There is a point very sensitive where the water gets straight too hot or lukewarm when turned back so very difficult to regulate if your desired temperature is around that spot . **Q: is it easy to replace a mixer at a later date. I hope this is one of those that once installed the top bit (the mixer) can easy be swapped it required** A: Yes mixer can easily be replaced **Q: i have grohe 19382000 eurosmart cosmopolitan single-lever bath mixer trim set. will this smart box compatible as concealed part?** A: Yes. My pump is behind tiles. Only the switch gear - lever for overhead and separate shower head is visible. This bread and butter for a plumber **Q: Will this work with a salamander water pump. Plumber has stated it must be a low pressure unit due to the pump being used** A: I have this unit working with a 3bar pump no problems I believe the max bar is even higher than this ## Frequently Bought Together - GROHE Rapido Smartbox - shower systems - universal concealed installation unit - DN 15-35600000 - Grohe 28672000 Relexa Shower Wall Union, 0.5-Inch Threaded Connection, Starlight Chrome - GROHE 35601000 Rapido Smartbox Universal Rough-In Box, Starlight Chrome --- ## 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.be/products/55478026-grohe-universal-rough-in-box-3-outlets-1-2-2](https://www.desertcart.be/products/55478026-grohe-universal-rough-in-box-3-outlets-1-2-2) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-07*
