Free Pool Design Software Compared

Name: comparepoolquotes
Price range: $$$

Genuinely free design software exists, but none of it is pool-specific. Sweet Home 3D costs nothing under the GNU GPL, with no paid tier at all. Planner 5D's free plan costs $0 but caps the catalogue and watermarks renders. Purpose-built pool software is priced for the trade: Pool Studio is $147 a month plus a $95 setup fee.

The short answer

Sweet Home 3D is the only option here that is free forever — GNU GPL, no paid tier, no time limit, no watermark. It is a home-design tool, so a plunge pool is just a shape you draw.
Planner 5D's free plan costs $0 but gives you about half the catalogue and watermarks every render. Useful for testing paving and landscaping ideas around the water.
SketchUp's published plans page lists no free consumer tier — the cheapest is Go at $129 a year, plus a 7-day trial. SketchUp for Schools is free with an education account.
Pool-specific software is trade software: VizTerra $97/month, Pool Studio $147/month, Vip3D $197/month, each with a one-off $95 setup fee and a 30-day free trial.
Every one of these is a drawing tool. None of them price a pool, and a real quote still ranges $25,000–$110,000.

Free forever, freemium, trial, or trade subscription
Tool	What it really costs	Built for pools?	The catch
Sweet Home 3D	Free — GNU GPL v2 or later, no paid tier	No	Interior and home design; you draw the pool yourself as a shape
Planner 5D — free plan	$0	No	About half the furniture catalogue; renders are watermarked
Planner 5D — Premium	From $19.99/month (or $59.99/year)	No	Still a home-design tool with a pool-shaped hole in it
SketchUp Go	$129/year	No	Web and iPad only. No free consumer tier is listed; the trial is 7 days
SketchUp Pro	$399/year	No	Powerful and general-purpose — a long learning curve for one backyard
VizTerra	$97/month + $95 setup	Landscape and hardscape only	Priced per seat, for a business
Pool Studio	$147/month + $95 setup	Yes	30-day free trial, then a trade subscription
Vip3D	$197/month + $95 setup	Yes	The photorealistic tier; overkill for a single project

Currencies and regional pricing — read this before you compare

Three of these vendors are based in the United States and publish prices without a currency qualifier on the page itself. Structure Studios, which makes VizTerra, Pool Studio and Vip3D, lists its tiers as plain dollar amounts; so does Trimble for SketchUp. Planner 5D is messier still — its pricing page can display Australian dollars for some tiers while its own FAQ quotes United States pricing.

We have reproduced the published figures exactly as each vendor states them. Treat them as United States dollars unless your own checkout says otherwise, and budget for the exchange rate plus GST on top. If a figure matters to your decision, take it from the vendor's checkout, not from a comparison table — including ours.

What 'free' actually means in this category

There are four different things being marketed as free, and they are not close to equivalent.

Free forever, no paid tier. Sweet Home 3D is released under the GNU General Public License, version 2 or later. There is no premium version to upsell you to, no time limit, and the licence explicitly allows you to publish what you make for personal or commercial purposes.

Freemium. Planner 5D's free plan really does cost nothing and really does let you build unlimited projects in 2D and 3D. It also holds back roughly half the catalogue, blocks floor-plan upload, and stamps a watermark on renders.

Time-limited trial. Pool Studio gives you 30 days with full features and no credit card. SketchUp offers 7 days. Both are evaluations, not entry tiers.

Free for a specific audience. SketchUp for Schools is free with a Google Workspace or Microsoft education account. That is a real free product — for students.

The genuinely free options, and what they cannot do

The honest summary is that free software will let you lay out a backyard and place a rectangle of water in it. That is genuinely worth doing: it will tell you how much lawn is left, where the paving runs, and whether the shed has to move.

What it will not do is anything pool-shaped. There is no coping library, no waterline tile, no reticulation or pump set-out, no shell catalogue matched to what an Australian manufacturer actually moulds, and no awareness at all of a 1-metre waterline setback or a 900mm non-climbable zone. You are drawing a swimming-pool-coloured box in a house planner.

Pool-specific software is trade software

The purpose-built products in this category are sold to pool builders and landscape designers as a per-seat business subscription, with a one-off setup fee on top of the plan. The pricing reflects that: the entry landscape tier is $97 a month, the pool tier is $147 a month, and the photorealistic tier is $197 a month, each discounted about 15% if you pay annually.

For a homeowner designing exactly one pool, that is roughly the cost of a fence panel per month to learn a professional CAD package. The 30-day trial is real and requires no credit card, so if you are the sort of person who enjoys this, a focused month is a legitimate way to use it. Most people should not.

What most homeowners should do instead

Three things, in this order, and they cost nothing.

Mark it out. A garden hose on the lawn at full size, including the paving and coping, beats any screen. Live with the outline for a week.

Render the look, not the layout. An AI visualiser will show you finishes and shapes against your own back fence in under a minute, free for the first preview. It is a taste tool, not a plan.

Let the builders design. Most pool builders produce a 3D design as part of winning the job, drawn on your measured block by someone who knows what their supplier moulds. Ask at the quote stage whether a design is included, who owns it, and whether it is binding on the contract.

Common questions

Is there any genuinely free pool design software?

Not pool-specific, no. The closest is Sweet Home 3D, which is released under the GNU General Public License version 2 or later, is free to use with no paid tier, and lets you publish your designs for personal or commercial purposes. You draw the pool yourself as a shape.

Is SketchUp still free?

Not for consumers, on the current published plans. Trimble's plans and pricing page lists Go at $129 a year as the entry tier with a 7-day trial, and no perpetual free web tier. SketchUp for Schools remains free with a Google Workspace or Microsoft education account.

How much does Pool Studio cost?

$147 per user per month, or $125 a month billed annually, plus a one-time $95 setup fee, according to Structure Studios' pricing page. There is a 30-day free trial with no credit card required.

Is Planner 5D free plan good enough to design a pool?

It is good enough to lay out the yard around one. The free plan costs $0 and allows unlimited projects, but it restricts you to about half the catalogue and watermarks exported renders.

Will my pool builder give me a 3D design?

Many include one when quoting. Ask three questions before you rely on it: is the design included or charged, does it reflect a measured site, and does the contract build what the picture shows.
