#2 in our rankings · Best value electric
TOTO Washlet C2
Best for: Buyers who want genuine TOTO cleaning and heating at the lowest electric-seat price.
#7 in our rankings · Best non-electric
Brondell Swash EcoSeat S101
Best for: Renters and budget buyers who want a proper bidet seat without wiring.
Our recommendation
Buy the TOTO Washlet C2 if you have an outlet nearby and want heated water, a heated seat, a dryer, and a deodorizer. Buy the Brondell EcoSeat S101 if you have no outlet, rent, or want bidet washing for the least money and fuss. The wash itself is good on both; everything else is the difference.
Comfort features
The C2 heats the water and the seat, dries with warm air, and deodorizes the bowl area. The S101 does none of that: it washes with room-temperature water and leaves drying to paper. In winter, that gap feels large.
Install and requirements
The S101 needs only a T-valve and basic tools, with no electrical work at all. The C2 needs a GFCI outlet within cord reach, which can mean an electrician in older bathrooms.
Price and running cost
The S101 costs a fraction of the C2 and has no running cost beyond water. The C2 costs more upfront and uses a small amount of electricity for heating and standby, though the amount is modest.
Choose TOTO Washlet C2 if…
- You have a GFCI outlet near the toilet
- Heated seat and warm water matter to you
- You want a dryer to cut paper use sharply
Choose Brondell Swash EcoSeat S101 if…
- You have no outlet near the toilet
- You rent and want a reversible install
- Lowest price and simplest ownership matter most

Strengths and limitations
TOTO Washlet C2
Strengths
- Side arm panel keeps every control at hand with no remote to lose, charge, or wall-mount, which suits guests and less tech-confident users.
- PREMIST and EWATER+ carry over from the C5, so bowl and wand hygiene are not cut to hit the lower price.
- Heated seat, air deodorizer, and warm air dryer with three temperature settings each keep the comfort set intact.
Limitations
- No remote and no user presets, so a two-person household resets preferences by hand each time.
- Same tank-fed warm water as the C5, so very long washes cool off near the end.
- Arm panel adds bulk on one side, which can crowd a tight bathroom layout.
Brondell Swash EcoSeat S101
Strengths
- Full seat replacement with dual nozzles for front and rear wash, plus a slow-close seat and lid, so it feels like a real upgrade rather than an add-on.
- Quick-release button lifts the seat off for cleaning, solving the awkward scrubbing that fixed seats suffer from.
- No power needed and a simple T-valve install mean most owners fit it in under half an hour with basic tools.
Limitations
- Ambient-temperature water only, which feels bracing in winter and in cold-water homes.
- No dryer, so paper use drops but does not disappear.
- Pressure control is a simple dial, with less fine adjustment than electric seats offer.

Questions, answered
Is the S101 wash as clean as the C2 wash?
For cleaning, yes: both deliver an adjustable water wash that beats paper. The C2 adds comfort around that wash, not cleanliness itself.
Can I upgrade from the S101 to the C2 later?
Yes, the T-valve and seat mounting are similar, so swapping later is straightforward once an outlet is available. Many owners start non-electric and upgrade.
