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.

Best Pool Financing Companies for Fiberglass Pool Projects

If you’re comparing pool financing companies, you’re probably trying to answer the practical question of which lender or financing path makes the most sense for your project, your budget, and your timeline. This guide breaks down several common options homeowners consider, including specialty pool loan companies, general lenders, and home equity routes, so you can compare them with clearer expectations. Thursday Pools does not endorse one lender over another.

 

What to Look for in Pool Loan Companies

Before you compare lenders, it helps to understand the size of the project you may be financing. Many turnkey fiberglass pool projects fall within the $70,000 to $135,000 range, depending on size, access, geography, and extras. The right lender for your installation must have the right loan structure, funding process, and repayment terms for the full scope of the project.

 

Some companies that finance pools focus on unsecured loans. Others connect you to staged funding, builder-direct payments, or multiple loan options from lending partners. A few key questions can help narrow the field for your purposes fast:

 

  • Do you want to avoid borrowing against your home?
  • Do you need one lump sum or staged payments during construction?
  • Do you care more about lower monthly payments or lower total interest?
  • Do you have strong home equity, or would an unsecured option fit better?

 

Your financing choice often comes down to three things: how large the full project is, whether you want to borrow against home equity, and what payment range feels comfortable month to month.

 

Lyon Financial vs. HFS Financial for Pool Financing

Lyon Financial and HFS Financial both show up often in conversations about the best pool financing companies, but they structure their offers and products a little differently.

 

Lyon Financial focuses heavily on swimming pool lending, offering nationwide pool loans up to $200,000, terms up to 30 years, and builder-direct staged payments that the borrower approves during construction. The builder-payment model can appeal to homeowners who want funding to track the project schedule instead of receiving one lump sum upfront. Lyon also emphasizes unsecured options, which means no home equity requirement for many borrowers.

 

HFS Financial also focuses on pool and home improvement lending while emphasizing fixed-rate personal loans, no prepayment penalties, no home equity requirement, and terms from 1 to 20 years. HFS says it offers loan amounts from $5,000 to $300,000 on some programs and highlights direct-to-consumer funding, which gives homeowners more control over how they pay for the pool and related work. Homeowners can check prequalification through HFS without a hard credit pull.

 

Lyon may appeal more if you’d like staged builder payments and longer terms, while HFS may be more appealing if you want a fixed-rate unsecured loan with direct borrower control over funds. The right fit depends on how you want the money to move during your project. 

 

LightStream and Other Lenders for Pool Loans

LightStream sits a little differently among pool lenders because it doesn’t focus only on pools. It offers unsecured loans for many types of projects. Swimming pool loan terms range from 24 to 240 months, and approved borrowers can get access to financing funds quickly.

 

That setup fits borrowers who want speed, a clean online process, and a lender that treats the pool as one type of home project rather than a specialized category.

 

LightStream works best for borrowers who want a fast, fully online process and do not need construction-stage draw payments tied to the builder schedule. The potential tradeoff is that general home-improvement lenders may not build their disbursement process around pool construction in the same way some pool-specific lenders do. 

 

Viking Capital and Dealer-Connected Pool Loan Lenders

Viking Capital works differently from other pool financing companies by acting more like a consultant than a direct lender. Viking works with pool builders and financing partners to match borrowers with loan options that fit their project and credit profile.

 

With one application and a soft credit pull, borrowers can review options before committing. Viking offers unsecured loan terms up to 20 years for projects that typically start around $25,000, with up to 100% financing available on some pool builds. It also uses a draw schedule that sends payments directly to the builder as the project moves forward instead of releasing one lump sum at closing.

 

Viking’s structure may appeal to homeowners who want financing tied more closely to construction progress. The tradeoff is transparency, as rates are not published upfront. They are disclosed during the consultation process based on your credit profile and loan structure. Ask for the full term sheet, including rate, fees, repayment term, and disbursement schedule.

