I’m having a jacuzzi tub replaced with a freestanding tub and freestanding faucet. I have a concrete slab which has hot and cold water copper lines coming out of the slab. My Plummer originally told me there would be no issue installing the floor mounted faucet directly on the concrete slab /tile floor . After doing some preliminary work which i paid for they are now telling me that they that they cannot install the faucet on slab floor . Instead a box has to be built for the faucet to be mounted on . When I pressed them as to why it has to done this way the response was two fold.

One reason given is because of plumbing code they are not allowed to cover a water line shut off valve that is not accessible . Mind you they installed the shutoff valves when they trimmed back the water lines.

Second reason given is that they feel mounting the faucet on a box/platform is the better choice plumbing wise

I’ve never seen a freestanding faucet mounted on top of a platform/box nor can I find a picture when searching on the internet . Is this Plummer giving me accurate information or does this Plummer not want to do the hard work of breaking the slab so the faucet can be installed without a separate platform box

i/m not sure i understand your problem 100% ?
it sounds like you are correct and that the plumbers roughed in the water wrong ?
if you can provide a picture then we will all know for sure.

there are lots and lots of pictures on the internet and you are correct in that all show finished piping screwed into fittings below the floor not above it. (which is the way i do this type set-up)

Water line valves are installed in walls and "covered up" many times. Some faucets do need a box, but it is usually installed IN the concrete so it is not visible. Need more information about the make and model of faucet.

Why does it even need a shut-off? Most all common in-wall shower/tub valves don't have separate shut-off valves, why would you need one here? Sounds like you need a new plumber....why would you want a wooden box....

Not a plumber by trade but a fierce DIYer

It could be a plastic or metal one, if it comes with, or for, that faucet. Some exposed tub faucet risers DO have shutoffs on them.

Thanks

Below is a link to the tub filler make and model

You WILL require a box of some sort because you WILL need flexible connectors.

Personally, I would get a different faucet.

Until I saw HOW the "flexible" supplies are supposed to work, I would have said you needed female adapters at the floor level, but since the hoses are "longer" than that and cannot compress up into the faucet, I am not sure HOW you work them on a concrete floor, since you cannot make the connection below the floor, nor can you push the supply lines down under the floor.

The flexible connectors are part of the faucet as is the box, and tripod support.

hj,

the nightmare is worse than you think

Not really suitable for a concrete slab w/o building a 'raised deck' just for the faucet.

5 years from now, where can one get parts ?

IMO: the OP got taken by a pretty face

It is exactly like I supposed once I saw the drawings.

plain and simple....
the plumber put the pipes in the wrong location as well as the wrong height.
for the faucet that you chose there should be shutoffs in a remote location. there is no way to incorporate shutoffs without burying them in cement .

Unfortunately, with that faucet it appears the CONNECTIONS have to be below the floor which would make them "difficult" to connect with a concrete floor, when you cannot make the connections above the floor and then "push" them down under the floor.

Remote location for sure, unless inspector has a problem with that.

On a concrete slab, people thought it was very difficult to install a freestanding tub with a faucet. However, the main scenario is different from what people believed.

Freestanding tubs are very easy to install on a slab, and you can do it yourself to reduce the cost.

Don't forget to install the tub surround to avoid mold.
