PARTIALLY-RECESSED SPA PARTIALLY-RECESSED SPA
Drainage
There are two scenarios for a partially-recessed spa. The first is a spa that is recessed
into a raised deck, where the spa sits above grade on a cement pad. The second is a
spa that actually sits below grade and is surrounded by ground-level decking or a patio.
Scenario1:
Assumes that the spa is above grade. When selecting the location for your spa, ensure
that water will not puddle around the base of the spa. Consider a drainage system in
which the water flows down and away from the spa to an appropriate outlet or drain.
Scenario2:
Assumes that some portion of the spa is below grade. An installation below grade
requires careful planning. Since water flows downhill and water tables tend to rise, it’s
important to install your spa in a way that will protect it from rising water levels. At a
minimum, a drainage system should be installed. If you live in an area that is prone to
high water tables or flooding, a sump pump should be considered.
The optimal solution for this type of installation is a vault. Placing the spa in a vault will
allow access to all equipment and components. Access panels in the decking or patio
will be needed. The diagram below shows an example of a fully-recessed spa within a
vault; similar considerations are important for a partially-recessed spa.
Removal
It is best to plan for potential removal at the time of installation. There are a few options
to consider.
Option1:
Construct your partially-recessed patio or decking so that the entire front face of the
spa is exposed. This will allow movers to slide the spa out of the surrounding decking
or patio surface (also see concrete pad diagram).
Option2:
Construct a modular decking system that allows you to remove sections of your decking
to enable the spa to slide out (also see concrete pad diagram below).
Option 3:
If your spa is installed in a vault or your decking cannot be constructed to
accommodate removal, a crane can be used to remove the spa. In preparation
for removal, even if a crane is not required, it’s good practice to pour a concrete
pad with removal of the spa in mind. When planning the foundation for your spa,
lay two 2’ x 6’s in the wet concrete to form recesses as shown below. These
recesses create two strap slots. Straps can then be snaked underneath the
spa in the unlikely event that the spa must be completely removed for repairs.

NOTE: If the base of the spa is located either below an appropriate outlet/drain or in
a vault-type location, then a sump pump is necessary.
