BATH & TOILET
Designing a bathroom occurs through a series of steps and procedures.
Understanding the client’s goals for the space, while incorporating considerations
for hygiene, safety, ergonomics and storage, is the designer’s goal. Building
construction integrity and code compliance must be achieved. Accomplishing this
requires an organized approach to gathering pertinent information, simplifying
the decision-making process, and setting priorities.
There are five basic steps in bath design:
1. Gathering client and project information
2. Setting priorities
3. Researching and selecting products
4. Doing design and layout (space planning)
5. Drawing up a plan checklist before submitting a design

Design Goal. Establish a visual style and functional goal for the space.
Space planning decisions and product selections will be made based on
this goal.
Space planning. Analyze the overall space and possible design options
for the bath. Bubble layouts for larger spaces identify various areas of
activity within the room and begin the space planning process.
Principles and elements of design. Carefully examine volume, form, line,
texture, and light, as well as scale, proportion, balance, contrast, and
unity.
Plumbing fixtures. Plumbing fixture selections should reflect the client’s
ergonomic profile, style, and function within the space.
Installation criteria. Reviewing the manufacturer’s product installation
guidelines with the plumber and contractor prior to laying out final
plans enables you to note practical information in the plans and
specifications. The plumber and contractor can often anticipate and
identify installation problems that may be avoided through design. If
the contractor has not been selected by the client, a good working
relationship with a licensed plumbing contractor and a manufacturer’s
representative will allow you to take advantage of their practical
knowledge.

Mechanical systems. Before any construction is started, or final plans are complete,
carefully consider what must be done with the home mechanical systems. The
location of air-conditioning/heating ducts and registers, return air grills and chases,
vents, water supply lines, and drain pipes must be established.
Lighting. A functional space that blends natural and artificial light is the goal of the
lighting system. A lighting plan consisting of four layers of light is best in the
bathroom:
1—Ambient light for safe passage into and out of the bath.
2—Task light for specific grooming and hygiene activities.
3—Accent light for decorative features in the space.
4—Natural light for mixing with artificial light when the bathroom has a natural
light source.
It is the designer’s responsibility to research and apply any lighting codes to the
design, even when a lighting designer is involved.
Textures and surfaces. The way(s) in which materials may impact the space visually
and practically upon installation must be anticipated at the beginning of the design
phase, so that allowances for material weight and installation can be made. A stone
or tile wall is a good example
