						SupporterAs you probably know, there are several different grades of stainless steel. And then there is the crap made in China being passed off as stainless!
316 is not the highest grade but the best compromise. Yes, hospital grade SHOULD be the best, but as 4Bee says, you probably wont find it at Bunnings.
Without being picky: unless you are pumping water into your pool from the ocean, the water in the pool is not salt. The salt added to a "salt water pool" is used by the chlorinator to produce chlorine to sanitise the water and does not make the water "salt".

The shower chair was not bought from Bunnings but from a chemist shop & it was not cheap . I would drive 20 min out of my way than buy something from Bunnings. As for the fittings out side near the pool when they were bought I specified they had to be Stainless Steel , within 6 months the screws start rusting .
Yes I know about all the grades of Stainless , My brother & I owned a steel & alum fabrication business for over 35 years. As for salt water pools they will make anything made from steel near them corrode . Our house was 3 years old when we put the pool in , within 2years of the pool going in we had to replace steel gutters on the house , which was put down to pool water. The water may not be as salty as the sea but you can taste the salt in it.

How does the pool water get into or on to the gutters? If the gutters are corroding so quickly the pollution is coming from some place else.
The chlorine in the pool does evaporate, which is why salt needs to be added from time to time, but there should not be enough salt left after the chlorinator to taste ANY in the water.
So what you are saying that every time I get the pool water tested & they tell me the salt level is correct or needs a bag of salt they are wrong & the salt level is high. The chlorinator also has a gauge on it that tells me how much chlorine it is making & there is a variable adjuster to adjust the chlorine level , if the salt is high the gauge goes into the red so I can either decrease the chlorinator or backwash add more water to reduce the salt. My last house had a non salt water pool & was in the same area as we now live , we never had corrosion problems like we do here.

						SupporterThere are several other factors that need to be considered, the most neglected is probably the TDS (Total Dissolved Solids). Is that being tested?
The salt level in such a pool should be around 3,000 ppm, ocean water is around 30,000 ppm. While individuals taste perception varies, at that low level you should not be tasting salt.
https://www.portagecounty-oh.gov/sit..._generator.pdfVirtually everything that is added to the pool contributes to an increase in the TDS value including chlorine, shock, algaecides, clarifiers, pH remediation products, etc. Even bather-introduced contaminants such as hair care products, body lotions, deodorants, sweat, urine, etc. can significantly add to TDS levels
