Bathroom Renovation

[MasterPlumbersKeymaster]

I have two questions regarding a bathroom renovation.
1. For the shower recess do you need to use a copper tray or is a membrane a sufficient barrier. Some quotes we’ve received do not mention the use of a tray.

2. One of the quotes we received for our bathroom stated that a water temperature regulator was required, by law. However one of the one of contractors said he did not know of any requirement. (by the way, we are in New South Wales)

Thankyou for any help.

Even if a pressure balanced valve were not required in NSW, it would still be beneficial for you to install one.

Answer: I happen to like a lead “tray” pan but I have used copper also.

As far as membrane “plastic” I honestly do not care for it

If using lead I use 4 PSF and for copper I use 14 Oz per ft

Answer. A pressure balancing valve WILL NOT protect you in case of a hot water failure as they only work on pressure differential and they do not sense temperature fluctuations regardless what others think.

For better protection you should have both a pressure balance AND A temperature/temperature valve installed.

It cost slightly more but affords the best type of protection against accidental scalding

You can use either a membrane or a copper tray. And YES by law you do need to install a tempering valve on the new bathroom. Might consider placing it back at the HWS and do the whole house
