Urgent help on leaking bath tub to kitchen
Hi, DIY gurus:

I have bought old house that has a leaking problem: when showing in the tub, the leakage drains to the kitchen below. I have no clue the leak could be from (tub crack, rusty pipes, faulty sealant on tiles, faucet connectors).
Q1: How do I check out where the culprit is/are? Do I open the dry wall ceiling of the kitchen or open from the side of the bath tub ?

Q2: How to fix it, Can it be DIYed?

Thank you

Is it a fiberglass tub?
Does it leak when there is water and no one in the tub, or only when someone is standing in the tub taking a shower?
If it flexible fiberglass and the weight of someone standing in the tub causes the tub to flex, the plumber's putty around the lip of the drain may have dried out allowing it to leak.
That can be fixed from the tub side.
If this is the case, let us know, and we'll tell you how to fix it.

Run just the tub spout being sure that no water splashes anywhere on the walls. If you still have a leak you've narrowed it down to the drain itself.

If that fixes the leak either the seal around the tub, the grout, or the pipe going to the shower head is leaking.

Look behind the round beauty plates on the shower controls. If there is a gap around the stems the water splashed in that area will leak down the inside of the wall. If so let things dry out a bit. Maybe help it dry with hairdryer. Then caulk the gaps around the stems thus sealing the area so water won't get through.

tub leak
Thank you all for your input.

The thing is that the leaking is intermittent, when several people showering in the tub, then the leaking happens after 2-3 people. but sometimes one shower up to 10minutes no leak, sometimes 4-5minutes the leak is like raining (4-5 places).

Although I can see apparent leaking in the stem for the water go up, but not sure it is the major leaking source.

would appreciate more advice. Thanks!

Could take 10 minutes for flow to reach kitchen. If there is air space around the stems behind the beauty plates water will get in there and travel down.
Don't forgo anywhere you see the water can go. Even if you don't think it major you need to address it.

Everyone showers differently. Some people will splash water on walls in a way that makes a leaky tub seal more evident and some people shower in such a way that you'd never know there was a hole there. Not that anyone is doing anything wrong but everyone stands in a different place in the tub, angles the shower head differently, has there body orientated a different way, has a different body shape, etc.

It also could be something where it takes the flow a long time to reach the kitchen as has been mentioned.
