Check out this post - I hope this link works. Someone asking about a teak bench vs marble topped one...

If you really need a bench can you have one built in using your shower tile? It seems that would allow more room inI the shower. Good luck!

Another possibility would be a folding teak seat:

These are available from several different makers.

I don't think teak would be an issue at all. Redwood or cedar, possibly. But not teak.

Thank you everyone. I appreciate you taking the time to give some feedback.

I prefer the freestanding as opposed to a wall mount or built in. I like the flexibility of a free standing. I will give the teak a try.

I have had a teak seat on top of a crema marfil bench for years in the bathroom. No staining issues at all.

I sand and waterlox the bench once a year. It looks new again :)

We have a freestanding teak shower bench on a very light beige porcelain tile floor and it's been a non-issue. Bathroom is now 2 years old.

Did you ever have a staining issue? I’m doing the same. First day, saw staining...

We just added a teak bench and it stained the bell out of our grout. I guess the next question is whether it was actually teak.

We have a teak bench in cultured marble shower floor. I have bleached it and used 0000 grit steel wool. It’s lightened a bit but not out. Still searching for something to remove the residual stain as we can see streaks straight from where the legs sit and know it is not rust or iron from the water

I have the fold down bench and it has stained my fiberglass/plastic base. Haven't tried cleaning it yet, but it did stain the floor pan.
