An Installation Guide

Hot Tub Set-Up Basics

Site preparation is your responsibility.

Start with a Solid Foundation

Concrete Pad

If you install the spa outdoors, a reinforced concrete pad at least four inches thick is required for the Hot Spring Highlife Grandee® spa and the Limelight Gleam® model and recommended for all other Hot Spring Highlife, NXT, Limelight and Hot Spot models. When you select your hot tub, we’ll provide you with a pre-delivery guide with additional foundation information.

Concrete Pad Alternative

The SmartDeck creates an 8’X 8′ instant hot tub pad. It’s a great alternative to pouring concrete. Made of UV stable polymers, it comes in a slate gray that matches perfectly with outdoor landscaping. For all hot tubs except Hot Spring Highlife Grandee and Limelight Gleam. 

Pavers and Patio Installations

If you place the spa on the ground, even temporarily, place stepping stones (minimum 2’ thick X 12” square) under the leveling areas.

Even with stones in place, the spa will inevitably settle and become unleveled.

It is important to get it onto a solid foundation as soon as possible.

Note: Structural damage to the spa resulting from incorrect installation or placement on an inadequate foundation is not covered under the spa’s limited warranty.

Deck Installations 

To be certain your deck can support your spa,

  1. Find out the deck’s maximum load capacity. Consult a qualified building contractor or structural engineer before you place the spa on an elevated deck or indoors.
  1. Find the weight of your spa, its contents and occupants on the Specification Tab on the model page.

The spa’s weight per square foot must not exceed the structure’s rated capacity, or serious structural damage could result.

Electrical Requirements

  1. You’ll find electrical requirements for your hot tub under the Specifications Tab on model pages. Some are 110V plug-in, some require a 110V dedicated 20 AMP circuit and others are 220V hard-wired from your electrical panel box.
  1. Check the requirements for your model and have a licensed, bonded electrician
  1. If you purchase a 110V tub, in most cases you could get your electrical work completed prior to delivery. To minimize expense on 220V tubs, best to wait for the tub to be in position before the electrical is completed.

Need help finding an electrician? Ask your Olympic Hot Tub Sales rep who can recommend an electrician that we have worked with and knows our spas’ requirements.


Every hot tub we sell fills with a garden hose. A hose bib close to your spa is a good idea for convenience. Spa water that has been neutralized can be drained onto a lawn or flower bed area unless your city requires permanent drainage. Check local codes.
