Forty floor drains. That's what my plumber counted when we finished the rough-in on a 3,200-square-foot laundromat last fall — forty drains, twelve trench sections, and a 4-inch main we had to core through 14 inches of existing slab to reach. The plumbing bill alone came to $87,000, which was more than the entire HVAC and electrical packages combined on the retail tenant space next door.
That's the thing nobody tells you about laundromat buildout cost: it's a plumbing job wearing a retail costume. The Coin Laundry Association pegs total startup cost for a new store at $200,000 to $500,000, and stores in high-cost metros routinely blow past $700,000. But the split inside that number is what matters if you're a contractor bidding the work or an owner trying to figure out why three GCs gave you three wildly different quotes.
I've built four of these now — two ground-up conversions of former retail space, two remodels of dead laundromats — and my shop's margins on laundromat work have beaten our typical commercial remodel margins by 4 to 6 points every time. Here's why, and here's where every dollar goes.
The Real Split: Machines vs. Construction
The first mistake every new laundromat owner makes is thinking the machines are the whole budget. They're roughly half — and on smaller stores, less than half.
What the equipment actually costs
A commercial washer runs $3,500 to $12,000 depending on capacity. A 20-pound front-loader from Speed Queen or Dexter sits around $3,800 to $5,500; a 60-pound machine runs $9,000 to $12,000; the 80-pound monsters that do comforters and commercial accounts push $14,000. Dryers are cheaper per unit — a 30-pound stack dryer runs $5,000 to $7,000 — but you need roughly one dryer pocket for every washer.
A typical 2,500-square-foot store carries 25 to 35 washers and 25 to 30 dryer pockets. Run the math and you land at $180,000 to $280,000 in equipment for a mid-size store. Distributors like Alliance Laundry Systems will finance 70 to 90 percent of that at 8 to 11 percent over 7 to 10 years in 2026's rate environment, which is why owners fixate on the machine number — it's the financeable half.
What the construction actually costs
The buildout — the part my shop bids — runs $65 to $150 per square foot for laundromat-specific work in 2026, per RSMeans-adjusted figures and my own job costing. On a 2,500-square-foot store, that's $160,000 to $375,000 of construction before a single machine rolls through the door. Compare that against general vanilla-shell retail buildout at $45 to $80 per square foot and you see the premium: laundromats cost 50 to 90 percent more per foot to build than the nail salon two doors down.
The premium comes from exactly three trades, and I'll take them in order of pain.
Where the Money Goes: The Three Expensive Trades
Plumbing: the budget killer
Plumbing is 25 to 35 percent of a laundromat buildout — the single biggest construction line item. On my last job it was 31 percent of the construction contract.
Every washer needs hot supply, cold supply, and drainage, and commercial washers dump water fast — a 60-pound machine discharges 25 to 40 gallons in under two minutes. Multiply by 30 machines that can all hit their drain cycle inside the same five-minute window and you're sizing for a flood, not a trickle. That means trench drains under the washer rows, a 4-inch or 6-inch building drain, and in most jurisdictions a lint interceptor — a $4,000 to $9,000 installed box that the health and sewer authorities will absolutely make you put in.
Then there's hot water. A 30-washer store needs 250 to 400 gallons of hot water capacity with fast recovery. That's two or three high-efficiency commercial water heaters at $8,000 to $15,000 installed each, or a boiler-and-storage setup running $25,000 to $45,000. Cutting corners here is how you end up with the 2 p.m. Saturday cold-water complaints that kill a store's Google rating.
Budget reality: $60,000 to $110,000 in plumbing on a mid-size store, and that assumes your slab cutting goes clean. Hit post-tension cables or discover the existing 3-inch sewer lateral can't be upsized without trenching the parking lot, and add $15,000 to $40,000. I now put a $10,000 slab-and-lateral contingency in every laundromat bid and I've used it three times out of four.
Electrical: the 400-600 amp surprise
Almost no second-generation retail space has the service a laundromat needs. Your typical strip-center bay comes with 200-amp single-phase service. A 30-machine laundromat with electric dryers needs 600 to 800 amps; even with gas dryers you're at 400 amps minimum once you count washer motors, lighting, HVAC, and water heating.
