Frequently Asked Questions

Q. "Will these seats work with 220volts?"
A. These wonderful toilet seats require 120volts (standard AC) protected by a GFI (ground fault interrupter).

Q. "How do I know which washlet (bidet-style toilet seat) will fit my Toto toilet?"
A. If you have a one-piece Toto toilet, you will want to view the first chart. If you have a two-piece Toto toilet, you will want to view the second chart. Find the name of your toilet series, as well as which seat it is that you wish to use, and see which seat fits for your toilet.

Q. "I'm sold. I'd like to just try one and maybe I'd keep it. Can I try it and if I don't like it just have you pick it up?"
A. We do not sell used toilet seats (so you know that when you purchase one from us it is new and not a returned bidet). Therefore, once you have purchased a toilet seat, it is yours. If any HomeTech or Toto bidet seat proves to be defective within 30 days we will ship you another one (once we have received the original one). We have never seen a defective Toto or HomeTech seat, as they are both of excellent quality. After 30 days, warranties are handled by the respective manufacturers.

Q. "How long will it take for you to ship these seats?"
A. Most models are in stock but some rare colors might take as long as 1-3 weeks.
