Step 2. POOL LAYOUT
When laying out the spa, note that the dimensions are to the outside edge of the spa coping. Most permit plans
are measured to the water's edge. The coping of a Viking spa is approximately 6" on all sides. There is a difference of
12" between the length and width dimensions in the installation guide and those of the permit plans. Depending on the
customer and the local building inspector, this fact can be a critical consideration. Distances between the water's edge
to most property lines, electrical lines, and other structures such as houses, garages, sheds and patios must be exact to
plan specifications.
Start with outside layout of spa, then add additional 6" around perimeter of spa. Place stakes in the ground at
each corner of the rectangle as shown in Figure 1. Use spray paint to follow the contour of the string. Remove the string
and stakes, leaving only the outline of the spa.
Step 3. ELEVATION
Elevation and grade of the spa area are two of the most often overlooked or miscalculated variables in the
installation process. While considering all the variables concerning elevation and grade, always remember that you
want water to run away from the spa. Before excavation, use the provided Installation Planning Guide to calculate all
critical measurements (Form 1).
Check the four corners of the spa layout with the aid of a transit level or a sight level to determine the highest
corner. This corner will be used in planning the elevation of the spa. In a typical installation, the elevation of the spa
should be 4-6 inches above the existing grade around the spa. However, careful consideration should be given to
spa type, size and drainage of the future spa deck, as well as the elevation of the surrounding landscape and existing
structures, patios and sidewalks.
