Bath and Bag started in a cramped Brooklyn kitchen with a $69 immersion circulator clamped to a stockpot balanced on a stack of cookbooks. That was 2018, and what began as one home cook's obsession with hitting the perfect 131°F medium-rare has grown into a dedicated resource for sous vide and precision cooking enthusiasts across the country.
Our Founding Story
Bath and Bag was founded by Marcus Whitfield, a former restaurant line cook turned software engineer who never quite left the kitchen behind. After a decade in professional kitchens, Marcus wanted to bring restaurant-level precision to home cooking without the restaurant-level chaos. He bought his first sous vide machine to solve a simple problem: overcooked chicken breast. He never looked back.
What he found, though, was a landscape of confusing product claims, inconsistent testing, and marketing copy dressed up as reviews. Bath and Bag was built to fix that. Marcus started documenting his own testing — water displacement bag setups, temperature calibration checks, container compatibility — and sharing it publicly. Readers responded. Within two years, a small team of cooks, testers, and writers had joined him, each bringing their own kitchen background, from pastry to butchery to culinary school instruction.
Today, Bath and Bag is run by that same core team: people who cook for a living, test for a living, and genuinely enjoy arguing about whether a $40 vacuum sealer can compete with a $200 chamber sealer. It can, sometimes. We tell you when.
How We Review and Pick Products
Every product featured on Bath and Bag goes through a hands-on testing process before it earns a spot in our recommendations. We don't rely on spec sheets or manufacturer claims alone. Our process includes:
- Real cooking tests. We run each immersion circulator, water oven, or vacuum sealer through actual multi-hour cooks — steaks, eggs, chicken, root vegetables, and long-format proteins like short rib and pork shoulder.
- Temperature accuracy checks. We verify claimed temperatures against calibrated reference thermometers, checking for drift over extended cook times.
- Noise and heat-up time measurements. Because a circulator that sounds like a dishwasher or takes 40 minutes to reach temp affects your daily cooking experience.
- Build quality and clamp testing. We test how securely units attach to different container shapes and sizes, and how they hold up after repeated use.
- Bag and sealer performance. For vacuum sealers and bags, we test seal strength, liquid handling, and compatibility with the water displacement method for those without a sealer.
- Long-term use, not just unboxing. Where possible, we keep products in rotation for months, not days, to catch reliability issues that first impressions miss.
We also weigh value for money heavily. A great product at an inflated price doesn't get our recommendation over a slightly humbler option that performs just as well for less. Our rankings reflect real-world cooking performance, not affiliate payouts or brand relationships.
What Makes Bath and Bag Trustworthy
We buy the vast majority of products we review at retail price, just like our readers do. When we do accept a review sample, we disclose it clearly, and it never influences our conclusions — plenty of sent products have received lukewarm or critical reviews from us. If a manufacturer doesn't like what we wrote, that's not our problem to solve.
Bath and Bag may earn a commission when you buy through links on our site. This never affects our rankings, our opinions, or which products we choose to feature. We'd rather lose a commission than mislead a reader into buying the wrong immersion circulator for their kitchen.
We update our guides regularly. Sous vide technology doesn't change dramatically year to year, but new models, price changes, and discontinued products do, and we go back into old content to keep it accurate rather than letting it sit stale.
Who's Behind the Reviews
Our contributors include former line cooks, a culinary instructor, a food scientist with a soft spot for immersion circulators, and home cooks who simply refuse to eat another dry piece of salmon. Every reviewer on the team has logged real hours cooking sous vide at home and professionally, and every piece of content is edited for accuracy before it's published.
Whether you're buying your first sous vide setup for under $100 or building out a serious home precision-cooking station, our goal is the same: give you the straight, tested truth so you can cook with confidence and skip the guesswork.
Thanks for reading, and thanks for trusting Bath and Bag with your kitchen decisions.
