This project was a second remodel to a basement bathroom. The previous 2 piece tub had leaked and I'd been dreaming of doing a concrete bathtub. This tub was thrown out of a carvable vertical concrete mix and then stained with water base stains and sealed. The tub is now 4 years old and looks EXACTLY the same. The tub is 30" deep and the tub is filled through the lion's mouth, our kids LOVE it!
