Frequently Asked Questions

How Many Gallons Does a Wellspring Hold?

The 16-foot-by-36-foot Wellspring holds approximately 13,500 gallons. The 16-foot-by-40-foot model holds approximately 15,500 gallons.

What Are the Exact Dimensions of the Wellspring?

The smaller Wellspring measures 16 feet by 36 feet outside and 15 feet by 35 feet inside. The larger model measures 16 feet by 40 feet outside and 15 feet by 39 feet inside. Both sizes have a maximum depth of 5 feet 10 inches.

Does the Wellspring Have a Courtesy Ledge?

No. A courtesy ledge runs along part of a pool’s deeper perimeter and gives swimmers a place to stand and rest. The Wellspring offers a deep-end bench instead, providing a comfortable seat where swimmers can pause without leaving the water.

Can the Wellspring Accommodate an Automatic Pool Cover?

An automatic pool cover may be possible for the Wellspring, but its freeform shape typically requires a system with tracks installed along the top of the pool deck. Discuss the cover with your local dealer early so it can be considered when planning the pool and surrounding patio.

How Do I Choose the Right Wellspring Size?

Begin with the available space in your yard. The 16-foot-by-40-foot Wellspring provides more open swimming room, while the 16-foot-by-36-foot model fits a shorter area without sacrificing the design’s sun shelf, benches, or entry steps. A local dealer can help you compare both sizes with your property and plans for the pool.

How Many Chairs Fit on the Sun Shelf? Is It the Same as a Tanning Ledge?

Yes. “Sun shelf” and “tanning ledge” describe the same shallow-water feature. The Wellspring’s 8-foot-diameter sun shelf fits two ledge loungers with space between them.

Bob’s done it again, only even bigger. Big Bob gives everything that made Lil Bob a fan favorite the room it deserves: a 16′ x 40′ flat-bottom rectangle fiberglass pool with extra-long built-in benches on both sides and wide walk-in entry steps. Swim laps, play games, and float all afternoon with plenty of bench space left over for the whole crew. Bob’s always been a good sport. Now he’s got the pool to show for it.

Frequently Asked Questions

What are the dimensions of the Big Bob pool?

Big Bob comes in one size with outside dimensions of 16′ x 40′, inside dimensions of 15′ x 39,’ and a depth of 4’6″. It’s the largest pool in the Bob family, offering more width and length than the Lil Bob LX while keeping the same beloved flat-bottom design. Contact your local Thursday Pools dealer to confirm excavation requirements for your specific yard.

How deep is the Big Bob pool?

Big Bob has a uniform flat-bottom depth of 4’6″ throughout the main swim area. That standing depth is ideal for water games, family play, and recreational swimming, and it means guests of all ages can comfortably touch the bottom and enjoy the full pool.

Does Big Bob have a flat bottom?

Yes. Like its siblings Lil Bob and Lil Bob LX, Big Bob features a uniform flat-bottom design from end to end. There’s no deep end to worry about, which makes it exceptionally family-friendly and well-suited for water sports, games, and safe, active play for all ages.

Does Big Bob have built-in bench seating?

Yes, and then some. Big Bob features extra-long built-in benches running down both sides of the pool, giving families and guests plenty of spots to sit, cool off, and stay in the action without leaving the water. The benches are finished with Thursday Pools’ non-skid gel coat surface, which is easy on skin, swimsuits, and bare feet.

Is the Big Bob pool good for water volleyball or other water sports?

Absolutely. The flat-bottom design and generous 16′ x 40′ swim area make Big Bob a natural fit for water volleyball, basketball, and virtually any pool game you can dream up. If your family loves active, game-centered pool time, Big Bob delivers the space to make it happen and still leaves room for everyone else to float.

Does Big Bob support using an automatic pool cover?

Big Bob’s rectangular shape is well-suited for automatic pool covers, which track cleanly along straight edges. An automatic cover improves safety, reduces debris, retains heat, and cuts down on evaporation, which means less maintenance and more time in the water.

