The tub will not crack a quality ceramic tile. Remember that back
in the day, they put these on lino.
If you do decide to put in a claw-foot- take into consideration the plumbing drain & fixtures that will be required. ie: All chrome-or brass.And that these will need to be re-located *before* you install the tile.
*Also (this is very important!).. leave a wall out, so you can simply carry the tub in. "They dont go thru doorways/make turns easily.

Have fun & I hope you dont have any bad back issues.
