True-Cost Guide · Updated 2026
The kit is roughly half your project. On a typical 11′×16′ build, plan for $975 to $2,450 beyond the kit price: locally sourced boulders and gravel at $500 to $1,200, plants and starter fish at $200 to $500, a GFCI circuit at $0 to $600 depending on how close your power already is, and $75 to $150 of consumables and rentals nobody budgets. Rock is the big one, and it follows a formula: roughly 1 ton of stone per 25 to 30 square feet of pond footprint, split about two-thirds boulders to one-third gravel. Delivery is the line that varies by seller: our bundles include freight; standalone kits ship at flat curbside rates. Every number here is itemized below so your budget matches your project before the first shovel, not after the second rock delivery.
Quick Answer: Beyond-the-Kit Budget, 11′×16′ Pond
No kit includes rock, and rock is the line first-timers underbuy. The working rule of thumb: total stone in tons ≈ pond footprint in square feet ÷ 25 to 30, split roughly two-thirds boulders (6″ to 18″ mixed sizes) and one-third gravel for shelf and bottom cover.
| Pond footprint | Sq ft | Total stone | Split (boulders / gravel) | Typical local cost VERIFY |
|---|---|---|---|---|
| 8′×11′ | 88 | 3 to 4 tons | 2 to 3 / 1 | $300 to $700 |
| 11′×16′ | 176 | 6 to 7 tons | 4 to 5 / 2 | $500 to $1,200 |
| 21′×26′ | 546 | 12 to 15 tons | 9 to 11 / 3 to 4 | $1,000 to $2,200 |
Honest limit of the formula: it fits small and medium ponds. The large build uses fewer tons per square foot because machine-set boulders run larger, so its row comes from real builds rather than the formula. Two buying rules that never change: buy locally by the ton from a landscape supply yard (shipping rock is never worth it), and order the top of your range, because leftover boulders always find a home in the landscape while a second delivery fee never does.
A medium pond looks planted with 15 to 25 plants: marginals at $8 to $15 each around the shelves, two or three lilies at $25 to $40, and a few bunches of oxygenators. Starter goldfish add $30 to $80; remember the pond needs 2 to 4 weeks to cycle before any fish go in, so the fish line is never a day-one cost.
The cheapest plant budget is time: aquatic perennials divide and spread aggressively. A half-planted pond in June is a full pond by August, and a fellow pond keeper's spring divisions are free. If the budget is tight, cut this line, never the rock line.
The pump needs a GFCI-protected exterior outlet, and code does not accept an extension cord from the garage. Three scenarios cover nearly everyone:
| Your situation | Cost | Notes |
|---|---|---|
| Exterior GFCI outlet within 20 feet of the pond | $0 | The pump cord reaches; you are done |
| Power nearby, no GFCI outlet | $150 to $300 | Electrician adds a GFCI outlet to an existing circuit |
| No power near the site | $400 to $600+ | New circuit and trench; long runs and finished landscaping push the top of the range |
Check this before you pick the pond's location, not after: an outlet 15 feet from a beautiful spot beats a $600 trench to a slightly prettier one. Our site disqualifiers guide covers the full location checklist.
Pond kits ship as motor freight on a pallet, not parcel. Two things to know before delivery day: curbside means curbside (the driver brings it to the end of your driveway; moving 300-plus pounds of boxes to the backyard is your job, so have a hand truck or a helper), and freight damage claims have short windows, so open every box the day it arrives, even if the build is weeks away.
What it costs here: our bundles include freight in the listed price. Standalone kits ship at flat curbside rates: $149 small, $199 medium, $249 large. Rock never ships; buy it locally, always.

Calculate My True Cost →Consumables and rentals, $75 to $150: underlayment seam tape, waterfall foam if your kit excludes it, extra tubing for a long skimmer-to-falls run, and a sod cutter rental. Order the consumables with the kit and save a second shipment.
Spoil handling, $0 to $500: a medium dig produces 8 to 10 cubic yards of soil. Berm it into the waterfall and it is free landscaping; haul it away and it is $300 to $500.
Water, $10 to $30: filling 2,000 gallons from municipal water is cheaper than lunch. The real water cost is the first-fill treatments: $50 to $100 of starter bacteria and chlorine detoxifier if your kit or bundle does not include them.
Year one running costs, $300 to $600: pump electricity, seasonal treatments, and a fall net. Not a build cost, but the number your budget should already know about. Full breakdown in the kit vs. pro cost guide.
1. The rock line. Thin rock coverage exposes liner to sunlight, looks unfinished forever, and is the single most visible corner cut in this hobby. Shrink the pond before you shrink its rock.
2. The underlayment and seam tape. Seventy-five dollars protecting the component you can never access again. Our first-timer mistakes guide prices what skipping it costs.
3. The electrical, by improvising. An extension cord is not a budget strategy; it is a code violation next to water. If the electrician's visit breaks the budget, the honest fix is a closer site or a later build.
4. The kit itself, by downsizing the wet system. Underbuying the pump or filtration to fund rock solves the wrong problem. Cut the plants and the lighting instead; they phase, and here is exactly what phases and what never does.
Plan roughly 1 ton of stone per 25 to 30 square feet of pond footprint, split about two-thirds boulders and one-third gravel. An 11′×16′ pond needs 6 to 7 tons; an 8′×11′ needs 3 to 4. Buy locally by the ton and order the top of the range, because a second delivery fee costs more than leftover boulders.
No kit from any manufacturer includes rock, and none should: shipping stone by freight costs more than the stone. Budget rock as its own line, sourced from a local landscape supply yard, and treat any kit price as roughly half the finished project's cost.
Zero if an exterior GFCI outlet already sits within 20 feet of the pond. Adding a GFCI outlet to a nearby circuit typically runs $150 to $300, and a new circuit with trenching runs $400 to $600 or more. Check outlet distance before choosing the pond's location; it is the cheapest siting decision you can make.
The freight carrier delivers the palletized kit to the end of your driveway, and moving it from there is your job, so plan a hand truck or a helper for 300-plus pounds of boxes. Open every box the day it arrives: freight damage claims have short windows, and discovering a cracked skimmer on dig day is too late.
For a DIY 11′×16′ build: the $4,279 bundle plus $975 to $2,450 of rock, plants, electrical, and consumables lands most projects between $5,300 and $6,800 all-in. Professional installation of the same pond runs $12,000 to $16,000; the full comparison is in our kit vs. pro cost guide.
