt your sale price, especially in markets where the typical buyer is a single professional or empty-nester. The financial impact depends on your local market and buyer demographics, not on any legal requirement.
Accessibility Rules Affect the Choice in Some Housing
Federal accessibility standards shape fixture choices in certain buildings. The Fair Housing Act requires covered multifamily buildings (those with four or more units built after March 1991) to include accessible design features. When a stall shower is the only bathing fixture in a covered unit, it must measure at least 36 inches by 36 inches and include reinforced walls for later installation of grab bars.5HUD USER. Fair Housing Act Design Manual – Requirement 7 The law doesn’t require a tub in these units. It requires that whichever fixture is installed can be adapted for people with disabilities.
The ADA Standards, enforced by the U.S. Access Board, take a similar approach for public and commercial facilities. Bathing rooms must include at least one accessible shower or bathtub, and the standards explicitly allow equivalent alternatives as long as they provide equal or greater accessibility.6U.S. Access Board. Chapter 6 Bathing Rooms In transient lodging like hotels, a portion of accessible guest rooms must have roll-in showers with folding seats.
Historic Homes and Tiny Homes
Historic properties sometimes get flexibility that newer buildings don’t. The National Historic Preservation Act of 1966 established the National Register of Historic Places, and buildings listed on it or within designated districts can qualify for code exemptions when strict compliance would threaten, degrade, or destroy historic features.7National Park Service. Preservation Brief 51 – Building Codes for Historic and Existing Buildings A 1920s home with an original clawfoot tub but no shower generally wouldn’t be forced to add one. The exemption preserves what’s already there; it doesn’t eliminate the requirement for basic sanitation, so a historic bathroom lacking any bathing fixture would still have to add one during a renovation.
Tiny homes follow the same core rule. Jurisdictions that have adopted tiny house appendices to their building codes generally require the same plumbing fixtures as a standard home: one toilet, one sink, and one bathtub, shower, or combination unit. A compact shower stall is enough. The bigger question for tiny homes is whether yours is classified as a permanent dwelling or a recreational vehicle. A tiny home on a foundation that goes through normal permitting falls under residential codes. A tiny home on wheels may be classified as an RV, with different and often less stringent standards. If you plan to use one as a primary residence, confirm with your local building department which codes apply.
What Happens If a Home Has No Bathing Fixture at All
For homeowners, the consequences of having no bathtub or shower are mostly practical. No inspector goes door to door checking whether you have a working shower. Code compliance comes into play when you pull a permit for renovations, sell the property, or refinance with a government-backed loan. At that point, an inspector or appraiser will flag the absence of a bathing fixture, and you’ll need to install one before the transaction or permit proceeds.
For landlords, the stakes are higher. Failing to provide a functioning bathing fixture violates habitability standards. Local housing authorities can issue fines or require mandatory repairs, and persistent violations can lead to loss of a rental license. Tenants have legal remedies that vary by state but commonly include rent withholding, repair-and-deduct, or lease termination.
So the answer to the original question is clean. No law in the United States requires you to own a bathtub. Every relevant building code gives you the choice between a tub and a shower, and if your home has a working shower, you have met the legal standard.
