As mentioned in @Spinal 's recent thread on obtaining boiler parts, doing anything DIY here can be fraught with frustrations, red tape, lack of parts and so on - and the cost of getting someone to do it can be astronomical or totally over the top.
So, put your DIY stories down here with photos, links to suppliers and regulations and helpful hints here:
Shower Repairs:
From Spinal’s thread:
Showers
Door runner replacement/repairs
The nylon runners on the round glass doors of our shower were cracked and broken so the doors would not slide smoothly.
I got no response from the manufacturer or distributor and the only original part I could find was a one-off on eBay for ÂŁ80. (I needed eight).
So I bought some brass M6 bolts and nylon wheels (with an integrated ball-bearing race) from Ali-Express. I cut off the bolt heads and filed down the threads to make a compression fit with the center hole in the bearing and screwed this into the existing off-set plastic parts.
Works a treat and was less than CHF10 in total.
Shower Seals
It’s sometimes difficult to get the right door seals here with the right profile and dimensions here. Use the wrong one and you’ll get water everywhere.
I’ve used https://showersealuk.com/ in the UK and they’ve been great.
Not specifically for steam showers but for other parts too, https://www.steamshowerspares.com/ has been excellent.
A little bit of a “given”, but i order a lot from:
https://www.buyspares.de/
(and get them shipped to a German postal box)
Another one, that apparently has parts. Haven’t ordered from them yet - but they seem to have a selection of parts:
Well I grew up in my Grand Uncle’s house, a master blacksmith, so I had a good teacher! My earliest memory is fixing a leak in a framer’s bucket with a bit of solder. And in those days you stoked up the fire, heated the soldering iron and worked fast before it cooled.
The most important thing for me - buy proper quality tools, not the crap you get in DIY shops. I go to the local hardware shop where all the tradesmen buy their stuff - better quality, better advice and you get to network with the local tradesmen early on Monday mornings, when they are in stocking up for the week ahead.
