TOTO Washlet vs Brondell Swash
Both make heated, warm-water bidet seats that bolt onto the toilet you have. They publish very different things about them.

| 1 |  WASHLET C5 Bidet Toilet Seat, Elongated A heated seat from 82 to 97°F, warm water from 95 to 104°F, a bowl pre-mist and an illuminated remote. | Knowing exactly how warm it gets | Ask first | |

What each brand tells you
Put the two product pages side by side and they answer different questions. TOTO gives you the experience in numbers: how warm the seat gets, how warm the water gets. Brondell gives you the machine: how the water is heated, what the nozzle is made of, how big and heavy the seat is.
Neither is hiding anything obvious. But the gaps are different, and which gap matters depends on what you are worried about.
Temperatures
TOTO publishes a seat range of 82 to 97°F and a water range of 95 to 104°F for the C5. Brondell publishes that its seats are heated and its water is warm, without ranges. If you have a reason to care about the exact figures — sensitive skin, or a household member who feels the cold — TOTO gives you something to go on.
How the water is heated
Brondell says both Swash seats here use a tank heating system: a small reservoir kept warm. We could not confirm the C5’s method from the TOTO sources we could reach. Tank against instant heating is explained here.
Nozzle and cleaning
Brondell publishes a stainless steel nozzle that self-cleans before and after each wash. TOTO publishes PREMIST, which mists the bowl before use, and describes its spray as aerated, warm and dual action. Keeping any nozzle clean is covered here.
Controls
The C5 uses a remote with an illuminated touchpad. The SE400 uses a side-arm panel. A remote is easier to reach and keeps the seat slimmer; a side panel cannot be lost.
Warranty and power
Both brands publish one year: TOTO from the date of purchase for the C5, and Brondell’s one-year limited warranty on both Swash seats. Both need an outlet within cord reach of the toilet, and neither should run from an extension cord in a bathroom. If there is no outlet, this is the other route.
A note on our sources
TOTO’s website blocked our direct requests, so the C5 figures above are quoted from TOTO’s own specification sheet and instruction manual as published on totousa.com. Where we could not confirm a figure, we say so rather than fill it in.
If you rent
All three rate Ask first on our install rating: the seat goes on the existing bolt holes and comes off again, but the outlet is a landlord conversation.
Every pick in full
3 we would buy. Each carries its Renter-Safe Install Rating, the published specs behind it, and the honest gap in what we know.
1. Best for published temperatures
WASHLET C5 Bidet Toilet Seat, Elongated
TOTO · SW3084 · best for knowing exactly how warm it gets
A heated seat from 82 to 97°F, warm water from 95 to 104°F, a bowl pre-mist and an illuminated remote.
The TOTO Washlet C5 publishes the numbers most bidet makers leave out: an adjustable heated seat with surface temperatures of 82 to 97°F (28 to 36°C), and warm-water spray adjustable from 95 to 104°F (35 to 40°C).
TOTO describes the wash as a “Gentle Aerated, Warm Water, Dual Action Spray”, and its PREMIST feature sprays the bowl before each use. Control is by a remote with an illuminated touchpad, and the warranty is one year from purchase.

- Time to fit

- Standard outlet — “AC 120 V 60 Hz”, on a “3.93 ft (1.2 m)” cord
- Reversible on move-out

Why: The seat goes onto the existing bolt holes and comes off again. The catch is the outlet it needs beside the toilet, which is a landlord conversation in most rentals.

What’s wrong with it
A one-year warranty, the same as Brondell's.
What we can’t tell you
TOTO's site blocked our direct fetch. We could not confirm the C5's water heating type, dryer or wattage from the TOTO sources we could reach.

2. Best for published hardware
Brondell Swash SE600 Bidet Toilet Seat
Brondell · Swash SE600 · best for knowing what is inside before you buy
Heated seat, warm-air dryer, tank heating and a self-cleaning stainless nozzle, with full dimensions.
The Brondell Swash SE600 publishes the other half of the picture. It has a “heated seat and adjustable warm air dryer”, a “tank heating system” for the water, and a “rust-resistant stainless steel nozzle” with a self-cleaning setting that runs before and after each wash.
Brondell also gives the size: 18.5 in. wide, 20.87 in. long and 6.10 in. high for the elongated version, 9.9 lb. That height is worth checking against your lid and tank. The warranty is one year.

- Power
- Standard outlet — the wattage and any GFCI requirement are not published
- Reversible on move-out
- Fully
Why: The seat itself swaps onto the existing bolt holes, so it is reversible. The catch is the plug: it needs a working outlet within cord reach of the toilet, and a lot of older bathrooms simply do not have one. That is a conversation with a landlord, not a drill.

3. Best for a known outlet distance
Brondell Swash SE400 Bidet Toilet Seat
Brondell · Swash SE400 · best for measuring to the outlet before you buy
Heated seat, tank heating, dryer and deodorizer, with a published 4-foot cord.
The Brondell Swash SE400 has one published detail the others lack: a 4-foot power cord at 120V / 60Hz. Measure from the toilet to the outlet and you know whether it will reach. It has a heated seat, tank heating, a dryer, a built-in deodorizer and side-arm controls.

- Standard outlet — Brondell publishes a 4-foot cord
- Reversible on move-out

Why: The seat swaps onto the existing bolt holes, so it is fully reversible. The constraint is the published 4-foot cord: measure from the toilet to the nearest outlet before you buy, and never bridge the gap with an extension cord in a bathroom.

What’s wrong with it
Side-arm controls rather than a remote.
