The bathroom design question phase is not a formality. It is the moment where every correct decision later becomes possible — and where every skipped answer becomes a construction problem.
In MÉTODO, we treat the question phase as the actual start of design. No sketch, no section, no material selection happens before we understand the space through a structured set of questions tied directly to how people live.
Why the Question Phase Comes Before the Program
Most people arrive to an architecture conversation with an aesthetic in mind: stone walls, a freestanding tub, black fixtures. Those are valid preferences. They are not a program.
The program is the written list of what the bathroom must accomplish. It emerges from questions, not from images. The questions we ask before writing the program include:
- Who uses this bathroom, and at what times of day?
- Is it shared? Do the users overlap?
- Is there natural light, and from which direction?
- What is the ventilation condition — single-opening or cross-draft possible?
- How much storage is needed, and in what form?
- Is there a bathing ritual or only a shower function?
- What is the humidity tolerance of adjacent materials?
Each answer constrains the floor plan in a specific way. The question phase makes those constraints visible before any line is drawn.
What a Bathroom Program Contains
Once the questions are answered, the program becomes a document. It is short — rarely more than one page. It includes:
- Fixture count and type (shower, tub, double vanity, single vanity)
- Minimum clear dimensions for each use area
- Storage volume and preferred placement
- Lighting requirements by task (grooming, ambient, night)
- Ventilation strategy
- Acoustic separation needs
- Maintenance expectations tied to material choice
The program is not a wish list. It is a set of constraints that the design must satisfy. A bathroom that answers its program is a bathroom that works.
How the Program Drives Spatial Decisions
The section as relato is especially legible in a bathroom. The vertical dimension — ceiling height, shower niche position, window sill height — tells the story of how the room was understood.
If the program identifies a single user with a morning ritual that includes natural light on the face, the window position is determined before the plan is sketched. If it identifies two simultaneous users with different wake times, the layout separates functions in a way a single-user room never needs.
These are not design choices. They are logical outcomes of a well-asked question.
What Happens When the Question Phase Is Skipped
When architects skip the question phase, the result is a bathroom designed around a reference image. It may be beautiful. It frequently fails at function: the mirror placement creates glare, the niche falls behind the door swing, the ventilation is insufficient for a steam shower.
Clients rarely identify these as design failures. They call them inconveniences. But they trace directly to questions never asked.
In our process, revisions after the program is approved cost more because by then, structural decisions have been made. The question phase is cheap. The correction phase is not.
The Specific Questions That Change the Most Layouts
Among all pre-design questions, three change bathroom layouts more than any others:
Light direction. A bathroom facing east designs differently than one facing west. Morning grooming in east light uses the window. Evening grooming in east light needs artificial light compensation.
Steam or dry shower. A steam enclosure requires full containment, specific ventilation, and different material choices. A dry shower does not. One question, completely different spatial logic.
Cleaning access. How the bathroom will be maintained determines grout joint widths, drain placement, and whether large-format stone is appropriate for a floor that someone will actually clean weekly.
