Competition pool basins may be designed in accordance with the standards of the sanctioning organization.
Competition pool basins that do not comply with s. SPS 390.10 (8)
and made available for open swim shall be permitted only where another pool or water attraction that complies with s. SPS 390.10 (8)
is available at the site for open swim.
(2) Stress relief.
Provision shall be made for the relief of stress to basin walls and floors which may occur as a result of unbalanced hydrostatic pressures.
Basins that include diving apparatus shall conform to one of the following:
The basin shall comply with the standards of a sanctioning organization acceptable to the department.
The design of a basin that includes a diving area shall comply with the profiles in Figure 390.11-1 and Table 390.11-1.
Diving Area Dimensions
* No limiting dimension.
** Distance is as required by the diving equipment manufacturer.
1 The D-1 measurement shall be taken at the end wall or not more than 6 inches from the wall.
2 The diving board length extending over the pool shall not be less than “A" and in accordance with the diving equipment manufacturer's installation instructions.
3 This dimension is only applicable to pools with wall inlets.
Protrusions, extensions and other functional elements within a basin may not create a safety hazard.
Protrusions, extension and other functional elements may not negatively impact the circulation system.
When an obstruction is a recreational object in water of 24 inches or more in depth, the obstruction shall be a color that contrasts with the color of the basin.
Basin obstructions in public swimming pools shall be no more than 2 feet in diameter, protrude undiminished in diameter to at least 5 feet above the pool floor and no less than 3 feet above the water level.
Obstructions including handrails, exercise equipment and therapy structures may only be installed in therapy pools.
Stair and ladder handrails are not considered basin obstructions when installed in accordance with s. SPS 390.12
Except for vanishing edge designs, basin walls shall extend above the highest water level at all times during operation.
Protruding corners shall be rounded so as to protect users from lacerations.
(b) Interior walls and common walls.
In addition to the requirements in par. (a)
, interior walls and common walls may not exceed 18 inches in width.
Bulkheads may be installed only in pools with a department of health services-approved lifeguard staffing plan that addresses supervision of the bulkhead.
All pool interiors shall be light in color, having a value of 6.5 or greater on the Munsell color-order system.
All colors, patterns or demarcation lines may not negatively impact observer's visualization of bathers.
All demarcation lines shall be of contrasting color to the pool interior.
Basin floor slopes may not exceed 1:12 in water depths less than 5 feet.
Basin walls shall be joined to the floor with a tangent radius.
For areas less than 5 feet in depth, the maximum radius between the floor and the basin wall shall be 6 inches.
SPS 390.11 Note
See ch. SPS 390 Appendix
for information on measuring the radius dimension.
Basin depths for diving areas shall comply with Table 390.11-1.
Basin depths for slide installations shall comply with Table 390.31-1.
Except as permitted for wading pools in s. SPS 390.20
, the shallowest water depth of the shallow end of pools shall be a minimum of 30 inches and a maximum of 42 inches.
The water depth at the breakpoint in a combination pool shall be no less than 4.5 feet and no more than 5.5 feet.
(10) Vanishing edges.
A single vanishing edge basin wall occupying a maximum of 50% of the basin perimeter may be included within a water attraction when all of the following are included in the design:
The vanishing edge is located adjacent to water that is at least 5 feet deep.
A catch ledge, a minimum of 3 feet in width or equivalent protection, is included on the dry side of the basin wall.
The catch ledge shall be located outside of the basin within 3 feet vertically from the top of the basin wall.
The catch ledge shall be designed to prevent a patron from rolling off the catch ledge.
The catch ledge surface shall be constructed of materials that will not cause injury from abrasions or lacerations.
SPS 390.11 Note
See ch. SPS 390 Appendix
for further information on the design of vanishing edge basin walls.

SPS 390.12 Entries and exits, stairs, ladders, swimouts and benches. SPS 390.12(1)(1)
Entries and exits.
The minimum number, type and location of entries and exits shall be in accordance with Table 390.12-1.
a Travel to stairs is measured as the most direct path within the basin.
b Emergency exits may be permitted with written approval of the department.
Except as permitted in par. (b)
stairs, ladders, recessed treads and swimouts may serve as acceptable entries and exits.
Where the distance from the pool floor to deck surface is 24 inches or less, such areas shall be considered as providing their own natural mode for entry and exit.
Stairways shall be located only in areas of the basin with less than 5 feet of water depth.
Stairways shall be recessed so as not to protrude onto the basin floor.
All risers at the centerline shall have a maximum uniform height of 10 inches.
All treads shall have a minimum unobstructed surface area of 240 square inches.
Except as permitted in subd. 8.
, treads may not project beyond the face of the riser.
When stairways are located in a water depth over 4 feet, the lowest tread shall not be more than 4 feet below the deck.
The bottom riser height shall be allowed to vary from the other risers as may be required to meet the floor.
The leading edge of all steps shall be distinguished by a color contrasting with the color of the steps and pool floor.
Handrails shall be located between 30 and 34 inches above the ramp surface or nosing of the stair treads.
Handrails shall return to the pool wall, guard or deck or shall be continuous to the handrail of an adjacent stair.
