Kohler Bathtub Installation


Hello everyone Have an interesting question about Kohler bathtub installation

Im planning to mount a Kohler faucet (K-T398-4) on the deck of a tub (Kohler K-6369). I have inch copper from the floor, and inch copper from the faucet (K-300-KR).

Since the area between the tub and tub-skirt is narrow and curved, I am planning to install x COP Male adapter on both ends and use a flexible washing machine supply line to connect the two ends.

Any issues/concerns? Any alternative option? Thanks

Why? Just use pex or copper.

Why does that surprise you ? especially where we live. Along with police and paid fireman, Union workers are known to do things that way.

On the Kohler tub listed the flexible connectors are required to assemble the tub when using a deck mount faucet. It's in the instructions. I've never done it with flex connectors, the ones I've done had floor mount tub fillers.

I dont see why the braided washing machine hoses wouldn't work.

I've used shark-bytes and pex to plumb a few but if there's no access to it it's gonna get copper-sweat.

I've done them with copper, pex, flex water supply lines and flex copper lines that were part of the faucet. Don't recall ever having one that required flex lines.

Sure washing machine hoses would work but wouldn't be on my list of options.

Re: Kohler Bathtub Installation


Tjbnwi is correct, the Kohler tub listed flexible connectors as a requirement. Called Kohler and confirmed.
I thought about flex copper line, but the homeowner wants to add options to the tub in the future. Which requires him to lift the inner-tub to install on the side of the wall. (Kohler has options to add music, sonic vibration, etc.).
Agree that washing machine hose won’t be my first choice, but I can’t find a technical reason not to! I think a high-quality stainless braided washing mashing machine hose would do the job. I know it is a weird choice!

Re: Kohler Bathtub Installation


That is a 2 piece plastic tub, installed one before a real POS, the drain supplied was a piece of flex pipe. Would not pass inspection had to cut hole in the ceiling below or chop up tiled floor.
The supply lines we got with the tub/faucet were white flex lines with plastic nuts, just terrible. People used it 2 or 3 times now it just takes up space.

All of the connections are between the 2 sections (inner/outer) when you put them together you hope they are not pinched.

Make sure the pipe adapters are for pipe to hose, not pipe to pipe if you use the washing machine hoses.

I know this one gets used every day.

Tub filler, I did not have to deal with the flex hose, no flex connection anywhere on the drain.

Re: Kohler Bathtub Installation


I have put in 2 both were sold by Kohler, one we know came from china. No name anywhere on it or box, but had Kohler sticker on it . It was an oval with the cheapest flex drain I have ever seen. Both had tub mounted faucets not floor mounted.

Is that one a 2 piece?

Yes, it is the Stargaze line. I recall the CoO on this one was Mexico, I know it wasn't China.

Well, I told the homeowner Im going with flex copper. He wasnt happy because more T&M and no easy way to add Kohler options later. I went back to my gut feeling as I want to stand by my work and integrity. Using washing machine hose just didn't feel right.

Re: Kohler Bathtub Installation


Question:

Does manufacturers installation instructions trump over county codes?

I've never seen this kind of tub so I'm a bit ignorant on the install.

I know they do in electrical installs. Not sure how it is written in the plumbing code.

What code do you feel is being violated?

The tub I posted the picture of is in Highlands Ranch CO. No code issues were brought up.
