I want to replace the tray shower and I'm looking at possible options.




I figured I can do the ripping out myself and then it's just figuring out the best legal way to proceed from there.




Currently i'm thinking of a layered approach to the walls as I don't want to do just another box shower:


1) Aqualine Gib over framing


2) Waterproof polyurethane membrane 


3) wet wall lining ie showerlining 


Tray on the bottom with the wet wall lining overhanging.


Does that seem plausible? Do I need to get a builder to do this for me or can I do most of it myself?

I recently had a new shower put in (walls tray door). some walls needed to be aqualined again. took the shower installer the best part of 6 hours to install, including a trip to grab the gib (40 mins).


After that I swore I;d never try to do it myself. If the pro takes the best part of the day normal DIY would take much longer

Your shower isn't going to be a box shower, but you are going to use a shower lining and tray? 


I'm no plumber, but do you need a membrane if using a shower liner? I would have thought using GIB Aqua would be enough. 


I.e. Install GIB on walls, place shower tray on floor and mark position on GIB, then cut the GIB 10mm above the marked line of the tray. Then place the tray in the rebate you have now cut out, checking that the front face of the trays upstand doesn't protrude past the GIB. Then when installing the wall liner (hold it in place with tape first to mark the positions of plumbing fixtures etc before fixing permanently), run a generous bead of silicon along the top front edge of the trays upstand.  I think that is the most common way of doing things. I think you only need a membrane if you are building a walk in shower using tiles etc. 

Oh and obviously, the shower liner would overhang the tray upstand.

^ What he said. Needs to be done properly or it will leak.

Bathrooms and in particular showers should really be left to the professionals, the money saved in DIY can be eclipsed if things go wrong and it doesn't take much for a little mistake to become a huge fix up problem.

We went with an acrylic shower at our place, replacing a tile shower that had failed and leaked badly. These are some instructions that will give you an idea of what is involved, if you decide to take that route:


There will also be some plumbing work required, with the fittings and waste etc. 


As above, it is a job that even took the professionals quite a while, and is not something that I personally would try to DIY, given the potential to ruin relatively expensive shower components during the installation. But, I am by no means a DIY pro.

If you doing a kitset shower with an acrylic liner then aqualine behind the shower is fine. You don't need a separate liner. I have installed 3 and they are not to bad to do, but not suitable for a beginner. The walls have to be square and true vertical and the floor has to be level. Additional complications are the waste and mixer being in the wrong place, but you can get a plumber to sort out these in advance.

Above all else you need to comply with the building code. E3 is the exact clause that you want to investigate. Refer to pages 16 and beyond in particular.


You should also refer to Schedule 1 exemptions for building consent. Any wet area shower membrane work requires consent and you should refer to the specific manufacturer information as to the warranty if you apply the membrane yourself as a non certified applicator.
