The Complete Guide to Adding a Spa to Your Pool

Adding a spa to an existing pool is one of our most requested remodeling projects. It transforms a seasonal pool into a year-round retreat.

How We Do It

We typically build an attached spa within the existing footprint of the pool or adjacent to it. This involves plumbing integration, adding heating equipment, and electrical work.

Design Options

Most clients choose an elevated spa with a spillover effect. This creates a beautiful waterfall into the main pool and clearly separates the heated zone.

Equipment Upgrades

Adding a spa requires a dedicated heater (gas or heat pump) and often upgraded automation systems so you can turn on the heat from your smartphone before you even get home.
