Planning a bathroom reno or need to replace the guts of your shower? This upgraded 3/4-inch rough-in valve is the heart of the system. It's a direct replacement for the Hansgrohe part number 01850181 (also HG01850181) and is compatible with a bunch of their valve cartridges like the 04230000, 04233000, and 15763001. Double-check your existing cartridge model before you buy! The valve body itself is made from a strong, durable PVC composite material, not cheap metal that can corrode. The design includes integrated service stops, which are little shut-off valves right on the unit—a huge help for future maintenance because you can turn off the water to the shower without shutting down the whole house. The PVC shell and rubber seals also help cut down on vibration and water hammer noise inside your walls. It's built to mount securely onto your wall studs. A solid, reliable foundation for your shower that works with pressure balance or thermostatic trim kits.
