Cast Iron Tub Removal


I've got to remove a cast iron tub tomorrow so that I can start building another tile shower. My plumber told me to just beat it apart with a sledge hammer but that seems to be a lot of work? Has anyone found any tricks in getting these big heavy mothers out?

Re: Cast Iron Tub Removal


If it's on a 2nd floor, be careful. All the beating can upset the ceiling below.

Otherwise, yes. A sledge can handle a cast iron tub demolition.

Re: Cast Iron Tub Removal


This is about the only operation on an inside remodel where I feel it's acceptable to use a sledge. As Angus said, be mindful of the floor. Also remember to take any wall hangings off the other side of the wall.

Re: Cast Iron Tub Removal


I just did one about 3 weeks ago and yeah it was a bit of work (i broke it up with sledge )
I started making good progress when i hit it with the beveled edge of the hammer head but its loud and alot of shock waves , If you break it up ask h/o to remove pics or mirrors nearby

You could put rubber pads under the feet to reduce harmful vibration.

Re: Cast Iron Tub Removal


I bought a guy a new floor when I was 19 cause I thought I was a man.

I start on the front and break the apron off right down the middle where the shower door would sit. Then break whats left in half. Thirds are pretty doable. Somebody on here once said to cover with a drop cloth first. Seems like a good idea as the porcelain comes of like glass shards.

Re: Cast Iron Tub Removal


Use hearing protection or you'll be screaming at people for the rest of the day. Also don't swing so that you are hitting pieces back toward yourself, my shin is still sore from the two hunks of marble from the tub I busted up over two weeks ago.

A sledge is perfectly acceptable for busting up pink cultured marble as well.

When I can't smash it, I cut it up. Takes about the same amount of time, less energy, different kind of messy.

Diamond blade on a grinder thru porcelain and then a metal cutoff.

In half is okay if you have help.

I used to beat them out, then I cut them out, and now I just friggin pull them out. They come out in about 30 minutes. Pull the drain. Lift it from the back, clear the plumbing stand it up right. Grab an applaiance dolly, strap it in and walk it down with two guys on the bottom.

No need to beat it to death and get all hot and bothered. No need to throw friggin' hot metal everywhere and breathe in all that crap.

I have one tomorrow. We are pulling the tub, the surround walls and replacing with a shower. We will have it demo'ed, plumbers in to do their thing, then set the pan by lunch. I should be able to have the walls rocked and maybe one coat of AD by the end of the day tomorrow.

As long as he is insured and has his own WC.

Re: Cast Iron Tub Removal


I have to agree with pulling the tub out. Breaking a cast tub with a sledge makes a heck of a mess, it's loud, and all the beating is pretty rough on ceilings under the tub and on any walls around the tub.

Re: Cast Iron Tub Removal


Its on a second floor so I am worried about the ceiling on the main floor. Below is the dining room. My only worries are the existing tile floor is staying. Prying the tub up off the floor is where I do not want to mess the tile up.

You don't need to pry the tub up at the tile. You just need to cut away any caulk and remove any grout between the tub and the tile.

Remove the surround walls and lift from the back. You may have to play with it a bit to get it loose but it will eventually break free.

Okay, good point. My metal guy doesn't even have insurance for his truck (as required by law around here) much less contractor's liability insurance. Plus, presentation isn't an issue. I'm working exclusively on vacant properties that I own. So it's not an issue that the guy is missing both fingers and teeth - until the neighbor's call the cops on him and I have to explain to the local PD that he has my permission to be there! Okay, sorry, it seemed like a good suggestion at the time!

But think about this. If you own the property, then it is your HO policy that has to cover if he gets injured while pulling one of your tubs. He could end up owning one of your houses and then some. Just be careful.
