The 72-Hour Water & Coffee Setup: A Checklist for Spaces That Open Monday

Last April a client called me on a Tuesday afternoon. They'd signed the lease on a new office, move-in was Friday, and forty people were starting Monday. Furniture was handled. Catering was handled. Nobody had thought about where the water and the coffee would come from.

I coordinate rushed commercial fit-outs — roughly 60 of them over the past nine years, everything from two-person studios to a 200-seat event space. The water-and-coffee corner is almost always the thing that gets left to the last 48 hours. So here is the checklist I actually run, in the order I run it. Seven working steps, then a handover walkthrough. Copy it, adapt it, don't skip step one.

Who This Checklist Is For

You have a space coming online in under a week — new office, temporary pop-up, a kitchen whose countertops just went in — and you need drinking water, hot drinks, and possibly real cooking capability without anyone getting sick or tripping a breaker. If you have three months and an MEP engineer, you don't need this page. If you have 72 hours, keep reading.

Step 1: Test the Water Before You Buy a Single Filter

This is the step nearly everyone skips, and it's the one that decides whether you spend $60 or $900.

Municipal water in most of the US is safe, but taste and hardness swing wildly from one building to the next — sometimes from one floor to the next in older buildings with mixed pipe materials. Hard water scales up kettles and espresso boilers within months. Heavily chlorinated water tastes like a swimming pool no matter what you brew with it. A $25 hardware-store test kit, or your utility's annual water quality report (utilities are required to publish one), tells you which problem you actually have before you spend anything.

I don't have hard data on how many teams skip this. Anecdotally, out of the fit-outs I've run, maybe four in ten tested first. The other six bought whatever the last office had.

Step 2: Choose the Filtration Route — Jug, Faucet-Mount, or Under-Sink

Three options, three different tradeoffs. Pick based on headcount and whether there's a fridge.

Countertop jug — cheapest entry, no plumbing, no landlord permission. Fine for up to about 10 people. Above that you're refilling it constantly. A Brita-type jug runs $25–45 with cartridges around $8–12 each in multi-packs (retail pricing as of early 2025; verify current rates before ordering).

Faucet-mount — instant filtered water at the sink, no fridge shelf space, but it eats your only sink faucet. The Brita Basic on-tap faucet water filter system sits in this category, and so do most add-on units.

Under-sink or plumbed-in — best for 15+ people, worst for a 72-hour timeline because it usually needs a plumber and landlord sign-off.

I went back and forth between a jug and a faucet-mount unit for most of a week on one project. The jug was cheaper up front and required touching nothing. The faucet mount gave free-flowing water at the sink and freed up the only fridge shelf we had. I went with the faucet mount because the space had no fridge at all, and it worked — but for a six-person team I'd take the jug every time.

The faucet-mount catch that kills projects

Before you order any add-on faucet filter, get under the sink and look at the faucet. If it's a pull-down or pull-out sprayer, the filter almost certainly will not fit, and no adapter will rescue you. If the aerator is concealed or non-standard, you may need a specific adapter — and adapters have lead times measured in days, not hours.

Forty seconds with a flashlight saves you a week.

Step 3: Commission and Clean the Dispenser Properly

This is the part people get wrong even when they buy the right equipment. If you're setting up a jug or dispenser, here's the sequence that actually matters — and it applies whether the unit is brand new or has been sitting in storage since the last office.

1. Soak the new cartridge in cold water for about 15 minutes, then run and discard two to three full fills. The first pass or two will look cloudy or taste flat. That's normal — it's fine carbon dust and trapped air, not a defect.
2. Never rinse a cartridge with hot water. Hot water degrades the carbon block and can push fines through. Cold or room temperature only.
3. Hand-wash the jug body, reservoir, and lid with warm water and mild dish soap. No bleach, no harsh abrasives. Check your model's manual on the dishwasher — many jug bodies are top-rack safe, but the lid seals and cartridge housing usually are not.
4. Scrub the spout and the seams around the lid with an old toothbrush. This is where biofilm builds and where nobody looks.
5. Clean monthly at minimum; every two weeks if the water is hard or the unit sits in sunlight. Sunlight plus standing water is a bad combination.
6. If the unit is going into storage, dry it completely first. A damp seal left in a closet for three months comes back with mold.
7. Change cartridges on the indicator, not the calendar. The two-month rule on the box assumes average water. Hard water areas will burn through a cartridge noticeably faster.

One thing nobody mentions: if a cartridge has already been through a dishwasher cycle, throw it out. It's done.

Step 4: Kettles — the Infuser Is Not the Important Part

If you're buying an electric kettle with tea infuser, resist the urge to optimize the infuser. Mesh baskets are the cheapest component on the unit and the easiest to replace with a $6 basket or a $4 box of paper filters.