 

Swimming Pool Financing Companies vs. Home Equity Options

Not every buyer ends up using specialized swimming pool financing companies. Some choose a home equity loan or home equity line of credit (HELOC) through a bank or credit union instead.

 

The choice usually comes down to a simple tradeoff. Home equity products may offer lower rates, but they take longer, involve more paperwork, and use your home as collateral. Specialized pool loan companies may move faster and offer unsecured loans, but the rates can run higher. If speed matters most, lender-direct or dealer-connected pool financing may win out for you. If long-term borrowing cost matters most, home equity deserves a close look.

 

How to Compare the Best Pool Financing Companies

Advertised rates only tell you part of the story. Before you choose between pool financing companies, compare:

  • Maximum loan amount
  • Loan term length
  • Fixed vs. variable rate
  • Unsecured vs. home-secured structure
  • Staged payments vs. lump-sum funding
  • Prepayment penalties
  • Speed to approval and funding

 

Because many fiberglass pool projects fall in the $70,000 to $135,000 range, lender fit matters just as much as headline pricing. A lender that works well for a smaller home project may not work as well for a larger pool-and-patio budget. Some lenders let you check prequalification without a hard credit pull. HFS allows you to check if you’re prequalified without impacting your credit.

 

Compare Your Pool Financing Options Before You Apply

Before you choose between pool financing companies, run the math on the full project. Try out the Thursday Pools Financing Calculator to estimate possible payments based on loan amount, rate, and term. Then connect with a local independent dealer to talk through your pool plans, site conditions, and the financing paths that make the most sense for your budget. 

 

Frequently Asked Questions About Pool Financing Companies

 

What companies offer financing for swimming pools?

  • Several known pool financing companies and lenders offer options for swimming pools, including:
    • Lyon Financial
    • HFS Financial
    • LightStream
    • Viking Capital
  • Some buyers also use home equity loans or HELOCs through banks and credit unions. The biggest difference is that some lenders specialize in pools, while others offer broader home-improvement loans that can be used for pool projects.

 

What credit score do you need for pool financing?

  • Requirements vary, but many lenders prefer scores in the 680 to 700 range or higher. Some programs may work with borrowers in the mid-600s, especially if the overall credit profile is strong. Better credit usually improves both approval odds and pricing. 

 

How much can you finance for a swimming pool?

  • Loan amounts vary by lender, income, credit, and project type, ranging from about $20,000 on the low end to $200,000 or $300,000 on some programs. Try the Thursday Pools Financing Calculator to test various payment scenarios before you apply.

 

Is it better to finance a pool through a lender or home equity?

  • Pool lenders often move faster and may offer unsecured loans, which means you do not have to borrow against your home. Home equity loans and HELOCs often offer lower rates, but they usually take longer and require sufficient home equity. The better option depends on whether you value speed, lower rates, or keeping your home out of the financing structure.

Pool Financing Options: How to Choose the Right Path for Your Fiberglass Pool

Cathedral LX fiberglass pool in Diamond finishIf you’re researching pool financing options, you’re probably asking a practical question, not a dreamy one: How do I make this work without stretching my budget too far? That’s exactly where smart pool financing starts. Most homeowners do not pay for a fiberglass pool one way alone. They compare options, weigh tradeoffs, and choose the path that fits their savings, equity, timeline, and comfort with monthly payments.

How to Finance a Pool: Start With the Full Project Budget

Before you compare pool financing options, get clear on the total project. Fiberglass pool pricing depends on pool size, site conditions, access, geography, patio and landscaping choices, and add-ons like heaters, covers, lighting, and fencing. That matters because the best financing options for a $60,000 project may not be the best options for an $85,000 or $120,000 backyard project.

Pool Loan Options and Personal Loans

When people ask how to finance a pool, pool loans usually come up first. In practice, these often work like unsecured personal loans. That can make them useful for buyers who want speed or who do not want to borrow against their home. The tradeoff is cost. Unsecured loans often carry higher rates and lower borrowing limits than equity-based options.

