Renovation comparisons, decided by your pool's condition

Six comparisons cover the decisions that change a renovation proposal most: finish grade, scope size, deck strategy, heater fuel, sanitizer and how much tile to replace. Each lines the options up on cost, lifespan, maintenance, appearance, climate fit, time out of service, resale and who each suits, then says under which conditions each wins. None declares a universal winner.

See the comparisons

Every renovation choice trades money now against money later and weeks of an empty pool against years of service. Shasta's 2026 lifespan table, 5–10 vs 20+ years, is the clearest example: pebble costs more per job and less per year. SKIN Microplaster's finding that a deck overlay saves 40–60% over replacement is another, with the condition that the slab has to be sound.

The comparisons below use the same sources as the service pages. Read the verdicts, run the calculator with each finish, and take the quiz to see which decision is still open.

The 6 decisions that move the price most

Standard plaster vs Pebble aggregate

Plaster is the classic smooth white or colored interior at Shasta's $3,500 to $6,500 with a 5 to 10 year life. Pebble is an exposed-aggregate finish at $6,000 to $15,000 with a 20-plus year life that hides mottling and staining. Pebble costs more per job and usually less per year; plaster is smoother and cheaper if the horizon is short.

Upfront cost: $3,500 to $6,500 per pool (Shasta 2026); ~$5,500 per 1,000 sq ft (HomeAdvisor 2026); $6,000 to $15,000 per pool (Shasta 2026); ~$6,500 per 1,000 sq ft aggregate (HomeAdvisor)
Lifespan: 5 to 10 years (Shasta 2026); 20+ years (Shasta 2026)
Maintenance: Shows etching, stains and mottling; needs tight chemistry; acid washes shorten life; Hides mottling and stains; tolerates chemistry swings better; scale still forms

Replaster only vs Coordinated remodel

A replaster addresses one problem, the interior, in one short drain cycle. A remodel bundles finish, tile, coping, deck and equipment into one sequence. Bob Vila's averages are close because many remodels are small, but a multi-scope remodel runs $30,000 and up. The question is how many things are wrong and whether the pool must be drained for more than one of them.

Upfront cost: $3,500 to $6,500 plaster; up to $15,000 pebble (Shasta 2026); $5,597 to $15,775 typical, avg $10,483 (Bob Vila 2026); $30,000 to $50,000 multi-scope
What it fixes: Interior finish only; Finish, tile, coping, deck, equipment, features, safety items
Drain cycles: One now; another when tile or equipment need the pool dry; One for everything

Resurface the deck (overlay) vs Replace the deck

An overlay coats a sound slab at $3 to $15 per square foot and saves 40 to 60% over replacement, per SKIN Microplaster's 2026 guide. Replacement demolishes and re-pours at Shasta's $5,400 to $13,500 for 900 square feet, fixes slope, drainage and the expansion joint, and allows new plumbing underneath. The slab's condition decides it.

Upfront cost: $3 to $6 overlay; $6 to $12 cool deck; $8 to $15 stamped, per sq ft (SKIN 2026); most jobs $3,000 to $12,000; $2 to $6 demolition plus $5 to $15 concrete, $15 to $30 stamped, $20 to $40 stone, per sq ft (Shasta 2026)
Lifespan: 10 to 15 years overlay; 15 to 25 stamped (SKIN 2026); Decades for the slab; surface wear over time
What it fixes: Surface wear, minor cracks, color, heat; Heave, slope toward house, cracked beam, drainage, plumbing runs

Pool pump, cartridge filter and grey heater joined by white PVC pipe on a concrete pad by a fence

Electric heat pump vs Natural gas heater

A heat pump pulls heat from the air, costs more to buy and far less to run when the air is warm, and heats slowly. A gas heater costs less to buy, heats fast in any weather and costs several times more per season to run. HomeAdvisor's 2026 average install is $3,094; Fixr's operating range is $200 to $1,800 a year for a heat pump against $800 to $6,000 for gas.

Upfront cost: $2,500 to $7,500 installed (HomeAdvisor 2026); 50-amp circuit; $1,500 to $6,000 installed (HomeAdvisor 2026); gas line sized for 200,000 to 400,000 BTU
Lifespan: Typically 10 to 15 years; 7 to 12 years (HomeAdvisor 2026)
Operating cost: $200 to $1,800 a year (Fixr 2025); $800 to $6,000 natural gas; propane to $12,000 (Fixr 2025)

Convert to saltwater vs Stay on chlorine

A conversion adds a salt cell at HomeAdvisor's $500 to $2,500 and cuts annual chemical purchases to Fixr's $100 to $400 in salt against $300 to $800 in chlorine, with a cell replaced every 5 to 7 years at $200 to $700. Staying on chlorine costs nothing up front and suits short seasons, older heaters and soft-stone decks.

Upfront cost: $500 to $2,500 conversion (HomeAdvisor 2026); generator $1,500 to $2,500 (Fixr 2025); $0; feeder or floater $100 to $500 if replaced
Lifespan: Cell 5 to 7 years, $200 to $700 (Fixr / Bob Vila); Feeder lasts years
Annual consumables: $100 to $400 salt (Fixr); about $50 electricity (HomeAdvisor); $300 to $800 chlorine (Fixr) plus stabilizer

Waterline retile only vs Full interior retile

Waterline retiling replaces the 6-inch band at the bond beam for Shasta's $25 to $30 per linear foot with the water lowered, not drained. A full interior retile replaces every surface in tile at We Fix Ugly Pools' $15,000 to $30,000 or more for 500 square feet, is the longest-lasting interior, and requires a full drain and a sound shell.

