Stop Overpaying: Distilled Water Costs $0.13–$0.60/L in Canada

Distilled water typically runs $0.13 to $0.60 per litre when bought in small retail bottles, with bulk containers dropping that to well under $0.30 per litre once you factor in deposits and delivery. If you only need a jug now and then, retail shelf prices offer simplicity. If you go through several litres a week, whether at home or in an office, scheduled delivery or a refill program almost always beats repeat retail trips on both price and hassle.

TL;DR:

• Bulk delivery of 11 to 18 L jugs can reduce the per-litre cost to as low as $0.13 to $0.30, making it more economical for regular use compared to retail bottles.
• Retail prices for small bottles range from $0.13 to $0.60 per litre, with higher costs for containers under 1 liter, making them best suited for infrequent, small-volume needs.
• Home distillation is generally only cost-effective for heavy, consistent daily demand, once the unit, electricity, and maintenance costs are factored in.
• Delivery services with flexible scheduling and transparent pricing tend to be cheaper than weekly retail purchases for regular users, especially when considering deposit refunds and reusable bottles.
• When evaluating costs, consider total project expenses, including delivery fees, deposits, and your time, rather than relying solely on shelf price.

How much does distilled water cost by container size?

Shelf price depends heavily on how much water is in the bottle and where you buy it. Smaller containers generally cost more per litre due to packaging and convenience costs.

Here’s how the common sizes typically break down:

• 500 mL to 1 L bottles: often priced higher per bottle, resulting in higher cost per litre. This pricing makes them suitable primarily for occasional, small-volume needs like topping up a steam iron.
• 1.5 to 4 L jugs: generally cost moderately per jug, with per-litre prices varying based on retailer and region. Some listings offer 4 L jugs at relatively low prices, reducing average costs.
• 10 L containers: typically fall into a mid-range price category between grocery convenience and bulk pricing, with moderate per-litre cost.
• 11 to 18 L (roughly 5-gallon) bulk jugs: typically $10.00 to $25.00 per delivery or refill, which can bring the per-litre cost down to $0.13 to $0.30 once you spread the per-litre and per-gallon pricing across the full container.

Prices shift with the season, too. Demand for distilled water climbs in the winter months when humidifiers and CPAP machines run more often, and some retailers nudge prices up during that stretch. Store brand versus name brand also matters more than most shoppers expect. A no-name jug and a premium-labelled one can hold the exact same purity grade, with the price difference coming entirely from packaging and marketing.

Is it cheaper to buy distilled water or make it yourself?

The honest answer depends on how much you use and how much your time is worth. Comparing options fairly means looking past the sticker price on a single bottle.

Three costs matter more than the shelf price alone:

1. Per-unit cost. This is the price per litre once you’ve already got the water in hand. It’s the number printed on the shelf tag or delivery invoice.
2. Total project cost. This adds delivery fees, how often you order, and the deposit you paid on the container, divided out over how many times you’ll reuse it.
3. Time and effort cost. Driving to the store weekly, hauling jugs, or babysitting a countertop distiller all cost something, even if it never shows up on a receipt.

At the low end, retail bottles work fine for occasional use like topping up a small appliance a few times a month. At the high end, bulk delivery services typically bring the per-litre price down toward $0.13 to $0.30, especially once you account for rules of thumb around volume discounts. Home distillation can pay for itself only under fairly heavy, consistent daily use, since the unit itself, the electricity, and ongoing maintenance need to be weighed against what a countertop distiller’s actual payback period looks like in practice.

Pro Tip: If you’re not sure which category you fall into, track how many litres you actually go through in a typical month before comparing prices. Most households underestimate their real usage by a wide margin.

Where can you buy distilled water, and which option fits your needs?

Every buying channel trades off price against convenience differently, and the right one depends entirely on how much water you go through.

• Grocery and big-box retail: widely available, no commitment required, but per-litre cost is the highest of any channel and you’re stuck making the trip yourself.
• Refill stations: often cheaper per litre than pre-bottled retail, but you need to bring your own containers and check that the machine’s output actually meets distilled-grade purity, not just “purified.”
• Scheduled delivery services: lower per-litre cost at volume, no store trips, and predictable billing, though most charge a refundable bottle deposit and may have delivery frequency minimums.
• Direct commercial suppliers: built for offices, clinics, and businesses ordering consistently, usually with account-based pricing rather than one-off purchases.

Before committing to any channel, check three things: the deposit policy, whether there’s a delivery fee on top of the water price, and whether the water is labelled suitable for sensitive uses like CPAP machines or humidifiers. If convenience matters more than shaving pennies off each litre, delivery or a refill station usually wins. If price is the only variable, retail bulk jugs bought in person will always be marginally cheaper before you factor in your own time.

How do you calculate your true monthly distilled water cost?

The math is simpler than it looks, and running it once tells you exactly which buying route makes sense for your household or office.

Start with the base formula:

1. Price ÷ litres = per-litre cost. For example, a jug priced at a certain dollar amount holding multiple litres results in a computed per-litre cost.
2. Add delivery fee ÷ deliveries per month. Delivery fees distributed across frequent deliveries add a smaller per-delivery cost.
3. Add deposit ÷ reuse cycles. A refundable deposit spread across reuse cycles adds a minor per-use amount once bottles are reused regularly.

A single household buying a moderate volume jug monthly at typical prices pays a per-litre cost typical for retail purchases.

A small office receiving regular large-volume deliveries with deposit fees amortized achieves a similar or somewhat reduced effective per-litre cost. This gap narrows with increased delivery frequency and bottle reuse.

Why scheduled delivery makes sense for regular users

Retail trips work fine until your usage climbs, and that’s exactly where a delivery model starts pulling ahead on convenience and predictability. Capital Flow, operating as Purity in Motion, delivers distilled water to homes and businesses across Ottawa and the National Capital Region, sourcing from trusted partners to keep the product consistent from one delivery to the next.

The delivery schedule adjusts to how much water you actually use, not a rigid contract. You can choose weekly, biweekly, or monthly drops, and there’s no long-term commitment locking you into a plan that no longer fits your household or office. That flexibility matters most for businesses with seasonal demand swings, like clinics that see more foot traffic in cold and flu season.

Pricing stays transparent throughout. There are no hidden charges buried in the invoice, no surprise fuel surcharges, and no fine print that changes the number you were quoted. For anyone who has been burned by a delivery service that adds fees after the fact, that predictability alone often justifies the switch.

Which option actually saves you money?

The math almost always favours the same pattern: retail for rare, small needs; delivery or refill for anything regular; home distillation only if your daily demand is genuinely heavy. Most people overestimate how often a distiller will pay for itself and underestimate how much their own time is worth driving to the store every week. Plastic waste is a real cost too, even if it never shows up on a receipt. If you do go with delivery, ask about the return and deposit process up front. A service that makes bottle returns easy is one that’s thought through the whole cost equation, not just the sale.
