How to build a shower base?

[Sedg]

Hello again

i posted a question regarding framing the other week and recieved some great help, thank you. now i am measuring and locating where the new wall will go and i see the recess in the concrete overlaps the location for the new frame about 40mm. also the recess for the shower is very rough and not square, it is just over 1000 long and wide with rough edges and varies in depth 70 - 90 mm deep.

obviously i need to reshape and fill this "whole" can you suggest how ? should i build a square box and center is and fill the outside with grout or concrete or something else? and what about the base or floor area, surley that will require rendering with something

here are some pictures, i hope you can help oh ftu the copper pipes will go and i will re blumb with PEX. thank you

Hi Jacob

im checking application videos on line and there seems to be conflict 

do i put the tape on first then mix compound base coat and apply it ? or do i fill the gap first, then tape than do a final coat with the basecoat ?

a lot of these vidoes are from th US and of course they use different compounds

let me know what you suggest

thanks again

Hello @Sedg 

Yes, the correct sequence for James Hardie cladding finishing is to apply a base coat, then embed the tape, and finally apply another layer of base coat over the embedded tape.

If you need further assistance, please let us know.

Thanks Again

it seems non of the Bunning outlets on the gold coast carries James Hardies base coat any more, the guys in the store recommended Gyprock wet area base coat. will this suffice >

thanks

Hi @Sedg,

Yes, the Gyprock CSR Wet Area Base Coat is also suitable.

Hi again

thanks for your help, my next question regarding the shower base, as you see it requires screeding and water proof

which is first ?

thanks again

i have a price from a local tiler who can screed and tile for 3300$

Hi @Sedg,

According to the National Construction Code Part 10.2 Wet area waterproofing, specifically Part 10.2.21 Membrane installation for screed -

"Where a screed is used in conjunction with a waterproof membrane, the waterproof membrane can be installed either above or below the tile bed or screed."

Essentially, your waterproofing membrane can be applied either above or below the screed, or both if you want that extra peace of mind.

Let me know if you have any further questions.

Hi Jacob

as you have been a great help to me I thought i would brief you on my progress

attached are picture before , during and now

I did bring in a professional tiler to do the water proofing and tiles, everything else i did alone 

note we waterproofed below and about the screeding. more tiling to go, the laundry and toilet have also been prepared for sealing and tiling

i will use shark bite plumping for the shower, ive install new breech and tap assemblies.

thanks again for your help, i will show you the finished article soon

regards
