Had no issues at all. **Q: Hi there where do you buy the remote from to re program the sensor position please ?** A: The remote is about £300 so unless you’re a professional bathroom fitter you won’t be buying that. You can’t change any of the settings without the remote. **Q: Is there a brass version of this, also mains powered?** A: I believe there is. However....since having the tap for 15 months. I have the battery operated one, had two battery replacements...a new tap replaced by Grohe in July 2022. Not surprised, battery dead once again. **Q: Confirm mains-powered is an UK Plug?** A: I’ve had mine for about 15 months and the battery has already gone flat. It’s in an upstairs bathroom just shared by my husband and I. ## Frequently Bought Together - GROHE 36451000 BAU Cosmopolitan E, mit Mischung und variabel einstellbarem Temperaturbegrenzer, Chrome - GROHE 35601000 Rapido Smartbox Universal Rough-In Box, Starlight Chrome - GROHE 27412BE0 Relexa 6 5/8″ Tubular Shower Arm, Polished Nickel --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/116276712-bau-cosmopolitan-e-infrared-sensor-touchless-basin-mixer-tap-mixing](https://www.desertcart.no/products/116276712-bau-cosmopolitan-e-infrared-sensor-touchless-basin-mixer-tap-mixing) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-11-14*
