If it is a slab foundation, there should not be any room under the house. You and your contractor are talking two different languages and make no sense. If any other tub or shower can be installed, then what the skirting looks like should not matter.

Fred, thanks for your comment and let me see if I can be more clear-I agree I am not sure exactly what the contractor is saying. I have attached pictures to help- we are putting the tub where a built-in tub was. The plumbing is already coming out of the slab and was going to have to be moved approx 2.5 feet to accommodate a center drain vs end drain. The plumber says we cannot go deep enough necessary since this tub has integrated waste/overflow? Basically says we cannot install a freestanding tub unless it has a pedestal or clawfoot or we build up the floor where the tub is going to go. Does this make more sense? He said if we were on pier and beam or it was going in an upstairs bathroom it would be no problem.

What brand and model is the tub? I will try to look it up.

You will probably have to copy and past these references into Google search to find some of these references, because they are only a partial url. The first one describes a typical installation with standard slip fittings like under your sink. The plumber needs to get to these after the tub is in place. That is the problem.

The first picture is just to show there is plenty of height in the plumbing to move the pipe anywhere necessary.
The second link is showing some fancy connection method in Australia that you set the tub over a glued trap assembly. Don't know if it exists here.

This link is how they do the drain connection on a shower over concrete.

The problem is the integral overflow. The second picture is a bathroom sink with an overflow. The overflow water comes down in the middle of the tailpiece, and I don't know of a shower fitting that will work like that. That doesn't mean it doesn't exist.

One suggestion I found was to do a glued trap like a shower and attach the tailpiece to the tub with a threaded pvc adapter on the bottom while on sawhorses. Then cut the pipe in the floor to the correct height and glue it on as you set the tub over it. I don't know if this meets local codes, and it will be a bit tricky to do, but it has been reported to work. Just make sure you set the tub down in the exact right spot the first time and seated well because it is quite permanent.
I wrote a note to the company to see what they say. I will let you know if I get a response.
This has some pdf files on standard installation for your tub.

Thanks so much Fred! I will pass this along and keep you posted!

The message I got back from Wyndham was; please give me a call at: Christophe Blondeau 1-888-522-8476 . Hopefully, I have given you enough information that you can have a reasonable conversation with him yourself. If not, let me know and I will talk to him.
Unless, the tub will be permanently sealed to the floor, it may be light enough to move if bumped hard. This could break any fitting that is not flexible, so the flexible hose sounds like the best method so far.

Is this problem due to your slab being a post tension slab that can not be cut or cored? We had that problem when I bought a free standing tub that had a center drain whereas our old built in tub had the drain on the left end. I had to hire a structural engineer to locate the tension wires so we could chip out the area for the p trap, then had to raise the floor for the rest of the drain. I actually like the way it turned out, even though it was not part of the original plan.

@Depo SD: That floor looks great. Plus the slight step up gives a nice touch

This can happen. What is the distance from the slab now to the water level in the PTrap?

@Depo SD: I agree the way you did it is gorgeous-we just don't have the space to do that-that was the first suggestion. I think we have figured out how to get it installed thanks to everyone's help!

@mgolman do you mind sharing how you got around it? we are building in palm desert and are about to order almost the exact same tub and our contractor is saying we cannot put it on the concrete slab. I called wyndham manufacture of the tub and they agreed it may be a problem installing on a concrete slab as there is no way to inspect if it is leaking? he is suggesting a platform but I don't want to do that? what did you end up doing? thanks!

@homeaholic, if you look above, a couple of people gave us some good suggestions. We ended up doing a couple of things: we changed from a floor mount faucet to a wall mount, which solved the floor mount faucet problem. For the tub, after speaking to our architect-she said it can be done, it is just considerably more difficult but doable. We ultimately ended up utilizing four men to lower the tub onto the connection (?) very carefully. But your contractor is right in that there is a 99% chance it won't leak, but a 1% chance it will and they can't check it like normally. Anyways, ours has been fine and I love the tub!

thank you for getting back to me! I appreciate it :) I've seen it done there so I know it can be? will send the link to my contractor.

you should check out the rapid connect drain from Fleurco in their ARIA tub collection.
It will allow your contractor to easily install the tub by using the rapid connect drain

I am so glad I found this post. I also removed a built in jacuzzi tub with a left drain. I purchased a freestanding stone tub with a center drain because I was told the plumber could trench the floor and move the drain. As it turns out the tension wires in the foundation were in the exact place where the drain for a center drain freestanding tub would need to be relocated. BACK to the drawing board. I am now on the hunt for a Left/Reversible Drain Freestanding Tub. I actually PREFER an integrated overflow because I don't want that unsightly overflow drain sticking out of the end of the tub. Note: My plumber IS able to go deep enough into the foundation to move the drain a few inches to one side. So I need: Freestanding Tub without legs, Left/Reversible Drain, no longer than 63 inches, no higher than 25 inches, preferably an integral overflow but I can live an external overflow if I have to. My plumber says I also need a Toe Push Drain because he can't get underneath the tub once glued down to install a pop-up drain. If anyone can help, professional or otherwise, I would really appreciate it.

