What is Southwest Plumbing Supply?
Southwest Plumbing Supply (SWPS) is a family-owned wholesale plumbing, waterworks, HVAC and irrigation supplier founded in Cedar City, Utah, in 1989 by Garth O. Green, a former commercial banker. Its main counter is at 690 N Main St in Cedar City, with separate sprinkler and heating-and-cooling counters in town and branches in Price, Ephraim, Springville and Mesquite, Nevada.
The company says it serves all of Utah, Northern Arizona and Eastern Nevada. It is still run by the founding family, sells online at swplumbing.com, and keeps a Kitchen & Bath Distinctions showroom for people who want to see fixtures before ordering. Plumbers in Cedar City and across Iron County are its core customers; St. George has no branch, which the questions below cover.

Can a homeowner buy at Southwest Plumbing Supply, or is it contractors only?
Southwest Plumbing Supply says its target market is the professional contractor, and it runs contractor bids and credit accounts, but it publishes no trade-only rule. Its website invites anyone who needs to replace a toilet or install a kitchen sink, sells online to registered customers, and its showroom is open to homeowners. If you are not a contractor, call (435) 586-6464 before you drive over.
- Contractors: the site has a contractor bids login and a downloadable credit application, so account customers get bid pricing and terms.
- Homeowners: the company's own words are that its parts and staff help "whether you need to replace a toilet, winterize your sprinkler system, or install a new kitchen sink." Expect counter service aimed at the trade: know your model numbers or bring the old part.
- Online: swplumbing.com ships web orders, with free economy shipping on orders over $1,000 and half-price shipping over $500 (toilets, water heaters and tubs go by freight and are excluded). Returns need an RMA number first or carry a 20% restock fee.
- Showroom: the Kitchen & Bath Distinctions showroom, opened in 2009, is where designers, contractors and homeowners can see fixtures in person.
What does Southwest Plumbing Supply stock?
Four lines: plumbing (fixtures, faucets, water heaters, rough-in and repair parts), waterworks (valves, hydrants and fittings for water and sewer mains), HVAC (furnaces, air conditioners, venting and fireplaces through its Cooling Heating Supply counter) and irrigation (sprinkler heads, controllers and pipe through its Sprinkler Supply counter), plus pipe tools.
Brands the company lists on its site include American Standard, Bradford White, Brizo, Delta, Elkay, Gerber, Grohe, Hansgrohe, InSinkErator, Kohler, Moen, Pfister, Rheem, Sloan, Toto, Watts, Zurn and Wilkins, with Rain Bird and Toro for irrigation and Ridgid, Milwaukee, Makita, Malco and Reed for tools. Its chamber of commerce profile adds American AVK, EBAA Iron and A.Y. McDonald for waterworks, Weathermatic and K-Rain for irrigation, and Vermont Castings, Monessen and Blaze King fireplaces.
For a homeowner the useful categories are water heaters (tank and tankless), water softeners and filtration, which matter in Southern Utah's hard water, and the repair parts that keep an older faucet or toilet working instead of replacing it.
How is Southwest Plumbing Supply different from Home Depot, Lowe's and Ferguson for a homeowner?
Home Depot and Lowe's are retail stores open seven days with the lines made for retail shelves. Southwest Plumbing Supply is a wholesale counter: it stocks the professional lines plumbers install, such as Bradford White water heaters, and the parts to repair them, but closes at 6 p.m. weekdays and 2 p.m. Saturday. Ferguson is the national wholesaler with a St. George branch; SWPS is the locally owned one in Cedar City.
| Option | Who it is built for | What that means for you |
|---|---|---|
| Southwest Plumbing Supply (Cedar City) | Plumbers and contractors; homeowners welcome to ask | Professional lines, repair parts, counter staff who work with plumbers daily; weekday and Saturday morning hours; no St. George branch |
| Ferguson (St. George) | Plumbers and contractors | National wholesaler with a St. George branch and showroom network; same trade orientation as SWPS |
| Home Depot and Lowe's | Homeowners and DIY | Retail product lines, long hours seven days a week, easy returns; fewer professional-grade parts |
| Your plumber | You | Most plumbers supply the parts for the job from a wholesaler and warranty the install; compare quotes on our St. George plumbers page |