How does Big Bob compare to Lil Bob and Lil Bob LX?

All three pools share the same core design DNA: flat bottom, built-in benches on both sides and wide walk-in steps. Lil Bob (13.5′ x 27.5′) is the most compact of the three, built for sporty fun in a smaller footprint. Lil Bob LX (13.5′ x 35.5′) adds a wading area for younger swimmers. Big Bob (16′ x 40′) takes everything a step further with more width, more length, even longer benches, and the most open swim space of the family. The extra room makes it the right choice for larger households, frequent entertainers, and anyone who simply wants the most Bob has to offer.

What size backyard does Big Bob require?

With outside dimensions of 16′ x 40′, Big Bob is best in larger backyards that can accommodate the pool footprint plus the surrounding deck, patio, and required setbacks from property lines and structures. Your local Thursday Pools dealer can help you evaluate your yard layout and confirm whether Big Bob is the right fit for your space.

Frequently Asked Questions

What’s the difference between Cathedral and Cathedral LX?

The Cathedral LX keeps the classic Greco-Roman style of the original Cathedral design, but adds a 9-foot-diameter tanning ledge flanked by two sets of entry steps. The added shallow lounging space gives Cathedral LX a more relaxation-forward layout while preserving the timeless symmetry that defines the shape.

What is the water depth of Cathedral LX’s tanning ledge?

The Cathedral LX tanning ledge has a 12-inch depth, which typically gives you about 6 to 8 inches of water depending on your fill level. That shallow-water zone creates an easy place to lounge, cool off, and enjoy the water without stepping into the main swim area right away.

How many chairs fit on Cathedral LX’s tanning ledge?

The Cathedral LX features a 9-foot-diameter circular tanning ledge that fits two chairs or Ledge Lounger® chaises comfortably. You still get smooth movement through the shallow end thanks to the surrounding entry steps that frame the ledge.

What are Cathedral LX’s exact dimensions?

Thursday Pools offers the Cathedral LX in two size options. Here are the outside dimensions and inside dimensions for each model:

O.D. 16’ x 36’ 5’8″ | I.D. 15’ x 35’ 5’8”
O.D. 16’ x 40’ 6′ | I.D. 15’ x 39’ 6′

How many gallons of water does Cathedral LX hold?

Water volume depends on the size you choose. Here are the gallon capacities for each Cathedral LX model:

16’ x 36’: 10,500 gallons
16’ x 40’: 12,500 gallons

Does Cathedral LX support using an automatic pool cover?

Yes, Cathedral LX is auto-cover-ready. Automatic pool covers help improve safety, keep debris out, retain heat, and lower maintenance demands, making them a strong fit for many fiberglass inground pool owners.

Roman Fiberglass Pools

ROMAN POOLS BRING CLASSIC ELEGANCE HOME

A Roman fiberglass pool combines straight sides with softly rounded ends, drawing on the timeless symmetry of ancient bath design to create a shape that feels both refined and welcoming. Among the fiberglass pool shapes Thursday Pools offers, Roman pools stand out for homeowners prioritizing easy conversation, relaxed lounging, and everyday swimming.

THE BENEFITS OF CHOOSING A ROMAN FIBERGLASS POOL

Timeless Style with Softer Curves

Roman pools bring symmetry and structure, then soften the look with rounded ends that add warmth and classic appeal.

Space-Efficient Shape That Still Feels Grand

Straight sides help you use backyard space wisely, especially in narrower layouts, while the domed ends create a distinctive focal point.

Designed for Comfort and Connection

Wide steps and built-in seating make Roman pools feel social and welcoming for lingering conversations or laid-back afternoons.

Elegant Backyard Versatility

Roman pools complement modern landscaping and traditional architecture. They can anchor a formal layout or elevate a relaxed outdoor retreat.

Fiberglass Makes Roman Luxury More Attainable

Roman shapes can cost more in other pool types due to custom craftsmanship. Fiberglass delivers the same timeless design in a one-piece shell built for long-lasting performance.

