Building a Custom Spa Vault

The following can be used as a general guide to install a Bullfrog Spa in the ground. Before building the spa’s vault, please contact us for specific information regarding your spa dimensions and electrical requirements.

1- Excavate the Area

Select spa site, determine finished elevation and the direction the spa equipment will be facing. Ensure the surrounding surfaces will slope away from the spa.

2- Pour Foundation Walls

3- Rough-in Electrical and Drain Provisions

The conduit should be contained in the equipment access area which is located under the control panel. This is typically considered to be the front side of the spa.

4- Backfill Against the Foundation Walls

5- Pour the Concrete Spa Pad

The concrete slab should be at least 4″ thick.

6- Pour the Cement Cap

7- Install the Spa

At this point, you are ready for our crew to install the spa into the vault! Note our schedule typically requires two weeks of notice, so please coordinate this date between your contractors and our scheduling team.

8- Install Removable Decking Framework

Removable decking is necessary in case the spa ever needs to be serviced. This will provide the service technician with enough space to service the spa.

8A – Install cleats on all four sides of the foundation walls

8B- Build removable deck framing to sit on top of the cleats

9- Install Decking

10- Install Landscaping and Finish-Work

11- Install Cover and Cover Lifter to Decking

It is recommended when building a spa vault to purchase the Smart Top Upright cover for your spa. This cover is much stronger than the foam cover and will avoid breaking if accidentally walked or stepped on.
