It was easy enough to replace, although I am pretty handing with most repairs and I did google videos on how the properly replace this balancing unit and the valve.The shower is like a brand new shower, working out well. No leaking issues, probably because I followed the videos precisely. ### ⭐⭐⭐⭐⭐ Great value, easy to install, do it yourself *by L***R on December 19, 2023* Fit my Kohler faucet like a dream, worked perfectly. Easy to install (do a quick Google/YouTube search) and probably saved me $$$ in plumber fees. ### ⭐⭐⭐ O ring size *by L***0 on April 22, 2024* The O’Rings that fit on the outer section of the valve are cut too large. They will not fit and overlap the cutout slots. The inner O’Rings work fine. Waited too long to return now have to find O’Rings that fit. --- ## 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.hr/products/509031893-gp500520-pressure-balancing-unit-cartridge-shower-replacement-the-model-gp500520](https://www.desertcart.hr/products/509031893-gp500520-pressure-balancing-unit-cartridge-shower-replacement-the-model-gp500520) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-06*
