If your really concerned then engage an independent inspector at the waterproofing stage to ensure its done to min std in accordance with building code and relevant stds.
I am aware a lot of builders get picked up for unenclosed showers (walk ins) - these have to be waterproofed on the floor to 1.5 meteres.
How do you "waterproof" a bathroom? Is it something you can do yourself after handover? Or is it a professional-only job?
you cant do after handover - has to go under tiles - on top of cement sheeting etc - its not a very difficult job - youtube has videos on how its done - you can buy the membrane and waterproofing paint from bunnings etc. Keep in mind that any wet area waterproofed according to the relevant building std in considered acceptable. Applying the waterproofing membrane to the entire bathroom walls and floors would be overkill - although I would prefer the entire floor to be waterproofed as this is where water can pool - it cant pool on a wall. So if you were willing to pay extra- get the floor of the bathroom upgraded to be waterproofed - don't worry about the walls - the joins will be waterproofed around bath hob and around the shower.
Thanks Ubet7 I am having trouble reconciling how it could cost $4.7k to paint on the waterproof membrane that retails for $80 for 4 litres to the bathrooms and toilets even allowing the time to lay 2 coats. Agree that applying to the floor is probably a good approach.

that quote doesnt appear right - especially if your talking about one bathroom - that sort of pricing would get you a structural improvement to the house - ask them to recheck now that you know more about what it involves.[/quote]
Hi all
We have been in our CH for about 18months now and had a cracked floor tile in shower ( floor ) when i pulled the tile up yesterday some of the base come up with it exposing a grey sand material anyone know what this is?
Also what does the waterproofing look like ?
Looking at the installation certificate it says shower base only and small niche
Im waiting for CH to call me back about this as the wetseal has a 7 year guarantee
Will let you know how I go[/quote]
My understanding is that Carlisle use a shower base and then lay tiles on top so the actual shower base is the waterproofing agent in this instance. The material you are referring to is the laying compound. The fault will lie in either the tile or the way it was layed - definitely should be fixed by Carlisle as its a fault and should be no issue with waterproofing as the waterproffing is in the shower base.
