Owner's Manual


  • Made of high-quality components, the Swash ecoseat has no need for T-valves that need to be shutoff with every use, delivering peace-of-mind from leaking and flooding.  

  • For over 14 years Brondell has specialized in bidets – making bidet toilet seats, bidet attachments, bidet sprayers, and travel bidets. Brondell offers the most possible features without ever compromising product integrity. With Brondell you are making the best choice possible for overall product quality, features, value, and – most importantly – support. The Swash ecoseat is backed by Brondell and their industry-leading Customer Support based in San Francisco, CA.

  • Manufacturing toilet paper is an exceedingly wasteful process. It requires a far greater amount of water than is required for regular bidet seat use.

  • One small change to your bathroom habits reduces your toilet paper use 50%–100% and saves not only water, but also the trees and power used in toilet paper production.

    Plus, less toilet paper means fewer clogged toilets!

Great Product and Service

I purchase two of these to put in our Mountain house. Michael was very helpful in promptly answering questions. After a couple weeks, my wife insisted we put these in our main house as well. I decided at the last minute to surprise her and have them installed when she came home from a business trip. Michael helped again by getting my shipment out quickly. Love, love Love, the towel warmers, and would absolutely order from Only Towel Warmers again!

Great experience

Warmer was as pictured. Great ordering and delivery service. Would purchase from them again!

Excellent product and service

I purchased one of these for a bathroom addition, in response to the positive reviews of both product and service on the website. I then decided to purchase a second warmer for an existing bathroom. On both occasions, Michael was very helpful in responding to questions and for the second device , he supplied extr brackets to fit our needs (covering over holes from prior towel bar).
I’m very satisfied with the product and the service provided and would not hesitate to use this firm again.

Terrific merchant, great products

My wife and I recently moved into the first house we had ever had designed and built. We sourced all of our bath accessories (towel bars, towel warmers, etc.) from Only Towel Warmers, and we have rarely had such a good experience with a web business. The product quality (Volcano and Artos) is top-notch and beautiful, and the help we got from Michael was fast and complete. We are very hap[py customers!

Beautiful and as expected!
