A Colorful Showerhead Built a 3.9 Million Dollar Business and the Filter Made It a Subscription

The aisle nobody was excited about

Walk the plumbing aisle of a hardware store and the message is clear: chrome, silver, and more chrome. Benjamin Fix spent years working in plumbing and noticed the industry had decided bathrooms should have all the personality of an office printer, as The Hustle Blower tells it.

Fix also noticed who was being ignored. Young renters wanted stylish homes, but bathroom products assumed they owned the place. A renter will not renovate a bathroom they do not own. They might buy something colorful, practical, and easy to install. In November 2022, Fix and fellow plumbing veteran Greg Reinecker launched sproos, with Cecile Scius leading customer success and community, after raising about 250,000 dollars from friends and professional contacts.

Made to be understood at a glance

Sproos made showerheads in pink, green, and other bright colors, designed to look like home accessories rather than hardware. The company sent products to lifestyle creators on Instagram and later TikTok, aiming at college students and apartment renters.

The pitch needed no contractor, no renovation loan, and no landlord permission. If people can understand the value in a five second video, the story tells itself. But a showerhead has a built in limit: one person needs one, maybe two, and then the company must find the next customer.

Customers pointed at the real business

Four times a year, sproos holds roundtable conversations with loyal customers and asks what they like, what annoys them, and what they wish existed. Those conversations led the company to shower filtration. Customers wanted a better shower experience, not just a better looking one.

The company spent about two years developing a filtration product. The bigger discovery was the replacement cartridge. A filter needs changing regularly, in the sproos case every three months, so the company could offer a subscription that solves a real chore instead of inventing a reason to bill people.

35,000 subscribers change the math

By October 2026, sproos reported about 35,000 active filtration subscribers. About 70 percent of new customers choose the subscription option, and reported monthly subscriber churn is below 3 percent. The company generated 3.9 million dollars in revenue in 2025 and, in an October 14, 2026 interview, said it was on track to pass 10 million dollars in revenue this year.

That 10 million dollar figure is a projection, not a finished result, and revenue is not profit. Manufacturing, inventory, shipping, and marketing still get paid. The lesson is the shape of the model. A product sold once must be sold again to a stranger. A needed replacement sells again to a customer who already trusts you, which makes demand easier to plan around.

A tiny washer and the right shelf

Not every customer insight produced a product. When leaks were reported, engineers traced the problem to a tiny transparent washer that could slip off the hose. The company modified the mold, adding a small lip to keep the washer in place. For a subscription business, a small defect is expensive, because frustration turns into cancellations.

Growth followed the same listening pattern. Sproos expanded through Amazon and into HomeGoods, a retailer its own customers said they liked shopping at, and ran pop up events with student housing company Greystar that the company says raised local sales by 200 percent. The founders were not trying to be everywhere. They were showing up where their customers already were.

Borrow the model, skip the plumbing

You do not need a plumbing brand to use the sproos playbook. The moves translate to almost any product or service business:

• Find a boring category that is ignoring a clear group of buyers
• Make the improvement easy to understand at a glance
• Look for the repeat purchase hiding behind the first sale
• Ask customers what frustrates them, then fix the small thing before it costs you subscribers
