Freestanding tub faucet connection advise

[dirtmover]

I'm looking for advice on connecting the water supply to a freestanding tub faucet. The risers terminate in 1/2" NPS (male) under the floor. Standard flex connectors are the obvious option but I'm not sure it's a good idea fully enclosing this type of hose under the floor. A secondary concern is that the restriction introduced by these hoses will impact the fill time. Tell me if I'm unduly concerned but is there a better, more robust, permanent way to transition from 1/2" copper to 1/2" NPS.

Flexible connections should not be installed in hidden spaces. You can get chromed nipples which would likely work. Regardless, the unit will need some bracing - either to the wall or the tub - it can't just be sticking up from the fitting in the floor. this often comes with the unit.

Yeah, this was my concern.

I cannot find anything like this. Do you have any links?

Yeah, I've got some flanges screwed to the floor to mount them in. They are solid.

There are MANY ways to connect a freestanding tub faucet, but the RIGHT one depends on the faucet and what you have to connect to AT THE FLOOR, NOT underneath it.

Yeah, this was one of the first hits I got when I searched for chrome nipple. Unfortunately I believe these are all tapered threads. I need straight with a gasket or cone washer to make the seal just like on these braided hoses that I can't use.

The risers are like these ones http://www.tubz.com/images/riobel/tu26.jpg from this page http://www.tubz.com/riobel-tub-faucets.htm. There is about 4" of NPS thread that goes THROUGH the floor which means that the supply MUST be connected BENEATH the floor.

Here is another similar example http://www.cheviotproducts.com/asset.../5100_3965.pdf "2. Lower riser tubes THROUGH the floor
3. BELOW floor, install other Tie Down Nut (leave loose and attach faucet) and then tighten tie down nuts, securing riser tubes to the floor.". The supply will be finally connected UNDER the floor.

Those manufacturers have a very simplistic concept for connecting their faucets. They assume EVERY installation has access below the floor when the faucet is installed. In fact, in most cases the house is well on the way to completion before the tub is installed, and slab floor installations NEVER have access under the floor.

I have an add on to this question. What is the best way to connect the drain for a free standing tub when there is no access to the drainage plumbing from underneath?