Upfront cost: $1,500 to $2,500 for a 10 x 20 pool (Shasta 2026); $1,200 to $6,000 for 60 to 100 ft (We Fix Ugly Pools 2026); $15,000 to $30,000+ for 500 sq ft (We Fix Ugly Pools 2026); $3,000 to $20,000 range (HomeAdvisor 2026)
Lifespan: 15+ years on a sound beam with a working joint; Longest of any interior (HomeAdvisor); grout is the maintenance item
Maintenance: Brush the waterline weekly; descale periodically; Grout cleaning and sealing; scale on horizontal surfaces

Full comparison, verdict and FAQs →

Why do these six decisions matter more than the color?

Because each changes the schedule, the drain count or the operating bill, and each is hard to undo. A finish grade sets the next resurfacing date a decade out. A scope decision sets how many times the pool is drained. A deck strategy sets whether the expansion joint gets fixed. A heater fuel sets the largest annual bill after the pump, with Fixr showing $200–$1,800 vs $800–$6,000 per year. A color is a showroom choice.

HomeAdvisor's annual upkeep figure of $960–$1,800 per year is the baseline every pool pays; the equipment and sanitizer choices here move it by hundreds a year, and the finish choice moves the once-a-decade bill by thousands.

How should you read the tables?

Each row is a factor, each cell a sourced range or a plain statement, and where the source sells what it describes, the text says so: Shasta builds and renovates pools, SKIN Microplaster sells overlays, Pentair makes pumps. The 'best for' row is the summary. The verdict paragraphs describe the conditions that flip the decision, which your pool's age, climate and problem list determine.

Bring your constraints: the symptom, the bucket test, the pool's age, your region from the regional notes, and how long you plan to keep the house. With those, a comparison is a decision.

What about ownership cost over the next finish cycle?

Think in cycles rather than jobs. River Pools puts concrete resurfacing at every 10–15 years, and the choices here decide whether the next cycle is eight years or twenty. A pebble finish, a fixed expansion joint, a variable-speed pump, a heat pump in a warm climate and a salt cell on a long season each push the pool's running cost down over that cycle; a standard plaster, an ignored joint and a single-speed pump push it up.

Opendoor's estimate of routine pool upkeep at $3,000 to $5,000 a year and major repairs at $5,000 to $15,000 per event is the frame for the whole set. The remodel page shows where each decision sits in a full proposal.

How do you check a real proposal against these tables?

Line the proposal up row by row. Shasta prices waterline tile at $25–$30 per linear foot and Bob Vila prices coping at $30–$50 per linear foot, so a proposal that does both on a 90-foot perimeter for $9,000 sits inside the range, and one at $18,000 needs a reason: glass tile, a curved beam, a new expansion joint or demolition of coping that was bonded rather than set. The tables hand you the question, not the verdict. The same applies to the drain line, where HomeAdvisor lists $45–$65 per hour; a $900 drain charge on a small pool is worth asking about.

Then look for what the proposal leaves out. Every pair below has a row the cheaper option tends to skip: the leak detection before a replaster, the joint reset under a deck overlay, the electrical run for a heat pump, the cell replacement schedule for a salt system. If a factor row in the table has no matching line in the proposal, ask whether it was excluded or assumed. A written scope that answers all eight rows for the pair you chose is one you can set beside the next bid; use the estimate request to get two or three built the same way.

Comparison questions

Which comparison should I read first?

Plaster versus pebble if the interior is the problem, since it sets the largest single number. Replaster versus remodel if you are unsure how much is wrong. Heat pump versus gas if the heater is failing. The deck and tile comparisons follow from the interior decision.

Do the comparisons account for my climate?

Each has a climate-fit row and the verdicts cite EIA's 2024 regional data where it applies, such as year-round use in the South. The locations page covers the calendar and the regional hazards in more depth.

Why are trade sources like Shasta and SKIN cited?

They publish component-level pricing and lifespans that neutral guides do not. Each is identified as a seller of what it describes, and the tables pair them with HomeAdvisor, Bob Vila, Fixr and CostHelper wherever a neutral figure exists.

Can I compare three finishes?

Read plaster versus pebble and treat quartz as the middle: Shasta's $7,000 to $10,000 and 10 to 15 years. The calculator prices all three on your square footage.

How current are the figures?

Mostly 2025 and 2026 guides, EIA's 2024 survey data released in 2026, and CPSC's 2026 report. Each figure carries its year and updates when the source does.

What if my contractor disagrees with a verdict?

Ask what in your pool changes it. A contractor who says pebble is wrong for your steps may be right about the texture; one who says an overlay will hold on a heaved slab should be asked how. The comparisons are national; the contractor is looking at your pool.

Is there a comparison for pumps?

Not as a pair, because the 2021 federal rule makes variable speed the default for most residential pumps sold new. The equipment page covers sizing, savings by pool size and what the swap needs.