A service upgrade from 200A to 600A runs $25,000 to $60,000 in 2026, and that's if the utility transformer can handle it. If the utility has to upsize the transformer or bring three-phase to the building, you're waiting 4 to 9 months and the utility contribution charges can add another $10,000 to $30,000. I tell every laundromat client the same thing: get the utility load letter before you sign the lease, not after. One client ignored that advice and paid rent on a dead space for seven months waiting on a transformer.
Total electrical package on a mid-size store: $45,000 to $85,000. Before you bid or buy, run the actual connected load through our free electrical load calculator — it takes ten minutes and it's saved my estimators from underbidding service gear twice this year.
Gas and venting: the quiet third trade
Gas dryers dominate the industry — roughly 85 percent of new stores spec gas, per Coin Laundry Association surveys — because gas costs about half as much per dry cycle as electric resistance. But 30 dryer pockets pull 2 to 3 million BTU/hour, which usually means a new gas service, a 2-inch or larger meter set, and $12,000 to $25,000 in black iron distribution.
Dryer venting is its own line: each dryer needs a dedicated or manifolded exhaust run, and code caps equivalent duct length hard. Long vent runs mean booster fans and makeup air. Makeup air is the one everybody forgets — 30 dryers exhausting 200+ CFM each will depressurize the building and backdraft your water heaters unless you're bringing in 6,000+ CFM of tempered makeup air. That's a $15,000 to $35,000 HVAC line that shows up in exactly zero owner pro formas I've ever been handed.
Laundromat Buildout Cost Breakdown Table
Here's the full stack for a typical 2,500-square-foot, 30-washer store in a second-generation retail space, based on my 2025-2026 job costs and industry figures:
| Line Item | Low | High | % of Construction |
|---|---|---|---|
| Plumbing, drains, water heating | $60,000 | $110,000 | 28-32% |
| Electrical + service upgrade | $45,000 | $85,000 | 20-24% |
| Gas piping, venting, makeup air | $27,000 | $60,000 | 13-16% |
| HVAC (cooling a humid box) | $18,000 | $35,000 | 8-10% |
| Flooring (sealed/epoxy or tile) | $15,000 | $30,000 | 6-8% |
| Demo, framing, drywall, paint | $20,000 | $40,000 | 9-11% |
| Storefront, doors, ADA restroom | $12,000 | $28,000 | 6-8% |
| Permits, design, engineering | $10,000 | $25,000 | 5-7% |
| Construction subtotal | $207,000 | $413,000 | 100% |
| Equipment (washers/dryers) | $180,000 | $280,000 | — |
| Payment systems, carts, signage | $20,000 | $45,000 | — |
| All-in project total | $407,000 | $738,000 | — |
Notice the all-in number lands above the Coin Laundry Association's $200K-$500K published range at the high end. That's not me padding — it's 2026 costs in metro markets doing what they've done since 2021. BLS producer price data has plumbing fixture and fitting costs up roughly 28 percent since 2021, and copper's 2026 run hasn't helped. If someone quotes you a full 30-machine store buildout for $150,000, one of you is about to have a very bad year.
Franchise vs. Independent: What It Does to the Budget
About 30 percent of new stores now open under a franchise or branded-distributor program, and the construction delta is real.
The franchise premium
Franchise programs — think branded concepts with required trade dress — add $40,000 to $100,000 to a buildout. You're paying for specified finishes (their tile, their millwork package, their lighting spec), a required signage package that runs $15,000 to $35,000 versus $8,000 for an independent's channel letters, and design review cycles that add 4 to 8 weeks to the schedule. Franchise fees themselves run $30,000 to $50,000 upfront plus 5 to 6 percent royalties, but that's the owner's problem, not the construction budget's.
What you get for the premium: a proven layout (machine mix and adjacency plans that took someone else ten stores to figure out), negotiated equipment pricing that can claw back $15,000 to $30,000, and lender comfort — SBA lenders approve franchise laundromat loans at measurably higher rates because the SBA has default history on the brand. SBA 7(a) loans fund the majority of laundromat startups, typically at 10 to 15 percent down.
The independent path
Independents keep the $40K-$100K premium and the royalties, but they eat the design risk. The two saddest laundromats I've ever remodeled were independent stores where the original owner put the folding tables where the dryers should have been and lost 20 percent of their pocket count to a bad column line. If you go independent, pay a laundry distributor's design team (usually free with equipment purchase) or a consultant $5,000 to $10,000 to lay out the store. It's the cheapest insurance in this business.
My contrarian take: the buildout math favors independents, but only for owners who already know retail operations. First-timer with no operations background? The franchise premium is usually cheaper than the mistakes.
