TOTO Washlet C5 vs BioBidet BB-2000 Bliss
Winner: BioBidet BB-2000 Bliss
In the Bio Bidet vs TOTO matchup, the BioBidet BB-2000 Bliss is the buy for almost everyone as of September 2026, and the reason has changed. TOTO discontinued the Washlet C5 in favor of the S5, so the C5 now sells from thinning retailer stock at roughly $624 and up, above the BB-2000's $549 list price. The Bliss is cheaper, still in production, carries a 3-year warranty against the C5's 1-year, and wins on wash features with unlimited hybrid warm water, a vortex massage spray, and an LCD remote. Buy a C5 only if you find leftover stock under about $450 and you specifically want TOTO's PREMIST and eWATER+ hygiene tech. If you want a current TOTO, compare the Washlet S5 instead.
The TOTO Washlet C5 and BioBidet BB-2000 Bliss are two of the most researched electric bidet seats in the mid-range to premium segment, and "Bio Bidet vs TOTO" is one of the most common matchups shoppers bring us. Both offer heated seats, warm water wash, warm air dryers, deodorizers, and self-cleaning nozzles. One thing has changed since we first published this comparison: TOTO has discontinued the C5 and replaced it with the Washlet S5, so C5 pricing now depends on which retailer still has stock. Prices below were checked in September 2026. Here is how the two seats compare on water heating, wash modes, remote control, warranty, and total cost of ownership.

Which One Is Right for You?
Choose TOTO Washlet C5 if...
Get the TOTO Washlet C5 only if you find remaining stock on clearance, ideally under about $450, and you specifically want TOTO's PREMIST bowl pre-mist and eWATER+ wand sanitization. Its 403W draw is the right answer for a bathroom on a crowded circuit, and there is no filter to replace. Go in knowing the seat is discontinued and carries only a 1-year warranty. If you want TOTO hygiene tech on a current model instead, price the Washlet S5.
Check TOTO Washlet C5 PriceChoose BioBidet BB-2000 Bliss if...
Get the BioBidet BB-2000 Bliss in every other case, which right now is most cases. At $549 it undercuts the closeout C5, it is still in production with a 3-year warranty, and it gives you unlimited warm water, a wireless LCD remote, and the pulsating vortex massage spray that makes it our pick for hemorrhoid relief and sensitive users. It is also the only one of the two available for a round toilet.
Check BioBidet BB-2000 Bliss PriceOur Verdict
This Bio Bidet vs TOTO comparison used to be a straight price-versus-features tradeoff. It is not anymore. TOTO retired the Washlet C5 in favor of the Washlet S5, and what is left in the channel is closeout inventory. When we checked in September 2026, authorized bidet retailers listed the C5 between about $624 and $717 where it was in stock at all, with a $780 list price and several stores showing sold out or "discontinued, see the S5" notices. The BB-2000 Bliss, still in production, lists at $549 direct from Bio Bidet. The seat that used to be the value pick is now the more expensive one, and the gap runs the other way. On the hardware itself, the BB-2000 Bliss leads where it always did. Its hybrid on-demand heating means warm water never runs out mid-wash, the patented 3-in-1 stainless steel nozzle delivers posterior, feminine, and vortex massage sprays, and the oscillating wash mode gives wider, gentler coverage that hemorrhoid sufferers tend to prefer. The wireless remote with its LCD screen lets you adjust settings without reaching behind you, the blue LED nightlight helps on late-night trips, and the Bliss comes in round as well as elongated. The 3-year warranty is triple the C5's coverage, which matters more than usual when the alternative is a discontinued unit. The C5 still has two real advantages. TOTO's PREMIST bowl pre-mist and eWATER+ electrolyzed-water wand sanitization have no equal on the Bio Bidet, and at 403W the C5 draws a third of the BB-2000's 1200W peak, so it is friendlier to a shared bathroom circuit and cheaper to run. It also has no replaceable filter, while the Bliss wants a roughly $20 deodorizer filter each year. The cost math no longer rescues it, though. At $624 versus $549 the C5 starts $75 behind, and its lower running costs only claw back about $65 over five years: roughly $834 of total ownership for the C5 against $919 for the BB-2000. That $85 five-year edge is not worth buying into discontinued stock with a 1-year warranty and no guarantee of parts. If you do stumble onto a genuine C5 clearance deal under about $450, the value argument comes back and it is a fine seat to own. So the September 2026 answer: buy the BioBidet BB-2000 Bliss. Buy a C5 only on clearance, and if what you actually want is TOTO hygiene tech on a current model, look at the Washlet S5, which adds the tankless heater and a slimmer seat for around $682.
