A three-quarter bathroom, sometimes called a “3/4 bath,” is a bathroom that contains a toilet, sink, and shower, but no bathtub. It’s an efficient and popular bathroom layout for homes, apartments, and condos where space is limited.

What is a Three-Quarter Bathroom?

A three-quarter bathroom gets its name because it contains three out of the four major fixtures found in a full bathroom – a toilet, sink, and shower. The missing component is a bathtub. Here are the key features of a typical three-quarter bathroom:

  • Toilet – Most three-quarter baths contain a standard toilet with a tank and bowl. Some compact models may use a wall-mounted toilet instead.
  • Sink – This is usually a pedestal sink or vanity sink. Pedestal sinks provide an open, leggy look while vanity sinks offer more storage.
  • Shower – Showers are fully enclosed by shower doors or curtains. Some have a tub/shower combination.
  • No Bathtub – The lack of a bathtub helps conserve space in small bathrooms. It also lowers remodeling costs.
  • Adequate Storage – Well-designed 3/4 baths maximize storage with floating shelves, wall cabinets, under sink drawers, and other built-ins.
  • Proper Ventilation – Exhaust fans, skylights, and windows help control moisture and prevent mold/mildew growth.

In essence, a three-quarter bath contains all the necessities for daily hygiene and getting ready, minus the space-hogging bathtub.

Three-Quarter Bathroom Layouts

Three-quarter bathroom designs can vary in shape and configuration. Here are some of the most popular layouts:

Single Orientation

This simple layout orients all fixtures along one wall. It’s easy to navigate and budget-friendly. However, it also feels cramped due to limited open space.


The sink and toilet sit perpendicular to the shower enclosure, creating an L-shaped flow. This layout feels more open and makes smart use of corner space.


Fixtures surround the perimeter of the room in a U formation. This creates a spacious feel and easy access from any direction. However, it requires more floor space.


The shower is placed in one corner with the toilet and sink across from it. This asymmetrical design adds visual interest and flexibility.

When designing your three-quarter bath layout, consider existing plumbing locations and your preferred traffic flow. Place fixtures in a practical sequence that matches your habits.

Three-Quarter Bathroom Size

What are the typical dimensions for a 3/4 bathroom? Here are some common sizes:

  • Compact – 25-35 sq ft – Very tight space for one person. Best for powder rooms.
  • Standard – 35-55 sq ft – Comfortable for one person. Tight for two people getting ready simultaneously.
  • Spacious – 55-65+ sq ft – Allows two people to comfortably use the bathroom together.
  • ADA Accessible – 60 sq ft minimum – Meets Americans with Disabilities Act requirements for wheelchair access.

The ideal size depends on your needs. Just make sure there is enough clearance around fixtures and sufficient storage for towels and toiletries.

Three-Quarter Bathroom Design Tips

Follow these design tips to make the most of your three-quarter bath:

Use Wall-Mounted Fixtures

Wall-mounted toilets and floating vanities save inches of precious floor space versus freestanding models. Go for wall-mounted fixtures whenever possible.

Include Ample Storage

Build in shelving, cabinets, and drawers to keep the space neat and organized. Use every bit of available wall space.

Select Space-Saving Fixtures

Corner sinks, compact pedestal sinks, and narrow shower enclosures conserve square footage. Look for slender, low-profile fixtures.

Install Large Mirrors

Big mirrors visually expand the room, making it feel more open and airy. Surround them with bright lighting for grooming tasks.

Use Glass Shower Doors

Frameless glass doors allow light to penetrate the shower enclosure, making it appear more spacious.

Choose Dual Purpose Fixtures

Some bathroom sinks come with removable countertops that convert into shelves. This adds storage without consuming floor space.

Use Light Colors

Painting the walls and cabinetry white or light gray keeps the room feeling bright and roomy. Avoid dark colors.

Add Windows or Skylights

Natural light also makes small bathrooms feel more expansive. If adding a window isn’t feasible, install a solar tube skylight.

Install Radiant Floor Heating

Heated floors warm up a small bathroom quickly without taking up wall space for a radiator.

Three-Quarter Bathroom Cost

What’s the cost to remodel a three-quarter bathroom? Here are typical price ranges:

  • Low Budget – $2,500-$5,000
  • Keep existing layout. Replace fixtures. Use stock cabinets.
  • Mid Range – $5,000-$12,000
  • Revamp layout. Install new tub/shower unit. Use semi-custom vanity and tile.
  • High End – $12,000-$25,000+
  • Full reconfiguration. Luxury fixtures. Custom cabinetry and tile. Heated floors.

Many factors influence cost, including layout changes, material grades, permit fees, and labor. Expect to invest 10-15% of your home’s value if doing a full three-quarter bath overhaul.

Hiring a Contractor

We recommend hiring a licensed contractor for any three-quarter bathroom remodeling project. Here’s what to look for:

  • Experience with Bathrooms – Search for contractors who specialize in bathrooms specifically, not just general residential remodels.
  • Knowledge of Building Codes – Bathrooms have strict plumbing, electrical, ventilation and accessibility regulations. Make sure your contractor is up to code.
  • Attention to Waterproofing/Moisture Control – Bathrooms require extra diligence to prevent leaks and moisture damage. Your contractor should explain their waterproofing methods.
  • Design Skills – Maximize your compact space by hiring a contractor adept at bathroom layouts and storage solutions. Ask to see photos of previous bath projects.
  • Project Management Skills – Juggling plumbing, electrical, tile, carpentry, and more is complex. Choose an organized contractor who can coordinate all the moving parts.

Take time to check references and reviews. A skilled bathroom contractor is worth the investment.

Frequently Asked Questions

What is the standard size of a 3/4 bathroom?

A standard three-quarter bath is 35-55 square feet. This provides a comfortable amount of space for one person to use the toilet, sink, and shower stall.

Is a 3/4 bathroom ADA compliant?

To meet Americans with Disabilities Act (ADA) requirements, a 3/4 bath must have at least 60 inches diameter of clear floor space for wheelchairs to turn around, along with grab bars and accessible controls. The toilet must be 17-19 inches high.

What’s the difference between a 3/4 bath and full bath?

A full bath contains four fixtures – toilet, sink, shower, and bathtub. A three-quarter bath has only three fixtures, omitting the bathtub. This makes a 3/4 bath smaller and less expensive to remodel.

Can you install a bathtub in a 3/4 bathroom?

It is possible to replace the shower stall in a 3/4 bath with a bathtub, converting it to a full bath. However, this requires reframing the walls and moving plumbing and electrical lines. Adding a tub to a small 3/4 bath may result in very cramped quarters.

Is a 3/4 bathroom enough for a family?

A 3/4 bath can work for a small family if it is sized generously, around 55 sq ft. The lack of a bathtub makes it tough for bathing small children though. Having at least one full bath is better for family households.

What’s the cost to add a 3/4 bathroom?

Typical costs are $5,000 – $12,000 to add a three-quarter bath if there is existing plumbing and electrical in the vicinity. Prepping the rough-in plumbing can add $2,000 – $6,000+. The cost is also influenced by layout, finishes, and local labor rates.


With a pragmatic layout that includes all the essential fixtures – toilet, sink, and shower stall – a three-quarter bathroom offers an efficient way to add a half bath or update an outdated powder room.