Why I Like This Work (and Where the Margins Hide)
Laundromat jobs bid at 15 to 20 percent gross margin in my market against 10 to 12 percent for generic retail TI, because half the GCs who look at the plans get scared off by the drain count and the service upgrade coordination. Fewer bidders, better margins — same reason car wash construction pencils so well for the contractors who've learned the equipment-integration dance. It's the same story I see in restaurant build-outs: specialty MEP density scares off commodity bidders and pays the ones who show up.
The revenue side explains why owners keep building despite the cost. A well-located store grosses $200,000 to $400,000 a year at 20 to 35 percent net margins, mostly in quarters and app payments, with 1.5 to 2 employees. Census Bureau data counts roughly 17,500 laundromats nationwide, and the industry's roughly $5.4 billion in annual revenue has grown straight through every recession since the 1990s — renters need clean clothes in good years and bad. That recession resistance is exactly why SBA lenders like the category.
If you're pricing one of these — as the builder or the buyer — start by running your square footage and machine count through our free construction cost estimator to frame the construction half, then get real distributor quotes on the equipment half. The pro formas floating around laundromat Facebook groups are three years stale.
Frequently Asked Questions
How much does it cost to build a laundromat from scratch in 2026?
Plan on $407,000 to $738,000 all-in for a typical 2,500-square-foot, 30-washer store in second-generation retail space — roughly $207,000 to $413,000 in construction plus $180,000 to $280,000 in equipment and $20,000 to $45,000 in payment systems, carts, and signage. Small-town stores with existing adequate utilities can land near $250,000 total; big-metro stores with full service upgrades regularly clear $700,000.
What's the most expensive part of a laundromat buildout?
Plumbing, at 28 to 32 percent of construction cost — $60,000 to $110,000 on a mid-size store. Forty-plus drain connections, trench drains, a lint interceptor, upsized sewer laterals, and 250 to 400 gallons of hot water capacity make it the densest plumbing job in retail construction. Electrical service upgrades to 400-600 amps run a close second at $45,000 to $85,000.
Can I put a laundromat in any retail space?
No — and this is the pre-lease diligence that saves fortunes. You need a sewer lateral that can handle simultaneous discharge (4-inch minimum, 6-inch preferred), electrical service upgradeable to 400+ amps, gas availability at 2-3 million BTU/hour, and a landlord who'll allow slab cutting. A space that fails on sewer or transformer capacity can add $50,000 to $100,000 and 6+ months. Get utility load letters and a sewer camera inspection before signing anything.
Is a laundromat franchise worth the extra buildout cost?
The franchise premium runs $40,000 to $100,000 in construction plus $30,000 to $50,000 in fees and 5 to 6 percent royalties. In exchange you get proven store layouts, equipment discounts worth $15,000 to $30,000, and easier SBA financing. For experienced operators, independent usually pencils better; for first-time owners, the franchise premium tends to cost less than first-store layout and equipment-mix mistakes.
How long does a laundromat buildout take?
Four to seven months of construction after permits, but the critical path is almost always the utility service upgrade — transformer and three-phase work can take 4 to 9 months from application in 2026, so file with the utility the week you sign the lease. Permits add 6 to 12 weeks depending on jurisdiction. Equipment lead times from major manufacturers are running 8 to 14 weeks, so order machines before drywall.
What margins should a contractor expect on laundromat work?
In my market, 15 to 20 percent gross versus 10 to 12 percent on commodity retail TI. The MEP density thins the bid list — many GCs pass on jobs with 40 drains and a 600-amp service coordination. Price the slab-cutting and sewer-lateral risk explicitly (I carry a $10,000 contingency) and hold your number; the owners who shop hardest on price are the ones whose pro formas can't survive contact with a real plumbing bid.
Your Action Item for This Week
If you're a contractor: call your two best plumbing subs and ask if they've done trench-drain and lint-interceptor work, then get on your local laundry distributor's GC referral list — Alliance, Dexter, and regional distributors all keep one, and it's a free lead pipeline almost nobody works. If you're an owner-to-be: before you tour a single space, write down three numbers for every candidate — sewer lateral size, existing amp service, and gas meter capacity — and reject any space that fails two of three. Then run your target square footage through the cost estimator and compare it against whatever pro forma the seller or distributor handed you. The gap between those two numbers is your real negotiation.
