Is there a special part to move a cast iron tub drain a few inches such as the 'off -set closet flange' for a toilet? Am still working on the specs for remodeling a teenie bath in a pre-WWll bldg. We plan to rip out thick tile & lath/plaster walls in the tub alcove and replace with 1/2" cement board & 1/4"marble tiles to install new narrow acrylic tub. We're hoping to gain a little space but know the tub drain is cast iron in cement floor... if we move the toilet 2" as per Speedball1's advice and can kick the tub over a little we can at least have enough space for a 24" wide sink vanity and make the bath really up to date... help!

Perhaps, if you have the room, you can swing the trap and make up the difference by offsetting the raiser with 45 degree ells but I wouldn't bet on it. The sure way to do it would be to break up the cement, remove the trap and use fittings to move the drain line and then reinstall the trap and raiser. Good luck, Tom

Thank you Speedball! Again - you are a wealth of info... from Madam Goodwrench
