In health care design, there are few debates as surprisingly passionate as the “great toilet placement discussion.” Architects sketch it. Nurses argue it. Facilities teams worry about it. Infection preventionists raise eyebrows over it. Patients? They usually have no idea the amount of angst that went into planning the location of the bathroom, they just hope they can find it before the IV pole becomes a weapon of mass destruction.
Welcome to the world of inboard versus outboard toilets in hospital patient rooms. For those outside the health care design universe, this may sound like a very niche issue. But toilet placement affects everything from patient falls and staff workflow to plumbing costs and family privacy. In fact, the humble bathroom location can quietly shape the entire patient experience.
So how do you choose?
First Things First: What’s the Difference?
Inboard Toilets
An inboard toilet is positioned closer to the corridor side of the patient room. Typically, the bathroom shares plumbing walls with adjacent rooms and sits near the entry door.
Outboard Toilets
An outboard toilet is located closer to the exterior wall or window side of the room, often near where the patient bed is positioned.
Simple enough. Yet somehow this design decision has sparked more debate than carpet versus luxury vinyl plank in a nursing station.
The Case for Inboard Toilets
Pros
1. Better Observation from the Corridor
One of the biggest advantages of inboard toilets is visibility. Staff entering the room often have clearer sightlines to the patient.
That means nurses can quickly assess:
Is the patient trying to climb out of bed?
Did someone unplug three devices and create an interpretive dance of cords?
Is the family member sleeping upside down in the recliner again?
Improved visibility can contribute to fall prevention and faster response times.
2. Efficient Plumbing and Infrastructure
Inboard bathrooms typically stack more efficiently in multistory hospitals. Shared plumbing walls can reduce:
Construction costs
Maintenance complexity
Mechanical coordination headaches
The number of meetings where someone says, “We just lost six inches above the ceiling.”
And in hospital construction, six inches can apparently determine the fate of civilization.
3. Cleaner Exterior Wall Design
Keeping bathrooms away from exterior walls allows for:
Larger patient room windows
More natural light
Better views
Research consistently supports the positive impact of daylight and nature views on healing, mood, and staff well-being.
Cons
1. Longer Walking Distance for Patients
If the patient bed sits farther from the bathroom, patients may have a longer path to travel.
Translation:
More opportunity for “I thought I could make it without calling the nurse.” That can increase fall risk for certain populations.
2. Potentially Less Family Privacy
In some layouts, the bathroom entry becomes visible from the corridor or family zone, making the room feel less private.
And nobody wants an audience during a 2 a.m. shuffle to the restroom while wearing hospital socks with zero traction.
The Case for Outboard Toilets
Pros
1. Shorter Distance from Bed to Bathroom
This is often the strongest argument for outboard bathrooms.
The toilet is closer to the patient bed, which may:
Reduce walking distance
Improve patient independence
Support mobility programs
Lower urgency-related accidents
For certain patient populations—especially orthopedic or elderly patients—this can be a meaningful advantage.
2. Improved Acoustic Buffering
Outboard bathrooms can create a sound buffer between neighboring patient rooms.
Because nothing says “restful healing environment” like not hearing your neighbor sneeze, snore, or loudly explain fantasy football statistics to a night nurse at 3 a.m.
3. More Residential Feel
Some designers feel outboard bathrooms create a more hospitality-like patient experience. The room may feel less institutional and more intuitive.
This can support patient comfort and satisfaction scores.
Cons
1. Reduced Staff Visibility
Outboard layouts can create blind spots from the corridor. Staff may not immediately see patient movement or distress.
That means greater reliance on:
Nurse rounding
Monitoring technology
Bed alarms
The magical sixth sense experienced nurses somehow develop
2. More Complex Infrastructure
Outboard toilets often require longer plumbing runs and more coordination with exterior walls and windows.
Which translates to:
Higher construction costs
Potential maintenance complexity
More meetings involving redlined drawings and coffee-fueled despair
3. Potential Daylight Loss
Bathrooms placed along exterior walls may reduce window area and natural light penetration.
And nobody wants the best window view in the room to belong exclusively to the toilet.
So…Which One Is Better?
The honest answer?
It depends.
(Health care designers everywhere nodded knowingly.)
The right solution should align with:
Patient population
Care model
Staff workflow
Safety priorities
Facility operations
Budget
Future flexibility
For example:
An orthopedic or rehab unit may prioritize shorter patient travel distances.
A medical-surgical unit may prioritize visibility and staff efficiency.
Behavioral health environments introduce entirely different considerations.
Universal room strategies may favor adaptable layouts over specialization.
There is no universally “correct” answer—only the best answer for the operational goals of the organization.
Questions Every Planning Team Should Ask
Before deciding on inboard versus outboard toilets, teams should explore:
What are our highest patient safety priorities?
How will nurses observe patients?
What populations are we serving?
How important is daylight and exterior access?
What are our long-term maintenance implications?
How does this impact standardized room design?
Are we optimizing for patient independence or staff visibility—or both?
Most importantly:
Have we actually involved frontline staff in the conversation?
