Houston's dedicated cold plunge & sauna service company.

The Cold Standard is Houston's dedicated cold plunge service company. We're not a pool company that also touches plunges, and we're not an HVAC tech guessing at water chemistry — cold plunges and saunas are the only things we work on. We serve the entire Houston metro including The Woodlands, Katy, Spring, Sugar Land, Cypress, Kingwood, Bellaire, River Oaks, Cypress, Pearland, League City, San Marcos, and Tomball.

Residential plans start at $169 every 4 weeks for our Essential plan (one full service visit per cycle). Premium is $299 every 4 weeks (biweekly visits plus quarterly deep clean). Weekly is $599 every 4 weeks for 52 visits per year ($150/visit effective) — the highest-density residential tier. Pay-as-you-go quarterly deep clean is $375 per visit if you handle weekly chemistry yourself, and a one-time deep clean is $399 flat for a single no-commitment service. Commercial plans (gyms, studios, hotels, spas) range from $279 every 4 weeks (Commercial Light) up to $999 every 4 weeks (Commercial Plus, twice-weekly visits). All recurring plans are month-to-month — cancel anytime.

Standard repair calls are scheduled within 48 hours of contact anywhere in the Houston metro. Premium plan members get priority 24-hour scheduling. Commercial accounts get same-day emergency response. Our route covers roughly a 40-mile radius around downtown Houston — from Spring and The Woodlands in the north to Pearland, League City, and San Marcos in the south, and out to Cypress and Kingwood in the Gulf Coast. Our service call is $170 flat — covers the trip out and a full diagnostic with a written estimate before any repair work begins. Repair labor is $185/hr with member discounts of 15–30%.

Every major brand on the Houston market: Plunge, BlueCube, Renu Therapy, Cold Stoic, Ice Barrel, Edge Theory Labs, Morozko Forge, Polar Monkeys, Nordic Wave, Kodiak, Inergize, Tru Grit, and custom-built units. If a brand isn't listed, we still service it — we work on the entire category, not specific OEMs.

Yes. We service saunas across the entire Houston metro — infrared, traditional electric (heater + stones), wood-fired, and steam rooms — for homes, gyms, and recovery studios. We handle wood-safe deep cleaning, heater and emitter service, electrical and controls repair, and recurring hygiene maintenance. All brands, including Sun Home, Clearlight, Sunlighten, Harvia, Finnleo, and custom-built rooms.

Our Sauna Tune-Up & Inspection is $149 flat — a wood-safe interior clean, heater/emitter inspection, electrical and controls check, and a digital report with photos. The Sauna Deep Clean & Wood Care is $249 flat — everything in the tune-up plus a full hygiene deep clean, sweat-stain treatment, paraffin bench treatment, and heater stone service. Sauna repair is a $170 service call (trip + first hour), then $185/hr. Commercial rooms and recurring hygiene plans are quoted per facility.

All of them — infrared, traditional, hybrid, and steam. That includes Sun Home, Clearlight, Sunlighten, Harvia, Finnleo, and custom-built rooms. We use only manufacturer-approved, wood-safe cleaners (never bleach, ammonia, or abrasives that damage cedar and hemlock or void your warranty), and we document every visit with photos.

Houston is a harder water market to protocol than most, because it is not one water. The City of Houston's own reporting puts average hardness around 137 mg/L, but it draws from several sources and some zones run past 230 ppm — so the chemistry that works in Sugar Land can be wrong in Kingwood. On top of that, Gulf Coast humidity keeps organic load high year-round: dew points sit in the 70s for months, biofilm re-establishes fast, and covers trap moisture instead of drying out. Cloudy water here is almost always imbalanced chemistry (pH out of the 7.2–7.6 range, low sanitizer), scale where the local supply runs hard, or biofilm in the filter and plumbing. We test your actual supply on the first visit rather than assuming a city average, run a sequestrant protocol only where the hardness justifies it, and rescue most water without a full drain.

Yes — commercial accounts are a core part of our book. We service gyms, recovery studios, boutique fitness facilities, chiropractor offices, med spas, hotels, and corporate wellness rooms across the Houston metro. Commercial plans include compliance-grade documentation (water test logs, chiller inspection records, photo before/after), annual staff training, and 30% off repair work. Facilities that run both plunges and saunas can bundle both under one vendor and one visit.

Every visit includes: water chemistry test (pH, free chlorine, total alkalinity, calcium hardness, temperature), chemical balancing and sequestrant dosing as needed for hard Texas water, filter inspection and cleaning or replacement, chiller and compressor health check, surface cleaning and biofilm prevention, pump and circulation inspection, and a detailed digital service report sent to you after we leave.

Yes. Initial setup, commissioning, and first-fill chemistry are handled by our team. If you've just purchased a plunge and need it set up correctly, we run a comprehensive initial setup visit that covers placement, electrical check, plumbing, first water fill and balance (with hard-water sequestrant dialed in), chiller commissioning, and a complete owner walkthrough.

Pool techs are trained on chlorinated 80°F+ water in large-volume pools/spas. Cold plunges run at 38–55°F with concentrated bather load and chiller equipment that pool techs aren't certified to touch (refrigerant work is EPA-regulated). The chemistry is different, the equipment is different, and the failure modes are different — and in Houston's heat, undersized chillers fail far more often than most pool techs expect. We do only this — cold plunges and saunas — that's why our reports, our parts inventory, and our diagnostic playbook all match the specifics instead of pool-spa generalities.

Yes — saltwater plunges (with salt-chlorine generators or natural-saltwater setups) require titanium or marine-grade heat exchanger inspection, more frequent gasket and seal checks, and different sanitizer-balance logic. We carry the right test kits and replacement parts for both setups, so brand doesn't matter — we calibrate the visit to your water chemistry and Houston's hard-water profile, not just the model number.
