Frequently Asked Questions

Q: Can I install my Oben hydro-massage shower system using 1/2”
supply lines?

A: Yes, it is not necessary to have a 3/4” supply line provided you install a 3/4 ” thermostatic control valve.
A 1/2” supply line plumbed to a 3/4” thermostatic valve with adequate pressure effectively increases water flow. However, 3/4” supply lines are preferred wherever possible, especially for new installations,
to guarantee optimum performance.

Q: Why a Thermostatic Control Valve?

A: Oben recommends using a 3/4” thermostatic control valve, which delivers exceptional flow rates. Thermostatic temperature control in a Custom Shower is much more than a performance consideration; it minimizes the risk of thermal shock and is therefore a safety consideration for your peace of mind.

Q: What are Volume Controls?

A: A separate volume flow control valve is used to turn water on and off for each individual spray function (Overhead, Hand Shower or Body-sprays). Volume controls provide the bather with a choice of individual or dual-function showering options. Starting from the “off” position, you can steadily increase water flow through to the “full on” position or anywhere in between. Oben recommends using 3/4” volume controls throughout the system for maximum showering performance and satisfaction.

Q: How many shower functions can I operate at once?

A: Oben recommends you operate a maximum of two shower functions at any one time or there will be a reduction in performance. This can mean any two (dual-function) combinations of Overhead, Hand Shower or Body-sprays, or a single spray function if preferred.

Q: What is the minimum water pressure I require?

A: Optimum recommended water pressure for dual-function showering is a dynamic pressure of 45 PSI or higher. (Minimum 36 PSI).

Q: What size floor drain do I require?

A: A standard 2” floor drain provides sufficient drainage for one 3/4” thermostatic control valve.
