What owners say
Toto Washlet S5
- +Four user presets on the remote (up from two on the old C5) store position, pressure, and temperatures per person — the single best shared-bathroom feature at this price
- +Instantaneous heating ends the C5's notorious 35-45-second warm-water window; wash for five minutes straight and it never runs cold
- +Gained a bowl-illuminating night light the C5 never had — genuinely useful at 3 a.m. and one less reason to pay up for the S7 tier
- +EWATER+ sanitizes the wand with electrolyzed water before and after each use, and PREMIST keeps the bowl slick so waste doesn't stick
- +Heated seat spans 82-97°F across five settings, and the seamless seat molding has no crevice seam for grime to collect in — a real cleaning-day upgrade over the C5
- +Warm-air dryer adjusts 95-140°F — a wider, hotter range than the Brondell Swash 1400's famously tepid dryer
- −You're paying roughly $300 over the S2 for a remote and presets — the wash hardware underneath is otherwise identical
- −Several early owners note the seat sits tall with a slight forward slope ('feels like it's pushing you forward'), a byproduct of the 7.4-inch rear housing
- −The 1,271-watt draw needs a dedicated GFCI within reach of the 3.93-ft cord, and TOTO's manual warns against extension cords
- −The dryer, though adjustable, is still TOTO-gentle: plan on 1-2 minutes or a courtesy dab of paper where a Bio Bidet BB-2000 finishes in about 40 seconds
- −One-year warranty on a $650 seat, while Brondell backs the cheaper Swash 1400 for three years
- −MSRP is $780 and 'sale' pricing is perpetual — legitimate street price floats $570-670, so treat anything near list as a ripoff
Bio Bidet Discovery DLS
- +Motorized auto-open/close lid works reliably on approach — a headline feature usually reserved for $1,000+ seats like the Toto S550e
- +Tankless heating delivers genuinely endless warm water with no 30-second cliff, fixing the biggest complaint about the BB-1000/BB-2000 tank designs
- +At 4.7 inches tall in the rear it's Bio Bidet's slimmest seat, and reviewers say it finally looks like it belongs on a modern toilet
- +UV light sterilizes the stainless nozzle between uses — a hygiene extra even Toto reserves for its ewater+ premium models
- +5-year 100% parts-and-labor warranty is the best coverage in the category, beating the BB-2000's 3 years and Toto's 1
- +The warm-air dryer is notably stronger than the fan in the BB-2000 — one of the few bidet dryers reviewers say they actually finish with
- −Peak spray is softer than the pump-driven BB-2000 — owners coming from a vortex-wash Bio Bidet or strong Toto notice the step down in raw pressure
- −Reviewed.com's tester hit build-quality issues — inconsistent pressure and temperature and a visibly shaking nozzle — so QC seems less consistent than Toto's
- −Confirmation beeps can't be disabled, and the motorized lid is audibly noisier than competitors — annoying in shared or nighttime bathrooms
- −Elongated only; round-bowl owners are pointed back to the older BB-1000/BB-2000
- −The auto-open lid triggers on pets and passers-by in small bathrooms, and several owners end up turning the motion sensor off
- −No app support or user profiles at a price point where the Alpha JX and Brondell Swash 1400 offer programmable presets
