In this blog, we’ve rounded up 10 of the most beautiful and functional rectangle swimming pool ideas for all types of homes—from minimalist retreats to resort-style escapes. Discover the latest rectangle pool trends, smart features, and must-have landscaping styles to inspire your perfect backyard transformation.
1. Modern Minimalist Rectangle Pool Design
The minimalist movement is showing no signs of slowing down in 2025, especially when it comes to backyard transformations. Modern rectangle pool design is all about clean geometry, refined materials, and functional elegance. Think polished concrete decks, light gray or white travertine pavers, and sleek waterline tiles in muted tones.
Homeowners are favoring concrete rectangle pools with fully tiled interiors for a crisp, modern look. Add automated pool covers, flush-edge coping, and minimalist landscaping with ornamental grasses, black mulch, and sculptural trees to complete the aesthetic. In-wall LED lighting, remote-controlled jets, and in-pool bar stools add subtle luxury.
2. Rectangle Pool with Tanning Ledge & Baja Shelf
2025 pool lovers are swooning over rectangle pools with tanning ledges. These shallow platforms (also known as Baja shelves) allow for partial submersion—perfect for lounging, reading, or even toddler play. This feature blends style and function and has become a must-have in luxury rectangle pool design.
Popular add-ons include umbrella sleeves, built-in chaise lounges, and even bubbler fountains. The integration of this shallow zone with the deeper swimming area creates an elegant transition in resort-style backyard pools.
3. Infinity Edge Rectangle Pool (Vanishing Edge Pool)
Want the backyard to feel endless? A rectangle infinity edge pool (aka vanishing edge pool) is perfect for sloped properties or homes with scenic views. The water flows over one or more edges, creating an illusion that the pool merges with the landscape.
These designs pair well with glass walls, hidden trough catch basins, and modern outdoor tiles. Ideal for luxury properties in coastal, hillside, or forested areas, this design adds value, drama, and serenity.
4. Rectangle Plunge Pool for Small Backyards
Not everyone has acres of land, and that’s where the rectangle plunge pool shines. Perfect for urban settings and compact outdoor spaces, these pools are deep, stylish, and refreshingly low-maintenance.
Despite their smaller footprint, these pools often include heated plunge features, spa jets, and bench seating. Pair with vertical gardens, deck-mounted fire bowls, and compact outdoor kitchens for a complete small-space resort.
5. Lap Pool Design in Rectangle Shape
For fitness-forward homeowners, the rectangle lap pool is a dream. These pools are typically long and narrow, designed for uninterrupted laps. With rising interest in home wellness, lap pools are more popular than ever.
You can opt for fiberglass lap pools, gunite with tile lanes, or even modular lap pool kits. Add underwater lighting and swim resistance systems to enhance your aquatic workout.
6. Rectangle Pool with Integrated Spa
Why settle for just a pool? Combine relaxation and recreation with a rectangle pool and spa combo. Whether you opt for an integrated spa inside the pool or an adjoining hot tub, this dual-feature design is making waves in 2025.
LED-lit waterfalls, fire-and-water features, and spillover spas are among the most sought-after touches. This combo brings a spa-like feel right to your backyard retreat.

7. Rectangle Pool with Dark Bottom Finish
Make a bold statement with a dark bottom rectangle pool. Deep charcoal, navy, and even black finishes are trending for their reflective qualities and natural heat retention. These finishes mimic the appearance of lagoons or luxury resorts.
Pair with natural stone coping, matte black fixtures, and tropical landscaping for dramatic flair. Just be sure your pool pro understands depth visibility and safety codes.
8. Rectangle Pool with Glass Walls
Few things scream “wow” like a glass wall rectangle pool. Whether it’s a see-through side wall or underwater window, this architectural feature is making high-end waves in both residential and commercial projects.
Best suited for sloped yards, multi-level patios, or indoor-outdoor pool designs, glass walls blend engineering and artistry. Expect tempered glass, reinforced steel frames, and lots of envy from guests.
9. Rectangle Pool with Smart Tech Integration
Say hello to the smart rectangle pool of 2025. Automated systems control lighting, temperature, chlorination, and water features from your smartphone. Add voice controls via Alexa or Google Home for the ultimate luxury.
Integrate with solar pool heating, robotic cleaners, and AI-based water level sensors. The smart pool revolution is all about energy efficiency, convenience, and real-time control.
10. Rectangle Pool with Outdoor Living Integration
In 2025, pools aren’t standalone features—they’re central to your outdoor living space. Combine your rectangle pool with sunken lounges, outdoor kitchens, fire pits, and luxury cabanas.
Create a seamless transition from pool to patio using matching decking, coordinated color palettes, and retractable shade systems. These integrated designs offer an elevated backyard lifestyle.
