How can i stop the water that splashes under my clawfoot tub from leaking into the apartment below me?

if you are renting you can never win in this sort of scenario. take baths only. That’s your only option if you are renting, because clawfoots are usually only in really old houses and buildings, it’s the owner’s problem, not yours, but you can make it easier by only taking baths.

If the grout is replaced that will help a lot but the shower curtain * should * be preventing most water seepage. How much water is seeping out? Is the shower curtain needing replacement?
If it is soaking through towels and into the downstairs apartment I would be very concerned about the condition of the supporting floor joists.

You know. I’d just keep on doing what your doing. The more the unit downstairs complains to your landlord the faster he’ll get it fixed.

They make shower curtains for tubs, that will drain the excess water into the tub.

Put down a rubber bottom mat with an absorbant top or a rubber mat topped by something that could absorb any water(unless it is high volume).Something like those sham wow towels ought to work. Between that and the before mentioned shower curtain, it should carry you until the landlord can install waterproofing.

The tile needs regrouting. That should solve the problem. If it doesn’t, then the floor needs to be retiled.

Do you have a circular shower rod over the tub? You need to use 2 or 3 shower liners, and make sure they are inside the tub when you take a shower. This will keep the water inside the tub.

The solution is to prevent water from escaping the tub in the first place—not just to keep it from seeping through the floor. A proper shower curtain should contain virtually every drop of water. Leakage around the drain should be fixed by a plumber.

Your landlord might be responsible for installing a suitable shower curtain system, such as

hi everyone, thanks for your responses so far!
i have two shower curtains surrounding the tub (with a circular shower curtain ring surrounding the tub), but water still splashes out. its a clawfoot so its a very narrow showering experience.

@seenmaker, you may need to add a third curtain, and make sure it’s tucked in when you shower. It’s a pain, because it does make it claustrophobic, and makes you keep showers short. Have you been able to identify exactly why the water comes out? Is the shower head not far enough over the tub to allow the water to hit you? Sometimes this happens if the landlord uses a modern shower head with a clawfoot tub. The space between the tub and the wall is more than with a conventional tub.

Maybe the water flow is too high? Try reducing the force of the stream & adjusting shower head (if possible) for narrower spread.

Put a tarp under your tub until it can be done properly with that edges built up a little. Then you can just towel up the extra. You must have major showers, though, that 2 curtains can’t keep inside.

i’m fat

@seenmaker Is it one of the tiny clawfoot tubs? Even if your size is an issue there has to be a way to work it so you can take a comfortable shower.

@seenmaker I know all about fat. This is not about fat. It is about an unresponsive landlord. Bathroom floors should be impermeable to water, and yours needs to be redone. You should be able to gain another 60 pounds, and take a shower with no curtain whenever you like.

@seenmaker I meant a powerful shower head!!!!

I agree with @pdworkin.