We were able to install a free standing tub on our slab, our problem is, the floor mount tub filler. Our plumber is saying that because we're on a slab, the supply hose is too long and they'd have to trench our build up the floor to let the hose have somewhere to hang. Aren't there different length supply hoses that we could simply switch out?

Lisabeth, how did you end up installing your tub? I have the same issue and my HOA does not allow us to make holes in the concrete flooring. I have the Wyndham 60" too.

munnie, the tub wasn't the problem for us, they were able to set the drain into the slab, however the free standing tub filler is the issue because the braided supply line is too long and nothing fits properly. They have to break open the concrete and refit the supply lines etc. If anyone has a better idea than having to do that, I'd love to hear.

cameronaw: did you find a solution??? we are building a home and running into the same problem... i'm looking for the exact same tub dimensions... any info is appreciated!

Lisabeth3 were you ever able to find a solution for the tub filler. We are currently building now and running into the same issue.

Installing on a salad is no longer a problem with a product from Fleurco called the rapid connect free standing tub connector.

it is specifically designed to accommodate this exact issue.

as long as you have plumbing to the area the rapid Connect will allow an easy installation of the tub.

the unit comes with a brass tailpiece that is simply attached to the drain from the tub.

once the rapid Connect has been installed you merely lift the tub a gently lower into place in the neoprene hole in the rapid connect.

great item,easy to install. Check out www.fleurco.com....rapid connect drain

Thank you for your response! To give you some background... we did rough in with a deck mounted tub originally planned but have now run into a space issue in the bathroom. You we need to run the tub perpendicular. So th original rough in for plumbing did not account for a floor mounted tub. Would this product still apply to us?

You have to relocate the plumbing in the slab. Jackhammer it and move it.

I am running into the same issue, my contractor says he has to move the drain in the concrete. Does any one know how much space is left underneath the tub to use a flex hose to drain. i am looking to get a center drain tub ~ 60x34.

No flex hoses. Remove concrete.

Hi RJ! That plumber made this way too complicated. if there was an existing tub sitting on a slab foundation, you removed it then you can go through the concrete move the drain over I have done it I don’t know how times and I am doing one right now and you have plenty room to work with the tub sounds like to me the plumber just doesn’t want to do anything that’s hard, sorry!
Once you have the tub in place the plumber with Mark where the drains need to go he will then bust through the concrete slab go down as far as he can to where he can maneuver the plumbing, reroute the plumbing to wear the new drain is going to be just like the one you have for the existing how it’s plumbed up for the old tub he does the same thing with the new. Then he will re-position the tub on there to make sure it fits and connect it run water that is properly draining right. Then he will remove the tub concrete the hole. Then you can have your tile guy or whoever is doing your flooring install your flooring. Oh yes he can reroute your plumbing underneath your slab as well if you want to install a freestanding tub filler. Not trying to be rude you need to find a new plumber so hard to find people that will get in there and do the work or do the job and get it done right. I am a general contractor and when my clients want something then I will do anything and everything in my power to get it done if I have to hire a structural engineer or other professionals to make sure it’s done right. if not then at least we tried. But in this case we’ve installed these way too many times the same way you’re having yours done. Sincerely CT, Texas

Hi CT, The tub will be on the basement concrete floor. The basement right now is unfinished with no walls, we currently have a plan for a 60" freestanding tub which can be extended to a different size tub so we can use the existing plumb line. The plumbing line is 45" from the wall, we paid the builder to rough in, i do not want to pay again to move this. Does next question will be, do these tubs require a P trap underneath?

All plumbing fixtures require a P trap. Jackhammering concrete is in your future.

How did this end?

like mentioned above by michaels414 - installation of freestanding tub no longer requires flex pipe as there are multiple products on the market like Fleurco that make it way less complicated.

Also, few people asked about tub filler, we are working on the basement bathroom that will have freestanding tub with freestanding filler/faucet. Faucet that we are installing is
Ancona Prima Floor Mount Bathtub Faucet. Our plan for the faucet is to get our plumbing pipes buried in the concrete inside 2" pvc with 2 openings: one right under the faucet fixture and another inside of the bathroom wall and an opening where shut-off valves will be placed. This will provide an ability to access and change the water pipes in the future in case of a damage. Also, this eliminates the problem of built-in faucet hoses being too long.

Need a solution when you cannot cut a hole in the concrete floor to move the drain. My p trap is embedded in the concrete. I have 4 1/2" clearance under the free standing tub. I need to move the drain about 1 foot. Can I use a right angle PVC connector attached to a 1 foot length of pipe and another right angle to the new drain position? Seems to me if I have 1/4" fall from the new tub drain to the existing drain opening in the concrete, it should work. Appreciate any guidance.
