Custom Spool Design
Compact pool-and-spa hybrids for smaller Scottsdale backyards.
Introduction
A spool is a pool sized like a spa — usually 10 to 16 feet long, three to five feet deep, with built-in seating and water features. Common in Scottsdale lots where a full pool would crowd the yard.
What This Solves
Smaller Scottsdale and Paradise Valley properties — and many newer infill builds — do not have the square footage for a 30-foot pool. A spool fits where a pool will not, without the cramped feel of a hot tub.
Our Approach
- Property review to confirm setbacks, drainage, and the best location for water.
- Spool design with seating, water features, and integration with surrounding deck and shade.
- Engineered as a pool — not a spa — so the structure, plumbing, and finish read luxury.
- Heating and circulation sized for year-round Arizona use.
What's Included

Frequently Asked Questions
How is a spool different from a hot tub?
A spool is built as a pool — gunite shell, full tile, custom shape — and connected to a pool-grade equipment pad. A hot tub is a portable unit on a pad.
Can a spool be used year-round?
Yes. With a properly sized heater, a spool stays usable through Scottsdale winters.
Is the cost of a spool less than a full pool?
Usually yes, because the volume is smaller. Finish and features still drive cost, so a high-end spool can approach the price of a basic full pool.
What size yard do I need?
Most spools fit comfortably in a 400 to 600 square foot footprint including deck.
Do spools work with fire features?
Yes. Fire bowls, fire walls, and raised water elements are common spool features.
