Can You Remodel an Inground Pool? A Practical Guide for Homeowners

Yes, you can remodel an inground pool to update its features, materials, shape, or even size. The feasibility depends on your pool’s structural condition, budget, and local building codes—common projects range from $5,000 resurfacing jobs to $50,000+ transformations involving new tile, coping (the pool’s edge material), or expanded dimensions.

This guide examines key aspects of pool remodeling: assessing your pool’s shell integrity, comparing costs of different upgrade tiers, and exploring design trends like modern tile patterns or integrated spas. We’ll break down regional permit requirements (including California’s strict codes) and provide tips for vetting contractors.

Learn when resurfacing with materials like Marcite (a white plaster finish) makes sense versus full retiling. Find out how expanding or reducing pool size affects project timelines and budgets. Get clarity on warranties, drainage needs during renovations, and long-term maintenance impacts.

Assessing the Feasibility Of Remodeling Your Inground Pool

Before breaking ground on your remodeling an inground pool project, a thorough evaluation sets the stage for success. Start by asking: Does the existing structure support your vision, or will it demand compromises? Planning and assessing your needs can help you design the perfect layout. If you are considering building your own inground pool, careful preparation is essential to achieve your dream oasis.

Key Indicators Your Pool Needs Remodeling

Visible cracks in plaster, rusty rebar stains, or tiles that pop off signal structural stress. Persistent leaks losing ¼ inch of water daily often point to failing plumbing or compromised shells. Outdated designs like shallow-only depths or cramped decks may no longer suit your lifestyle. Safety risks, such as non-compliant drain covers from pre-2008 builds, require immediate attention under the Virginia Graeme Baker Pool Act. One way to protect your pool and improve its efficiency is by using a solar pool cover. When properly attached, a solar pool cover can help retain heat and reduce water evaporation.

Structural Limitations Vs. Upgrade Potential

Gunite pools with 6-8 inch thick walls typically handle expansions better than aging vinyl-lined structures. Fiberglass shells resist resizing due to their factory-molded forms. A 2023 National Pool Contractors Association report found 72% of concrete pools built after 1990 can support added features like spillover spas, while pre-1980 builds may need $8,000-$15,000 in shell repairs first. Choosing a pool with lower hardness levels can also enhance longevity. A lower hardness pool minimizes the risk of scale build-up, making maintenance easier and ensuring a more enjoyable swimming experience.

Evaluating Pool Shell Integrity

Contractors use steel probes to check for delamination (hollow spots) in gunite or shotcrete surfaces. Hydrostatic testing verifies if groundwater pressure causes floor heaving. Expect core samples costing $300-$500 per test to measure compressive strength—values below 2,500 psi may require partial rebuilds. Minor cracks under ⅛ inch wide can often be routed and sealed with epoxy injections.

Local Regulations Impacting Modifications

Setback rules in states like Florida require pools stay 10 feet from property lines—expanding might trigger variance requests. California’s Title 24 mandates energy-efficient pumps for all remodeled pools, adding $1,200-$2,500 to budgets. Coastal zones may limit saltwater system installations due to runoff concerns. Always check municipal codes: altering pool depth over 18 inches often needs permit approval.

With feasibility factors mapped, the next step involves aligning your vision with financial realities. Let’s examine cost breakdowns for popular remodeling an inground pool projects.

Cost Factors for Inground Pool Remodeling

Pool remodeling costs swing widely based on project scope. A basic refresh might run $5k-$15k, while full transformations can hit $50k+. Three factors dominate budgets: surface materials, structural changes, and added features. When planning renovations, it’s crucial to consider ongoing costs like energy use. A pool pump electricity cost calculator can help estimate how much you’ll spend on powering your pump after your remodel.

Breaking Down Common Renovation Expenses

Resurfacing eats 40-60% of typical remodels. Tile replacement averages $25-$50 per square foot installed. Plumbing upgrades add $2k-$8k depending on pipe rerouting needs. Energy-efficient pumps cost $800-$2,500 with installation. These factors can affect the total expenses involved in a pool project. It’s important to consider the specific costs associated with pebble tec finishes as well.

Resurfacing vs. Full Renovation Cost Comparison

A standard 14x28ft pool costs $4-$8 per sq.ft. for plaster resurfacing ($3k-$6k total). Full overhauls including decking, tile, and equipment run $15k-$50k. Full demo/rebuilds start at $60k but permit custom shapes. When thinking about a pool’s comfort, the heater size plays a big role. Using a pool heater size calculator can help you choose the right heater for your pool’s specific dimensions and desired temperature.

Marcite Pool Resurfacing: Costs and Benefits

The classic white plaster finish (called Marcite) costs $4.50-$6.50 per sq.ft.. While budget-friendly, it lasts just 7-12 years versus 20+ for pebble finishes. Pros choose Marcite for quick facelifts, blending 90% recycled marble dust with Portland cement.

Budgeting for Size Modifications

Expanding a 400sq.ft. pool by 10% adds $10k-$30k. Costs spike if breaking existing shell walls—steel-reinforced concrete averages $145 per cubic yard. Downsizing requires partial fills ($3k-$8k) but may reduce property value. Maintaining pool water quality is essential to protect your investment. One option is using hydrogen peroxide, which can effectively lower chlorine levels while keeping the water clean and safe for swimming.

Design Possibilities for Pool Remodels

Today’s remodels blend form and function. Over 60% of owners adding features like LED lighting or baja shelves during renovations.