The variables that actually matter:

• Variable temperature control. Green tea wants roughly 175°F, black tea near boiling, and if the kettle only does one setting, someone on your team is going to drink bitter green tea and blame the tea.
• What touches the boiling water. Glass and stainless are fine. Cheap plastic lids and plastic interior components are where a faint off-taste comes from after a few months.
• Whether the infuser basket is wide enough for leaves to expand. A narrow cylinder of mesh turns good loose-leaf tea into something closer to a tea bag.

For a shared office, buy two kettles rather than one large one. It's cheaper than the queue argument.

Step 5: If There's a Kitchen, Check the Circuit Before the Stove

A 6 burner electric stove with griddle is not a plug-in appliance. It's an electrical project.

These units typically draw somewhere in the 40–50 amp range on a 240V dedicated circuit, and the exact figure varies by model — read the nameplate, don't guess. Three things to confirm before delivery:

1. A dedicated 240V circuit exists and is the right amperage. If somebody proposes sharing it with a water heater or an HVAC unit, that's a hard no. Shared circuits plus a griddle preheating is how you get nuisance trips at exactly the wrong moment.
2. Ventilation is adequate for the space. A griddle produces far more grease-laden vapor than a regular cooktop. Commercial spaces usually have local code requirements here; check with your building department rather than assuming.
3. The floor and doorways can take it. Freestanding 6-burner ranges are heavy, and they don't fit through a standard 30-inch door frame in the crate.

Schedule the delivery for a day when an electrician is on site. Not the day after.

Step 6: The Espresso Machine Question

Somebody always asks what espresso machine does Starbucks use, usually half-joking, sometimes not.

The answer is the Mastrena, built by Thermoplan in Switzerland. It's a super-automatic unit — bean to cup with almost no operator skill required, which is exactly why a chain with hundreds of thousands of baristas uses it. Publicly reported figures put each unit in the five-figure range, and that's before the dedicated water treatment, the electrical work, and the service contract that keeps a commercial machine alive.

Don't buy one. You can't buy one, realistically — the sales channel runs through commercial accounts.

For an office of 20–40 people, the honest options are a mid-range super-automatic ($800–2,000) that grinds and brews at the push of a button, or a semi-automatic plus a proper burr grinder if someone on the team actually wants to learn. The grinder matters more than the machine. A $600 machine with a $400 grinder beats a $900 machine with a $60 blade grinder every single time, and it isn't close.

Step 7: Match the Water to the Machine

Here's where steps 1 through 3 come back around. Most consumer and prosumer espresso machine warranties specify a water quality range — total hardness, alkalinity, and pH. Void those and you void the warranty, usually without realizing it until the boiler scales up or the sensors start misreading.

Two failure modes I've seen:

Too hard. Scale builds on the boiler and the group head. Descale intervals shrink from yearly to monthly. Filtered water reduces the carbonate hardness that causes this — that's the specific job a carbon-based jug filter does, and it does it reasonably well for a countertop setup.

Too pure. Reverse-osmosis or distilled water is a common overcorrection. It has almost no mineral content, which makes some machines' water sensors behave oddly and, depending on the manufacturer, can be explicitly excluded from warranty coverage. Espresso machine makers generally want water with some mineral content, not zero.

So: filter for taste and scale, but don't strip the water to nothing. And if your building's water is genuinely bad, get a proper under-sink system with a spec sheet you can hand to the machine's service tech.

Handover Walkthrough

Before you hand the space over, run this in one pass:

• Filtered water running clear, cartridge indicator reset, and a spare cartridge in the cupboard
• Faucet-mount filter seated with no drips at the aerator — run it hot and cold to check
• Kettle filled, boiled, and poured once; temperature presets confirmed working
• Stove on its dedicated breaker, griddle heated and cooled once, ventilation running
• Espresso machine on filtered water, backflushed, and a written note taped to it listing the water source
• A physical printout of who to call when something breaks

That last one sounds trivial. It isn't. The single biggest post-handover problem is that nobody knows who owns maintenance.

Mistakes I See Most Often

Buying filters without testing the water. Most common, most expensive.

Ordering a faucet filter for a pull-out faucet. Return shipping on a $40 item costs more in time than the item costs in money.

Treating the stove as an appliance instead of an electrical install. This is the one that actually delays a Monday opening.

Skipping the first-flush ritual on new cartridges. People taste the carbon dust, decide the filter is defective, and return a perfectly good unit.

One more, on disposal. Spent filter cartridges and plastic housings aren't automatically kerbside-recyclable, and packaging claims about recyclability have a legal floor: under the FTC's Green Guides (16 CFR Part 260), a product marketed as recyclable should be recyclable in areas where at least 60% of consumers have access to the relevant facility. Worth checking before you tell forty new employees to toss them in the blue bin. Verify current requirements with your local waste authority.

Two days, one electrician, and about $600 in equipment. That's the whole job, if you do it in the right order.