This route can make sense when you want a simple approval process, you have strong credit, or you need funding that works well alongside other sources. It can also help if you want to move quickly on the construction timing. Specialty pool lenders may offer larger unsecured loan amounts and longer terms, but your rate and approval still depend on credit, income, and overall financial profile.

Swimming Pool Financing Options: Home Equity Loan vs. HELOC

For many homeowners, the best way to finance a pool comes down to home equity. A home equity loan gives you a fixed amount borrowed against your home’s equity. That structure works well when you know your project budget and want predictable payments.

A home equity line of credit (HELOC) works differently. It gives you a line of credit that you can draw from as needed, with flexibility that can help when your project includes staged expenses like decking, landscaping, fencing, or later upgrades.

The tradeoff with both options is simple. Rates often look better than unsecured loans, but your home secures the debt. You also need enough equity to qualify, and you may face appraisal, closing, or lender fees depending on the product.

Ways to Finance a Pool With Cash-Out Refinancing or Dealer Financing

A cash-out refinance replaces your current mortgage with a larger one and gives you the difference in cash. This option can help homeowners tap equity for improvements, but it can also extend repayment and increase risk if payments become too heavy. It usually makes the most sense when rates are favorable, and you have meaningful equity built up.

Some homeowners also explore pool dealer financing programs, which usually means your builder or dealer conveniently connects you with a financing partner. Be sure to compare dealer options against outside lenders so you understand the rates, terms, fees, and monthly payments clearly.

Is Paying Cash the Best Way to Finance a Pool?

Not every conversation about swimming pool financing options should end with a loan. Paying with cash out of pocket for at least a portion of the price tag can lower interest rates, reduce total project cost, and give you more flexibility later. It also pairs well with a hybrid strategy, such as using savings for the pool shell and financing only the patio or upgrades.

What’s the Best Way to Finance a Pool?

The honest answer is that the best way to finance a pool depends on three things:

  1. Your credit profile
    2. Your available home equity
    3. The size of the backyard project you want to build

If a low rate matters most, home equity products usually deserve a close look. If speed and simplicity matter most, pool loans or personal loans may fit better. If you want the lowest total cost, paying cash often wins out. Many homeowners land somewhere in the middle and use a combination.

Compare Pool Financing Options Before You Commit

A smart next step is to run the numbers before you talk yourself into or out of any backyard pool project. Try out the Thursday Pools Financing Calculator to estimate potential daily or weekly payments based on loan amount, interest rate, and term. Then connect with a local independent dealer to talk through your pool vision, your site, and the financing possibilities that fit your budget.

 

FAQ: Pool Financing Options

What are the most common pool financing options?

The most common pool financing options are pool loans from specialty lenders, home equity loans, HELOCs, cash-out refinancing, personal loans, and paying cash. Many buyers use a combination instead of relying on one source.

What is the best way to finance a swimming pool?

Best for lower rates usually means a home equity loan or HELOC. Best for speed and simplicity often means a pool loan or personal loan. Best for lowest overall cost means paying cash. The right answer depends on your credit score, home equity, and total project budget.

What credit score is needed to finance a pool?

Requirements vary by lender, but higher scores usually unlock better rates and terms. Some lenders may consider borrowers in the mid-600s, while stronger credit generally improves approval odds and pricing.

How much can you finance for a swimming pool?

Loan amounts vary widely by lender and borrower profile. Some specialty lenders advertise loans from $20,000 up to $200,000 or more, while your actual approval depends on credit, income, and overall financial picture. Many fiberglass pool projects fall somewhere within the $50,000 to $120,000 range.

Is it better to finance a pool or pay cash?

Paying cash avoids interest and lowers the total project cost. Financing preserves savings, spreads cost over time, and can make a larger backyard plan possible sooner. Many homeowners choose a mix of cash plus financing.

How long are pool financing terms?

Terms vary by product, but 7- to 20-year repayment windows are common. Longer terms usually have lower monthly payments, while shorter terms reduce total interest paid.

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. 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 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

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.
