Wow that's excessive for a shower, and just one reason as to why I prefer to do these type of jobs myself.

Hob.

 

Yeah, I keep forgetting as that is not what I associate primarily with the word hob.

I get that this is not your council, but they are all working with the same legislation.  Like I said I would call them.

I would do this, but with a tiled shower that has been replaced, you wouldn't necessarily know if it was the original or a new one, or what work had been done to it, if it was a like for like replacement. eg The LIM may show it has a tiled shower, and it still has a tiled shower.

 

IMO it depends what the real estate market is like. During the last few years many weren't even getting building inspections done because there was so much FOMO in the market and sellers often had multiple offers they could choose from, so would often go for one that isn't conditional upon a building report etc. Or the buyer would get it inspected before they make an offer. So if someone was being picky with that sort of thing, they seller wouldn't sell it to them. IMO if you are buying an older house, you have to expect that you are going to need to spend quite a bit on it in the coming years.

 

Totally, and equally you may get away with it like lots of unconsented work.  But if somebody realises, it could well effect your value. 

There is also the overriding fact that the replacement is occurring because the last renovation (that was unconsented) failed prematurely.  Tiled showers are an area where failure rates are high, and the very reason you should get it consented, to see it adheres to requirements and doesn't leak!

Currently we have something similar to this:

We have something like this https://atlantis.co.nz/trade/shower-base-system/ 

Well, I thought I'd call another option from No-Cowboys sight unseen he said he had done a couple of these already and quoted 12K including tiles. Subject to change upon actual inspection.

His description of what he was basically doing matched that of the $8K quote.

We've built a few with a waterproof membrane (tanked) floor and it is expensive. As I understand it, a shower unit built on a manufactured one piece base is much less expensive.

Thankfully, we now have a confirmed date for the start of the shower repair. It's 10 days away, will take around a week, and then the other people can come in. With any luck, we can be all said and done with the whole saga once and for all before Xmas. 

It's put a serious dent into our mental state with working full time and all this as well. I wouldn't wish it on anyone.  The flip side is that whilst this is all eye wateringly expensive, I feel as confident as I can be, that we MANY long standing issues are all being addressed as a result of this, and that the house will be a fantastic place to live in which is good for our mental state. 

Does anyone know this waterproofing product? 

mapelastic aquadefense

It's what they are using to waterproof the shower, I hadn't heard of it before, and online presence at a search seems non-existent in NZ. 

Doesn't really matter I guess, it's what they are using, we don't get a say, but was wondering if it was a common/good product? Not sure if Waterproofing products need to be certified in NZ or if this is.

Google threw up multiple hits such as:

https://tiletrends.co.nz/mapelastic-aquadefense-15kg-each.html

They have the compliance statements/etc published at https://www.mapei.com/nz/en/products-and-solutions/products/detail/mapelastic-aquadefense so it looks like it's approved/etc. The BRANZ document has photos of the proper/certified installation method/etc.

Things seem to be progressing. Whilst it's been much more expensive than we anticipated (but still what was quoted), so far, the trades people have turned up when they have said they would, done what they said they would, and to our inexperienced eye, are doing a high quality job. 

They tell us we can use the ensuite from middle of next week, and that should mean the painting and plastering being done downstairs can begin on time or slightly ahead of schedule. 

So just when we think things are going well, the second layer of waterproofing went on. 

They weren't even going to do an overnight waterproof test, which was part of the quote and one of the big selling points that gave us confidence in the solution, so they decided they would do it, but then it's all bubbled massively. 

Waterproofing guy says he's coming back in the morning to 'fix' it, he thinks the screeding wasn't completely dry. 

I say, hang on a minute, screeding? You don't need to do screeding if you use a Marmox base. He says he was told to do screeding so they didn't have to use a base!

I am pretty sure it was this firm who said for upstairs bathrooms a base is much preferred. 

So frustrated to say the least! There are a queue of trades people to follow these guys all set for a specific date!
