Cast iron tub remove\install


Just began a project in the bathroom.
I have the vanity\top, toilet, tub surround all taken out but am a little leary tackling this cast iron tub, it needs replacing (chips and cracks etc...)
What should I expect after busting up the old tub? How is the tub supported? It sits above floor.
Nothing rotted out it all seems to be in good shape, I'm just wondering if it sits in a mortor bed or is it supported by a wood subframe.

Any pics or advice would be greatly appreciated.

Good chance that thing is held in by shear weight itself, guessing here the thing comes in around 300 lbs +/-. Don't break it out...huge mess, glass shards will be everywhere. Find 4 people you really don't like, entice with beer and have them carry it out of the house, kind of like the donkey with a carrot.

Have you considered having the tub refinished?

I believe the tub has been refinished, possibly by the previous homeowner.
It seems spotty finish wise, nice in some places, gritty in others.

It also looks like the previous homeowner tried to pull out the drain by trying to pry something under the drain. It is chipped pretty bad and is rusting.

I had planned on drilling three lines of holes 1\3 out the tub, and popping them out the crawl space, lots of room down there.

The wife and kids are gone till Monday so me and a buddy are going to try to bang the tub, floor and toilet out Fri eve\Sat morn.

VERY small bathroom, 14' deep and 5' wide.
All I have left is the tub and toilet, I'm snapping pictures this eve and will post pre project pics tomorrow afternoon and post tear down Sat afternoon.

5 day bathroom remodel.
Bushmills and Budwieser will be our only companions.

One way to remove an old cast iron tub:
Cover with an old blanket, wear safety glasses and heavy gloves, and break it up into manageable pieces with a sledge hammer.
Good Luck!
Mike

Mike Swearingtons method will work. If you don't want to do that you will need two strong guys. Just disconnect the drain, remove the tile on the wall or at least the first five inches or so of it. You can then just lift and slide it out. Remember, this thing is heavy.

I already have the new tub in the garage so I'm well aware how heavy these are.
What do you think of the idea of drilling holes and "sectioning" the tub into 1\3'ds and break it up that way?

I'll post pics of the repairs pre and post later this evening as well.

Toilet and floor are gone as well, the water damage is minimal where the floor in the pics wasn't removed yet.
Tore it all out and laying underlayment, installing tub etc.. pics up later this eve.

Oh, by the way the tub came out in one piece!!! My friend and I turned it up on end and used a hand truck (no stairs!!). The hardest part was dragging that sumbeeotch up my ramps into my F-150 sittin on 33"s.
