Got a quote from another company but you’d rather use us? Give us a call and we’ll work with you. We can’t move much, but we’ll sure try. Second opinions are always free.
Seeing a price that seems too low? Some companies use loss leaders, a cheap price to get in the door. Some prices only make sense when nobody’s in the office and nobody answers the phone. With us, a live person answers, and you can text us too.

Online special5-stage, high-efficiency 1:1 reverse osmosis system, installed by a Desert Water plumber, with your choice of faucet: matte black, chrome or brushed nickel.

Toilet installs start at $265, and the fancier the toilet, the more it costs. We’ve installed some for over $1,000. We’ll supply a Kohler Highline toilet with delivery, haul-away and everything else for $685. A Toto is $1,385. Or we can quote installing the toilet you already have. We warranty our work either way, and we only warranty the parts when we supply them.

$265 to $365 for most standard faucets, quoted by phone. Fancy or cut-out faucets get a written bid, because the work changes. A cluttered or dirty work area adds time, and we say so up front.

Most standard shower and tub cartridges replaced by a professional run $385 to $685, usually somewhere in the middle. We quote on site because the valve, the brand and what’s behind the wall change the job. If the cartridge can’t be fixed, we can usually put in a new valve with standard trim for $785 to $1,250. Fancier trim is available, but it’s hard to quote online. We keep the common Delta, Moen and Pfister cartridges on our trucks and in our warehouse. Part of the price is being ready for the call and having the right parts on the truck when it matters most. We can special order just about anything fancy. If it isn’t one of those, expect a bid for the follow-up visit. Same-day isn’t realistic without a lot of driving around and extra cost, and that’s negotiable on site. We work on Delta 1300, 1400 and 1700 series valves, Moen 1222 and 1255 cartridges, Pfister Avante, Kohler and Symmons, including thermostatic and volume-control valves.
