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. "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. Unfortunately we do not sell used or returned toilet seats (so you know that when you purchase one from us it is new and not a returned bidet) and therefore, once you purchased it, it is yours. If any HomeTech or Toto bidet seat prove 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 the warranties are handled by the respective manufacturers.

Q. "How long will it take for these seats to ship?"
A. Most manufacturers ship with 24 to 72 hours from receipt of the order. We will contact you right away if there is a delay in shipping beyond this lead time.

Q. "What is the Wonderwave® spray?"
A. The Wonderwave® spray describes all of the amazing features packed into the washlet's wand. These features include the gentle aerated, warm water, dual action spray and the oscillation and pulsating features as well as the adjustable warm air drying settings.

Q. "What is the eWater+™ function?"
A. This function uses water to mist the toilet bowl after each use. This makes a clean toilet bowl easier to maintain and reduces the need of using harsh cleaning chemicals frequently.
