I've got this idea to pave my tub with melted marbles. The tub has some kind of finish on it where there is a design of ovals that is less slick than the rest of the porcelain, but they have turned grey, and nothing, but nothing cleans them, so I'm just going to put a mosaic in over it. The melted marbles come in different sizes and they are flat on one side, so they should stick pretty well with the right adhesive. They are comfortable to stand on, and great to sit on or slide over--great backrub! I had a rich pal once who had this done with fancy little river pebbles in a very elaborate tub/shower enclosure. It was gorgeous, but I'm going with the marbles for the color and finish variety. But what should I use to stick them to the porcelain that can handle being stood on?Any ideas? And is there any way to pull that marred drain thingy out of there and put in a new shiny one? I'll be darned if I can figure out how it would come out. Of course if there is any practical reason not to do this marble nonsense (aside from the damage it will do to my resale value--ha!) do let me know. Thanks!

 

ae1, Welcome to the DIY Forums.
I'm sure there is a product that will adhere the marbles. Not sure if it will last after being saturated with water though. I would also hate to be the one cleaning this tub. Soap and shampoo residue is hard enough to control on smooth surfaces. Good luck.

 

Yeah, regular maintenance will be important. At my pal's house, the pebble was dark grey and black and it was just stunning when they put it in, but after a while, the buildup was too evident. I'm gonna use light colors and regular soft brushing. I think I'll have to etch the porcelain first, but I might get better feedback on the adhesive question from some tile guys. Thanks, Dragon.

 

You are correct. The tile guys know what works and what doesn't. Good luck.

 

Sounds like something which will be very slippery to stand on. Not good.
