concrete over bathtub?
 
Hello, is it possible to poor concrete over an existing bathtub? Looking to make bathroom more modern and love the look of concrete. Plus, the bathtub has a leak somewhere, I'm thinking the concrete will help to make it water tight. Is this a good idea? New at this kind of thing. THANKS!

Like this one? I think concrete can look very modern and artsy. If done well, you shouldn't be able to tell it's just plain concrete. I also like stained concrete flooring. It can be very nice.

So you tihnk its ok to do a thin coat of concrete over the existing bathtub? I don't want to remove it and start over. And will it help reduce leaks?

I've never heard of using a thin layer of concrete on top of an existing bathtub, but that doesn't mean it hasn't been done. You didn't say what the existing tub is made of (enameled cast iron, steel, fiberglas, etc.?), and that could affect the success of such a venture. Also, be aware that concrete will usually crack when exposed to varying temperature extremes, and some of those cracks could eventually leak, putting you back at square one. Keep in mind, too, that concrete will be colder to the touch than your existing tub, so be prepared for your hot bath water cooling down faster during use than it does now.

Interesting concept. It's going to be fairly expensive. In addition, concrete is a porous material, so it will need to be sealed in order to prevent staining from the constant moisture build-up. It's also a tough material, so I am not sure it's going to feel very good on your skin. Unless you intend to use the tub for primarily decorative purposes, I am not sure this is the best material for your purpose.

If it's fiberglass, the weight of the concrete could do more damage than good. I'd get rid of the tub completely if concrete is what you want. It needs to be done CORRECTLY or it will be rough, will crack, etc...

I see you are new and I want to be polite and all but, give your head a shake and go on to plan "B".

If you look closely at your photo you will see that the tub surround was applied peices and what about the leak in your tub?
