TOTO WASHLET S5 Bidet Seat vs Brondell Swash S300 Electric Bidet Seat

Buy the TOTO WASHLET S5 if you want a full-featured seat with a warm air dryer, automatic deodorizer, and a remote that docks to the seat. Buy the Brondell S300-RW if your toilet is round and you want the core comforts — heated seat, warm water, dual stainless nozzles — for less complexity. The TOTO is the better-built, more complete unit and its 4.7 rating from 374 owners backs that up; the Brondell scores 4.5 from 93 ratings and is the simpler, round-only option.

  • Choose the TOTO WASHLET S5 if your toilet is elongated and you want a dryer, deodorizer, and docked remote in one unit.
  • Choose the Brondell S300-RW if your toilet is round and you mainly want a heated seat and warm water wash without extra features.

Questions and answers

Which is better for a round toilet?
The Brondell S300-RW. It is built for round bowls, while the TOTO S5 is elongated only.
Does the Brondell have a dryer?
No. The Brondell S300-RW has a heated seat and warm water wash but no warm air dryer. The TOTO S5 does have one.
Which feels more solid?
Both use plastic seats. The TOTO has the higher owner rating and adds a docking remote and deodorizer, which most owners treat as the more complete unit.
Is the TOTO worth stepping up to?
If your bowl is elongated and you want a dryer, deodorizer, and docked remote, yes. If you only want warm water and a heated seat, the Brondell covers that.
Do both have self-cleaning nozzles?
Yes. The TOTO uses EWATER+ cleaning, and the Brondell uses self-cleaning stainless steel dual nozzles.
