how high is your shed? The video is just using metal studs as opposed to timber. Your shed is so small, so dont over think it as once the tin is screwed into place, it will tie everything/stiffen the entire structure. Keep in mind, the kit sheds don't have any studs and are screwed/riveted together with a track top and bottom, Many different ways to achieve the same end result. You can essentially build all 4 stud walls on the ground, stand them up and screw them together...no...

....and not just the tiles. You will need to reline the shower walls with new cement sheeting. Step 1 is to rip the entire shower recess out so all you see is the framing and go from there. Plenty of options to consider for the base including a poly marble base that if installed right (mortar base with zero air bubbles under the base) will out see the life of the house. Is it on a timber floor?? as your likely to need work on this before anything else. Get a copy of the standards...

I'm not a welder either but bought one and looked at a few Utube videos and taught myself to weld...rough at first but now an OK "back yard" welder that comes in handy for the odd small job. If your keen, go do a TAFE course, their cheap and could be a skill you may use around the house in the future. A little secondhand Arc welder is cheap <$80 will do most little odd jobs. The kwiktech option looks OK but more steel than necessary (ie: more cost) than if it was welded based on the web...

...a couple of photo's would enlist a better reply :)

Yes, since COVID, a lot of stuff as doubled in price!!! Went to get a drum of 2.5mm yesterday and said bugger me, this was ~$100 prior to COVID and now it ~$190. Even conduit has increased by 50%. Would like to know who is screwing who over...is it the retailers, manufactures or all of the above. Not even close to an expert on the standards...so are you running it to a sub board in the shed? If so, does this make any difference on the requirements if you should use SDI or just building...

+1 to JB1. only way to fix it to todays waterproofing standards in to rip it out and start again. There is no way to effectively waterproof the entire showerbase/shower walls from that position.

After building a few, (take plenty of photo's and mark up a copy of the layout drawing) I do the following: Noggins - important so the attachments don't constantly come loose and fall out/break off the wall with use/pressure like towel rails 1. Noggin's between studs (90x45 or 150x45) for towel rails, toilet roll holders, clothes dryer, possible coat/towel hooks, Broom cupboard hooks or into the underside rail holding a shelf up 2. Noggins between the ceiling joists (150x45) in all...