ROMAN VS. RECTANGLE VS. FREEFORM POOLS

Each pool shape creates a different backyard feel and supports different priorities. A Roman fiberglass pool blends classic symmetry with rounded ends for a softer, more architectural look. You get the efficiency of straight sides plus a timeless design that feels elevated and inviting.

A rectangular fiberglass pool leans fully into straight lines and swim performance. It suits lap swimmers, modern design lovers, and homeowners who want the cleanest layout for patios and automatic pool covers. A freeform fiberglass pool brings organic curves and a relaxed, nature-inspired vibe. It flows beautifully with landscaping and creates a resort feel that feels playful, peaceful, or both.

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

Choose a Rectangle Pool if You:

Want a clear lap-swimming lane
Plan to install an automatic pool cover
Prefer modern, structured design lines
Want defined edges for patio alignment
Prioritize swim efficiency and symmetry

Choose a Freeform Pool if You:

Want a softer, more natural backyard vibe
Love curves that complement landscaping and patios
Prefer a relaxed, resort-inspired look
Care more about atmosphere than strict swim symmetry
Want lounging zones that feel organic and social

CHOOSING A ROMAN POOL SIZE

Before you choose a Roman pool design and size, think about how you want your pool to feel day to day, from lap space to lounging space, and how much patio or landscaping you want to keep around it.

Cathedral | California Finish

Medium Roman Pools

14’ x 33’

Medium Roman pools offer comfortable swim space and room to gather without dominating a standard-size lot. The proportions work well for everyday family use, entertaining, and backyards where you want the pool to anchor the space without taking over. Benefits of a medium Roman pool include:

• Comfortable swim and gathering space
• Strong proportion on standard backyard lots
• Room for entertaining without crowding the yard
• Suits both active swimming and relaxed lounging

Cathedral LX | California Finish

Large Roman Pools

16' X 36' to 16’ x 40’

Large Roman pools are best suited for homeowners who want the pool to be the centerpiece of the backyard with room to match. The longer swim corridor and wider footprint support bigger gatherings and give the shape the space it needs to make a full impression. Benefits of a large Roman pool include:

• More swim distance and gathering capacity
• Clear separation between lounging and active swim zones
• Acts as a dramatic centerpiece for wider or deeper yards
• Room to build a full outdoor destination around it

FREQUENTLY ASKED ROMAN FIBERGLASS POOL QUESTIONS

HOW MUCH DOES A ROMAN 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. 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 ROMAN POOL?

Pool size and depth profile drive cost first. Yard access, excavation conditions, retaining walls, decking design, water features, and landscaping plans also influence pricing.

WHAT MAKES A ROMAN POOL DIFFERENT FROM A RECTANGULAR POOL?

Roman pools keep straight sides for efficient use of space, then add rounded ends for a softer, more classic look. Rectangle pools stay fully linear and often prioritize lap swimming lanes and automatic cover compatibility.

DO ROMAN POOLS COME WITH TANNING LEDGES OR SHALLOW LOUNGING AREAS?

Thursday Pools’ Cathedral LX design includes a large, luxurious tanning ledge that makes relaxation a main feature.

WHAT DOES A ROMAN FIBERGLASS POOL INSTALLATION LOOK LIKE?

Your installer excavates, sets the one-piece fiberglass shell, connects plumbing, and completes backfill and decking. Most projects wrap within a few weeks under normal conditions, depending on weather and site complexity.

DO ROMAN POOLS WORK WELL IN NARROW YARDS?

With straight lines along its two long sides, Roman pools align well along fences, patios, and property lines of narrow backyards. The rounded ends add style without sacrificing the space efficiency of straight sides.

ARE ROMAN POOLS HARDER TO MAINTAIN BECAUSE OF CURVED ENDS?

Roman pools can collect debris in curved areas and steps, so regular brushing in those zones helps keep everything clean. Fiberglass surfaces inherently support easier cleaning and resist algae buildup, which makes routine care simpler overall.

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.

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.

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

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

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

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.
