A Custom Spa, Built To Match Your Backyard

A drop-in hot tub sits in the corner and looks like an afterthought. An integrated gunite spa becomes part of the design, sharing the pool's finish, tile, and coping, with a spillover that doubles as a water feature. Stone Pools builds custom spas as part of a new pool or adds them to an existing one throughout the Austin area.

Because our spas are built in place from the same shotcrete shell as our pools, they last for decades and can be shaped, raised, or sized however the space calls for. Add a powerful heater and smart controls and it is ready year-round, even on a cool Central Texas evening.

What's Included in a Custom Spa

Every integrated spa is a complete, engineered system:

  • Custom gunite spa shell
  • Matching interior finish and tile
  • Spillover into the pool
  • High-output heater
  • Therapy jets and blower
  • LED lighting
  • Smart automation and app control
  • Coping and seating to match

Finishes and Materials We Build With

Your spa can match the pool exactly or stand out as a feature. Options include:

  • Quartz and pebble interiors
  • Glass and stone spillover tile
  • Raised or flush designs
  • Travertine and stone coping
  • Bench and lounge seating
  • Fire features on the spa wall

What Affects Spa Price

Spa cost depends on how it's built and equipped:

  • New build vs added to an existing pool
  • Size and number of seats
  • Raised vs flush design
  • Heater size
  • Jets, blower, and automation
  • Tile and finish grade
  • Fire or water features

Spa Styles We Build

The spa designs Austin homeowners ask for most.

Raised Spillover Spa

A classic raised spa that spills into the pool, adding sound, movement, and a focal point.

Flush Spa

A spa set level with the pool and deck for a clean, modern, seamless look.

Spa & Fire

Pair the spa wall with a fire bowl or linear fire feature for year-round ambiance.

Standalone Spa

A custom in-ground spa without a pool, perfect for smaller yards.

Therapy Spa

Extra jets and ergonomic seating tuned for real hydrotherapy.

Swim Spa Alternative

A larger spa sized for both relaxation and gentle exercise.

Year-Round Spa Living in Central Texas

Austin's mild winters mean a heated spa gets used almost every month of the year. We build spas across the metro, from central Austin to Lakeway and the Hill Country, sized and heated for real year-round use.

Adding a spa to an existing pool takes care to match the original finish and tie into the plumbing and controls cleanly. Our crews do this all the time, so the result looks original, not bolted on.
