A spool pool, often called a “spool” or cocktail pool, is a compact pool–spa hybrid designed to fit into smaller outdoor spaces while offering both relaxation and swim-against-the-current functionality. Typically measuring between 10 and 16 feet long and 6 to 8 feet wide, spools are ideal for urban backyards, rooftop terraces, and tight patios where a traditional pool would overwhelm the area. Rising in popularity, spool pools combine spa-like features—such as jet-driven currents, heated water, and integrated seating—with design elements like tanning ledges, waterfalls, and energy-efficient systems to maximize both enjoyment and usability.
1. Compact Rectangular Spool

A Compact Rectangular Spool leverages the classic pool shape in a smaller footprint, providing a familiar aesthetic with minimal space requirements. By keeping clean lines and right angles, this design integrates easily alongside decks and landscape beds without awkward transitions. Many homeowners choose fiberglass or prefabricated kits for this style, speeding up installation and ensuring uniform walls and floors. The rectangular form also simplifies adding swim jets for continuous exercise, enabling a lap-style swim in just a few strokes. A simple tile or aggregate finish completes the look, blending durability with modern appeal.
2. Swim-Jet Training Spool

Swim-Jet Training Spools incorporate powerful adjustable jets to generate a current, transforming the spool into a home hydro-gym. These jets can be calibrated for resistance levels, accommodating beginners and advanced swimmers alike without requiring a full-length lap pool. Builders often install dual jet outlets at opposite ends, allowing for bidirectional workouts and improved muscle engagement. A non-slip floor finish and recessed bench seating ensure safety and comfort during longer training sessions. Lighting beneath the waterline enhances visibility and ambiance for early-morning or evening exercise.
3. Heated Spa-Style Spool

Heated Spa-Style Spools blend the warmth of a hot tub with the depth and size of a pool, perfect for year-round relaxation. A high-efficiency heater circulates warm water, maintaining temperatures between 90°F and 104°F, turning the spool into a cozy retreat during cooler months.

Decorative mosaics or natural stone veneers can enrich the spa-like appearance and elevate the overall design.
4. Tanning-Ledge Spool

A Tanning-Ledge Spool adds a shallow shelf, typically 6–12 inches deep, along one side for sunbathing and lounging. This ledge accommodates chaise lounges, inflatable pads, or simply serves as a cool place to rest with feet immersed. The ledge’s gradual slope into deeper water appeals to families, offering a safe transition for children. Designers often pair the ledge with built-in umbrella mounts or pergolas for shade customization. Slip-resistant surfaces and rounded edges ensure user safety while complementing the spool’s clean aesthetic.
5. Rooftop Urban Spool

A Rooftop Urban Spool transforms flat roofs into exclusive leisure zones, maximizing unused overhead space.

Eco-friendly chemical systems such as saltwater chlorinators or ozone generators minimize harsh disinfectants.
7. Cocktail-Style Spool with Integrated Seating

Cocktail-Style Spools feature built-in benches or stools, allowing social gatherings directly in the water. Circular or rectangular benches are often contoured for ergonomic comfort during prolonged seating. A center table or recessed drink holders can be added to enhance the cocktail-party experience. Subtle perimeter lighting illuminates seat areas after dark without glare. Textured bench finishes prevent slipping while complementing the pool’s decor.
8. Infinity-Edge Spool

An Infinity-Edge Spool creates a seamless waterline that merges visually with the horizon or landscape beyond. The “vanishing” edge employs a narrow trough and hidden catch basin to recycle overflow water. This luxurious feature elevates small spaces with a high-end resort aesthetic. Glass tile liners or natural stone coping accentuate the infinity effect. Precision engineering ensures consistent water flow and prevents splashing.
9. Plunge-Pool Spool

A Plunge-Pool Spool emphasizes depth over length, often reaching 5–7 feet deep for quick, refreshing dips. This design supports hydrotherapy and shock cooling after workouts or sauna sessions. Narrow footprints make plunge spools ideal for narrow side yards or courtyard installations. LED spotlights and waterline tile reflect light to accentuate depth perception. Safety ladders or recessed steps provide secure entry and exit.
10. Glass-Wall Spool

A Glass-Wall Spool features transparent panels on one or more sides for striking visual effects. Tempered acrylic or laminated glass withstands water pressure while showcasing swimmers in action. The clear wall allows daylight to penetrate, reducing the need for artificial illumination. Surrounding the glass edge with tile or steel frames provides structural support and style. A hidden gutter system captures overflow to maintain the perfect waterline.
11. Wood-Clad Rustic Spool

A Wood-Clad Rustic Spool wraps the pool exterior in cedar, redwood, or composite decking for a warm, natural look. Vertical or horizontal plank arrangements create varying textures and patterns. To prevent rot, builders apply marine-grade sealants and use stainless-steel fasteners. Integrated bench seating made of matching wood enhances cohesion. Surrounding the spool with potted greenery reinforces the organic aesthetic.
12. Mosaic-Tile Luxury Spool

Mosaic-Tile Luxury Spools employ hand-cut glass or porcelain tiles to craft intricate patterns or murals on the pool floor and walls. Tile sizes ranging from 1×1 inch to 2×2 inches enable fine detailing. Accent bands or waterline borders in contrasting colors frame the design. Grout choices, including eco-friendly epoxy grouts, resist staining and fading. Proper surface preparation and waterproof backer boards ensure tile longevity.
13. Floating-Deck Spool

A Floating-Deck Spool incorporates a surrounding platform that appears to hover over the water’s edge. The deck is cantilevered from hidden supports, creating an illusion of floating. Materials like composite decking or Ipe hardwood resist moisture and splitting. Recessed lighting beneath the deck rim highlights the floating effect at night. Built-in storage benches keep pool essentials handy without visual clutter.
14. Fire-Pit Integration Spool

A Fire-Pit Integration Spool places a gas or wood-burning fire feature adjacent to or within the pool deck. This pairing fosters year-round use, providing warmth and ambiance in cooler evenings. Glass wind guards and stone surrounds ensure safety and durability. Designers often match deck materials between fire-pit and pool areas for seamless flow. LED uplighting highlights architectural elements after dusk.
15. Integrated Pool Bar Spool

An Integrated Pool Bar Spool features a swim-up bar counter with submerged seating. Bar stools anchored to the pool floor allow guests to enjoy drinks without leaving the water. A raised countertop on the pool deck accommodates bartending prep. Waterproof cabinetry and under-counter coolers keep refreshments chilled. Overhead pergolas or umbrellas provide shade and define the bar area.
16. Minimalist Concrete Spool

A Minimalist Concrete Spool uses clean, smooth shotcrete or gunite finishes for an ultra-modern look. Neutral color palettes—ranging from light gray to charcoal—enhance minimalist themes. Linear drains and hidden gutters uphold the sleek aesthetic. Polished concrete coping creates a refined edge and seating surface. Seamless integration with polished stone or aggregate decks completes the contemporary design.
17. Nature-Inspired Freeform Spool

A Nature-Inspired Freeform Spool emulates organic shapes, curving gently to mimic natural ponds. Rock scapes, boulder accents, and pebble finishes reinforce a wilderness vibe.
