How much more does an inground pool cost than an above-ground one?

Roughly ten times at the point of purchase in Ontario. Toronto Pool puts an above-ground pool at $1,000 to $6,000 and Easy Pools at $3,000 to $15,000 installed, against $40,000 to $120,000 for an inground vinyl liner pool depending which builder you ask. Over fifteen years the multiple narrows, because the inground pool spreads its cost over more seasons and both pools buy liners, but it never gets close to even.

What is a semi-inground pool and is it worth it?

A pool set partly into the ground with the rest of the wall left visible in aluminium, resin or polymer. Easy Pools prices them at $20,000 to $50,000 installed and Swimpool 360 at $20,000 to $45,000, so they sit squarely between the other two. They earn their money on a sloped lot, where a fully inground pool would need expensive retaining and grading, and Swimpool 360 argues they are genuinely underused in the GTA for exactly that reason.

How long does an above-ground pool last?

The liner is the part with a published life, and Swimpool 360 puts it at 8 to 12 years above ground against 10 to 15 years inground, with replacement at $1,500 to $3,000 against $4,500 to $8,500. So an above-ground pool relines more often and pays much less each time. The structure itself outlives that if the pool is closed properly every autumn, which in Ontario matters more than anywhere mild.

Do I still need a fence around an above-ground pool in Toronto?

Almost certainly yes. Chapter 447 of the Toronto Municipal Code applies its enclosure rules to swimming pools generally, and its only above-ground exception is for pools erected before 6 July 2000 that already meet a specific list: at least 1.2 metres above grade, a guard of at least one metre around any deck, a combined height of no more than 2.6 metres, nothing on the outside that helps a climb, and a gated enclosure at the point of access. A pool bought this year gets no exemption from that list.

Does an above-ground pool hurt resale value?

It is not a fixture in the way an inground pool is, which cuts both ways: it does not add the value an inground pool can, and it also does not sit there as a liability a buyer has to accept. Precision Landscaping makes the related point that Ontario homeowners routinely start their search with US figures and get a shock, and the same distortion is behind most of the resale claims in either direction. This page prices the ownership, not the resale, because Ontario sources publish one and not the other.

What does this comparison leave out?

Chemicals, pump electricity and heating, on purpose. All three scale with the water a pool holds, an above-ground pool holds a fraction of what an inground pool does, and no Ontario source publishes those figures separately for the two. Adding an estimate would decide the comparison with a number nobody printed. The pool chemical calculator and the annual maintenance calculator on this site handle both, once you know your own volume.

Above ground or inground: what the gap really is

Last updated:August 28, 2026By The Pool Trade Desk

About ten times the price on day one, and still several times it after fifteen years of liners and openings. Set the years you expect to own the pool and the tool totals all three, on published Ontario figures.

The same swim, three ways to pay for it

How long do you expect to own it? (years)

Long enough matters: the liner is the line that only appears with time.

The gap

Over 15 years an inground vinyl pool costs 5.9 to 5.8 times what an above-ground pool does, or $43,125 to $116,125 more in cash.

Semi-inground sits between them at $32,000 to $70,500, and it is the option most GTA homeowners never consider. On a sloped lot it solves a problem an inground pool solves with a retaining wall.

Get all three priced on your own yard

Three things are counted here because every option has a published Ontario figure for them: the build, the liner when it wears out, and a company opening and closing the pool. Chemicals, pump electricity and heat are NOT counted, and that is deliberate. They scale with the water a pool holds, an above-ground pool holds a fraction of what an inground one does, and no Ontario source publishes those costs per pool type. Estimating them would decide this comparison with a number nobody printed.

What is counted, and what is left out on purpose

Method

Three lines, because all three options have a published Ontario figure for each of them: what it costs to put the pool in, what a liner costs when it wears out, and what a company charges to open and close it every year. The liner is the one that only shows up with time, and it is why a fifteen year comparison reads differently from a showroom conversation. Swimpool 360 publishes both sides: 8 to 12 years and $1,500 to $3,000 above ground, 10 to 15 years and $4,500 to $8,500 inground.

The liner count pairs a long life with the cheap price and a short life with the dear one, so the cheap column is genuinely the cheap case and the dear column is genuinely the dear one. Pairing them the other way round would produce a range wider than anything that can actually happen to a real pool.

Chemicals, pump electricity and heating are deliberately absent. All three scale with how much water a pool holds, an above-ground pool holds a fraction of what an inground pool does, and no Ontario source publishes either figure separately for the two kinds. Putting an estimate in would decide the whole comparison with a number nobody ever printed, so instead the omission is stated. Work out your own volume with the pool volume calculator and the running costs follow from that.

One thing that is the same either way and often assumed not to be: the fence. Chapter 447 of the Toronto Municipal Code applies its enclosure rules to swimming pools generally. Its only above-ground exception covers pools erected before 6 July 2000 that already meet a specific list of conditions, so a pool bought this year is enclosed like any other. That is why the fence is not a line on this page: it does not move the comparison.

Where these figures come from

Provenance

Six Ontario sources and one City of Toronto bylaw. Swimpool 360's July 2026 liner guide is the one that makes this comparison possible at all, because it publishes life and replacement cost separately for above-ground and inground pools.
