Inus
Inus R31
A Korean-made tankless value seat that built its reputation on Amazon, the R31 pairs on-demand heated water with a wireless remote, heated seat, bowl night light, and a well-tuned skin sensor. It skips the air dryer - that's the step-up R32's job - which keeps the price down and the profile slim. Inus sells it direct for $369 with frequent trade-in promos, while its Amazon presence now lives under the shared R-series listing.
Specifications
Features
Pros
- ✓Korean-built tankless system delivers consistent endless warm water - same core tech as seats $200 more
- ✓Wireless remote (with user presets) at a price where SmartBidet's SB-2600 makes you twist to a side panel
- ✓Skin sensor is unusually well-calibrated - owners note it never sprays unless someone is actually seated
- ✓Bowl-illuminating night light makes 3 a.m. visits glasses-free, a feature the SB-2600 skips
- ✓Stainless self-cleaning nozzle with auto and manual cleaning cycles resists buildup
- ✓Everything is adjustable: pressure, water temp, seat temp, nozzle position, steady vs. oscillating
- ✓Slim, elegant profile that owners say looks premium next to bulkier Bio Bidet units
- ✓Sub-30-minute DIY install with all parts included - no plumber needed
Cons
- ✗No air dryer at all - you must buy the R32 (about $300 on Amazon) if you want one, which undercuts the R31's value math
- ✗No deodorizer either, so it trails the Alpha JX2's feature list at a similar price
- ✗$369 direct price is high for a dryer-less seat; wait for Inus's frequent $100+ promos
- ✗Its dedicated Amazon listing has gone dormant - US buyers mostly purchase through theinushome.com now
- ✗Elongated only; no round version exists in the R series
- ✗1-year warranty and a small US support operation compared to Toto or Coway
- ✗Remote has no wall mount in some shipments, per owner complaints
- ✗Heated seat maxes out mild - cold-bathroom owners wish for a hotter top setting

Omigo
Omigo SL
A discontinued product walking. Omigo, the DTC bidet startup, was absorbed by Brondell in November 2023, and by mid-2026 the SL is effectively end-of-life: myomigo.com redirects to a Brondell outlet page, the Amazon listing is dead ('we don't know when or if this item will be back in stock'), and remaining units are outlet and open-box clearance. On paper it's still a strong seat — instant ceramic heater for endless aerated warm water, 7-position stainless nozzle, three spray widths, heated seat, night light, and remote at a $375 last-sold price.
Bio Bidet
Bio Bidet BB-1000 Supreme
The BB-2000's older, cheaper sibling and one of the longest-selling bidet seats in the US — still current in Bio Bidet's 2026 lineup at $359 list, often $299-340 on sale. It keeps the same pump-driven vortex wash and 3-in-1 stainless nozzle but swaps the hybrid heater for a simple tank, so warm water lasts about 30 seconds. A proven value pick if wash strength matters more than endless warm water.
Tushy
Tushy Cloud
Tushy's mid-tier electric seat, launched early 2025 as the bidet-attachment brand's serious move upmarket: ceramic-core instant heating for endless warm water, heated seat, warm-air dryer, night light, and UV nozzle sterilization, all run from a side console. A $399 Cloud+ trim adds a wireless remote and an automatic carbon deodorizer but is otherwise the same seat. CNN Underscored named the Cloud a top pick for undercutting typical $500 endless-warm-water seats.
