The DV-1S0019 is one of DeerValley’s most detailed product listings, and it’s the model I get asked about most often, so I went through the full spec sheet, the installation manual, and the pattern of complaints tied to this line to see if it earns its $659 price tag.
What it’s made of
The bowl is ceramic with a nano-glaze coating, paired with a polypropylene seat. It’s a tankless, one-piece elongated design rated at 1.28 GPF (4.8 liters) per flush, which is the same efficient-flush standard most modern low-flow toilets use.
The wash system covers posterior, feminine, and pulsating modes with adjustable pressure and temperature, run through a self-cleaning nano-antibacterial nozzle. Add-ons include a heated seat with a warm air dryer, a built-in deodorizer with filtration, an automatic lid, foot-sensor control, and an emergency blackout flush for power outages.
Specs and dimensions
| Overall size | 27.09″L x 16.57″W x 18.39″H |
| Weight | 100.24 lbs |
| Seat / bowl height | 16.50″ / 15.51″ |
| Rough-in size | 12″ (10″ version also available) |
| Weight capacity | 450 lbs |
| Warranty | 2 years, mechanical parts and bidet seat |
That rough-in size matters more than any feature on this list. A meaningful share of the negative reviews I found across DeerValley’s smart toilet line trace back to buyers ordering the 12″ rough-in version for a 10″ space, not to the toilet itself failing. Measure your existing rough-in before you order.
What buyers are actually saying
DeerValley’s own product page doesn’t display a star rating or review count for this specific model, which is a gap worth flagging rather than papering over. Pulling from the brand’s BBB complaint file and third-party retail reviews instead, the pattern across DeerValley’s smart toilet line looks like this: buyers who install correctly report genuinely satisfied long-term use, citing the heated seat, auto lid, and bidet functions as the standout features, with several reordering a second unit for another bathroom.
The recurring complaints are narrower than “the toilet doesn’t work.” They cluster around three things: installation kits missing a specific part, flush noise louder than a standard tank toilet, and a handful of cases where an advertised feature wasn’t active on the unit that arrived. DeerValley’s customer service responded to all six BBB complaints on record, and five of six were resolved.
Installation and what’s included
DeerValley ships the DV-1S0019 with the installation manual and mounting hardware included, and the listing notes it ships within 1-3 business days. Professional installation is recommended on the product page, which lines up with what I’d tell anyone buying their first smart toilet: this isn’t a drop-in seat replacement, it’s a full toilet swap with an electrical connection nearby for the heated and powered functions.
If you’re not confident on the plumbing side, budget for a plumber’s time on top of the unit price. That single step avoids most of the installation complaints I found in the BBB file.
How it compares
Inside DeerValley’s own catalog, the DV-1S0019 sits a step above the entry-level DV-1S0029 on finish and quiet-close hardware, at a similar price after discount. Against BCAN’s comparable tankless models, the feature set is close enough that price and current promotions usually decide it. I broke that comparison down fully in DeerValley vs BCAN.
Should you buy it
If you want a genuinely full-featured smart toilet (heated seat, bidet wash, auto flush, blackout backup) for under $700, the DV-1S0019 is one of the stronger picks in DeerValley’s lineup. Confirm your rough-in size before ordering, and budget for professional installation if you’re not doing the plumbing yourself.