Modern Aesthetic Updates

Glass tile mosaics ($100-$200 per sq.ft.) create shimmering waterlines. Cantilevered concrete coping ($35-$55 per linear foot) gives clean edges. Dark plaster finishes trending, absorbing heat while hiding stains.

Tile Replacement and Coping Styles

6×6 ceramic tiles cost $5-$15 per sq.ft. installed. Natural stone coping runs $20-$45 per foot. Bullnose travertine remains popular for slip resistance. New waterproof grout formulas prevent color fading.

Functional Feature Additions

Built-in spas (15-25k) share pool filtration systems. Tanning ledges (4-6ft wide) cost $4k-$8k with bubblers. Adding a swim jet system? Budget $7k-$12k for professional installation. When considering all these additions, it’s also important to think about the total costs involved. Overall, the installation cost for an above-ground pool can vary greatly depending on size and features.

Integrated Spas and Tanning Ledges

Spillover spas need 18″ elevation above pool waterline. Ledges require 12″-18″ water depth—perfect for loungers. Both features demand extra rebar during construction: #4 steel bars spaced 12″ on center. Maintaining the right pH alkalinity relationship in the water is important for these pools. The pH alkalinity relationship affects how effectively chemicals work to keep the water clean and safe.

With design plans finalized, the next step involves navigating size changes – from permit requirements to excavation methods.

Changing Pool Dimensions: What You Need to Know

Altering your pool’s size opens new options but needs smart plan work. Check soil type, pipe spots, and deck space before moving walls. Most pools can shift shape if shell strength passes checks by pros. Additionally, paying attention to the plumbing is essential. A leak in the pool pump can lead to air getting into the system, which can affect the pool’s performance.

Expanding Your Pool: Methods and Costs

Adding 3-5 feet costs $15k-$30k based on build style. Shotcrete sprays make strong new walls that bond to old shells. Steel walls with vinyl work for fast fixes but last 7-12 years.

Sidewall Extension Techniques

• Cut-and-shoot: Saw old wall, add rebar, spray concrete ($120-$180 per foot)
• Overlay: Bolt new steel forms to edge, fill with cement mix ($90-$140 per foot)
• Vinyl drop-in: Attach track system, hang liner ($60-$100 per foot)

Reducing Pool Size: Practical Considerations

Shrink steps save cash but limit swim space. Fiberglass inserts cut 4-6 feet for $8k-$15k. Fill zones need drain lines sealed and packed dirt tests (85% comp rate). Check local codes – some towns ban size drops over 20%. Keeping your pool’s chemistry balanced is also important. If you’re facing chlorine lock, addressing the issue promptly will help maintain a healthy swimming environment.

Pool Surface Renovation Options

Cracks, stains, or rough spots mean it’s time for new skin. Pick from 3 main types based on cash, look, and how long you want it to last.

Comparing Resurfacing Materials

• White plaster: $4-$6 per sq ft, lasts 7-12 years
• Pebble mix: $10-$15 per sq ft, lasts 15-25 years
• Glass tile: $25-$50 per sq ft, lasts 30+ years

When to Retile Vs. Replaster

Choose new plaster if under 20% tiles chip. Full retile suits pools with mosaic art or salt water damage. Acid wash old plaster first – pH must hit 7.2-7.8 before new layers go on. Tiles need epoxy grout to stop leaks. Just like the care you give to your pool, choosing the right pool stick name is important in games. A good name can reflect a player’s style and skill.

Navigating Permits and Regional Requirements

Rules vary by state – a CA pool job differs from TX plans. Always call your town office first. Most want stamped plans for any wall moves or pipe reroutes.

California-specific Remodeling Regulations

CA Title 24 needs 20% water save steps if you change over 50% of pool parts. Solar covers or VS pumps meet this rule. Fence heights must stay at 60″ post-work.

Permit Process for Structural Changes

• File plans with pool sketches (scale 1:100)
• Soil test reports for size shifts
• Drain plan showing no run-off to streets
• Wait 6-8 weeks for review
• Pay $800-$1,200 fee based on job size

With design plans set, the next step lies in picking the right crew for the work.

Finding Qualified Pool Remodeling Pros

Picking the right team makes or breaks your pool remodel. Look for pros with proof of work on jobs like yours. Ask to see photos of past projects and talk to past clients.

Vetting Contractors for Renovation Projects

Check licenses first. All 50 states need pool pros to hold trade licenses. Ask for proof of general liability coverage ($1M minimum). Search BBB for ratings and read Google reviews. Pros in groups like APSP or NSPF often meet higher standards.

Get 3 bids min. Compare line items. Watch for lowball bids missing key steps like drain work or permit fees. A full remodel bid should cover demo, new parts, debris haul-off, and post-job clean-up.

Understanding Service Scope and Warranties

Contracts must list all tasks. Example: “Remove old plaster, fix 3 shell cracks, install new quartz finish.” Avoid vague terms like “update pool area.” Verify who buys materials – some pros charge 15% markup on supplies.

Warranty Type	Coverage	Avg. Length
Plaster	Cracks, flaking	5 years
Tile	Loose pieces	2 years
Pump	Motor fails	3 years

Note: Structural work like shell fixes may have 10-year warranties. Always get warranty docs in writing – don’t take verbal promises.

With your pro team locked in, let’s tackle common questions home owners ask before breaking ground.
