Start your dimensioned design drawing with the priority areas of the plan. These are the ele­ments that are not moveable, demand the most space, or are most important to the client. For example, you might start your dimensioned drawing with the toilet area because plumbing con­nections dictate the location. Or you might start with a shower, because that is going to be the focal element.

Let’s say you are going to start with the toilet area. Place the toilet, draw the centerline, and dimen­sion the needed clearances on either side of the toilet. Planning Guideline 20 recommends 18 inches (457 mm) of clearance on either side of the toilet, so place the toilet (in its existing location) so that there is 18 inches (457 mm) of clearance from the centerline to the wall (see Figure 10.8). An ad­ditional 18 inches (457 mm) of clearance is needed on the other side of the toilet.

PRIORITY AREASПодпись: FIGURE 10.8 in this example, based on the visual diagram in Figure 10,6 for clients Adia and Leroy, the toilet compartment is placed first as this loca-tion is preferred by the client, NKBA
In our example, the toilet and clearances take 36 inches (18 inches + 18 inches) (914 mm = 457 mm + 457 mm). Because the toilet will be in a compartment, an additional 4 1/2 inches (115 mm) of wall thickness must be included in our calculations (only one wall thickness is needed as the toilet compartment is against the room wall). Therefore, the toilet compartment uses 40 1/2 inches (1029 mm). The total dimension of the wall where the toilet is placed is 177 inches (4496 mm). So we can determine how much space is remaining for the placement of the jetted tub and custom shower, as is shown here and illustrated in Figure 10.8.

If there is a second priority area in your plan, follow the same procedure for placing the fixture, cabinetry, or other elements. Determine the needed clearances, and subtract from the overall wall dimension. For example, Figure 10.9 shows the placement of the custom shower in the bathroom, after the toilet has been located. In our example, we have allowed 6 1/2 inches (165 mm) for the wall between the shower and the bathtub, so that there is room for plumbing in the wall (wet wall) as well as the installation of ceramic tile—while maintaining a minimum clear dimension of 48 inches (1219 mm) in the shower interior.

After placing the custom shower, verify the remaining wall length, as follows:
