Frequently Asked Questions

What is the water depth of Aspen’s tanning ledge?

Aspen’s tanning ledge gives you a true shallow-water lounge zone. Depending on your water level, in a full Aspen you’ll enjoy 6 to 8 inches of water depth in the 12-inch-deep tanning ledge area. It’s ideal for sunbathing, cooling off, and supervising little swimmers without committing to full pool depth.

How many chairs fit on Aspen’s tanning ledge?

The Aspen tanning ledge fits two chairs comfortably. You get a dedicated spot for relaxing in Ledge Loungers® or similar seating while still keeping entry and movement through the shallow area easy and natural.

What are Aspen’s exact dimensions?

Thursday Pools’ Aspen design comes in five unique size options so you can match your yard and your lifestyle. Here are the exact outside dimensions (O.D.) and inside dimensions (I.D.) for each model:

O.D. 12’ x 25′ 5’1″ | I.D. 11′ x 24’6″ 5’1”
O.D. 14’ x 30′ 5’5″ | I.D. 13’11” x 29′ 5’5”
O.D. 14’ x 35′ 5’5″ | I.D. 13′ x 34′ 5’5”
O.D. 16’ x 35′ 5’5″ | I.D. 14’11” x 34′ 5’5”
O.D. 16’ x 40′ 5’10” | I.D. 14’11” x 39′ 5’10”

How many gallons of water does Aspen hold?

Water volume changes by pool size. Here are the gallon capacities for each Aspen model:

12’ x 25’: 7,425 gallons
14’ x 30’: 7,610 gallons
14’ x 35’: 8,423 gallons
16’ x 35’: 10,140 gallons
16’ x 40’: 13,090 gallons

Does Aspen include a perimeter courtesy ledge?

Aspen does include a perimeter courtesy ledge around the deep end, located 48 inches from the top of the pool. The ledge gives swimmers an easy place to pause, reposition, or rest along the edge during social pool time or when they need a quick break.

Does Aspen support using an automatic pool cover?

The Aspen’s rectangular shape makes it a strong match for automatic pool covers because straight edges support clean track alignment. An automatic cover can boost safety, reduce debris, help retain heat, and cut evaporation so you spend more time enjoying your pool and less time managing it.

Does Aspen support lap swimming?

Aspen’s wide-open swim lane makes laps feel natural and consistent. You can swim, float, and train without weaving around tight curves. If you love fitness-focused pool time, Aspen delivers structure that helps you keep a rhythm.

Does Aspen include built-in seating?

In addition to the tanning ledge area and built-in stairs where swimmers can sit and rest, Aspen also includes integrated bench seating that creates an easy place to gather, relax, and stay connected. You can sit in the water, supervise swimmers, or take a break between laps without leaving the pool.

How do I choose the right Aspen size for my backyard?

Begin with how you want to use your pool. Choose a smaller Aspen size if you want a sleek rectangle pool that preserves patio and outdoor living space. Choose a larger size if you want more room for swimming, hosting, and everyday hangouts. Your local Thursday Pools dealer can help you match the right Aspen footprint to your yard access, layout, and lifestyle goals.

Rectangle Fiberglass Pools

Rectangle Fiberglass Pools Built for YOUR Life

A rectangle fiberglass pool is a pre-molded, single-piece fiberglass pool with straight walls and clean corners—ideal for lap swimming, modern backyard design, and automatic safety covers. Thursday Pools reimagines the classic rectangle with innovative features and built-in comfort options designed for relaxing, fitness, and connection. As one of the most popular pool shapes, rectangles offer timeless appeal and practical functionality.

The Benefits of Choosing a Rectangle Fiberglass Pool

Ideal for Lap Swimming & Fitness

Straight edges create uninterrupted swim lanes, making it easy to add a swim jet system or stick to a consistent workout routine.

Compatible with Automatic Pool Covers

The straight track system fits cleanly on rectangular pools, improving safety, retaining heat, and cutting energy costs.

Efficient Use of Space

Rectangle pools align naturally along fences, homes, and patios, making them a smart choice for narrow or smaller backyards.

Timeless Style

Clean lines work with both modern and traditional architecture, so a rectangle pool looks at home in almost any backyard.

Built for How You Use It

Choose from tanning ledges, integrated benches, zero-entry options, swim-out benches, or varied depth configurations depending on how you plan to use your pool.

RECTANGLE VS. FREEFORM VS. ROMAN FIBERGLASS POOLS

Each pool shape creates a different backyard feel and supports different priorities. A rectangular fiberglass pool gives your backyard a clean, open look that pairs beautifully with almost any style of home. Its classic lines feel as natural beside a modern patio as they do in a traditional backyard.

A freeform fiberglass pool features soft curves that blend into gardens and landscaping, creating a backyard that feels like an outdoor escape. A Roman fiberglass pool combines straight sides with gently rounded ends, giving your backyard a classical, architectural elegance.

Choose a Rectangle Pool if You:

Want the maximum length lap-swimming lane
Plan to install an automatic pool cover
Prefer modern or minimalist architectural design
Have a narrow backyard layout
Want clean patio alignment and defined edges

Choose a Freeform Pool if You:

Prefer soft, natural curves
Want a lagoon-inspired aesthetic
Plan to incorporate rock features or tropical landscaping
Care more about organic appearance than swim space
Want lounging zones that feel organic and social

Choose a Roman Pool if You:

Love timeless symmetry with softened, elegant ends
Want a classic focal point that feels refined and inviting
Prefer curved built-in seating for gathering and relaxing
Want straight sides without sharp corners
You value visual balance and architectural appeal

Choosing a Rectangular Pool Size

Before choosing a specific rectangle fiberglass pool model, understand which size fits your yard and how you plan to use it. Size impacts budget, patio space, swim function, and overall backyard flow.

Sea Turtle in California Finish

Small Rectangle Plunge Pools

8'4" x 16’ to 12’ x 25’

Small rectangle fiberglass pools are ideal when yard space is limited or when you want the pool to complement your outdoor living area instead of dominate it. Benefits of small rectangle pools include:

• Plunge pool style living

• Cooling off and relaxing

• Light exercise

• Preserving space for patio, turf, or outdoor kitchens

Aspen | Diamond Finish

Medium Pools Most Popular for Families

13.5' x 28' to 14' x 36'

Medium rectangle pools offer the most flexibility for everyday use. They provide enough length for laps and games while still leaving room for landscaping and gathering areas in a standard-size (roughly 8,400 sq ft) lot. Benefits of a medium rectangle pool include:

• Lap swimming without a full competition length

• Room for pool games and open swim areas for kids and guests

• A balanced backyard layout with space remaining for patio, turf, or outdoor kitchens

Monolith | California Finish

Large Pools for Diving, Hosting & Entertaining

13.5' x 35' to 16' x 41'

Large rectangle pools are best suited for homeowners who want swimming distance and gathering capacity to be the priority in their backyard design. In some instances, this size shifts the yard’s focus toward the pool itself rather than surrounding lawn space or secondary features.

• Capacity for larger groups without the pool feeling crowded

• Clear separation between shallow lounging areas and active swim space

• Strong visual proportion in wider or deeper backyards

Frequently Asked Rectangle Fiberglass Pool Questions

How much does a rectangular fiberglass pool installation cost?

Most fiberglass pool installations range between $30,000 and $85,000 or more, depending on pool size, features, delivery distance, site access, and regional labor costs. Larger rectangle pools, added features, automatic covers, upgraded decking, and complex excavation conditions can increase the necessary investment. Your backyard layout and design goals ultimately determine final pricing. For a full breakdown of fiberglass pool installation costs, see our Fiberglass Pool Cost Guide. Financing is also available from certain lenders for those interested in financing their pool project.

What affects the price of a rectangular pool?

Pool length and depth profile drive cost first. Site access, soil conditions, elevation changes, decking choices, water features, and automatic pool covers also influence pricing.

What’s the difference between rectangle pools and freeform pools?

Rectangle pools emphasize clean lines, lap-friendly swim lanes, and modern symmetry. Freeform pools create a softer, more organic backyard feel. If you value clean lines, swim efficiency, and automatic cover compatibility, rectangle often wins. Many homeowners also choose a rectangle fiberglass pool for a small backyard. If you prefer natural curves and a lagoon aesthetic, freeform may suit you better.

Are rectangular pools better with a flat bottom or a deep end?

Choose a flat-bottom rectangle pool if you plan to play games, exercise, or enjoy social standing depth. Select a deep-end design if you prefer more vertical swim space, floating freedom, or diving capability in approved models. Your intended use should guide this decision.

Should I prioritize a tanning ledge or open swim space?

If relaxation ranks first, choose a tanning ledge for shallow lounging and sunbathing. If activity and exercise matter more, prioritize open swim length. Many rectangle fiberglass pool designs balance both, giving you space to lounge and move.

How long does it take to install a fiberglass rectangle pool?

Fiberglass pools arrive as single-piece shells manufactured in a controlled environment. Your installer excavates, sets the shell, connects plumbing, and completes backfill and decking. Many projects finish within a few weeks under normal conditions, depending on weather and site complexity.
